Answer:
48
Step-by-step explanation:
all you do is 64 times 3/4
Let y = f(x)
Let cr = cube root for short
y = cr{3x} + 2
Switch x and y.
x = cr{3y} + 2
Solve for y.
x - 2 = cr{3y}
Raise both sides to the 3rd power.
(x - 2)^3 = [cr{3y}]^3
(x - 2)^3 = 3y
[(x - 2)^3]/3 = y
Replace y with the inverse function notation
f^(-1) x.
f^(-1) x = [(x - 2)^3]/3
Choice b is the answer.
I think the answer to this question is b
Answer:
147
Step-by-step explanation:
The ∑ symbol means sum the term inside 4n + 1 from n = 2 to n = 8
Substitute n = 2, 3, 4, 5, 6, 7, 8 into the expression and sum the results , that is
4(2) + 1 + 4(3) + 1 + 4(4) + 1 + 4(5) + 1 + 4(6) + 1 + 4(7) + 1 + 4(8) + 1
= 9 + 13 + 17 + 21 + 25 + 29 + 33
= 147
