The equation of the line perpendicular to the given line passing through the point   [tex](-2, 3)[/tex] is  [tex]y = -3/2 x + 15/2[/tex] , which is not one of the options provided.

What is the perpendicular to the line?

To find the equation of a line parallel to a given line, we need to use the fact that parallel lines have the same slope.

The given line has a slope of  [tex]2/3,[/tex]so the parallel line we're looking for will also have a slope of [tex]2/3[/tex]. Using the point-slope form of a line, we can write:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

where m is the slope and [tex](x_{1} , y_{1} )[/tex] is the given point. Substituting the values we have:

[tex]y - 3 = (2/3)(x - (-2))[/tex]

[tex]y - 3 = 2/3 x + 4/3[/tex]

[tex]y = 2/3 x + 13/3[/tex]

So the equation of the line parallel to the given line passing through the point  [tex]t (-2, 3) is y = 2/3 x + 13/3[/tex], which is option A.

To find the equation of a line perpendicular to a given line, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.

The given line has a slope of 2/3, so the perpendicular line we're looking for will have a slope of -3/2. Using the point-slope form of a line again, we can write:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

where m is the slope and  [tex](x_{1} , y_{1} )[/tex] is the given point. Substituting the values we have:

[tex]y - 3 = (-3/2)(x - (-2))[/tex]

[tex]y - 3 = -3/2 x - 9/2[/tex]

[tex]y = -3/2 x + 15/2[/tex]

Therefore,  the equation of the line perpendicular to the given line passing through the point [tex](-2, 3) is y = -3/2 x + 15/2,[/tex] which is not one of the options provided.

The following estimates were provided; MPL 20-0.4L; and APL= 20-0,2L-320/L i. Over what range of l (variable inputs) should production take place? ii. What is the range of output over the range of labour in (i) ​

Answers

Answer: To determine the range of input (L) over which production should take place, we need to find the point at which the marginal product of labor (MPL) is zero:

MPL = 20 - 0.4L

0 = 20 - 0.4L

0.4L = 20

L = 50

So production should take place for values of L less than or equal to 50.

To find the range of output over this range of labor, we can use the average product of labor (APL) equation:

APL = 20 - 0.2L - 320/L

Substituting L = 50, we get:

APL = 20 - 0.2(50) - 320/50

APL = 20 - 10 - 6.4

APL = 3.6

So the range of output over the range of labor from 0 to 50 is approximately 0 to 3.6 units of output.

Find the

-coordinates at which the tangent line to =(x−6/x)^8

is horizontal.

Answers

The coordinates at which the tangent line to f(x) = (x-6/x)^8 is horizontal are (√6, f(√6)) and (-√6, f(-√6)), where f(x) is the given function.

Coordinates calculation.

To find the coordinates at which the tangent line to the function f(x) = (x-6/x)^8 is horizontal, we need to find the critical points of the function where the derivative is zero or undefined.

First, let's find the derivative of the function:

f(x) = (x-6/x)^8

f'(x) = 8(x-6/x)^7 * (1 - (-6/x^2))

Simplifying the second term, we get:

f'(x) = 8(x-6/x)^7 * (x^2+6)/x^2

Now we need to set the derivative equal to zero and solve for x:

8(x-6/x)^7 * (x^2+6)/x^2 = 0

(x^2+6) cannot be zero, so we can ignore that factor.

8(x-6/x)^7 = 0

(x-6/x) = 0

x^2 - 6 = 0

x = ±√6

So we have two critical points at x = √6 and x = -√6.

Now we need to determine whether these critical points correspond to a maximum, minimum, or inflection point. To do this, we can use the second derivative test.

Taking the derivative of the first derivative, we get:

f''(x) = 8(x-6/x)^6 * (56/x^3 + 7)

Evaluating the second derivative at x = √6, we get:

f''(√6) = 8(√6-6/√6)^6 * (56/√6^3 + 7)

f''(√6) > 0, so the function has a local minimum at x = √6.

