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 3. The sum of the two numbers is 3 and the sum of their reciprocas is 12/5. Find the numbers. Problem 7. What is the linear term of the equation q = 3x^2 + 2x - 1? Problem 9. Write the equation of the ellipse with foci at (12,1) and (-12,1) and the endpoints of the major axis...

Problem 43. Solve and check. 7^3x divided by 2^7x-1 = (43.2)^x+2

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. Solve and...
