Bonus:
Give the vertex for the parabola with the equation f(x) = -3x² + 6x + 24

(1,27)

Step-by-step explanation:

Knowing the formula to find the vertex of a parabola as -b/2a=x

In the equation b=6 and a=-3

Thus, -(6)/2(-3)=1

Plug in 1 back to the equation

-3(1)^2+6(1)+24

= -3+6+24

=27

(1, 27)

Step-by-step explanation:

What I did was graphed it, and looked for the highest or lowest point. That point will be the vertex.

Hope this helps

answer:   rlly

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
