Answer: Bottom-Right corner
The points are (-5,6) (-5,-6) (4,-6)

-----------------------------------------

Explanation:

What you do is go through each of the answer choices, plot the points, and see which give you a right triangle. A right triangle has one 90 degree angle. 

The upper-left choice leads to an obtuse triangle, so we can cross that off the list. It turns out that the other choices lead to right triangles.

The upper-right choice has a hypotenuse of roughly 11.18, so that's also eliminated

The bottom-left choice has a hypotenuse of 10.82, which means we cross that off the list

The bottom-right choice has a hypotenuse of 15, so we found the answer

Note: you use the distance formula to find the length of the hypotenuse. The distance formula is
d = sqrt((x1-x2)^2+(y1-y2)^2)

What does the equation inverse of the function found in part b represent in the contract of the problem ? explain your answer .
gavmur [86]

Answer:

f^{-1}(x) =\frac{x}{3} - 5

The inverse function is to calculate the number of rides; given the amount paid

Step-by-step explanation:

Given

Admission = 15

Ride = 3 per ride

Required

Explain the inverse function

First, we calculate the function

Let x represents the number of rides

So:

f(x) = Admission + Ride * x

f(x) = 15 + 3 * x

f(x) = 15 + 3x

For the inverse function, we have:

y = 15 + 3x

Swap x and y

x = 15 + 3y

Make 3y the subject

3y = x - 15

Make y the subject

y =\frac{x}{3} - 5

Replace y with the inverse function

f^{-1}(x) =\frac{x}{3} - 5

The above is to calculate the number of rides; given the amount paid
