Answer:
25 seconds
Step-by-step explanation:
Skydiving.
height (in feet) above the earth=h(t)= -16t^2 + 10,000
the time it would take to fall when h is 0
-16t^2 + 10,000=0
-16t^2=-10000
16t^2=10000
t^2=10000/16=625
t=sqrt 625=25 seconds
5 35/36, solving steps attached below
Length of one edge is 10cm
And the surface area is 600cm2
I’m not sure but is it C?
Answer:
64
Step-by-step explanation:

3x = 192
x = 192/3
x = 64
