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.
= 
= 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 =
ways

Answer: B) The lengths of both transverse axes are the same.
Step-by-step explanation: Given Hyperbola equations :
and

First one :
is a Horizontal Hyperbola.
a = 3 and 2a = 6.
Length of transverse axis = 6.
And second one :
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>