Evaluating the second derivative at x = -√6, we get:

f''(-√6) = 8(-√6-6/-√6)^6 * (56/-√6^3 + 7)

f''(-√6) < 0, so the function has a local maximum at x = -√6.

Therefore, the coordinates at which the tangent line to f(x) = (x-6/x)^8 is horizontal are (√6, f(√6)) and (-√6, f(-√6)), where f(x) is the given function.

Answers

Answer: Mark as brainliest

Option A shows the correct method to calculate the volume of the cylinder-shaped mold.

Step-by-step explanation:

The correct method to calculate the number of cubic units of cake batter needed to fill the mold is:

V = πr^2h

Where:

V = volume of the cake batter needed

π = 355/113 (approximate value of pi)

r = radius of the cylinder (diameter/2 = 10/2 = 5)

h = height of the cylinder (7)

Substituting the values in the formula, we get:

V = (355/113) x 5^2 x 7

V = 616.07 cubic inches (rounded to two decimal places)

Therefore, approximately 616.07 cubic inches of cake batter are needed to fill the mold.

Let x represent the number of student tickets sold and y represent the number of adult tickets sold.” I already solved the first question but I am confused on the rest please help!

Answers

Therefore, 34 student tickets and 126 adult tickets were sold.

What is Algebraic expression?

Algebraic expressiοn can be defined as cοmbinatiοn οf variables and cοnstants.

Write twο equatiοns tο mοdel the prοblem:

Let x be the number οf student tickets sοld, and y be the number οf adult tickets sοld. Then, we can write the fοllοwing twο equatiοns:

5x + 10y = 1430 (the total amount earned from ticket sales is $1430)

x + y = 160 (the total number of tickets sold is 160)

Solve for one of the variables in terms of the other:

We can rearrange the second equation to solve for one of the variables in terms of the other:

x + y = 160

x = 160 - y (subtract y from both sides)

Substitute the expression found in step 2 into one of the equations from step 1:

We can substitute the expression x = 160 - y into the first equation:

5x + 10y = 1430

5(160 - y) + 10y = 1430 (substitute x = 160 - y)

800 - 5y + 10y = 1430 (distribute the 5)

5y = 630 (combine like terms)

y = 126 (divide both sides by 5)

Solve for the other variable:

Now that we know y = 126, we can use the expression x = 160 - y to find x:

x = 160 - y

x = 160 - 126

x = 34

Therefore, 34 student tickets and 126 adult tickets were sold.

Check the solution:

We can check our solution by plugging in x = 34 and y = 126 into the original equations:

5x + 10y = 1430

5(34) + 10(126) = 1430

x + y = 160

34 + 126 = 160

Therefore, Both equations check out, so our solution is correct.

An employee at a department store is stocking cell phone cases. He has a box of 80 cases. Among the 80 cases, 40 are black, 10 are white, and 30 are pink.

If he reaches into the bag randomly and removes one at a time, what is the probability that the first three cases are all pink?

2Points

Answers

The probability that the first three cases are all pink is 0.015. In most cases, the probability is given as a ratio between the total number of outcomes in the sample space and the number of positive outcomes.

What exactly is probability in mathematics?

Probability is the potential for something to occur. The value is expressed in the range of 0 to 1 .In light of this, whenever we are unsure of how an event will turn out, we can talk about the probabilities of various outcomes, or how likely they are.

Statistics is a term that refers to the study of probability-based phenomena. Hence, the probability that an event will occur depends on both the quantity of favorable outcomes and the total number of outcomes.

Probability = no. of favorable cases/total number of cases

Given

Total No. of cases = 80

Black = 40

White = 40

Pink = 30

Probability = no. of favorable cases/total number of cases

For first draw

Pink cases = 10

Total cases = 80

P1  = 10/80

For second draw

Pink cases left = 9

Total cases = 79

P2  = 9/79

For second draw

Pink cases left = 8

Total cases = 78

P2  = 8/78

Now Total Probability is

P = P1× P2 × P3

P = 10/80 × 9/79 × 8/78 = 720/492,960

P = 3/2054 ≈ 0.015

How to get the value of x and y?

