Profit, P, is the difference between revenue, R, and cost, C, so P = R - C. Which expression represents P, if R =2x^4 -3x^3 +2x -1 and C= x^4-x^2+2x+3

Describe the relationship between the angles of similar triangles and the sides of similar triangles

Suppose your school costs for this term were $4900 and financial aid covered 3/4 of that amount. how much did financial aid cover? and how much do you still have to pay?

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.
