What is the period of the function y= cos(x/2) a. 2pi b. pi/4 c. pi d. 4pi

the period of sin and cos is

( 2* pi/ b ) where b is the number in front of x

period = (2 * pi)/( 1/2)

period = 4* pi

Choice D

answer is 33

step-by-step explanation:

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°
