From kindergarten through high school, the mathematics education in public schools in the United States has historically varied widely from state to state, and often even varies considerably within individual states. With the recent adoption of the Common Core Standards by 45 states, mathematics content across the country is moving into closer agreement for each grade level.
algebra 2 help...need it desperately
does anyone know algebra 2, i need to know how to complete this equation...
an expotential function of the form y=a(2)^x passes through the point (3,4). Find the value of a. choices a)2 b)1/2 c)3 d)3/4
I'm learning about imaginary numbers and radicals.
Here are the ones I need help with. Could someone explain how to do them, and what the answers are? Thanks
1. 2X + Yi = 3X + 1 + 3i (solve for X and Y)
2. (-4-5i)^2 (solve in a+bi form)
3. (1 - 2i)(-5 + 6i) (simplify in a +bi form)...

Hello! I was wondering how one knows that the tangent of 270 degrees is undefined without graphing it? I know tangent=opposite/hypotenuse, but how can you find the length of the opposite leg and hypotenuse? gah, I'm so confused.

Problem 51.
At a constant temperature, the atmospheric pressure p, in pascals, is given by the formula p=101.3e^-0.001h, where h is the altitude in meters. Find h when p is 74.3 pascals. Hint: Start by taking the natural logarithms of the expressions on each side of the equation.
