If an average-sized man with a parachute jumps from an airplane, he will fall 12.5(0.2^t - 1) + 19t feet in t seconds. How long will it take him to fall 134 feet? (Round your answer to two decimal places.)

The answer would be a i think

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
