Answer:
9
Step-by-step explanation:
Just substitute the value of x onto the x variables in the equation
; 4(1)^2 + 5(1)
; 4 + 5
; 9
Step-by-step explanation:
The line equation is y = 4x.
Answer: 120 seconds
Step-by-step explanation: In order to find the maximum value of a function, you can take the derivative of the function and equalize the result to 0.
f'(x)=(-3x^2 + 12x)'=-6x+12=0
x=2
When x is 2, the function will reach its maximum value.
f(2)=-3(2)^2 + 12.2 = -12 + 24 = 12
The maximum value (f(x)) is equal to 12 and the time passed is 2 minutes which is equal to 120 seconds.
