Answer:

22 seconds

Step-by-step explanation:

h(t) = -16t2 + 704t

The maximum will occur at the axis of symmetry.

We can find the axis of symmetry at

h = -b/2a

where at^2 +bt+c

 so a = -16 and b = 704

h = -704/(2*-16)

h= -704/-32

  = 22

Answer:

6

Step-by-step explanation:


#1: 4x - 8 = 16 (You want to remove -8)

#2: 4x = 24 (In order to remove -8 you need to cancel it out, add 8 to -8, also add 8 to 16)

#3: 4x = 24 (Now you need to get the x by itself, divide 4x by 4 to only get x and also divide 24 by 4)

#4: x = 6

Rule of Thumb: If you do something to one side, to it to the other :)
