Answer:
0.54723 divided by 2 = 0.273615
Step-by-step explanation:
0.54723/2 = 0.273615
There is not much to show regarding steps, but this might help:
Dividing something by 2 means spliting the original value in half. This means that the product of the number of the original value that was divided by two is half of the orginial value. This means that <u>0.273615 + 0.273615 = 0.54723(the original value)</u> because two halves make a whole.
Please try to follow me, as I demonstrate a method of solution.
This could get complicated. I'll try to go slowly, and you must
stop me if I do anything that's not clear.

You said that -5c/8 = 20
Multiply each side by 8: -5c = 160
Divide each side by 5 : - c = 32
Multiply each side by -1 : c = -32
Answer:
1.-t₁ = 0,625 s
2.-h(max) = 6,25 f
3.-t = 1,25 s
Step-by-step explanation:
V₀ = 20 f/s
h(t) = - 16*t² + 20*t
h(max) = ??
h´(t) = - 32*t + 20
h(max) will occurs when V = 0 dh/dt = 0 then
- 32*t + 20 = 0
- 32*t = -20
t = 20/32
t₁ = 0,625 s
h(max) = h(0,625) = - 16*(0,625)² + 20*0,625
h(max) = - 6,25 + 12,5
h(max) = 6,25 f
c) The ball will hit the ground
t = 2*t₁
t = 2*0,625
t = 1,25 s
