The time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds
Given the equation representing the height reached by a rocket as:

The rocket will hit the ground when y = 0. Substituting y = 0 into the expression to get x;

On factorizing:
x = 10.43 seconds
Hence the time that rocket will hit the ground, to the nearest 100th of second is 10.43 seconds

Answer:
hiii
Step-by-step explanation:
1. Multiply both sides by 3
38/3x x 3 +16/3. x =-20x3
2. Simplfy
38x+16=-60
3. Subtract 16 from both sides
38x+16-16=-60-16
4. Simplfy
38x=-76
5. Divide both sides by 38
38x/38=-76/38
6. Simplfy
x=-2
