(-2)^4=16
(-2)^-1=-1/2
-1/2x16=-8
Answer: -8
Answer:
A ≈ 78.54
Step-by-step explanation:
Area of a circle is A=πr^2
Since you do not know r (radius) you take the formula for the circumference of a circle (C=2πr), plug in 31.4 for C, and solve for r
Now that you have the radius of 4.99746521, you round it up to 5 and solve the area formula with 5 in as r.
The place with the best buy between village market and Sam's club is Sam's club at $0.59 per can.
<h3>Unit rate</h3>
Village market:
- Green beans = 5 cans
- Total cost = $3.70
Unit rate = Total cost / green beans
= 3.70 / 5
= $0.74 per can
Sam's club:
- Green beans = 10 cans
- Total cost = $5.90
Unit rate = Total cost / green beans
= 5.90/10
= $0.59 per can
Therefore, the place with the best buy between village market and Sam's club is Sam's club at $0.59 per can.

Answer:
D. tan(-π/6)
Step-by-step explanation:
The tangent function is periodic with a period of π, so ...
tan(5π/6) = tan(5π/6 ± kπ) . . . for any integer k
For k = -1, we have ...
tan(5π/6) = tan(5π/6 -π) = tan(-π/6)
