skydiver as a function of time?
1. h(t) = -16t2 + 200t

2. h(t) = t2 + 199

3. h(t) = -16(t - 3) + 200

4. h(t) = -16t2 + 200

Answer:

Katie,

Once the skydiver reaches terminal velocity, then he will be falling with constant speed. The distance he falls in time t will then be d = (160 ft/s)·t. And his altitude above the ground (height h) will be his altitude when the parachute opened minus the distance he has fallen so we can write:

h = (3200 ft) - (160 ft/s)·t

As a point of interest, the time it will take him to fall all the way to the ground is t = (3200 ft)/(160 ft/s) = 20 s

The statue of liberty is 305 feet tall from the base to the torch. The statue itself is 111 feet tall. How many feet tall is the
mr Goodwill [35]
Base height + statue height = total height

Total height = 305
statue height = 111

base height + 111 = 305
Subtract both sides by 111
base height = 194

The height of the base is 194 feet.

Have an awesome day! :)

How many pieces will be left over, if any, after Laurie gives her friends the candy?
My Answer:
If Laurie has four bags with ten pieces in each bag, and if her father gives her five more pieces,  she would have forty-five pieces and if she has six friends and wants to share it equally with six friends. Each friend would get 7 pieces.
