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>

1. Eight people work in an office. They are paid hourly rates of 12£,15£,15£,14£,14£,13£,14£,13£

bearhunter [10]

Answer:

mean=110/8 =13.75 pounds; median=14 pounds; mode=14 pounds; average=13.75 pounds

Step-by-step explanation:

mean=add all the numbers together to get total then divide that total by the number of amounts present 12, 15, 15, 14, 14, 13, 14, 13 =110, then 110/8=13.75 pounds

mode=arrange amounts in order (smallest to largest), then determine which amount appears more than the other amounts 12, 13, 13, 14, 14, 14, 15, 15 =14 appears the most

median=organize numbers from smallest to greatest, count how many there are, then determine which number appears in the middle of all of them 12, 13, 13, 14, 14, 14, 15, 15 = there are 8 numbers present but 14 is in the middle; answer =14

average= take total of mean, then divide it by the number of amounts that appear 110/8 =13.75

The is for a test could anybody please help me

postnew [5]

Answer:

6 bags (?)

Step-by-step explanation:

If 1/4 of a bag is 1/24 of the rainbow, then we can assume 4/4 of a bag is 4/24 of the rainbow.

From there, we can just do 24 ÷ 4 = 6

Therefore, you would need 6 bags to cover the entire rainbow.

Help me please due today!

Answer:

Yes

Step-by-step explanation:

In the first 1, the input 2 repeats which makes it not a function

in the second one each input is unique and does not repeat so it is a function

in the third one the input 1 repeats and makes it not repeat

And in the last one each input is unique

If inputs (the x value) repeat it's not a function
