What is the coefficient of the x5y5-term in the binomial expansion of (2x – 3y)10? 10c5(2)5(3)5 10c5(2)5(–3)5 –10c5(2)5(–3)5 10c5(2)5(3)

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;

answer: haha (: i’ll go see what it is

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
