That's where I falter. I had 24x=6s. That's how I did the other problems.

I don't know. We've only done this kind of problem once before in class and I didn't understand it then. I could get the other stuff because it was geometry/algebra, but this part of the problem actually requires calculus, and at that, calculus I haven't done before. dx/dt= -5 ft/s 24d=6x...

yes, the point at which a solution freezes is defined as it's freezing point. That's what you asked.

You have to use the colligative properties. ΔTf = i Kf m http://www.chemistryexplained.com/Ce-Co/Colligative-Properties.html

Homework Statement A man 6 feet tall walks at a rate of 5 feet per second toward a streetlight that is 30 ft high. The man's 3 ft tall child follows at the same speed, but 10 feet behind the man. At times, the shadow behind the child is caused by the man, and at other times, by the child...

Are you disagreeing with me? I can't tell what point you're trying to get across. The limit of e^tan(x) as x approaches pi/2 from the right is zero.

The limit is zero. Actually, you can go to the table on your calculator (2nd, graph) and type in numbers that are extremely close and that will work. The limit is what it approaches, in this case from the right, and it's 0.
