Hello, can someone help me solve this problem? I tried working it around but I can't arrive at the correct answer. Thank you!
Problem: Find the equation of the curve for which y''=12/x3 if it passes through (1,0) and is tangent to the line 6x+y=6 at that point.
Answer: xy+6x=6

I've got this Situation in our trigonometry class and i'm a bit confused.. Here is the math problem: A pulley of radius 6 inches drives a machine by a belt. If the pulley is turning at 300 rev/min, what is the velocity of the belt in feet per minute? Kindly answer with solution, please..
Problem 604
Determine the magnitude of the resultant, its pointing, and its direction cosines for the following system of non-coplanar concurrent forces. 200 lb (4, 5, –3); 400 lb (–6, 4, –5); 300 lb, (4, –2, –3).
