The quantities x and y are proportional

Furkat [3]

Answer:

$r = \frac{1}{4}$

Step-by-step explanation:

Given

The x and y values

Required

Determine the constant of proportionality

This is calculated from:

$y = rx$

Pick any corresponding x and y values:

$x = 8$ and $y = 2$

Substitute 8 for x and 2 for y in $y = rx$

$2 = r * 8$

Make r the subject

$r = \frac{2}{8}$

$r = \frac{1}{4}$

Pick another x and y values:

$x = 16$ and $y = 4$

$r = \frac{4}{16}$

$r = \frac{1}{4}$

<em>Hence, the constant of proportionality is 1/4</em>

Which conic section does the equation below describe?

Rus_ich [418]

Answer: Option C. Ellipse

Step-by-step explanation:

The general equation of an ellipse has the following form:

$\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1$

Where the point (h, k) is the center of the ellipse

In this case we have the equation

$\frac{(x-9)^2}{4} + \frac{(y+2)^2}{25} =1$

Note that its shape matches that of a ellipse with center (9, -2)

$a=\sqrt{4} \\a=2\\\\\\b=\sqrt{25}\\b=5$

Therefore the answer is the obtion C
