Callie bought 2 gallons of juice for $2.58 per gallon. She sold the juice in 1-cup servings for $0.75 each. Each serving is 1/16
konstantin123 [22]

2 gallons * 16 cups = 32 total servings
32 cups * $0.75 per cup = $24 gross revenue (total income)
$24 - $5.16 = $19.84 net revenue (profit)

Given:<br> f(x)=x^2<br> g(x)=x-1<br> Find f(g(2))+g(f(-1))
Marina CMI [18]

Answer:

-1

Step-by-step explanation:

First, we need to work out the left-hand side.

  • find g(2) → g(2) = 2 - 1 which is 1
  • next, find f(1) → f(1) = 1³ which is 1

Now, we can work out the right hand side.

  • find f(-1) → f(-1) = -1³ which is -1
  • then, find g(-1) → g(-1) = -1 - 1 = -2

Finally we can work out the full sum: 1 + -2 = -1.

Hope this helps!

Answer:

  • c = 2
  • segments 10, 8, 6 (top down)

Step-by-step explanation:

The sum of top and bottom bases is twice the midsegment.

  (c² +6) +(c² +2) = 2(4c)

  2c² -8c +8 = 0 . . . . . . . . . subtract 8c

  2(c -2)² = 0 . . . . . . . . factor

  c = 2 . . . . . . the value that makes the binomial be zero

The value of c is 2; the segment lengths (top-down) are 10, 8, 6.