We know that the sum of two adjacent angles is always 180°, then we can write two linaer equations:

8y + 4x + 26 = 180

4y - 12 + 3x = 180

We can simplify that to get the system of equations:

4x + 8y = 154

3x + 4y = 192

To solve this, we can take the difference between twice the second equation and once the first equation to get:

2*(3x + 4y) - (4x + 8y) = 2*192 - 154

6x + 8y - 4x - 8y = 230

2x = 230

x = 230/2

x = 115

Then the value of y is:

y - x = 7 ------------------------(II)

y = 7 +x

Substitute y = 7 + x in equation (I),

Answers

Angela's friend earned a salary of $950 plus a commission of $1,599.50 for a total earnings of $2,549.50 in the month they both sold $23,800 worth of merchandise.

To find out how much Angela's friend earned in the same month, we need to first calculate their commission earnings.

Angela's commission earnings can be found by multiplying the total sales by her commission rate of 11%:

Commission earnings = $23,800 x 0.11 = $2,618

Now, let's calculate her friend's commission earnings. First, we need to subtract the salary from the total sales:

Total sales - Salary = Commissionable sales
$23,800 - $950 = $22,850

Next, we can calculate the commission earnings by multiplying the commissionable sales by the commission rate of 7%:

Commission earnings = $22,850 x 0.07 = $1,599.50

Adding the commission earnings to the salary gives us the total earnings for the month:

Total earnings = $950 + $1,599.50 = $2,549.50

Therefore, Angela's friend earned $2,549.50 for the same month.

Suppose you are the building rectangular puppy kennel for your new puppy with 25 feet of fence. The side of the kennel next to your house does not need a fence.this side is 9 feet long. Find the dimensions of the kennel.

Answers

The required dimensions of the kennel are 17 feet by 8.5 feet.

How to find the dimensions?

Let the length of the kennel be L and the width be W.

We know that the total length of fence available is 25 feet. Since one side of length 9 feet does not need fencing, the total length of the other three sides that need fencing is (L + 2W - 9).

Therefore, we have:

25 = L + 2W - 9

Simplifying the equation, we get:

L + 2W = 34

We also know that the area of the kennel is given by:

Area = Length x Width

Substituting L = 34 - 2W from the first equation into the above equation, we get:

Area = (34 - 2W) x W

Simplifying the equation, we get:

Area = 34W - 2W²

To maximize the area, we differentiate the above equation with respect to W, set it equal to zero, and solve for W:

d(Area)/dW = 34 - 4W = 0

Solving for W, we get:

W = 8.5

Substituting this value of W back into the equation L + 2W = 34, we get:

L + 2(8.5) = 34

L + 17 = 34

L = 17

Therefore, the dimensions of the kennel are 17 feet by 8.5 feet.

If OS is a radius perpendicular to chord WV and intercepts it at point M. Find MW.

Answers

Answer:

o find MW, we need to use the fact that OS is perpendicular to WV, which means that OS is also perpendicular to MW since it bisects WV.

Let's label the midpoint of WV as point N. Then we can use the Pythagorean theorem to find MW.

First, we need to find the length of ON. Since OS is a radius of the circle, it is equal to the radius of the circle, which we can call r. Then, using the Pythagorean theorem, we have:

ON^2 = OS^2 - SN^2

ON^2 = r^2 - (WV/2)^2

ON^2 = r^2 - (MW/2)^2 (since NW = MV)

Next, we need to find the length of MN. We know that OM is half of WV, so OM = WV/2. Then, using the Pythagorean theorem again, we have:

MN^2 = ON^2 + OM^2

MN^2 = r^2 - (MW/2)^2 + (WV/2)^2

MN^2 = r^2 - (MW/2)^2 + (2MW/2)^2 (since WV = 2MW)

