Answer:
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Step-by-step explanation:
use the formula an=a1rⁿ⁻¹
aⁿ=4(−1)ⁿ⁻¹/3ⁿ
Answer:
The correct answer is second quadrant.
Step-by-step explanation:
Vertices of J ≡ (3 , -5) which shows J is in fourth quadrant. When J is reflected across the line y = -1, the point J moves to first quadrant as J' with coordinates (3 , 3).
Vertices of K ≡ (-8 , -1) which shows K is in third quadrant. When K is reflected across the line y = -1, the point K remains where it is (in the third quadrant) as it is on the line y = -1 only.
Vertices of L ≡ (5 , 1) which shows L is in first quadrant. When L is reflected across the line y = -1, the point L moves to fourth quadrant as L' with coordinates (5 , -3).
Thus each of the first, fourth and third quadrant contains a vertex except the second quadrant.
If there were two electricians, they'd need to install 48 fixtures per person.. if it takes 20 minutes for each fixture, it would take a total of 960 minutes, which converts to 16 hours. If a work day was only 8 hours, it would take two electricians TWO work days to install 96 light fixtures, or 24 light fixtures for four floors.
For this case we must solve the following equations:
We subtract 3x on both sides of the equation:
We subtract 7 on both sides of the equation:
We divide between 2 on both sides of the equation:
The second equation is:
We apply distributive property to the terms of parentheses:
We add common terms:
We add 10 to both sides of the equation:
We divide between 5 on both sides of the equation:
Third equation:
We apply distributive property to the terms within parentheses:
We add similar terms:
We subtract 6x on both sides of the equation:
We subtract 5 on both sides of the equation:
