4 feet since the shadows are half the size of the original object
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
Answer:
that should be how you would solve those questions..
9 - 6 = 3
so 3 + 6 = 9 which is an addition equation that helps you find the answer.
