A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *

Answers

9514 1404 393

Answer:

  y = x^2 +2x -8

Step-by-step explanation:

For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.

  y = (x -2)(x -(-4))

  y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property

  y = x^2 +4x -2x -8 . . . . use the distributive property again

  y = x^2 +2x -8 . . . . . . . .equation in standard form

Use the figure to find the measures of the numbered angles?

Answers

61 degrees = angles 1, 3, 6
119 degrees = angles 2, 4, 5, 7

The red angle is vertical to angle 6. Since vertical angles are congruent, angle 6 = 61.

The red angle corresponds to angle 1, and angle 6 corresponds to angle 3. Since corresponding angles are congruent, angle 1 and angle 3 = 61.

The red angle and angle 4 are consecutive interior angles, which are supplementary. So 180 - 61 means angle 4 is 119.

4 and 2 are vertical so angle 2 is 119

4 and 7 are corresponding and 2 and 5 are corresponding so 7 and 5 are 119.
