How would you find the coefficient of the third term in (x+5)^7?

The answer is option B

Step-by-step explanation:

To find the coefficient of the third term in

Rewrite the expansion in the form

where n is the index

So we have

After that we use the formula

where r is the term we are looking for

For the third term we are looking for the term containing x²

that's

r + 1 = 3

r = 2

So to find the coefficient of the third term

We have

Hope this helps you

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
