The vertex of the parabola below is at the point (-3, -5). which of the equations below could be the one for this parabola?

marysya [2.9K]

Answer:

Step-by-step explanation:

The coordinates of a vertex are (h, k). If our vertex is (-3, -5), then h = -3 and k = -5. The vertex form of a parabola is

$y=(x-h)^2+k$ so if we fill in our h and k values, the equation becomes

$y=(x-(-3))^2+(-5)$ and, simplified, is

$y=(x+3)^2-5$

Choice B.

Find x and y. please I need help its so confusing

IrinaVladis [17]

Sin 30=opposite side/hypotenuse =8/x
1/2=8/x so 1•x=2•8; x=16

Sin60= opposite side/hypotenuse=y/16
(Sqrt 3)/2=y/16 so 2•y=16• sqrt 3; y=13.856

Factor the expression

DiKsa [7]

Answer:

Step-by-step explanation:

Your difference of perfect cubes formula is given as

$(a-b)(a^2+ab+b^2)$ and you have already correctly identified a as $5q^2$ and b as $r^2s$ . So we fill in the formula as follows:

$(5q^2-r^2s)((5q^2)^2+(5q^2)(r^2s)+(r^2s)^2)$ and we simplify. Remember that

$(5q^2)^2=(5)^2*(q^2)^2=25q^4$ . It's important that you remember the rules.

Simplifying then gives us

$(5q^2-r^2s)(25q^4+5q^2r^2s+r^4s^2)$

That's it, so fill it in however you need to on your end. Learn the patterns for the sum and difference of cubes and it will save you a ton of headaches...promise!!
