Arocket is shot into the air with an initial velocity of 800m/sec. the equation h(t) = -16t squared + 1440t models the height of the ball. how long does it take for the rocket to hit the ground?

where is the option given

answer: the answer is   graph (a)

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