MN^2 = r^2 - (MW/2)^2 + MW^2

Finally, we can solve for MW by using the Pythagorean theorem one more time:

MW^2 = MN^2 + NW^2

MW^2 = (r^2 - (MW/2)^2 + MW^2) + (MW/2)^2

MW^2 = r^2 - (MW/2)^2 + MW^2/4 + MW^2/4

MW^2 = r^2 - (MW/2)^2 + MW^2/2

Multiplying both sides by 4 gives:

4MW^2 = 4r^2 - MW^2 + 2MW^2

3MW^2 = 4r^2

MW^2 = 4r^2/3

MW = 2r/sqrt(3)

Therefore, the length of MW is 2r/sqrt(3).

An airplane flying into a headwind travels the 1560-mile flying distance between two cities in 3 hours. On the return flight, the airplane travels this distance in 2 hours and 30 minutes. Find the airspeed of the plane (in mi/h) and the speed of the wind (in mi/h), assuming that both remain constant.
airspeed mi/h
wind speed mi/h

Answers

So the speed of the wind is 52 miles per hour. When the airplane is flying into a headwind, its ground speed (the speed at which it appears to be moving relative to the ground)

what is speed  ?

In physics, speed is the rate at which an object moves, or the distance traveled per unit of time. It is a scalar quantity, meaning that it has magnitude (a numerical value) but no direction.

In the given question,

Let's use "s" to represent the airspeed of the plane, and "w" to represent the speed of the wind.

When the airplane is flying into a headwind, its ground speed (the speed at which it appears to be moving relative to the ground) is s - w. We know that the airplane travels 1560 miles in 3 hours, so we can set up the equation

1560 = (s - w) * 3

Simplifying this equation, we get:

s - w = 520

When the airplane is flying with a tailwind (i.e., in the opposite direction of the headwind), its ground speed is s + w. We know that the airplane travels 1560 miles in 2.5 hours (since 2 hours and 30 minutes is equal to 2.5 hours), so we can set up the equation:

1560 = (s + w) * 2.5

Simplifying this equation, we get:

s + w = 624

Now we have two equations:

s - w = 520

s + w = 624

We can solve this system of equations by adding them together. When we add the left sides of the equations, we get:

2s = 1144

Dividing both sides by 2, we get:

s = 572

So the airspeed of the plane is 572 miles per hour.

Now we can use one of the equations we found earlier to solve for the wind speed. Let's use the equation:

s - w = 520

Substituting s = 572, we get:

572 - w = 520

Simplifying this equation, we get:

w = 52

So the speed of the wind is 52 miles per hour.

Answers

Answer:

Step-by-step explanation:

In the given figure, we have three circles arranged such that they touch each other. Let the centers of these circles be A, B, and C, with radii 5.4, 4.4, and 3.4, respectively.

We can see that triangle ABC is an equilateral triangle, since all sides are of equal length (the radii of the circles).

To find the angle A, we can use the law of cosines, which states that:

c^2 = a^2 + b^2 - 2ab cos(C)

where a, b, and c are the lengths of the sides of a triangle, and C is the angle opposite the side of length c.

Since triangle ABC is equilateral, we have a = b = c, and C = 60°. Therefore, we can rewrite the above equation as:

c^2 = 2a^2 - 2a^2 cos(60°)

Simplifying and solving for a, we get:

a = c / sqrt(3)

Substituting the given values, we have:

a = 4.4 / sqrt(3) ≈ 2.54

Therefore, angle A is:

A = 180° - 60° - 60° = 60°

And angle B is:

B = 180° - A = 120°

Finally, we can use the law of sines to find the length of side c:

sin(A) / a = sin(B) / b = sin(C) / c

Substituting the values we have found, we get:

sin(60°) / 2.54 = sin(120°) / c

Simplifying and solving for c, we get:

c = 2.54 / sqrt(3) / sin(120°) ≈ 3.71

Therefore, the length of side c is approximately 3.71, and angle B is 120°.

