The decorating committee for a school

Mathematics
1 answer:
Schach [20]3 years ago
5 0

Answer:

D. 160

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

In this question:

For each 3 white carnations, 5 yellows are needed, which leaves us with 8 total carnations. So for 60 white, the total is:

3 white - 8 total

60 white - x total

So

3x = 60*8

Dividing both sides by 3

x = 20*8 = 160

The correct answer is given by option D.

Let f(x)=x+3 and g(x)=1/x. The graph of (f*g)(x) is shown below.
Vlad [161]
For this case we have the following functions:
 f (x) = x + 3&#10;&#10;g (x) = 1 / x When composing the functions we have:
 (fog) (x) = f (g (x))&#10;
 Substituting values we have:
 (fog) (x) = ((1 / x) +3)&#10;
 Rewriting:
 (fog) (x) = 1 / x + 3&#10;
 The function has a horizontal asymptote at y = 3.
 Therefore, the range of the function is all reals minus y = 3.
