### Subject: SAT II Mathematics Level 2

What is the distance in space between the points with coordinates left parenthesis (-3, 6, 7) and (2, -1, 4)

distance=rad((x2-x1)^2+(y2-y1)^2+(z2-z1)^2) so, plug in the numbers d=rad(((-3)-2)^2+(6-(-1))^2+(7-4)^2)=rad83=9.11

### Subject: College Admissions

The age-old question: how much does testing actually matter in college decisions?

Think of it like a benchmark for admissions officers, not a way to measure you up against others. They will not narrow down to 2 candidates and choose one or the other based off of one score. Rather, it is a means to put you in a group of qualified candidates to evaluate. Keep in mind that testing is only 1 piece of your application and they will view it as a whole.

### Subject: Calculus

How does a first-order derivative describe the nature of a function?

To answer that, one must understand how a first-order derivative relates to its function. The derivative is "derived" from the original function, resulting in a new expression. That expression shows HOW MUCH a function is changing at a particular point. For example, on flat ground, the derivative of you moving upwards is 0. However, if you were to walk up a hill, the derivative of you moving upwards would be greater than 0.
