Answer:

Step-by-step explanation:

Factorize 175 and 50

175 = 5 * 5 * 7

50 = 5 * 5 * 2

$\frac{\sqrt[3]{175}}{\sqrt[3]{}50}=\sqrt[3]{\frac{175}{50}}\\\\\\ =\sqrt[3]{\frac{5*5*7}{5*5*2}}\\\\\\=\sqrt[3]{\frac{7}{2}}$

Heather is going to graph y = -3x2 + 3. How is the parent graph transformed?

Yuki888 [10]

Any x² graph is a parabola. The negative in front is going to flip the parabola upside down to look like a camel hump. The 3 is going to make the graph narrower. The three at the end makes the y intercept 3. So the top of the graph will be shifted up to (0,3).
The answer would be A I believe

What is the volume of the square pyramid with base edges 18 m and slant height 15 m

vlada-n [284]

check the picture below.

so it has a base of 18x18 and a height of that much.

$\bf \textit{volume of a pyramid}\\\\ V=\cfrac{1}{3}Bh~~ \begin{cases} B=area~of\\ \qquad its~base\\ h=height\\ ------\\ B=\stackrel{18\times 18}{324}\\ h=12 \end{cases}\implies V=\cfrac{1}{3}(324)(12)\implies V=1296$
