At which point(s) do the graphs of y = x + 1 and y = 2x intersect?

Write a function for a rotation 90 degrees counter clockwise about the origin, point 0

The function models the number of accidents per 50 million miles driven as a function

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.
