If 5k = -25, then 5k - 1 = -25 - 1
Segment proof

Evaluate the expression for the given value of the variable. 5×(h+3) for h=7

What is the frequency of the sinusoidal graph?

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.
