Question 309849: Could you tell me if I did this problem right. Here is the word problem:
In a study of worker efficiency at Wong Laboratories it was found that the numer of components assembled per hour by the average worker t hours after starting work could be modeled by the formula
N(1) = -3t^3 + 23t^2 + 8t.
a) Rewrite the formula by factoring the right hand side completely.
b) Use the facored version of the formula to find N(3)
This is my solution:
a) N(t)=-3t^3+23t^2+8t
=-t(3t^2-23t-8)
=-t[(3t^2+t)-(24t-8)]
=-t[t(3t+1)-8(3t+1) ]
=-t(t-8)(3t+1)
b) N(3)=-3(3-8)(3×3+1)
=-3(-5)(10)
N(3)=150

Question 310316: A point on the outside of the axle of a truck has a circular motion that can be modelled by a sine curve.if you measure distance from the axle's centre to the bottom of the truck, that distance remains constant as long as the truck is on a level piece of road. if the truck goes over a bump, the springs absorb the shock but the truck bounces for a while. a truck is moving so that the axle, which is 6 cm in diameter, rotates at 1 rotation per second. as the truck hits a bump, the spring depresses by 20 cm and then continues to depress by 80% of the previous bounce as it bounces ever half second.
if the middle of the axle is 30 cm from the bottom of the truck, what is the equation that represents the distance from a point on the outside of the axle to the bottom of the truck
