option 1

Step-by-step explanation:

40ft is radius

first lets find the area of the whole circle

A=pi*r^2

A=pi*40^2

A=pi*1600

A=5026.54824574 ft^2

now, lets find what part of a circle is 80 degrees

80/360=2/9

now lets multiply the total area by the fraction to find what area is actually getting sprinkled

A=5026.54824574*(2/9)

A=10053.0964915/9

A=1117.01072128

A= around 1117.01 ft^2

unless if u could do my questions, if not i wouldn't want to

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! : )
