H=-16t² +v(0)t+h(0)
v(0)=192
h=-16t² +192t+h(0)
 h(0) should be  0, because the mortar sits on the ground.
h= - 16t²+192t
This function will have maximum because it has minus  before x², and parabola is looking down.

h=-(16t²-192t)=-(16t² -2*4t*24+24²)+24²
h=-(4t-24)²+24²
h=-(4t-24)²+576 
vertex (24 feet, 576 feet)
24 feet horizontally from the mortar and 576 feet up

What is the total interest earned in two years on an account containing $500 at 3.5% interest, compounded annually?
Andrei [34K]

Answer: $35.6125

Step-by-step explanation:

3.5% = 0.035

Let's find the deposit amount with interest at the end of the first year:

500 + 500 · 0.035 = 517.5

Let's find the amount of the deposit with interest at the end of the second year:

517.5 + 517.5  · 0.035 = 535.6125

Find the total interest earned over two years:

535.6125 - 500 = 35.6125
