The statement "cot theta= 12/5, sec theta = -13/5, and the terminal point determined by theta in quadrant 4"

1 answer:

5 0

If cot θ = 12/5, then tan θ = 5/12.
If sec θ = -13/5, then cos θ = -5/13

For tan θ to be positive while cos θ is negative, the quadrant is 3.
The figure below shows θ graphed as a reference angle in quadrant 3.

Answer:
The statement that θ is in quadrant 4 is FALSE.

muminat

The range of a function is the set of y-coordinates of all the points int he graph of the function.
Look at the graph. The vertex is point (2, -3).
The graph does not go lower than that point.
The lowest y-coordinate is -3.
The graph goes up forever on both sides until infinity.
The range is all numbers greater than or equal to -3.
