Find the following (u•w)(2)= (w•u)(2)=

Mathematics
1 answer:
Viefleur [7K]3 years ago
5 0

Answer:

(u \circ w)(2) = -34

(w \circ u) = -49

Step-by-step explanation:

We are given these following functions:

u(x) = 4x + 2

w(x) = -5x + 1

The first step to solve this question is finding the composite functions. So

(u \circ w)(x) = u(w(x)) = u(-5x+1) = 4(-5x + 1) + 2 = -20x + 6

(w \circ u)(x) = w(u(x)) = w(4x + 2) = -5(4x+2) + 1 = -20x - 9

At x = 2

Now we replace x by 2 in each of the functions. So

(u \circ w)(2) = -20(2) + 6 = -40 + 6 = -34

(w \circ u)(2) = -20(2) - 9 = -40 - 9 = -49

It is A. We have a ratio of

900 workers : 3.2×10⁵

Dividing by 9×10² becomes

1 worker :\frac{3.2}{9} ×10³

3.2/9 is just 0.36 rounded so it is

1 worker : 0.36×10³
