Answer:

8 ft^2

Step-by-step explanation:

$\frac{h1}{2ft} =\frac{h2}{3ft} \\\\$

area of ABC is:

$A= \frac{(3ft)(h2)}{2}$

area of ABC is 18 square ft, then

$h2 = \frac{(area)(2)}{3ft} = \frac{(18 ft^2)(2)}{3ft} =12ft$

now you can find h1 and the area for EFG

The graph of a quadratic function contains (4,-64) and it's vertex is at the origin.write an equation for this function.

lesya692 [45]

Answer:

Step-by-step explanation:

Not sure what form you need this in, but it really doesn't matter, as you'll see in the final equation. I used the vertex form and solved for a:

$y=a(x-h)^2+k$

We are given the vertex (h, k) as the origin (0, 0), and we have a point that the graph goes through as (4, -64). That's our x and y. Plugging in what we have:

$-64=a(4-0)^2+0$ gives us

-64 = 16a and

a = -4. That means that the quadratic equation is

$y=-4x^2$ which is both vertex form and standard form here, no difference.
