Solve the equation for Theta, (0 ≤ Theta < 2pi).

cos theta/2 - cos theta = 1

Let r represent the radius of the circle, X the central angle (measured in radians), and s the length of the arc are subtended by the angle. Use the relationship s = rX to complete the table.

This is so confusing. Any help would be appreciated.

A car is moving at the rate of 50 miles per hour, and the diameter of its wheel is 2.5 feet.

A) Find the number of revolutions per minute that the wheels are rotating.

B) Find the angular speed of the wheels in radians per minute.

If r sub1, r sub2, r sub3, r sub4 are roots of x^4 - 4x^2 + 2 = 0, what is the value of (1+r sub1)(1+r sub2)(1+r sub3)(1+r sub4)?

What is the smallest positive integer c for which (sq. root of a) + (sq. root of b) = (sq. root of c) has a solution in unequal positive integers?

What are all the ordered pairs on integers (a,b), with 0<a<b, for which (a root 2007) (b root 2007) = (9 root 2007)?

(I don't mean 9 times sq root of 2007. It's square root of 2007 with a little a,b, or 9 on the left side inside the v part of the sq. root symbol. What is that called? Any help would be appreciated, thanks.)

For any integer k > 1, k!, is the product of every integer from 1 to k. Thus, 3! = 1 x 2 x 3. What's the only integer n>32 that satisfies (n-23)!(23)! = (n-32)!(32)! ? Any help would be appreciated, thanks.

It can be proved that there is only one positive integer for n for which both n and n^2 + 2 are prime. What is the unique value of n? Any help would be appreciated, thanks.

A function f will be called repetitive if there are at least two different values of x in the interval 0 ≤ x ≤ 1 for which f(x) has the same value. What are all real numbers b for which f(x) = x^2 +bx + 3 is repetitive? Any help is appreciated, thanks.

As my younger brother shouted out four consecutive inegers, I divided each by my age (an integer), then added all four remainders to get 40. As he shouted out four other consecutive integers, I divided each by his age (a different integer), added all four remainders, and again got 40. What is the sum of our ages? Any help would be appreciated. Seems sorta easy but I can't figure out a working formula.

In convex quadrilateral ABCD, the area of triangle ABC is 3, the area of triangle CDA is 4, and the area of triangle DAB is 5. What is the area of triangle BCD? I got 5 after drawing it. Any help would be appreciated, thanks.

If a,b, and c are real numbers, what is the only value of a for which the graphs of y = ax+b and x=ay+c are perpendicular to each other?

Our design team drew all 48 line segment that connect 6 points on one side of rectangle R to 8 points on the opposite side. In at most how many different points inside R can those 48 line segments intersect?

In my truck, I'm moving a rectangular solid whose volume is 105. If the length of each edge is a prime, what is the total surface area (the sum of the areas of all 6 faces) of the rectangular solid?

For how many different positive integers n does (sq. root of n) differ from (sq. root of 100) by less than 1?

For what rational number c do the equations

x^3 + cx^2 + 3 = 0 and x^2 + cx + 1 = 0 have a common solution?

If the length of the sides of a right triangle are the square roots of three consecutive integers, what is the sum of those three integers? Any help would be appreciated.
