Which is a true statement comparing the graphs of x^2/3^2 - y^2/4^2= 1 and y^2/3^2 - x^2/4^2 = 1?

laila [671]

Answer: B) The lengths of both transverse axes are the same.

Step-by-step explanation: Given Hyperbola equations :

$\frac{x^2}{3^2}-\frac{y^2}{4^2}=1$ and

$\frac{y^2}{3^2}-\frac{x^2}{4^2}=1$

First one : $\frac{x^2}{3^2}-\frac{y^2}{4^2}=1$ is a Horizontal Hyperbola.

a = 3 and 2a = 6.

Length of transverse axis = 6.

And second one : $\frac{y^2}{3^2}-\frac{x^2}{4^2}=1$ is a Vertical Hyperbola.

b=3 and 2b = 6

Length of transverse axis = 6.

The lengths of both transverse axes are the same.

Therefore, correct option is B option :

<h3>The lengths of both transverse axes are the same.</h3>

How many whale sharks would a researcher need to measure so that 90% confidence level would have a margin of error of 0.25

Vika [28.1K]

About 1407 sharks would be needed to have a margin of error of 0.25

<h3>What is margin of error?</h3>

Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:

$E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }$

The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

$0.25=1.645*\frac{5.7}{\sqrt{sample\ size}}\\ \\sample\ size=1407$

About 1407 sharks would be needed to have a margin of error of 0.25

In September, John read a total of p pages. In October, he read twice as many pages than he read in September, and in November,

aleksandrvk [35]

Ok so to start let's put everything we know in some expressions

Words: In September, John read a total of p pages.

September: p

Words: In October, he read twice as many pages than he read in September

October: 2p

Words: November, he read triple the number of pages that he read in October

November: 3 x October

Then, we know what October is (2p), so we can substitute it into the third expression to get 3 x 2p or 6p. In November, John read 6p pages, or 6 times as many as he read in September.

Note: The fact that he read 120 pages in December is just in there to distract you. It's never connected to any of the other months, and since our equation can be in terms of p we don't need to know the actual number of pages

If I can help with anything else just let me know :)
