Answer:

(g o f)(x) = \sqrt{-510} (not simplified)

Step-by-step explanation:

(g o f)(x) = g(f(x))

g(x) = \sqrt{3x}  f(x) = x^{3} + 9x

g(f(-5)) = g((-5)^{3} + 9(-5) = (-125) + (-45) = -170

g(-170) = \sqrt{3(-170)} = \sqrt{-510}

PLEASE HELP ME THIS.. I REALLY NEED<br> HELP

Answer:

  5 hours

Step-by-step explanation:

A quick way to look at this is to compare the difference in hourly charge to the difference in 0-hour charge.

The first day, the charge is $3 more than $12 per hour.

The second day, the charge is $12 less than $15 per hour.

The difference in 0-hour charges is 3 -(-12) = 15. The difference in per-hour charges is 15 -12 = 3. The ratio of these is ...

  $15/($3/h) = 5 h

The charges are the same after 5 hours.

__

If you write equations for the charges, they will look like ...

  y1 = 15 + 12(x -1)

  y2 = 3 + 15(x -1)

Equating these charges, we have ...

  15 +12(x -1) = 3 + 15(x -1)

  12x +3 = 15x -12 . . . . . . . . eliminate parentheses

  15 = 3x . . . . . . . . . . add 12-12x

  x = 15/3 = 5 . . . . . . divide by 3

You might notice that the math here is very similar to that described in words, above.

The charges are the same after 5 hours.
