Step-by-step explanation:

it is the vertex form.

remember, (h, k) is the vertex point.

the vertex being the point of the (quadratic) parabola, where the curve turns around.

depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.

so, the first a. is correct.

and so is the second a., as they play an important role when completing the square and hence finishing the transformation.

A soccer team made 76 penalty shots out of 100.Which ratio represents successful penalty shots to missed penalty shots?

almond37 [142]

Sense we are wanting to find <u>how many were miss</u>, then, we are practically going to subtract the following:

$\boxed{76-100}= \ \left[\begin{array}{ccc}\bf{24\end{array}\right]$

So, from this begin understood, we would then combine both the penalties that were shotted, to the onces that weren't.

So, b subtracting these both, we would grab the result, and then smash that with the number of the penalties that were made in.

Your answer: $\boxed{\bf{76:24}}$
