B. To stay in orbit a rocket must reach about 8km/sec. Use your equation R=e^(v+.0098t/c) to find R the ratio of full to empty weight of the rocket if:
v=8km/s t=100s c=2.8km/sec

answer: the correct one is a

step-by-step explanation:

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=
