Answer: ok
Step-by-step explanation:
11) 75 percent. this is bc 32 - 8 is 24, and 24 of 32 as a percentage is 75 percent.
12) 25 percent, bc 15 percent of 60 is 25 percent
So you want height to be 0 so you plug zero into the height and solve from there. You subtract 192 from both sides to get -192=-16tsquared. Then you would divide by -16 and end up with 12 = t^2. Then you find the square root of 12 and get t = 3.464 seconds.
