Answer:

The answer is D.

Step-by-step explanation:

The x and y pairs shown in the table have product values: 818, 720 and 776. So the product xy is not constant and it is not an inverse variation. The answer is D.

Answer:

<h2>D. The product xy is not constant, so the relationship is not an inverse variation.</h2>

Step-by-step explanation:

If the relationship is inverse variation, then the product xy is constant.

2 · 409 = 818

3 · 240 = 720

4 · 194 = 776

The product xy is not constant.

HELP ME Write and solve a proportion to find y.

Phoenix [80]

Given:

A figure of dilation and the center of dilation is O.

To find:

The value of y.

Solution:

The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).

$d'\propto d$

$d'=kd$

$\dfrac{d'}{d}=k$

Where, k is the scale factor or constant of proportionality.

So, the scale factor for the given dilation is

$k=\dfrac{OB'}{OB}$

$k=\dfrac{36}{16}$

$k=\dfrac{9}{4}$

We know that,

$k=\dfrac{\text{Side length of image}}{\text{Corresponding side length of original figure}}$

$\dfrac{9}{4}=\dfrac{A'C'}{AC}$

$\dfrac{9}{4}=\dfrac{27}{y}$

$9\times y=27\times 4$

Divide both sides by 9.

$y=\dfrac{27\times 4}{9}$

$y=3\times 4$

$y=12$

Therefore, the value of y is 12.

Write an equation in standard form of an ellipse that is 8 units high and 18 units wide. The center of the ellipse is (0,0)

zhenek [66]

Check the picture below.

$\bf \begin{cases}
h=0\\
k=0\\
a=9\\
b=4
\end{cases}\implies \cfrac{(x-0)^2}{9^2}+\cfrac{(y-0)^2}{4^2}=1\implies \cfrac{x^2}{81}+\cfrac{y^2}{16}=1$
