What number that you can multiple by 7 that will give you 7/10​

Which of the following points is collinear with (-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.

Find the measure of angle y. a. 115° b. 65° c. 43° d. 22°
