What is the equation in standard form of a parabola that contains the following points (-2, -,-,-20) a: y= -2.5x^2 + 5x b: y= -x^2 +4x-4 c y= -2x^2 +4x-4 d y= -2.25x^2 +4.5x -2

I  believe your answer is C) y = -2x^2 + 4x - 4

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
