A ball is thrown downward from the top of a 120-foot building with an initial velocity of 12 feet per second. The
height of the ball h in feet after t seconds is given by the equation h = - 16t- 12t + 120. How long after the ball
is thrown will it strike the ground?
120 ft

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

f(x)=2/3x-8, which give g(x) the greatest value.
