Let me go ahead and help you start on these questions...
From the question we can see that we are talking about 2 jets, but we only are concerned with a single variable. Can you tell me the variable?
Let t = time that the plane was in flight...
I wish I was able to attach some pictures to the post to illustrate, but let me go ahead and explain the best I can with just writing.
Whenever we want to shift a function, in any direction, our goal is to manipulate the variable...
This question is testing whether you know and understand your trig tables. Here is our table:
Angle | Sin (Angle) | Cos(Angle) | Tan (Angle)
0 | ...
To start off, we have to determine how many equations we need to solve this problem. Seeing that the problem involves a "larger number" and a "smaller number" and that we are given 2 different constraints we can be assured that we will need 2 variables...
The first thing we can notice from this question is that we need two variables to write our system of equations(Ruth's age and the son's age).; this also means that we need two equations!
let R=Ruth's Age
let s= Ruth's...
Let me start by saying very interesting and "outside of the box" question. Although I don't think many can really give you a precise answer (including myself), I did find an interesting article that you may find interesting. Take a look at it and let me
So it turns out that there are really only 2 things that affect the velocity of a wave in a medium.
The medium's change in shape (elasticity)
The medium's change in motion (inertia)
This illustrates a pretty interesting concept of wave physics. Whether a turtle is crawling...
This is a really good question! Not only is it a favorite topic for the algebra regents, but it also tests how comprehensively we understand equations in math.
We have to start off by recalling to memory that a straight line (also called a linear equation)...
Jamila Q. gave an awesome response, however there may be another solution depending on your question. You see:
(5/6)t "which is what Jamila Q. solved" is very different than 5/(6t). If you notice, in the first expression t is in the numerator, which is what Jamila...
When you get problems like this, its great to start with a picture. I can't draw it here, but if you draw a giant circle, you can see that the diameter (length from one side of the circle to the other) in the middle of the circle is a LOT bigger than the
length of a line drawn...
