simplify: (sinx/cosx)-1/(cosx/sinx)-1

Find the domain of the function p(x) =x^2-2x +3

collect like terms 15a + 3b - 9a -7b I come up with 6a + 106 but it just dosen't look right.

The function H described by H(x)=2.75x + 71.48 can be used to predict the height, in centimeters, of a woman whose humerus (the bone from the elbow to the shoulder) is x cm long. Predict the height of a woman whose humerus is 38 cm long?

decide whether the pair of lines are parallel, perpendicular or neither? 2x + 3y =6 2x + 3y = 4

Use the distributive property to solve the equation. 8(w-4)=-32 W= This is how I did it, I don't think it is right. 8(w-4)=-32 8w - 8*4 = -32 w = -24

A 10 charge sits at a point in space where the magnitude of the electric field is 1900 .What will the magnitude of the field be if the 10 charge is replaced by a 20 charge?

You are pulling a 60-kg crate across a level floor with a rope. If a force of 200 N on the rope gives the crate an acceleration of 2 m/s2, what is the force of friction that the crate exerts on the floor?

Two ideal gases have the same mass density and the same absolute pressure. One of the gases is helium (He), and its temperature is 298 K. The other gas is neon (Ne). What is the temperature of the neon?

Which results in a higher force of impact? Assume both collisions are completely inelastic (your car comes to a stop) and both take the same amount of time. A) Running your car at 20 mph into a solid wall B) Running your car head-on at 20 mph into an iden...

Two identical point charges (q = 7.20 x 10^6 C) are fixed at diagonally opposite corners of a square with sides of length 0.480 m. A test charge (q0 = 2.40 x 10^8 C), with a mass of 6.60  108 kg, is released from rest at one of the empty corners...
