Part 1: 1/2; Part 2: 8

Question 5

Which statement best describes the function h(t) = 210 – 15t?

Revolt · Accepted Answer

h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.

Question 6

A hot air balloon descends to the ground. The function h(t) = 210 – 15t can be used to describe the altitude of the balloon as it approaches the ground. Which statement best describes the graph of the function that models the descent of the balloon?

Revolt · Accepted Answer

The graph is continuous because there can be fractional values for time.

Question 7

What is the domain of the function represented in the graph?

Revolt · Accepted Answer

{t| 0 ≤ t ≤ 14}

Question 8

Consider the function represented by the equation 6c = 2p – 10. Write the equation in function notation, where c is the independent variable.

Revolt · Accepted Answer

f(c) = 3c + 5

Question 9

Marlene rides her bike at a rate of 16 miles per hour. The time in hours that she rides is represented by the variable t, and the distance she rides is represented by the variable d. This relationship is modeled with distance d as a function of time t. Which statements are true of the scenario? Select two answers..

Revolt · Accepted Answer

The distance traveled depends on the amount of time Marlene rides her bike.; The function f(t) = 16t represents the scenario.
