First thing I'd do is check if it CAN be factored, by checking the discriminant b^2 - 4ac, the thing that appears in the quadratic formula under a square root sign. If that's not a perfect square, then you can't factor it. b^2 - 4ac = 7^2 - 4*2*(…

It is incorrect that "to" is only used for verb infinitives. It has many uses. "I am going to school". "School" is not a verb. In this case the expression "to be used to" which means "to be accustomed…

The derivative of v^2 with respect to x is 2v dv/dx by the chain rule. So the derivative of 0.5v^2 with respect to x is v dv/dx. I'm not sure what the rest of your question is. Why is that equal to dv/dt? It's not in general. Perhaps you were to…

You're integrating m^-1, so the y axis is actually the "x" row. Heights of rectangles will be those values. The x axis is the "m(x)" row. Perhaps it would help to write g(x) next to the first row and x next to the second row. …

"From a point 40 m away from the base of a flagpole" That's the adjacent of the angle "the angle of elevation of the top is 28º." That's the angle. "Determine the height of the flagpole." That's the opposite of…

Yes, just swipe it each time you enter a bus. I had to look up the silly "TrailPass/TransPass" terminology to figure out what that meant. I live in Zone 2 and buy weekly and monthly passes, but I just ask for a "Zone 2 weekly"…

The slope is the coefficient of x. Where is the x? What is its coefficient? The y-intercept is the constant term, the one with no x. Where is that term? What is its value?

The slope is (change in y) / (change in x) but the change in x is 0, so this would be an infinite slope, meaning a vertical line. So the equation is of the form x = constant. Look at the points to see what constant the x value is.

It has a magnetic moment, but that's not typically how it is detected. This Wikipedia article covers the bases http://en.wikipedia.org/wiki/Neutron_detection The basic answer is "indirectly", for instance by noticing that something unc…

I'll bet you've been given some formulas relevant to satellites. What are they? You can derive them from Newton's law of gravity, so I'll start there. But as I say, I'll bet you already have this derivation or something like it in your notes. …

-33pi = -32pi - pi You can ignore multiples of 2pi like -32pi, since they don't change the value. cos(-33pi) = cos(-pi) NOW do you know why it's -1? -pi is -180 degrees.

Yes, that is due to parallax. As you move, the direction to closer objects changes faster than the direction to farther objects. Measuring how much the nearby objects shift is exactly how the distance is determined. Look at the animation here …
