A quadratic function f is defined by f (x) = (2+6) (x – 8). 1. Without graphing, identify the x-intercepts of the graph of f. Explain how you know.

2. Expand (x + 6) (2 - 8) and use the expanded form to identify the y-intercept of the graph of f. Show your work and explain how you know.

1. The x-intercepts can be determined by taking the opposite of the constants, in this case the x-ints are -6 and +8.

2. (x+6)(x-8)  =  x^2+-2x-48, the y-intercept is -48

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
