ANSWER
EXPLANATION
The given binomial expansion is:
Compare this to
we have a=2x , b=-3y and n=10
We want to find the coefficient of the term
This implies that, r=5.
The terms in the expansion can be obtained using
We substitute the given values to obtain;
Hence the coefficient is;
To get their combined time, get the sum of Vega's time and Janice's
Therefore, their combined time for their part of the relay is 53.659 seconds.
