Answer:
is the exact answer
2.83 is the answer to the nearest 100th
Step-by-step explanation:
I think the equation should be
(x-5)^2 + (y+7)^2 = 8 instead of (x-5)^2 + 4+7)^2 = 8
= 8
r =
is the exact answer
2.83 is the answer to the nearest 100th
Given:
First term of an arithmetic sequence is 2.
Sum of first 15 terms = 292.5
To find:
The common difference.
Solution:
We have,
First term:
Sum of first 15 terms:
The formula of sum of first n terms of an AP is
Where, a is first term and d is common difference.
Putting , n=15 and a=2 in the above formula, we get
Divide both sides by 15.
Dividing both sides by 7, we get
Therefore, the common difference is 2.5.
