Abarrel shaped like a cylinder is laid on its side and rolled up a ramp that is
180ft long. the barrel has a circular base that turns 45 times in being rolled up the ramp. what is the diameter of the circular base?

Matt and brian were solving a system of equations. they both noticed that the two lines had the same slope. brian said that because each line in the system had the same slope, the two lines had to be parallel, which meant the solution to the system was "no solution" matt disagreed, and said they should also look at the y-intercepts before determining how many solutions there were. who is correct?

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

Select the conic section that represents the equation. 3x2 + 3y2 -2x + 4 = 0
