A building casts a 50-foot shadow. Alex is 5 feet tall and casts a 6-foot shadow. Approximately how tall is the building?

D.
You have to make a proportion. Set it up 5/6 = x/50. Then cross multiply. 5x50=250. 6 x <em>(x)</em> = 6x. 6x=250. 250/6=41.66666. x=41.6666. Round up, and the building is about 42 ft. tall.

Write the vertex form of the equation of the parabola which has a vertex of (0,0) and contains the point (2,-2)

Anettt [7]

$\bf \qquad \textit{parabola vertex form}\\\\
\begin{array}{llll}
\boxed{y=a(x-{{ h}})^2+{{ k}}}\\\\
x=a(y-{{ k}})^2+{{ h}}
\end{array} \qquad\qquad vertex\ ({{ h}},{{ k}})\\\\
-------------------------------\\\\
y=a(x-{{ h}})^2+{{ k}}\qquad 
\begin{cases}
h=0\\
k=0
\end{cases}\implies y=a(x-0)^2+0
\\\\\\
y=ax^2\qquad 
\begin{cases}
x=2\\
y=-2
\end{cases}\implies -2=a2^2$

solve for "a", to get the coefficient, and then plug it back in the equation.
