2) If a projectile is fired straight upward form the ground with an initial speed of 96 feet per second, then its height h in feet after t seconds is given by the function h(t)= -16t^2+96t
Find the maximum height of the projectile.

3) he model A= 1.6 e^0.039t gives the minimum wage, A, in year t, and where t= 0 represents the year 1970.
a)Use model to predict the minimum wage in the year 2018.
b) Use the model to find the year in which the minimum wage reach $15 per hour.
