An 85kg man stands on a scale inside an elevator. What is the weight in Newtons that the scale reads when the elevator is  a.  at rest?
b.  moving upward at a constant speed of 5m/s?
c.   moving downward at a constant speed of 8m/s?
d.  moving with an upward acceleration of 3 m/s2
e.  moving with a downward acceleration of 4 m/s2

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°

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

5 + 8 +7 + 4 + 0 +1 = 25
