Answer:

Choice 3

Step-by-step explanation:

A=pi*r squared

Diameter= 10, 10/2= 5

Radius=5

A=pi* (5)^2

A= 78.54...

The area of the circle is 78.5 meters squared.

Answer:

Area of a circle=pi*(radius)^2

Diameter=2*radius

=> radius=5 m

Area=3.14*(5)^2=3.14*25=78.5 m^2

Answer:

16 + 3n

Step-by-step explanation:

a = 19 ; common difference = 22 - 19 = 3

a(n) = a + (n -1 ) *d

= 19 + (n-1)*3

= 19 + 3n - 3

= 16 + 3n

What are the restrictions of the domain of the function F(x) = 1/x^2-9

Sonbull [250]

$f(x)=\frac{1}{x^2-9}$

The denominator can't be equal to 0.
$x^2-9 \not= 0 \\
x^2 \not= 9 \\
x \not= -3 \ \land \ x \not= 3$

The domain is all numbers except -3 and 3.
$x \in \mathbb{R} - \{-3, 3 \}$
