Answer:
10a + 7
Step-by-step explanation:
This problem is asking you to plug in 2a + 3 for x.
g(x) = 5x - 8
g(2a + 3) = 5(2a + 3) - 8 = 10a + 15 - 8 = 10a + 7
you multiply the previous term by 3 each time
Answer:
X=62
Step-by-step explanation:
solve half of it like 90 degrees +22 degrees. then minus from 180 degrees
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.
