Answer:
z = 8Step-by-step explanation:
To find:-
The value of z .Answer:-
We are here given that the right angle is made up of two angles viz 8z° and (3z+2)° .
As we know that the measure of a right angle is 90° , so the sum of the two angles would also be 90° . Hence here ,
→ 8z + 3z + 2 = 90
→ 11z + 2 = 90
→ 11z = 90-2
→ 11z = 88
→ z = 88/11
→ z = 8
Hence the value of z is 8 .
[tex]\lim_{t\to 0} \det\left(\begin{bmatrix} \displaystyle \int_0^t \frac{u}{\sinh(u)} du & \cos(t) & \displaystyle \sum_{n=1}^{\infty} \frac{1}{n+t+i} \\ \displaystyle \frac{d}{dt} \left(e^t \ln \left(\frac{1}{t}\right) \right) & \binom{5}{2} t^2 & \displaystyle \prod_{n=1}^4 \left(\sqrt{1+nt} - 1\right) \\ i\binom{5}{3} t^3 \sin(2t) & \displaystyle \sum_{n=1}^{5} n^2 e^{int} & \binom{8}{2} t^2 + i\binom{5}{2} t^3 \cos(3t) \end{bmatrix}\right)[/tex]
The limit of the determinant as [tex]t[/tex] approaches 0 is [tex]-\infty[/tex].
To evaluate this limit, we can use the fact that the determinant is a linear function of each row, and that the limit of a sum is the sum of the limits. Therefore, we can compute the limit of each row separately.
Starting with the first row, we have:
[tex]\lim_{t\to 0} \int_0^t \frac{u}{\sinh(u)} du
= \lim_{t\to 0} \frac{\int_0^t \frac{u}{\sinh(u)} du}{t} \cdot t
= \lim_{t\to 0} \frac{\frac{t}{\sinh(t)} - 1}{t} \cdot t
= \lim_{t\to 0} \frac{1-\sinh(t)}{t\sinh(t)} = 1[/tex]
[tex]\lim_{t\to 0} \cos(t)
= 1[/tex]
[tex]\lim_{t\to 0} \sum_{n=1}^{\infty} \frac{1}{n+t+i}
= \sum_{n=1}^{\infty} \lim_{t\to 0} \frac{1}{n+t+i}
= \sum_{n=1}^{\infty} \frac{1}{n+i}
= \psi(i+1) \approx 0.643 + 0.41i[/tex]
where [tex]\psi(z)[/tex] is the digamma function.
Therefore, the limit of the first row is [tex]1 \cdot 1 \cdot \psi(i+1) = \psi(i+1)[/tex].
Moving on to the second row, we have:
[tex]\lim_{t\to 0} \frac{d}{dt} \left(e^t \ln \left(\frac{1}{t}\right) \right)
= \lim_{t\to 0} \frac{e^t}{t} - \lim_{t\to 0} \frac{e^t}{t^2}
= 1 - \infty = -\infty[/tex]
[tex]\lim_{t\to 0} \binom{5}{2} t^2
= 0[/tex]
[tex]\lim_{t\to 0} \prod_{n=1}^4 \left(\sqrt{1+nt} - 1\right)
= \prod_{n=1}^4 \lim_{t\to 0} \left(\sqrt{1+nt} - 1\right)
= \prod_{n=1}^4 \sqrt{1+n} - 1
= 4\sqrt{2} - 5[/tex]
Therefore, the limit of the second row is [tex]-\infty \cdot 0 \cdot (4\sqrt{2} - 5) = 0[/tex].
Finally, for the third row, we have:
[tex]\lim_{t\to 0} i\binom{5}{3} t^3 \sin(2t) = 0[/tex]
[tex]\lim_{t\to 0} \sum_{n=1}^{5} n^2 e^{int}
= \sum_{n=1}^{5} n^2 \lim_{t\to 0} e^{int}
= \sum_{n=1}^{5} n^2
= 55[/tex]
[tex]\lim_{t\to 0} \binom{8}{2} t^2 + i\binom{5}{2} t^3 \cos(3t) = 28[/tex]
Therefore, the limit of the third row is [tex]0 \cdot 55 \cdot 28 = 0[/tex].
