Find the exact circumference of a circle with an area equal to 36 sq. in.

The exact circumference of a circle is, inches

Step-by-step explanation:

Area(A) and circumference(C) of the circle is given by:

where, r is the radius of the circle.

As per the statement:

an area equal to 36 sq. in.

⇒A = 36 sq. in.

then;

Divide both sides by  we have;

or

⇒

⇒

We have to find the exact circumference of a circle.

then;

⇒ inches

Therefore, the exact circumference of a circle is, inches

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
