Write the equation of the parabola that has the vertex at point (2,-11) and passes through the point (0,5).

aleksandr82 [10.1K]

$~~~~~~\textit{vertical parabola vertex form} \\\\ y=a(x- h)^2+ k\qquad \begin{cases} \stackrel{vertex}{(h,k)}\\\\ \stackrel{"a"~is~negative}{op ens~\cap}\qquad \stackrel{"a"~is~positive}{op ens~\cup} \end{cases} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\stackrel{vertex}{(\stackrel{h}{2}~~,~~\stackrel{k}{-11})}\qquad y=a(x-2)^2-11\qquad \qquad \textit{we also know that} \begin{cases} x=0\\ y=5 \end{cases} \\\\\\ 5=a(0-2)^2-11\implies 16=4a\implies \cfrac{16}{4}=a\implies 4=a \\\\[-0.35em] ~\dotfill\\\\ ~\hfill y=4(x-2)^2-11~\hfill$

Answer:

The probability of picking a purple marble and spinning green is $\frac{3}{28}$ .

Step-by-step explanation:

Since there are 7 marbles and 8 possible tiles to spin, the total amount of possible outcomes are 56. Out of the 56 different outcomes, 6 of them meet the requirement of picking a purple marble and spinning green, so the fraction to represent the situation is $\frac{6}{56}$ or $\frac{3}{28}$ .
