Which of the following terms appear in the expansion of (x + y)10? the letter a in each term represents a real constant. a. ax3y7 b. ay5 c. ax5 d. ax5y

The correct option is:

A.  

Step-by-step explanation:

We are asked which term would appear in the expansion of:

Clearly all the terms of this expansion will have the sum of powers of x and y    =10

In our given options the sum of powers of x and y are:

A.      sum of powers=3+7=10

B.            sum of powers=5

C.            sum of powers=5

D.           sum of powers=5+1=6

Hence, the correct option is:

A.  

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6
