Draw the image of ∆pqr after a rotation of 180° about the origin. label the image ∆p'q'r'. draw the image of ∆pqr after a reflection across the x-axis. label the image ∆p"q"r".

What are the values of each variable in the diagram below?

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.

Why is it so easy to buy on impulse and overspend with a credit card? what could you do to counteract this tendency?
