Below is the question, it requires that you use 3.14 for pi. A spherical helium balloon that is 8 feet in diameter can lift about 18 pounds. What does the diameter of a balloon need to be to lift a person who weighs 144 pounds?

29 is the correct answer

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
