Graph the pair of parametric equations. x=7sint+sin7t, y=7cost+cos7t

a is the correct

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

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°