Use the graph that shows the solution to f(x)=g(x). f(x)=x2 g(x)=(12)x−1 What is the solution to f(x)=g(x)?
x=−1
x = 0
x = 1
x = 2

Answers

Answer:

To find the solution to f(x)=g(x), we need to find the point(s) where the two curves intersect.

The graph is not provided, but we can find the solution algebraically by setting the two functions equal to each other:

f(x) = g(x)

x^2 = 12^(x-1)

To solve for x, we can take the logarithm of both sides:

log(x^2) = log(12^(x-1))

2log(x) = (x-1)log(12)

2log(x) = xlog(12) - log(12)

2log(x) - xlog(12) = -log(12)

log(x^2) - log(12^x) = -log(12)

log(x^2/12^x) = -log(12)

log(x/12) = -log(12)

log(x) - log(12) = -log(12)

log(x) = 0

x = 1

Therefore, the solution to f(x)=g(x) is x=1.

In the model the height of the climbing frame is 10 cm what is the actual height of the frame?

Answers

To determine the actual height of the climbing frame, we need to know the scale factor of the model. If the scale factor is, for example, 1:50, it means that every 1 cm on the model represents 50 cm in real life.

Assuming that we have the scale factor, we can use the following proportion:

model height / actual height = scale factor

We know that the model height is 10 cm, and we want to find the actual height. Let's say the scale factor is 1:100. Then we have:

10 cm / actual height = 1/100

Multiplying both sides by the actual height, we get:

actual height = (10 cm) x (100/1) = 1000 cm

Therefore, the actual height of the climbing frame in this example is 1000 cm, or 10 meters.

A). The function is symmetric about the line x = 1 and continuous.

For 0 x 2, the function is positive. The highest value for the function is

(1, 1). The value of f(x) increases as x approaches positive infinity.

Describe function?

Each input value is given a distinct output value by a rule known as a function.

Functions can be shown using graphs, tables, mathematical notation, and other techniques.

The function is positive in the range 0 x 2, therefore we can limit the curve to that region. As a result, the curve may increase quickly as x moves away from 2. The produced graph might look like this:  

B). The function is continuous and symmetrical about the line x = 2. For the function, the bare minimum is (2, 3). As x approaches positive or negative infinity, f(x) approaches infinity.

Similar to how we can design a symmetric curve with a minimum point at x = 2 because the function is symmetric around that value. (2, 3). When x gets close to positive or negative infinity, the function moves towards infinity.

One function, f(x), is defined as f(x) = (x + 4)2 - 3. A second function, g(x), is a parabola that passes through the points shown in the table below. What is the absolute value of the difference between the y-intercepts of f(x) and g(x)? 17 15 9 6

Answers

According to the given information, the absolute value of the difference between the y-intercepts of f(x) and g(x) is 0.

What is a function?

A function is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output.

To find the y-intercept of a function, we set x=0 and evaluate the function at that value.

For the function f(x) = (x + 4)2 - 3, we have:

f(0) = (0 + 4)2 - 3 = 13.

To find the y-intercept of the function g(x), we can use the given points and try to write it in the form y = ax² + bx + c, where a, b, and c are constants.

Using the given points, we can write three equations:

When x = -2, y = 17: 17 = 4a - 2b + c

When x = -1, y = 15: 15 = a - b + c

When x = 1, y = 9: 9 = a + b + c

Solving this system of equations, we get a = -1, b = 1, and c = 13. Therefore, the equation of the function g(x) is:

g(x) = -x² + x + 13.

To find the absolute value of the difference between the y-intercepts of f(x) and g(x), we can subtract the two y-intercepts and take the absolute value:

|f(0) - g(0)| = |13 - 13| = 0.

Therefore, the absolute value of the difference between the y-intercepts of f(x) and g(x) is 0.
