Answer:
a = 23 degrees (brainliest?)
Explanation:
<em>supplementary line </em>is <u>180 degrees</u>
180 - 157 = 23
The two numbers of -5,5,-3,and 8 that have the same absolute value is -5, and 5
Answer:
A and B: Isosceles (having two sides of equal length)
C: Equilateral (all sides are equal)
Answer:
An explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Step-by-step explanation:
Given the geometric sequence

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

Determining the common ratios of all the adjacent terms

As the ratio is the same, so
r = 4
Given that f₁ = -1/2
substituting r = 4, and f₁ = -1/2 in the nth term


Thus, an explicit representation for the nth term of the sequence:

It means, option (B) should be true.
Yes it is because 18÷6 is 3 and 6×3=18
