Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options. The radius of the circle is 3 units. The center of the circle lies on the x-axis. The center of the circle lies on the y-axis. The standard form of the equation is (x – 1)² + y² = 3. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
Answer:
Correct options are A, B, E--------------------------
Standard form for the equation of a circle is:
(x − h)² + (y − k)² = r², where (h, k) is the center and r is the radiusConvert the given equation into standard form:
x² + y² - 2x - 8 = 0x² - 2x + 1 + y² - 9 = 0(x - 1)² + y² = 9(x - 1)² + y² = 3²Its center is ( 1, 0) and radius is r = 3.
Let's verify the statements:
A) The radius of the circle is 3 units - TRUE, r = 3;B) The center of the circle lies on the x-axis - TRUE, point (1, 0) is on the x-axis;C) The center of the circle lies on the y-axis - FALSE, the x- coordinate of the center is not zero; D) The standard form of the equation is (x – 1)² + y² = 3 - FALSE, r²= 9 but not 3;E) The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9, TRUE, its radius is r² = 9 ⇒ r = 3.Answer:
See below
Step-by-step explanation:
To find:-
Which statements are true .Answer:-
The given equation of the circle is ,
[tex]\longrightarrow x^2+y^2-2x-8 = 0 \\[/tex]
For finding the correct statements , we need to convert this equation into standard form for a circle.
The standard equation of circle is given by,
[tex]\boxed{\begin{tabular}{c}\textbf{\underline{ \red{Standard\ equation\ of \ circle }}} \\ \\ \text{ The standard equation of a circle is given by:-} \\\\ \longrightarrow \underline{\underline{ (x-h)^2+(y-k)^2 = r {}^{2}}} \\\\ \text{where} , \\\\ \bullet\text{ (h,k) is the centre of the circle.}\\\\\bullet\text{ "r" is the radius of the circle. }\\\end{tabular}}[/tex]
Now for that we need to complete the square for "x" . This can be done by ,
Rearrange the terms,
[tex]\longrightarrow x^2-2x + y^2-8 = 0 \\[/tex]
Add and subtract 1² .
[tex]\longrightarrow ( x^2 -2x +1^2 ) - 1^2 + y^2-8=0 \\[/tex]
Simplify,
[tex]\longrightarrow (x^2-2(1)x+1^2) - 1-8 + y^2=0 \\[/tex]
Notice that the terms inside the small brackets are in the form of a² - 2ab + b² , which is the whole square of (a-b) . So we can write it as,
[tex]\longrightarrow (x-1)^2 +y^2 - 9 = 0 \\[/tex]
Add 9 on both the sides ,
[tex]\longrightarrow (x-1)^2 + y^2 = 9\\[/tex]
This can be written as,
[tex]\longrightarrow \underline{\underline{ \boldsymbol{(x-1)^2+(y-0)^2 = 3^2}}} \\[/tex]
On comparing it to the standard form, we have;
[tex]\longrightarrow\boxed{ \text{Center = (1,0) }} \\[/tex]
[tex]\longrightarrow\boxed{ \text{ Radius = 3 \ units}} \\[/tex]
Let's check the given statements ,
Statement 1: The radius of the circle is 3 units.
This statement is true as we just calculated the radius to be 3 units.Statement 2: The centre of the circle lies on the x-axis.
This statement is also true as you can see that the y coordinate to the centre is 0 , and the x coordinate is 1 , so it will be on x-axis .Statement 3: The statement of the circle lies on the y-axis.
This statement is false since in the previous statement we proved that the centre lies on the x-axis .Statement 4: The standard equation of the circle is (x-1)²+y² = 3
This statement is false as we calculated the value of r² to be 9 .Statement 5: The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
The given equation of circle is x² + y² = 9 , if we convert this into standard form, we will get ; x² + y² = 3² . Now on comparing it to the standard equation, we see that the radius is 3 units . Hence the given statement is also true .The graph for the same has been attached.
Please help I need these differential equations done by today and cannot do it.
the particular solution to the differential equation. we use the positive sign: [tex]y = -1 + e^(1/2 x^2 + x - 5.605)[/tex]
What is the differential equation?To find the particular solution to the differential equation {dy}/{dx} = (x+1) (y+1) with the initial condition y(4) = 3, we can use separation of variables and integration.
First, we can rewrite the equation as:
[tex]{1}/{(y+1)} dy = (x+1) dx[/tex]
Next, we can integrate both sides:
[tex]∫ {1}/{(y+1)} dy = ∫ (x+1) dx[/tex]
[tex]ln|y+1| = 1/2 x^2 + x + C[/tex]
where C is the constant of integration.
To determine the value of C, we can use the initial condition y(4) = 3:
[tex]ln|3+1| = 1/2 (4)^2 + 4 + C[/tex]
[tex]ln|4| = 10 + C[/tex]
[tex]C = ln|4| - 10 = -5.605[/tex]
Therefore, the particular solution to the differential equation with the initial condition y(4) = 3 is:
[tex]ln|y+1| = 1/2 x^2 + x - 5.605[/tex]
Solving for y:
[tex]|y+1| = e^(1/2 x^2 + x - 5.605)[/tex]
[tex]y+1 = \pm e^(1/2 x^2 + x - 5.605)[/tex]
[tex]y = -1 \pm e^(1/2 x^2 + x - 5.605)[/tex]
Since [tex]y(4) = 3[/tex], we can determine which sign to use:
[tex]3 = -1 + e^(1/2 (4)^2 + 4 - 5.605)[/tex]
[tex]3 = -1 + e^(7.395)[/tex]
[tex]4 = e^(7.395)[/tex]
Therefore, we use the positive sign: [tex]y = -1 + e^(1/2 x^2 + x - 5.605)[/tex]

