If f(x)= 3x-9 and g(x)= x^2, what is (g0f)(5)

1 answer:

6 0

We are asked to find z = g0f or what is the same:
z = g (f (x))
That is, we must introduce the function f (x) within the function g (x)
So, we have
f (x) = 3x-9
g (x) = x ²
Therefore we have the following function
z = (3x-9) ²
Finally (g0f) (5) = (3 (5) -9) ²
(g0f) (5) = 36

I think it is b because probability of 2 is 1/6 then probability of 4 is 1/6. If you times them together 1/6x1/6 it will equal 1/36 so b

Answer:

D.) $5.19$ × $10^{-5}$

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the

10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Since we moved to right 5 places, the exponent is -5.

Just multiply the number out of the parentheses with the ones inside. So -8 times 9=-72 and 3q times -8=-24q. Now keep the same operation, which is subtraction in this case.So, -72--24q or -72+24q will be the correct answer.
