3 ( 14-8) =18
B= 14
I subtracted 14-8 and i got 6, then I multiplied 3 times 6 and got 18. Therefore, 14 is a valid answer.
Answer:
The maximun height that the rocket will reach is 3150 ft.
Step-by-step explanation:
This problem requieres that we maximize the function. For this we need the function to be of the form:
We already have that covered, as the height of the rocket is represented by:
We start calculating the derivative of h(t), wich is:
We need to remember that the derivative of a function represents the slope of said function at a given point. The maximum value of the function will have a slope equal to zero.
So we find the value in wich the derivative equals zero:
This means that 15 seconds is the time at wich the rocket will reach it's maximum height.
We replace this value in the original equation to solve the problem:
With this we can conclude that the maximum height the rocket will reach is 3150 ft.
I thinks it is c because its not 100% made from silver
