A rectangle has a height of 5y^3 and a width of 3y^3-8y^2+2y.

Express the area of the entire rectangle.

Which expression do you get when you eliminate the negative exponents of 4a^2 b^216a^-3 b

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.
