IDK how to solve this. This is on a quiz Please explain how you solve this.
I did find the degree of cosθ and I got 143 degrees. That is in the second quadrant so I do think this quiz has a typo in it too.

1. Given: cosθ = -4/5, sin x = -12/13, θ is in the third quadrant, and x is in the fourth quadrant; evaluate sin.
A. -3/5
B. -3/4
C. 3/5

Which of the following shows the graph of y=2e^x?

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour.valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house.which graph correctly represents valerie's distance from her house after her coffee break?
