We are given with the sequence -20, -16, -12, -8. From this sequence, we can see that the arithmetic difference is +4, from -(-20 + 16). hence following the arithmetic formula of an = a1 + d *(n-1). Substituting, an = -20 + 4 *(n-1) where n is an integer
Answer:
1. the square root of 89 or 9.4
2. the square root of 197 or 14.0
Answer:
180 cubic millimeters
Step-by-step explanation:
The volume of a hexagonal prism can be found with the following formula:
The area of a hexagon is:
Upon, closer inspection, you'll notice that the formula for area of a hexagon is in the formula for volume of a hexagonal prism.
We already know the area of the hexagon base, so we can just plug it in into the volume formula.
V=30h
We ale aso know the height, which we can plug in.
V=30(6)
Simplify.
V=180
The angle with the largest measure is opposite the longest side. The longest side is 12. It is opposite angle B. The appropriate choice is ...
B. ∠B
