Multiply r^2+7r+10/3 by 3r-30/r^2-5r-50

The larger of two number is 4 less than twice the smaller number. the sum is 41. find the numbers

What is the slope of the line that contains the points (-2,1) and (0,-3)

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
