If f(x) = 2x - 2 and g(x) = x}, what is (gºf)(4)?

Bad White [126]

Answer:

We conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

Step-by-step explanation:

Given

$f(x) = 2x - 2$

$g(x) = x$

We have to determine (gºf)(4).

(gºf)(4) = g(f(4))

f(4) = 2(4)-2

= 8 - 2

= 6

Thus,

(gºf)(4) = g(f(4)) = g(6) = 6

Therefore, we conclude that:

(gºf)(4) = g(f(4)) = g(6) = 6

podryga [215]

Answer:

When $a=\frac{1}{4}$ and $b=6$ :

$-8ab=-12$

Step-by-step explanation:

-8ab can be seen as -8×a×b. Insert the given values:

$-8*\frac{1}{4} *6$

Simplify multiplication from left to right:

$-8*\frac{1}{4} \\\\\frac{-8}{1} *\frac{1}{4} =\frac{-8}{4} =-2$

Insert and solve:

$-2*6=-12$

What is minimal completion time for the activities in the graph below? In a complete sentence, explain how you got your answer

kupik [55]

The minimal completion time for the activities is the shortest possible time for all the activities to be finished. In doing this, we look at the path that would require the greatest amount of time. At the START node, we choose the path that would take the longest which is 7 days leading to ACTIVITY D. Next, we choose the path leading to ACTIVITY B which takes 5 days. Then, we move to ACTIVITY C taking 5 days and finally, reach the END which would take 6 days. So, the minimal completion time is:
7 + 5 + 5 + 6 = 23 days
