Acircular mirror is surrounded by a square metal frame. the radius of the mirror is 3x. the side length of the metal frame is 15x. what is the area of the metal frame? (type your answer in factored form. type an exact answer in terms of pi.

the area of the frame is __ square units.

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
