The function h(t) = -16t² + 72t will equal zero when the ball hits the ground:

-16t² + 72t = 0. Solving for the time, t, we factor -16t² + 72t : 16t (-t + 4.5) = 0.

This results in t = 0 and t = 4.5 sec. The ball hits the ground after 4.5 sec.

Problem 12.

Starting with A:(-5,3): Reflecting A over the y-axis results in B: (5,3). Translating B 3 units to the right results in C: (8,3). Finally, translating C down by 4 units results in D: (8,-1) (answer).

If a person uses $700 in credit with an interest of 14%,what is that person going to owe after three billing cycles with simple
Brums [2.3K]
Simple interest:  i = p*r*t, where r is the annual interest rate and t is the number of years.
                                14%
This boils down to ----------- interest per month:  a monthly rate of 0.0117.
                                12 mo

Thus, after 3 months, the amount owed, including the original $700, would be $700 + 3($700)(0.0117) = $724.57.
