William is in the middle of swimming in a ten-mile race. He swims at a steady speed, and then slows down, stops to eat,
swims faster to get back in the race, and returns to a steady speed. He later stops for water, and then again swims faster to
get back in the race. Which graph best represents the situation?

central angle of a triangle has the same measure as its intercepted arc.

step-by-step explanation:

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two

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.
