Answer:
18.56
Step-by-step explanation:
The extreme values of the function f(x) = x - 4sqrt(x) occur at the values of x for which f'(x) = 0
f'(x) = 1 - 2/sqrt(x) = 0
sqrt(x) - 2 = 0
sqrt(x) = 2
x = 4
To check for minimum or maximum,
f''(x) = 1/(sqrt(x))^3 = 1/(sqrt(4))^3 = 1/(2^3) = 1/8 => the point is a minimum.
Therefore, the minimum value = f(4) = 4 - 4sqrt(4) = 4 - 4(2) = 4 - 8 = -4 and occurs at x = 4.
Ur lines are parallel...they never intersect...means there is no solution...
ur answer { } or empty set

A ≈ 172.05
Step-by-step explanation:
i used the google calculator
just search up "area of a pentagon" and google has their own calculator as the first option.
Wait it says ur in high school so u can't be over 30. that isn't possible. So what's the problem here? not good at math.
