1. () = 7 7 5 5 + 4 4 2 2 find (4) (1).

2. A population grows from an initial size of 100,000, according to the law of () = 100,000(1 + 0.2 + 2 ) where x is the number of years. Find the acceleration in the size of the population.

3. A potato is launched vertically upward with an initial velocity of 100ft/s from a potato gun at the top of an 85-foot-tall building. The distance in feet that the potato travels after t seconds is given by () = 16 2 + 100 + 85.

a) Find the velocity of the potato after 0.5 s and 2.5 s.

b) Find the acceleration of the potato at 0.5 s and 2.5 s.

I really need the help with these 3 problems. Thank you
