Diameter= 2 times the radius

2r=d
2r=10.2
R= 10.2/2
R=5.1

Therefore, the radius is 5.1 units which makes the answer choice C correct.

Hopefully, this helps!

Answer:

c 5.1

Step-by-step explanation:

The diameter of the circle is 102.

The radius is half of the diameter

r =d/2

r =10.2 /2 =5.1

10 have volunteered to help with the preparations for a party. How many ways can Susan assign someone to buy beverages, someone

Lesechka [4]

Answer:

The answer is 720 ways.

Step-by-step explanation:

Total friends who volunteered = 10

Total number of jobs that have to be done = 3

Here order matters, so it is a permutation question.

We can use the formula nPr.

= $\frac{10!}{7!}$

= 720 ways.

The second way to solve this is:

Susan can choose the first person to do a job in 10 ways

Then the second job can be done in 9 ways and the third in 8 ways.

Total becomes = $10\times9\times8=720$ ways

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>
