Question

h(t) = –16t2 + 80t

Answer 1

what do u want to do with it?

Answer 2

figure it out this is the whole question .... A ball was kicked straight up into the air from at a velocity of 80 feet per second. The function h(t) = –16t2 + 80t models the height of the ball t seconds after it was kicked. For how many seconds is the ball descending?

Answer 3

first make h(t) = 0
16t^2 - 80t = 0
16t(t - 5) = 0

t = 0 or 5 secs

5 seconds is the time for the entire flight.

Answer 4

ascending time = descending time

so time descending = 2.5 secs

Answer 5

Suppose the equation h(t) = –t2 + 5t + 14 models the height of a ball thrown into the air off the bleachers. Which statement about the flight of the ball is true?

Answer 6

Hampton Furniture produces couches in its factory. The quadratic function, p(n) = –15n2 + 615n – 600, can be used to determine the company’s weekly profit where n is the number of couches made. What is the largest number of couches the factory can produce in 1 week and still make a profit?