Putting everything together, we get:
[tex]\lim_{t\to 0} \det\left(\begin{bmatrix} \displaystyle \int_0^t \frac{u}{\sinh(u)} du & \cos(t) & \displaystyle \sum_{n=1}^{\infty} \frac{1}{n+t+i} \\ \displaystyle \frac{d}{dt} \left(e^t \ln \left(\frac{1}{t}\right) \right)
& \binom{5}{2} t^2 & \displaystyle \prod_{n=1}^4 \left(\sqrt{1+nt} - 1\right) \\ i\binom{5}{3} t^3 \sin(2t) & \displaystyle \sum_{n=1}^{5} n^2 e^{int} & \binom{8}{2} t^2 + i\binom{5}{2} t^3 \cos(3t) \end{bmatrix}\right) = \det\left(\begin{bmatrix} \psi(i+1) & 1 & 0 \\ -\infty & 0 & 4\sqrt{2}-5 \\ 0 & 55 & 28 \end{bmatrix}\right) = -\infty[/tex]

3. What is the relationship between AC and CB? Explain.
4. True or False? Because BD is the angle bisector of ABC, AB = CB
1. The Similarity between AD and AB is that AD is half the length of AB.
2. The areas of triangles ACD and BDC are equal.
3. We can say that if AC is the longest side, then CB is the shortest side
4. False, The relationship between AD and AB is that AD is half the length of AB.
What do you mean by Triangle?A triangle is a three-sided polygon, which has three vertices. The three sides are connected with each other end to end at a point, which forms the angles of the triangle. The sum of all three angles of the triangle is equal to 180 degrees.
1) Since D is the midpoint of AB, we know that AD and DB have the same length. Therefore, we can say that:
AD = DB
Substituting AB for AD + DB, we can simplify to:
AB = AD + AD
or
AB = 2AD
So, the relationship between AD and AB is that AD is half the length of AB.
2) The areas of triangles ACD and BDC are equal, and we can write:
Area of ACD = (1/2) * AC * AD
Area of BDC = (1/2) * BC * DB
Since AD = DB, we can substitute and get:
Area of BDC = (1/2) * BC * AD
So, we can see that the areas of ACD and BDC are equal, and their bases AD and DB have the same length. Therefore, triangles ACD and BDC are equal in area and shape (they are congruent).
3) we can say that if AC is the longest side, then CB is the shortest side

The rival football team is predicted to score 35 points at the next game. How many field
goals (3 points) and how many touchdowns (assume 7 points) does your team need to
score in order to win? Let f = field goal and t = touchdown. Create an inequality to
represent this situation and determine values for the variables in an organized way that
makes your inequality true. List at least 3 possible game winning combinations and
justify your answer.
To win the game, your team needs to score more than [tex]35[/tex] points, which means: 3f + 7t > 35 three possible game-winning combinations are:
[tex]t = 5, f = 11: 3(11) + 7(5) = 63[/tex]
[tex]t = 6, f = 8: 3(8) + 7(6) = 62[/tex]
[tex]t = 7, f = 5: 3(5) + 7(7) = 56[/tex]
Each of these combinations would result in your team scoring more than 35 points and winning the game.
What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=).
For example, the argument [tex]"2x + 3 = 9"[/tex] asserts that the phrase [tex]"2x + 3"[/tex] equals the number "9." The purpose of equation solving is to determine the value or values of the variable(s) that allows the equation to be true.
Equations can be simple or complicated, regular or nonlinear, and include one or more elements. The variable x is raised to the second power in the equation. [tex]"x2 + 2x - 3 = 0."[/tex] Lines are utilised in many different areas of mathematics, such as algebra, calculus, and geometry.
Let's let f be the number of field goals scored by your team and t be the number of touchdowns scored by your team.
a) To win the game, your team needs to score more than 35 points, which means:
3f + 7t > 35
We can simplify this inequality by dividing both sides by 1:
3f + 7t/1 > 35/1
3f + 7t > 35
b) Now, we need to find possible values for f and t that make this inequality true. Since we are looking for positive integer values for f and t, we can start by testing different values for t and solving for f:
If t = 5, then 3f + 7(5) > 35, so 3f > 0 and f > 0. Possible solutions are f = 1, f = 2, f = 3, and so on.
