Justin wants to cover the top of his circular swimming pool to keep bugs out of the pool. The diameter of his pool is 20 feet. What is the area of the pool cover

Step-by-step explanation:Area of a circle is πr2

Diameter of the cover is 20feet

Radius= diameter/2

Radius= 20/2

Radius= 10 feet

Since 1feet = 0.3045m

Then 10feet =3.045m

Area= 3.142*3.045*3.045

Area= 29.133m2

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
