The answer is 36.
Because 20% of 36 is equal to 7.2
And 36 - 7.2 = 28.80
Answer: 350km/h,349
Step-by-step explanation:Find the exact value using tringometric identities
I guess the original function was
y = 5x (1)
y+Δy =5(x+Δx) (2)
(2) - (1) =
Δy = 5Δx
Δx →0, Δy/Δx →5
For this case we have the following function:
To find the maximum of the function, what we should do is to derive the equation.
We have then:
We match zero:
We clear the value of x:
We substitute the value of x in the function to find the maximum:
Rewriting:
Answer:
a formula in terms of a for the maximum of f (x) is:
