The slope of cd is 4/3 which segments are perpendicular to cd

Anything with a slope of -3/4

Step-by-step explanation:

I can't answer which segments specifically because I can't see the choices.  With slope though perpendicular slopes are what is called the negative reciprocal.  That just means you take the slope, make it negative and flip it.  if it's not a fraction then you put a 1 over it.

So a slope of 5/7 is perpendicular to -7/5 and a slope of 3 would be perpendicular to a slope of -1/3.

here we have 4/3, so make it negative, -4/3, then flip it, -3/4

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.

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
