Apecan pie is being served for dessert. one piece of pie has an arc length of 7.85 in. it has been cut into 8 equal pieces. what is the radius of the pecan pie? (round to the nearest whole number)

10 inches.

Step-by-step explanation:

Since the pecan pie is a circle, you can use this formula:

Where "r" is the radius and is the central angle of the arc in radians.

If the pecan pie has been cut into 8 equal pieces then the central angle is:

Now you know the arc length and the central angle, then, you can solve for "r" from  :

Substituting values, you get that the radius of the pecan pie rounded to the nearest whole number is:

i hope this answer you! if you have any further questions or concerns, feel free to ask! : )

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! : )
