Answer:
vertical
Step-by-step explanation:
just need yo imagine
Arctan (√3 /3) = 30°. = π/6 rad
That is the value searched, in degrees and radians.
You can verifiy that tan(30°) = sin(30°) / cos(30°) = [1/2] / [√3/2] = 1/√3 = √3 / 3
Answer:
C) 18 cents
Step-by-step explanation:
Given,
This weeks deal -
Quantity of Flour Price ($) Price per pound ($)
3 pounds 5.25 (5.25/3) = 1.75
5 pounds 9.75 (9.75/3) = 1.95
7 pounds 12.60 (12.60/3) = 1.80
10 pounds 14.20 (14.20/3) = 1.42
12 pounds 18.24 (18.24/3) = 1.52
The lowest price per pound is $1.42. Therefore, this is the current week's best deal.
The last week's best deal was = $`1.60/pound
The difference between the unit price for previous week's best deal and this week's best deal = $1.60 - $1.42 = $0.18
Therefore, 18 cents.
Plug in 12 for y and rewrite the equation.
12 = 4x + 4
Subtract 4 from both sides.
8 = 4x
Divide by 4 on both sides.
2 = x
The ordered pair is (2, 12) and x = 2.
