That would be a true statement.
Two angles are supplementary if they add up to 180 degrees.
Given the angle 76 degrees, the supplement is 180-76 degrees, or 104 degrees.
Answer:
√x
Step-by-step explanation:
Step 1: First, simplify -3⁄6 to -½.
Step 2: According to the Negative Exponential Rule, you bring the denominator to the numerator while ALTERING THE INTEGER SYMBOL FROM NEGATIVE TO POSITIVE:
bⁿ = 1\b⁻ⁿ
Step 3: Again, using the Definition of Rational Exponents, rewrite this rational exponent as a radical:

Answer:
5
Step-by-step explanation:
The nth term of a geometric series is:
a_n = a₁ (r)^(n-1)
where a₁ is the first term and r is the common ratio.
Here, we have:
40 = a₁ (r)^(4-1)
160 = a₁ (r)^(6-1)
40 = a₁ (r)^3
160 = a₁ (r)^5
If we divide the two equations:
4 = r^2
r = 2
Now substitute into either equation to find a₁:
40 = a₁ (2)^3
40 = 8 a₁
a₁ = 5
