Answer:
270 more pizza lunches were sold.
Step-by-step explanation:
40 x 450 = 18,000
18,000 / 100 = 180
180 - 450 = 270
Answer:
Cos(2115°) =1/√2
Sin(2115°) = -1/√2
Step-by-step explanation:
We have to find the values of Cos (2115°) and Sin (2115°).
Now, 2115° can be written as (23×90°+ 45°).
Therefore, the angle 2115° lies in the 4th quadrant where Cos values are positive and Sin values are negative.
Hence, Cos (2115°) = Cos(23×90° +45°) =Sin 45° {Since 23 is an odd number, so the CosФ sign will be changed to SinФ} =1/√2 (Answer)
Again, Sin (2115°) = Sin(23×90° +45°) = -Cos 45° {Since 23 is an odd number, so the SinФ sign will be changed to CosФ} = -1/√2 (Answer)
Now, the required reference angle is 45°. (Answer)

hope it helped ! :)
Anything what i can do for you?
The first thing to do in this case is to graph both equations
y = 2x +1
y = / x /
Once graphed, you must evaluate points in the Cartesian plane that satisfy the inequations to know where the solution set is.
For this case, the solution set is in the shaded region, or equivalently, quadrants 1 and 2.
answer quadrants 1 and 2.
