Data:
B (Larger base) = 28 m
b (Minor base) = 18 m
h (height) = ?
A (area) = 475 m²

Formula:
$A = \frac{(B+b)*h}{2}$

Substitute:
$475 = \frac{(28+18)*h}{2}$
$475 = \frac{\diagup\!\!\!\!\!46^{23}*h}{\diagup\!\!\!\!2^1}\:\:\to\:\:\:475 = 23*h\:\:or\:\:\boxed{\boxed{23h = 475}}$

Answer:
$\textcircled{ A } 23h = 475$

Answer:

The parent function is $f(x)=a(x-h)^{2} +k$

That Parabola's equation is $f(x)=x^{2}$

Step-by-step explanation:

I can't really explain much, but the top equation is a formula for all equations for a parabola. h and k are the x and y-values of the vertex. a is, well, a.

How did I find the equation of the parabola? Simple. Since the vertex is on the origin, h and k are 0. Also, because it intercepts (2,4) and (1,1), a=1.

Answer:

(-7,-15)

Step-by-step explanation:

We can substitute first y in the second y. Both equations are also functions. We can merge the equations.

$2x - 1 = x - 8 \\ 2x - x = - 8 + 1 \\ x = - 7$
