Answer:

The area of the circle is $9 \pi\ units^{2}$ or $28.26\ units^{2}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ units$ ----> the radius is half the diameter

substitute

$A=\pi (3)^{2}=9 \pi\ units^{2}$ -----> exact value

assume

$\pi=3.14$

$A=9(3.14)=28.26\ units^{2}$

Find (f•g)(x) for the given functions: f(x) = 5/x and g(x) = 3 + x/5.

Tema [17]

Answer: (f•g)(x) = (15 + x)/x

Explanation:
F(x) = 5/x and g(x) = 3 + x/5

Then (f•g)(x) = 5/x • 3 + x/5

(f•g)(x) = 5/x • 15/5 + x/5

(f•g)(x) = 5/x • (15 + x)/5

(f•g)(x) = 5(15 + x)/5x

(f•g)(x) = (15 + x)/x