If t = 6, then 3f + 7(6) > 35, so 3f > 7 and f > 2. Possible solutions are f = 3, f = 4, f = 5, and so on.
If t = 7, then 3f + 7(7) > 35, so 3f > 14 and f > 4. Possible solutions are f = 5, f = 6, f = 7, and so on.
c) So, three possible game-winning combinations are:
[tex]t = 5, f = 11: 3(11) + 7(5) = 63[/tex]
[tex]t = 6, f = 8: 3(8) + 7(6) = 62[/tex]
[tex]t = 7, f = 5: 3(5) + 7(7) = 56[/tex]
Each of these combinations would result in your team scoring more than 35 points and winning the game.

Calculate the come tax on salary of Birr 5200. Derive formule to calculate income tax and on Birr x, in terms of x. here x falls on the interval 5251 to 7800
the income tax payable on a salary of Birr 5200 is Birr 320.
In Ethiopia, income tax is calculated based on a progressive tax system where the tax rate increases as the taxable income increases. The formula for calculating income tax on monthly salary is as follows:
Taxable income = Gross monthly salary - Deductions
Tax payable = Tax rate * (Taxable income - Tax threshold) - Allowances
Where:
1. Gross monthly salary: Total salary before any deductions.
2. Deductions: Includes mandatory deductions such as employee social security contributions, pension contributions, and other authorized deductions.
3. Taxable income: Gross monthly salary minus deductions.
4. Tax rate: The percentage of tax applicable to the taxable income based on the tax bracket.
5. Tax threshold: The minimum amount of taxable income before tax is applicable.
6. Allowances: Includes authorized tax deductions such as dependant's allowance and other authorized allowances.
To calculate the income tax on a salary of Birr 5200, we need to determine the taxable income first. Let's assume that the gross monthly salary is Birr 5200, and there are no deductions.
Taxable income = Birr 5200 - 0 = Birr 5200
Next, we need to determine the tax rate applicable to this taxable income based on the tax bracket. For the taxable income range of Birr 5251 to 7800, the tax rate is 10%. Therefore, the tax rate applicable to Birr 5200 is 10%.
Tax rate = 10%
Now, we need to determine the tax threshold and the allowances applicable to this taxable income. Let's assume that the tax threshold is Birr 2000, and there are no allowances.
Tax threshold = Birr 2000
Allowances = 0
Using the formula mentioned earlier, we can calculate the income tax payable as follows:
Tax payable = 10% * (Birr 5200 - Birr 2000) - 0
Tax payable = Birr 320
Therefore, the income tax payable on a salary of Birr 5200 is Birr 320.
To derive the formula to calculate income tax on Birr x, we can use the same formula mentioned earlier. We can express the formula in terms of x as follows:
Taxable income = x - Deductions
Tax payable = Tax rate * (Taxable income - Tax threshold) - Allowances
Where:
1. x: Gross monthly salary.
2. Deductions: Includes mandatory deductions such as employee social security contributions, pension contributions, and other authorized deductions.
3. Taxable income: Gross monthly salary minus deductions.
4. Tax rate: The percentage of tax applicable to the taxable income based on the tax bracket.
5. Tax threshold: The minimum amount of taxable income before tax is applicable.
6. Allowances: Includes authorized tax deductions such as dependant's allowance and other authorized allowances.
We can use this formula to calculate the income tax payable on any salary falling within the Birr 5251 to 7800 taxable income range.
In conclusion, income tax in Ethiopia is calculated based on a progressive tax system, where the tax rate increases as the taxable income increases. To calculate income tax on a salary of Birr 5200, we need to determine the taxable income, tax rate, tax threshold, and allowances applicable to that salary. We can use the same formula to calculate income tax on any salary within the Birr 5251 to 7800 taxable income range.

Using the point-slope form of the equation of a line. the x-intercept of the line is [tex]-2.5[/tex].
