Answer:
a) 40 hours
b) 60 hours
C) 100 hours
Step-by-step explanation:
0.2a + 0.3b+0.5c = 76
Hence: 0.2* (0.2 λ) +0.3*(0.3 λ )+0.5*(0.5 λ ) = 76
0.38 λ =76
λ = 76/0.38 =200
Thus : 40, 60, 100

Answer:
A. f^-1(x) = x³ -12
Step-by-step explanation:
The inverse function can be found by solving ...
x = f(y)
x = ∛(y +12) . . . . . use the definition of f(x)
x³ = y +12 . . . . . . . cube both sides to eliminate the radical
x³ -12 = y . . . . . . . add -12 to isolate the y-variable
f^-1(x) = x³ -12 . . . matches choice A
I believe the answer is 7
