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:
Coefficient 
Step-by-step explanation:
These numbers are the ones in front of the variables in the beginning of an equation also known as coefficients. The numbers all by themselves without variables are constants. The first term is usually the number with the biggest exponent.
 
        
             
        
        
        
For this problem, let's assign variable x to the value of the actual weight. The recommended weight is the central value of the range. So, the variation must be 20 grams below and above the recommended weight. The equation would be:
Actual weight = |Recommended weight +/- 20|
x = |430 +/- 20|
