Answer:
1/2
Step-by-step explanation:
x = t² + 2t
dx/dt = 2t + 2
y = t² + 1
dy/dt = 2t
dy/dx = (dy/dt) / (dx/dt)
dy/dx = 2t / (2t + 2)
dy/dx = t / (t + 1)
At t = 1, dy/dx = 1/2.
Answer:
60 boxes
Step-by-step explanation:
180 pounds plus 20 pounds is 200 pounds, which means that the weight of the boxes can't be any more than 1800 pounds (2000 - 200 = 1800). Divide 1800 by 30 (weight of one box) and you'll get 60 boxes
