The equation of a circle is x^2+y^2+6x-2y-15=0. find the center and radius of the circle.

Simplify.7x + 3y - 2 + 6x + 1 + y squared 2 you! ; )

Ateacher noticed 5/8 of the students were wearing either blue shorts or white shorts. write two different ways this could be done.

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.