A rectangular prism has a base area of 54 m (to the 2nd power) and a volume of 702 m (to the 3rd power). What is its height?
Answer:
13 meters.
Step-by-step explanation:
We can use the formula for the volume of a rectangular prism, which is:
Volume = length x width x height
We are given that the base area (length x width) of the prism is 54 m², so we can write:
length x width = 54 m²
We are also given that the volume of the prism is 702 m³, so we can write:
Volume = length x width x height = 702 m³
We want to find the height of the prism, so we can rearrange the formula for the volume to solve for height:
height = Volume / (length x width)
Substituting the given values, we get:
height = 702 m³ / 54 m²
Simplifying this expression, we can divide both the numerator and the denominator by the greatest common factor of 54 and 702, which is 18:
height = (702/18) m / (54/18) m = 39 m / 3 m
height = 13 meters
Therefore, the height of the rectangular prism is 13 meters.
An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $5800 and her stock in Company B was worth $7470. The stock in Company A has decreased 1% since last year and the stock in Company B has decreased 20%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).
To find the total percentage decrease, we first need to find the new values of the stocks in Company A and Company B after the decrease.
The new value of the stock in Company A is: $5800 - (1% \times $5800) = $5742
The new value of the stock in Company B is: $7470 - (20% \times $7470) = $5976
To find the total value after the decrease, we add these two values: $5742 + $5976 = $11718
To find the percentage decrease from the original total value ($5800 + $7470 = $13270) to the new total value ($11718), we use the formula:
percentage decrease = [(original value - new value) / original value] x 100%
percentage decrease = [($13270 - $11718) / $13270] x 100%
percentage decrease = 11.7%
Therefore, the total percentage decrease in the investor's stock account is 11.7%.

If <1 and <2 are vertical angles and m<22 = 180°, find m<1
If ∠1 and ∠2 are vertical angles and m∠22 = 180°, then m∠1 = 90°
Vertical angles are pairs of angles that are opposite to each other when two lines intersect. Vertical angles are always equal in measure. Therefore, if ∠1 and ∠2 are vertical angles, then:
∠1 = ∠2
We are also given that m∠22 has a measure of 180°. Since ∠1 and ∠2 are vertical angles, they form a straight line, and their measures add up to 180°. Therefore:
∠1 + ∠2 = 180°
Since ∠1 = ∠2, we can substitute ∠1 for ∠2 in the above equation:
∠1 + ∠1 = 180°
Simplifying the equation, we get:
2∠1 = 180°
Dividing both sides by 2, we get:
∠1 = 90°
Therefore, ∠1 has a measure of 90°.

Describe equation?
A mathematical equation is a formula that uses the equals symbol (=) to denote the equality of two expressions.
A formula would be 3x - 5 = 16,
for instance. We may determine the value of the variable x by solving this equation: x = 73.
The slope-intercept representation of the equation can be used to determine the equation of a line running through the points (x1, y1) and (x2, y2):
y - y1 = m(x - x1) (x - x1)
where m is the line's slope. The following formula can be used to determine the line's slope:
m = (y2 - y1) / (x2 - x1) (x2 - x1)
Now put the x and y value in this:
slope of the line using the points (1, 5) and (3, 11):
m = (11 - 5) / (3 - 1) = 6 / 2 = 3
We can use the slope of the line to determine the equation of the line now that we know it:
y - y1 = m(x - x1) (x - x1)
y - 5 = 3(x - 1) (x - 1)
y - 5 = 3x - 3 = 3x + 2
In light of this, the equation for the line connecting points (1, 5) and (3, 11) is y=3x+2
To determine the value of y for x = 7, we can utilize the equation of the line we discovered earlier:
y = 3x + 2

a river starts by flowing south about 1.1x10 to the seventh power then it flows southeast for about 3.2x10 to the sixth power ft before it empties into the ocean. what is the length of the river? write your answer using scientific notation show your work
1.143 x 10⁷ ft, or approximately 11.43 million feet is the length of the river.
To find the length of the river, we need to use the Pythagorean theorem, which states that the square of the length of the hypotenuse (the diagonal line connecting the two endpoints of a right triangle) is equal to the sum of the squares of the lengths of the other two sides.
Let's call the length of the southward flowing part of the river "a" and the length of the southeastward flowing part of the river "b". Then we have:
a = 1.1 x 10⁷ ft
b = 3.2 x 10⁶ ft
The length of the river is given by the hypotenuse of a right triangle with sides a and b. Therefore, we can calculate the length of the river, c, as follows:
c² = a² + b²
c² = (1.1 x 10⁷ ft)² + (3.2 x 10⁶ ft)²
c² = 1.21 x 10¹⁴ ft² + 1.024 x 10¹³ ft²
c² = 1.3104 x 10¹⁴ ft²
c = √(1.3104 x 10¹⁴ ft²)
c = 1.143 x 10⁷ ft
Therefore, the length of the river is 1.143 x 10⁷ ft, or approximately 11.43 million feet

