Answer:

11/4

Step-by-step explanation:

To find the slope of a line given two points, we use the formula

m = (y2-y1)/(x2-x1)

   = (-10-12)/(-7-1)

  =-22/-8

  =11/4

DerKrebs [107]

cos(A - B) = cos A cos B + sin A sin B

In this case, A is \frac{\pi }{3} and B is \frac{\pi }{5}, so:

  cos\frac{\pi}{3} cos\frac{\pi}{5} +sin\frac{\pi }{3} sin\frac{\pi }{5} =cos(\frac{\pi}{3} -\frac{\pi}{5} ) = cos\frac{2\pi}{15}

Hope that helps!
