Answer:
b.
Explanation:
Before we begin, remember that:
tan α =
Now for the given, we have:
cos θ - tan θ * cos θ = 0
cos θ -
* cos θ = 0
cos θ - sin θ = 0cos θ = sin θ
Now, divide both sides by cos θ, we get:
1 = tan θ
Following the ASTC rule, we know that the tan function is positive in the first and third quadrants.
This means that:
either θ =
or θ = π +
=
Hope this helps :)
Answer:
540 m
Step-by-step explanation:
We are given that
Central angle,rad
Radius of circle=18 m
We have to find the length of the arc s.
We know that
Length of arc,
Using the formula then, we get
Length of arc,
Hence, the length of arc=540 m
9514 1404 393
Answer:

Step-by-step explanation:
(a) The graph is scaled by a factor of 2, and shifted up 1 unit. The scaling moves each point away from the x-axis by a factor of 2. The points on the x-axis stay there. The translation moves that scaled figure up 1 unit.
__
(b) The graph is reflected across the x-axis and shifted right 4 units. The point on the x-axis stays on the x-axis.
Answer:
yes
