f(x) = 2 - e ^ (x / 2)

isn't domain usually (-oo, oo) ?
how do you find range? do i need to set it up as an inequality where its ">0" ? steps and an explanation would be helpful. thanks for your help.

I don't necessarily need the answer, but I just need to know how to find the answer here.

A car is traveling on a curve that forms a circular arc. The force F needed to keep the car from skidding is jointly proportional to the weight w of the car and the square of its speed s, and is inversely proportional to the radius r of the curve.

A car weighing 1600 lb travels around a curve at 60 mi/h. The next car to round this curve weighs 2500 lb and requires the same force as the first car to keep from skidding. How fast is the second car traveling?

Acceleration = final velocity – initial velocity / elapsed time between two measurements

So: 91.5 – 0 / ????

What times do I subtract?

Data table for ball rolling down 10 degree incline lab:
Distance Time
91.50 1.16
76.25 1.12
61.00 .99
45.75 .83
30.50 .72
15.25 .53

I know velocity is d/t. Which numbers do I plug in where, to find acceleration? I tried and the numbers I got don’t match the scale for the graph at all. *See previous questions for more.
I don't know what to plug in where.
The lab was an inclined plane at 10 degrees with six sections marked off. We rolled the ball from each section until the end, timing it (from 15.25 cm, to the end, 0). Help...

We assume that Y is a non-empty set and we say that ~ be an equivalence relation on Y. We let W be the set of distinct equivalence classes given by ~. prove that elements of W are disjoint and their union is all of Y.

please help. thank you.

At least some of them (animals), have blubber to protect their
insides---but their eyes are right up against the water. Do they
have a retractable lid of some sort?

What is an Hypothesis? I know the answer because I have taken the time to look it up on dictionary.com, merriamwebster, wikipedia, answers, google, yahoo, and ask.com. So please NO COPY & PASTE. Cause not only will I make sure your answer is taken off, you will not get a chance at that great 10 pts for best answer.

My question goes: Does a hypothesis have to be an if-then statement? Please give a VERY good reason for why or why not. If possible, give as many examples/details as possible, these help me in deciding who should get best answer award.
Copy&paste=0pts Hardwork=10pts Knowing you've made someones day, priceless.
