H(t) = -16t^2 + 64t I need to find the maximum height, the amount of time it took to reach that height, and the amount of time it was in the air. Can anyone help me?

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
