Which operation should you perform first when evaluating the expression: 3 to the power of 2+2

Find the slope of the line that contains the following points. r(-2, 4), s(6, -2)

Need this asap if anyone can i would be very grateful. if you could show workings that would really

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.
