The vertex of this parabola is at (-1,-3) which of the following could be its equation
Gnesinka [82]
Since these are parabolas with y being squared, the standard form of such a parabola with vertex at (h, k) is 

<span>x = a(y - k)^2 + h </span>

<span>There are no steps. Just look at what is inside the parentheses and compare it to (y - k) with k = -3. </span>
<span>Then look at what is added and compare it to h = -1. </span>

<span>For instance, A has (y + 1) in parentheses. So k = -1. And it has -3 added, so h = -3. That would be a vertex at (-3, -1).</span>

Nick buys a sleeping bag online for $70.16. If shipping and handling are an additional 25% of the price, how much shipping and h
DiKsa [7]

Answer:

$17.54

Step-by-step explanation:

Given the following question:

25% of 70.16

To find the answer we simply use the formula to calculate percentages to find 25% of 70.16. Of course, round if needed.

\frac{p\times n}{100}
\frac{25\times70.16}{100} =1754\div100=17.54
=17.54

The sleeping bags shipping, and handling will cost "$17.54."

Hope this helps.
