Answer:

Step-by-step explanation:

3. slope of CB = rise/run = 5/12      BF = 5    CF = 12

BF ⊥ DF

DB (seg of two farthest points) = √BF²+DF² = √5²+32² = √1049 = 32.4

4. f(x) = 2x² - 5x -3      vertex : A (h,k)  for f(x) = ax² + bx +c

h = - b/2a = - (-5 / 4) = 5/4

f = f(h) = 2*(5/4)² - 5*(5/4) - 3 =25/8 - 25/4 -3 = -49/8

A (5/4 , - 49/8) i.e. (1.25 , - 6.13)

negative root:   2x² - 5x -3 = (2x+1) (x- 3)      x = - 1/2      y = 0

B (- 1/2 , 0)

x coordinate of AB: 1/2 (1.25 + -0.5) = 0.375

Ainat [17]
3 slices

This is because 1/4 of 12 is 3.
This is right because 3 x 4 = 12.
