An object dropped from a height of 600 feet has a height, h(t), in feet after t seconds have elapsed, such that h(t)=600−16t2. express t as a function of height h, and find the time to reach a height of 250 feet.

The function t(h) is t(h) =

The time to reach a height 250 feet is 4.68 seconds

Step-by-step explanation:

* Lets explain how to solve this problem

- An object dropped from a height of 600 feet has a height, h(t), in feet

  after t seconds have elapsed, such that

  h(t) = 600 − 16 t²

- We need to express t is a function of the height h

- To do that lets find t in terms of h

∵ h = 600 - 16 t²

- Add 16 t² to both sides

∴ 16 t² + h = 600

- Subtract h from both sides

∴ 16 t² = 600 - h

- Divide both sides by 16

∴ t² =

- Take √ for both sides

∴ t =

∴ t(h) =

* The function t(h) is t(h) =

- Now lets find the time of the object to reach a height 250 feet

∵ t(h) =

∵ h = 250

∴ t(250) =

∴ t(250) = 4.68 seconds

* The time to reach a height 250 feet is 4.68 seconds

c. 4 and 1/2 pounds is the answer! : )

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