Evaluate the triple integral?To evaluate the triple integral f 1 dv where f = {(x, y, z) | 0 ≤ x ≤ 2, 0 ≤ y ≤ 4 − x^2, 0 ≤ z ≤ 4 − x²},
Set up the triple integral
The triple integral is written as ∭(1) dV, with the limits of integration for x, y, and z as given in the problem.
Integrate with respect to z
∫(∫(∫(1) dz) dy) dx
The limits for z are 0 to 4-x², so integrate with respect to z:
∫(∫[(z)|from 0 to 4-x²] dy) dx
Substitute the limits for z
∫(∫[(4-x²)] dy) dx
Integrate with respect to y
∫[(4-x²)y|from 0 to 4-x²] dx
Substitute the limits for y
∫[(4-x²)²] dx
Integrate with respect to x
Integrate the function with respect to x:
∫(16 - 16x² + x⁴) dx from 0 to 2
Substitute the limits for x
[4x³/3 - 16x³/3 + x⁵/5]|
from 0 to 2
Calculate the final result
(4(2)³/3 - 16(2)³/3 + (2)⁵/5) - (0) = (32/3 - 128/3 + 32/5) = 8/15
So, the triple integral evaluates to 8/15.

4. if an athlete eats a large meal before a competition, how many hours before the competition should she finish eating? a. 1 hour b. 1.5 hours c. 2 hours d. 2.5 hours e. 3 hours
Option D is the correct option i.e., 2.5 hours. Timing is everything when it comes to dining before a fight. Athletes must ingest enough calories to power their efforts without developing gastrointestinal pain or bloating while competing. Typically, a substantial dinner should be eaten two to three hours prior to the game.
The body needs time to process and assimilate nutrients, which is the cause of this. A big dinner requires the body to divert a lot of blood flow to the digestive system, which can have an impact on an athlete's performance. Athletes' performance can be hampered by sluggishness, gastrointestinal pain, or even vomiting brought on by eating too close to a competition.
In general, it is recommended that athletes experiment with different meal timings and types of food during their training to determine what works best for their individual needs.
They should also consider the length of the event and the intensity of their activity to determine the amount and timing of their meals. A registered dietitian or sports nutritionist can help athletes create a personalized nutrition plan to optimize their performance.

the variance of a sample of 144 observations equals 576. the standard deviation of the sample equals group of answer choices 12. 63,504. 21. 441.
The sample's standard deviation is equal to 12. Thus, choice B is the right choice.
The variance of a sample of 144 observations equals 576.
Variance S² = 144
The standard deviation is a measure of how spread out a set of data is. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean.
The standard deviation can be used to measure the amount of variation or dispersion of a set of data values from the mean.
Standard Deviation = √Variance
Standard Deviation = √144
Standard Deviation = 12
The standard deviation of the sample equals 12. So the option B is correct.

Find the area of the Trapezoid
24mi
8.2mi
9 mi
9.7mi
please explain I'll mark brainlisest
Answer:
A = 46.74 mi²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{h}[/tex] (b₁ + b₂ )
where h is the perpendicular height between the bases b₁ and b₂
here h = 8.2 , b₁ = 9 , b₂ = 2.4
then
A = [tex]\frac{1}{2}[/tex] × 8.2 × (9 + 2.4) = 4.1 × 11.4 = 46.74 mi²

Find the measure of the missing angle and arc
It is important to carefully read and understand the information given in the problem, as well as to apply the appropriate formulas and properties to find the solution
Sure, I'll be happy to help you with your question. In order to find the measure of the missing angle and arc, we first need to know what type of angle and arc we are dealing with. If it is a central angle and arc, then the measure of the angle is equal to the measure of the arc. However, if it is an inscribed angle and arc, then the measure of the angle is half the measure of the arc.
Once we have determined the type of angle and arc, we can use the given information to solve for the missing measure. For example, if we are given the measure of the angle and the measure of the arc, we can use the formula for the measure of a central angle or inscribed angle to solve for the missing measure.
Alternatively, we can also use the properties of circles, such as the fact that the sum of the angles in a triangle is 180 degrees and the fact that the angle at the center of a circle is twice the angle at the circumference, to solve for the missing measure.
In any case, . With enough practice and familiarity with these concepts, you can become proficient at solving problems involving missing angles and arcs.
