Answer:

The answer is:

$\frac{2a}{2b} = 5$

Step-by-step explanation:

Substitute the values of a and b into the equation

$a = 10&b = 2 \\ \\ \frac{2a}{2b} = 5 \\ \\so \frac{2(10)}{2(2)} = 5$

$\frac{20}{4} = 5 \\ \\ 5 = 5$

What is the length of the conjugate axis?<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B%28x-2%29%5E2%7D%7B36%7D%20-%20%5Cfrac

Answer:

the length of the conjugate axis is 16

Step-by-step explanation:

We know that the general equation of a hyperbola with transverse horizontal axis has the form:

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

Where the point (h, k) are the coordinates of the center of the ellipse

2a is the length of the transverse horizontal axis

2b is the length of the conjugate axis

In this case the equation of the ellipse is:

$\frac{(x-2)^2}{36} + \frac{(y+1)^2}{64} = 1$

Then

$b^2 = 64\\\\b = \sqrt{64}\\\\b = 8\\\\2b = 16$

Finally the length of the conjugate axis is 16

D - 8 divided by 5 = -4 d =

elena55 [62]

D = 0.32

d - 8 / 5 = -4d

d - 1.6 = -4d
d + 4d = 1.6
5d = 1.6
d = 0.32

This is an exact question in my math textbook. It should be correct.

Explain what happens to the cross products when the terms of a proportion are cross multiplied.

Temka [501]

Answer:

The cross product is created

Step-by-step explanation:

A proportion is simply a statement that two ratios are equal. ... In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

I hope this helped :)
