The inequality x2 + 12x + 35 ≥ 0 has two critical points and three possible intervals for solutions. choose each set of possible test points for the three intervals.
–8, –6, –4
–10, –6, 0
–6, 0, 6
–6, 0, 10

–8, –6, –4

-10, –6, 0

Step-by-step explanation:

a & b are the correct answers

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°
