Answer:

(f • g)(x) = x² - 6x + 7

Step-by-step explanation:

Suppose

f(x) = x² - 2

g(x) = x - 3

Determine

(f • g)(x) = ...

We can compose the functions by doing the following

(f • g)(x) = f(g(x))

(f • g)(x) = f(x - 3)

(f • g)(x) = (x - 3)² - 2

(f • g)(x) = x² - 6x + 9 - 2

(f • g)(x) = x² - 6x + 7

I hope this helps!

last week the price of oranges at the farmers market was $1.75 per pound this week a price has decreased by 20% what is the pric
Nuetrik [128]

Answer:

Find out the what is the price of oranges this week .

To prove

As given

last week the price of oranges at the farmers market was $1.75 per pound.

This week a price has decreased by 20% .

20% is written in the decimal form

= \frac{20}{100}

= 0.20

Decreased in the price = 0.20 × 1.75

                                       = $0.35

The price of oranges this week = Price of orange at last week - Decreased in the price

                                                     = $1.75 - $0.35

                                                     = $ 1.4

Therefore the  price of oranges this week is $1.4 .

Find the area of the figure. Use 3.14 for 77.
Alecsey [184]

Answer:

C 70.26 in2

Step-by-step explanation:

6 = D

R = D/2

R = 3

A = 3.14 x 3 x 3

A = 3.14 x 9

A = 28.26

The area of the triangle is

A = 6 x 7

A = 42

So

42 + 28.26

70.26 in2
