a. Notice that
1/(1*2) = 1/2 = 1 - 1/2
1/(2*3) = 1/6 = 1/2 - 1/3
1/(3*4) = 1/12 = 1/3 - 1/4
and so on, which suggests the n-th term of the sum can be written as
Then the sum itself is telescoping:
b. The proof is trivial:
so the formula found in (a) is correct.
Answer:
Step-by-step explanation:
We can find the distance using the distance formula:
We then substitute (1,7) as 
and (-3,-1) as 
.
8,516.90 has a greater value than 8,516.50 because .90 is closer to 1.00 than .50 is
