Answer:
Step-by-step explanation:
Lets x =measure of arc JK
37 = 1/2 (45 + x)
74 = 45 + x
74 - 45 = x
29 = x
or
x = 29
answer
B. 29
Answer: 11/12
Step-by-step explanation: You need to make 4/6 by multiplying it by 2. 4/6 would become 8/12. You would then add it by 3/12 getting 11/12.
We know that
The Euler's formula state that, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
V - E + F = 2
clear F
F=2-V+E
in this problem
V=8
E=14
F=?
so
F=2-8+14
F=8
the answer is8 faces
Let denote the <em>k</em>th term of the sequence. Then
where <em>d</em> is the common difference between consecutive terms in the sequence and <em>a</em>₁ is the first term.
The sum of the first <em>n</em> terms is
From the formula for , we get
So we have , and so that .
Then the <em>n</em>th term in the sequence is
