Find the slope of the slope through the points (-4 , -4) and (2,5)
Colt1911 [192]

Answer:

3/2

Step-by-step explanation:

In order to find the slope with two points, you use this formula:

y2-y1 / x2 - x1.

y2 is 5 and y1 is -4. 5 - -4 = 9

x2 is 2 and x1 is -4. 2 - - 4 = 6

9/6 = 3/2.

The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape
Pie

Answer:

  • vertex: (-5/8, 7/16)
  • axis of symmetry: x = -5/8

Step-by-step explanation:

For quadratic ax²+bx+c, the axis of symmetry is located at x=-b/(2a).

Here, we have a=4, b=5, so the axis of symmetry is ...

... x = -5/(2·4) = -5/8

_____

The vertex y-value will be f(-5/8).

... f(-5/8) = (4·(-5/8) +5)·(-5/8) +2 = (5/2)·(-5/8) +2 = -25/16 +32/16

... f(-5/8) = 7/16

_____

The axis of symmetry is x = -5/8; the vertex is (-5/8, 7/16).
