A cannon ball is shot from a cannon with an upward velocity of 40 feet per second. The equation that gives height h, in feet, of the ball at time t, in seconds h(t) = -16t^2 + 40t + 1.5 a. What is the height of the ball after 2 seconds?
b. What is the maximum height reached by the ball?
c. When does the ball meet its maximum height?
d. How long will it take before the ball hits the ground?

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