What is the intercept of the line?To find the x-intercept of the line, we need to find the point where the line intersects the x-axis. We know that the y-coordinate of this point is zero, because it is on the x-axis. Let's call the x-coordinate of this point "x".
We also know that the line passes through the point (-2.5,0), because it is 2.5 units to the left of the origin. Using the point-slope form of the equation of a line, we can write the equation of the line as:
[tex]y - 0 = m(x - (-2.5))[/tex]
where m is the slope of the line. To find the slope, we can use the fact that the line passes through the point [tex](0,1)[/tex] and [tex](-2.5,0)[/tex]:
[tex]m = (1 - 0) / (0 - (-2.5)) = 1 / 2.5 = 0.4[/tex]

Ryan and Kayley launch their rockets at the same time. The height of Ryan’s rocket, in
meters, is given by the function () = −3.4
2 − 64, where x is the number of seconds
after the launch. The height of Kayley’s rocket, in meters, is given by the function
() = −3.4
2 − 25 − 45 where x is the number of seconds after the launch.
Algebraically find the moment when the rockets are at the same height, and then use that
to calculate the height. Round to the nearest hundredth. Show all work.
At the moment when the rockets are at the same height, their height is approximately -223.34 meters. Note that this negative value indicates that they are both below the ground level.
How to find moment?
To find the moment when the rockets are at the same height, we need to set the two height functions equal to each other and solve for x:
-3.4x²- 64 = -3.4x² - 25x - 45
Simplifying and rearranging:
0 = 25x + 19
x = -19/25
So the rockets are at the same height after -19/25 seconds, or about 0.76 seconds.
To find the height at this moment, we can plug this value of x into either of the height functions. Let's use Ryan's function:
h(-19/25) = -3.4(-19/25)²- 64
= -3.4(361/625) - 64
= -223.34
So at the moment when the rockets are at the same height, their height is approximately -223.34 meters. Note that this negative value indicates that they are both below the ground level.

A ferris wheel can accommodate 60 people in 25 minutes. How many people
could ride the ferris wheel in 4 hours? What was that rate per hour?
The rate per hour for the ferris wheel is 144 people per hour.
What is rate per hour?Your pay for each hour of labour is expressed as an hourly rate. You might need to estimate your income for other applications or modify your personal budget after comparing the hourly and salaried pay rates.
The ferris wheel can accommodate 60 people in 25 minutes.
To find out how many people could ride the ferris wheel in 4 hours, we need to convert 4 hours to minutes, since the given rate is in minutes.
1 hour = 60 minutes
4 hours = 4 x 60 minutes = 240 minutes
So, in 4 hours, the ferris wheel could accommodate 240/25 = 9.6 (rounded to the nearest whole number) cycles of 60 people.
The total number of people that could ride the ferris wheel in 4 hours would be 9.6 x 60 = 576 people.
Now, to find the rate per hour, we divide the total number of people (576) by the number of hours (4):
Rate per hour = Total number of people / Number of hours
Rate per hour = 576 / 4 = 144 people/hour
Therefore, the rate per hour for the ferris wheel is 144 people per hour.

1. The table lists the length of time in seconds it takes for each student in Ms. Sousa's class to say the alphabet. Make a line plot of the data. 2. Meghan says the difference between the least amount of time it takes a student to say the alphabet and the greatest amount of time is 4 seconds. Do you agree? Explain.
Answer:
The file is attached below.
I disagree with Meghan.
Step-by-step explanation:
Hello!
The line plot is attached below.
I disagree with Meghan as the least amount of time someone recited the alphabet is 4 seconds and the greatest is 7.5 seconds.
The difference between these two numbers would be 3.5 seconds, which is not the same as 4 seconds.
Suppose you just received a shipment of fourteen televisions. Two of the televisions are defective. If two televisions are randomly selected, compute the probability that both televisions work. What is the probability at least one of the two televisions does not work.
The probability that both televisions work is ___
Answer: The probability that both televisions work is approximately 0.746, or 74.6%.
Step-by-step explanation:
To calculate the probability that both televisions work, we need to find the probability of selecting a working television, and then multiply that by the probability of selecting another working television from the remaining televisions.
