There is 3.28084 feet in a meter
(4*a)*2
lets give a a number: a = 3 so (4*3)*2 = 12*2 = 24
lets try the options:
A) 4 *(3*2) = 4*6 = 24 = the same
B) 4*2*3*2 = 8*3*2 = 24*2 = 48 = different
C) 8*3 = 24 = same
D) 4*2+3*2 = 8 +6 = 14 = different
E) 2*(4*3) = 2*12 = 24 = same
so A, C & E would be the equivalent.
Answer:
i can't see it it's turned sideways, sorry!!!!!
Step-by-step explanation:
1.
Height h = 240 feet
We insert it into formula.

Now we solve this for t:

We have two answers as the rocket will pass this height on it's way up and down.
2.
Height h = 0 feet
We insert it into formula.

Now we solve this for t:

We do not consider solution -1 as the time can not be negative. Our solution is 5s.
3.
Height at bottom of hill h = 0 feet
We insert it into formula.
