Answer:

Step-by-step explanation:

$y=-x^2-4x-1\\=-(x^2+4x+4)+4-1\\=-(x+2)^2+3\\\\Vertex=(-2;3)\\\\$

$y+x^2+2=0\\y=-x^2-2\\\\y=-(x-0)^2-2\\Vertex=(0;-2)\\$

Marta is solving the equation S = 2Πrh + 2Πr2 for h. What is the result?

yulyashka [42]

<span>S = 2Πrh + 2Πr2
Manipulating the equation for h.
Step 1. subtract </span><span>2Πr2 on both sides.

</span>S - 2Πr2 = 2Πrh + 2Πr2 - 2Πr2
S - 2Πr2 = <span>2Πrh
</span>
Step 2 . divide <span>2Πr on both sides
</span>
(S - 2Πr2)/2Πr = 2Πrh/<span>2Πr

</span><span>h = </span>(S - 2Πr2)/2Πr
