The temperature on mars may reach a high of 79 degrees at the equator in the summer it may reach a low of -225 degrees at the poles write an expression that will give you the difference

Two lines that do not intersect are skew. always sometimes or never

Simplify the expression. -2/5(10+15m-20n)

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.
