Answer:
Her friend is correct
Step-by-step explanation:
40 * 20% = 8
40+8=48
(-5, 12). Cosecant is the reciprocal of sine. Since csc theta =13/12, sin theta=12/13. We can narrow down to two angles, one in first quadrant and one in second quadrant. We are also given sec theta=-13/5, so cos theta=-5/13. Thus the angle is in the second quadrant. tan theta=1/cot theta=-12/5, so point (-5, 12) is on the ray.
I think it’s positive. As it gets heavier, the cost has a positive slope, or increases. I’m not absolutely sure though
