4^4 * 4^(-9) = 4^(4-9) = 4^(-5) or 1/(4^5)
7) Skateboarding down a hill or a ramp. Rolling a ball on the floor. Going up and down the ramp of a moving truck.
8) Throwing a ball into the air and then catching it. Skateboarding a half-pipe. Shooting a basketball. Hitting a baseball.
Population are always modeled by exponential growth equation given by:
f(x)=a(1+b)^t
where:
a=original number
b=rate of growth
t=time
thus
f(x)=412(1.05)^t
the population after 9 months will be:
f(9)=412(1.05)^9=639.15=639
