Suppose f(x) = ----------
                          sqrt(x) 
                                                                                                   8
What if we let x = 16 (just an example)?  We'd get f(16) = ------------- = 2.
                                                                                              sqrt(16)

What if we let x = g(x) = 2x+4?

We'd get the following:

                     8
f(g(x)) = -------------- = y
              sqrt(2x+4)

So...the correct answer is the fourth one.

Find two positive numbers satisfying the given requirements.
Umnica [9.8K]

Answer:

8 and 19

Step-by-step explanation:

To some this, let's first list all the factors of 152. They are;

1, 2, 4, 8, 19, 38, 76, 152.

Now, let's arrange them to reflect being multiplied to get 152.

Thus;

1 × 152 = 152

2 × 76 = 152

4 × 38 = 152

8 × 19 = 152

Also, let's do the same for their sum;

1 + 152 = 153

2 + 76 = 78

4 + 38 = 42

8 + 19 = 27

Looking at the figures above, the ones that their product is 152 but have the least sum are 8 and 19
