Find the measure of arc EC.

(A) 50

Step-by-step explanation:

50

Step-by-step explanation:

This is the formula

= 1 / 2(SUM of Intercepted Arcs)

Applying it to your question, that means

7x equals half of (5x + 90)

Once you solve for x, remember that the question is asking for the measure of arc EC

so 5 * x is your final answer

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! : )

95.03 is the answer. hope this !
