4. The coordinates below represent a triangle that was dilated.
J(-3,-12) ► J'(-2,-8)
K(-6, -15) ► K'(-4,-10)
L(-9, -12) → L'(-6,-8)
What was the scale factor that was used in the
dilation?

Which of the following is correct interpretation of the expression -4+13

In the triangles, tr = ge and sr = fe. if = 3.2 ft, which is a possible measure of ? 1.6 ft 3.0 ft 3.2 ft 4.0 ft

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.
