Solution:
Given:
A circle with the sector details;
The area of a sector is given by;
Therefore, the area of the sector is;
D) is the correct answer.
Answer:
n = 17.
Step-by-step explanation:
The opposite angles of a parallelogram are congruent so we have:
4n - 2 = 2n + 32
4n - 2n = 32 + 2
2n = 34
n = 17.
A+B+C=$408
C+7
x+x+5
You can use these examples to find the word problem answer.
Answer:
Absolutely convergent
0.82
Step-by-step explanation:
Use the alternating series test.
lim(n→∞) (1/√n) = 0
1/√n > 1/√(n+1) for n > 0
It is absolutely convergent.
Use error estimation.
1/(n+1)² < 0.01
(n+1)² > 100
n+1 > 10
n > 9
n = 10
Sum the first 10 terms.
∑₁¹⁰ (-1)ⁿ⁻¹/n²
= 1/1² − 1/2² + 1/3² − 1/4² + 1/5² − 1/6² + 1/7² − 1/8² + 1/9² − 1/10²
≈ 0.82
