Answer:
θ = π + periods of 2π
Sin (π + 2π) = 0
Cos (π + 2π) = -1
Tan (π + 2π) = 0
Step-by-step explanation:
Sin (θ)=0 implies that θ only can be 0 or π plus periods of 2π:
θ = 0+2π
θ = π+2π
For Cos(θ) the values only can be:
Cos (0+2π) = 1 and
Cos (π+2π) = -1
from this, only Cos (π+2π) < 0
So θ only can be θ=π+2π

Answer:There are two right triangles. You need to find the opposite side (the height) of each of them. The difference between the two is the height of the blade, x.
You know the adjacent, 440, and you are looking for the opposite, so you need to use tan for both.
tan (30) = y / 440
y = 440 * tan (30) = 254.034...
tan (38.8) = z / 440
y = 440 * tan (38.8) = 353.769.--
353.8 - 254.0 = 99.8 = 100 feet.
Step-by-step explanation:
I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
Answer:
NO
Step-by-step explanation:
- Try to replace x by -50
- y= 390 + 11*(-50) = -160
- in the table we have -210 so the table doesn't represent the equation
