How can this be accomplished when you can't divide by 0? Does the negative twelve make a difference?

1. Find the points P and Q on the parabola y=1-x^2 so that the triangle ABC formed by the x-axis and the tangent lines at P and Q is an equilateral triangle.

2. Find the point where the curves y=x^3-3x+4 and y=3(x^2-x) are tangent to each other, that is, have a common tangent line.

3.A car is traveling at night along a highway shaped like a parabola with its vertex at the origin. The car starts at a point 100 m west and 100 m north of the origin and travels in an easterly direction. There is a statue located 100 m east and 50 m north of the origin. At what point on the highway will the car's headlights illuminate the statue?

4. Use linear approximation (or differentials) to extimate the given number:
sin(1 degree)

Answers to all or any of the questions would be great! Thanks!!!!

Find the equation of the plane through point (-1, 4, 2) that contains the line of intersection of the planes:
4x - y + z - 2 = 0 and
2x + y - 2z - 3 = 0

By making y = t, I found the intersecting line equation to be:
x = 7/10 + 1/10 t
y = t
z = -4/5 + 3/5 t.

So this direction is <1/10, 1, 3/5>

Where do I go from here? The answer in the back of the book is:
4x - 13y + 21z + 14 = 0

I'd appreciate any help.

I've got what I hope is a basic probability question...in a nutshell:

Assume that an event will only occur if three conditions are met. Each condition has an individual probability of occuring...for the sake of argument, condition 1 has a 1 in 5 chance, condition 2 has a 1 in 10 chance, and condition 3 has a 1 in 20 chance.

Using the individual probabilities, how do you determine the probability of the event occuring?

Differentiate the following function. y=5e^x+2...

i thought it would be e^x since the 2 becomes zero and the five i thought went away but thats not right.