Since 2 out of the 14 televisions are defective, that means there are 12 working televisions out of 14. So the probability of selecting a working television on the first draw is 12/14.
After the first television is selected, there will be 13 televisions left, with 11 working televisions. So the probability of selecting a second working television is 11/13.
Therefore, the probability that both televisions work is:
(12/14) x (11/13) = 0.746
So the probability that both televisions work is approximately 0.746, or 74.6%.
To calculate the probability that at least one of the two televisions does not work, we can use the complement rule. The complement of the event "both televisions work" is the event "at least one television does not work."
So, the probability that at least one television does not work is:
1 - 0.746 = 0.254
So the probability that at least one television does not work is approximately 0.254, or 25.4%.
Answer:
0.60, 0.40
Step-by-step explanation:
The probability that a television works is 11/14. The probability that a television is
defective is 3/14.
The probability that the first TV works and the second works is
[tex]\frac{11}{14}[/tex]×[tex]\frac{10}{13}[/tex]
(If the first selected TV works, the total number of televisions left is 13, and the
the number of working TV is 10).
Answer: 0.60.
The event that at least one of the two televisions does not work is the
opposite of the event ‘both TV work’. So the probability of at least one of the
two televisions does not work is
1- Pr (both works)= 1 − 11/14 ∙ 10/13 = 0.40.
Answer: 0.40.
Suppose that Mars rotates on its axis once every hours. The equator lies on a circle with a diameter of miles.
(a) Find the angular speed of a point on its equator in radians per day ( hours).
(b) Find the linear speed of a point on the equator in miles per day.
Do not round any intermediate computations, and round your answer to the nearest whole number.
The answer of the given question based on the Angular speed is (a) the angular speed of a point on Mars' equator is π/2 radians per day. (b) the linear speed of a point on the equator of Mars is approximately 889.33 miles per day.
What is Linear speed?Linear speed, also known as tangential speed, is the distance traveled by an object in a straight line per unit of time. It is the speed at which an object is moving along its path, tangent to the path at any given point. Linear speed is calculated by dividing the distance traveled by the time taken to travel that distance. The units of linear speed are typically expressed in meters per second (m/s), miles per hour (mph), or kilometers per hour (km/h), depending on the system of measurement used.
(a) The angular speed of a point on Mars' equator is the angle (in radians) that a point on the equator sweeps out as Mars rotates on its axis. Since Mars completes one rotation every 24 hours, the angular speed is:
angular speed =(2πradians)/ (24 hours)= π/12radians per hour
To find the angular speed in radians per day, we need to multiply by the number of hours in a day:
angular speed = (π/12 radians per hour) * (24 hours per day) = π/2 radians per day
Therefore, the angular speed of a point on Mars' equator is π/2 radians per day.
(b) The linear speed of a point on the equator is the distance traveled by a point on the equator in a certain amount of time. The distance traveled by a point on the equator in one rotation is equal to the circumference of the circle with a diameter of miles, which is:
C = πd = π(6794) ≈ 21343.98 miles
Since Mars rotates once every 24 hours, a point on the equator travels the circumference of the circle in 24 hours. Therefore, the linear speed of a point on the equator in miles per day is:
v = C/24 ≈ 889.33 miles/day
So the linear speed of a point on the equator of Mars is approximately 889.33 miles per day.

Over what interval is the graph of y = |x + 6| decreasing? A. (–∞, –6) B. (–∞, 6) C. (–6, ∞) D. (6, ∞)
The function is decreasing for x < -6, or over the interval (–∞, –6).
What is a graph?
In computer science and mathematics, a graph is a collection of vertices (also known as nodes or points) connected by edges (also known as links or lines). Graphs are often used to represent relationships between objects or to model complex systems.
The derivative of the function y = |x + 6| is equal to -1 for x < -6 and 1 for x > -6. At x = -6, the derivative is undefined, but the function is not decreasing there, so we don't need to consider that point.
Thus, the function is decreasing for x < -6, or over the interval (–∞, –6). Therefore, the answer is A. (–∞, –6).
