Three points of a function are graphed. Which statement describes the function through the points?

- The function is a direct variation function with a constar of variation of 1.5

- The function is a direct variation function with a constar of variation of 18

- The function is inear but is not a direct variation function

- The function is not a linear function

Evaluate cos2θ for cosθ = square root of 3/2

On a cm grid, point p has coordinates (3,-1) and point q has coordinates (-5,6) calculate the shortest distance between p and q give your answer to 1 decimal place

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.
