Let a, b, and c be real numbers where a ≠ b ≠ c ≠ 0. Which of the following functions could represent the graph below? a. f(x) = x2(x – a)2(x – b)4(x – c)
b. f(x) = x3(x – a)3(x – b)(x – c)2
c. f(x) = x4(x – a)(x – b)3(x – c)3
d. f(x) = (x – a)2(x – b)(x – c)6

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

the radius is 2 times the diameter.
