Question 6

A professor uses a video camera to record the motion of an object falling from a height of 250 meters. The function f(x) = –5x2 + 250 can be used to represent the approximate height of the object off the ground after x seconds. Which is the best estimate for the amount of time elapsed when the object is 120 meters off the ground?

Revolt · Accepted Answer

5 seconds

Question 7

Which statements are true? Check all that apply.

Revolt · Accepted Answer

The function that best represents the data is f(x) = 24,512(0.755)x.; The function decreases indefinitely.; It is reasonable to interpolate to the value of the car at 4.5 years.

Revolt · Accepted Answer

Part 1: 10,346.0; Part 2: 1.1; Part 3: 112,096

Question 9

What values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x) = x2 + x + 0 Based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds? feet

Revolt · Accepted Answer

-16; 81; 19
