Suppose a triangle with the vertices (–1, 4), (–1, –2), and (2, –2) were dilated, with the center of dilation at the origin and with a scale factor of 2. Which of these would be a vertex of the dilated figure? Select three that apply. Lector inmersivo
(-2, -4)
(-2, 8)
(-1, -4)
(-1, 4)
(4, -4)
(4, -2)

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.
