Answer:
A. y = 3x/4
Step-by-step explanation:
a proportional relationship between x and y is a straight line passing through the origin (0, 0).
The equation must be in the form y = kx.
y = 3x/4
y = 3/4x
Answer:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
Step-by-step explanation:
For this case we have the function of the height in terms of the time givenby:

And we want to known when the rockect hit the ground and for this case we need to solve the equation 

And as we can see we have a quadratic equation like this one:

Where: 
And the general solutions are given by:

If we replace the values that we have we got:


And since the time can't be negative we have that:

So the answer for this case would be after 10.36 seconds the rocket will hit the ground
