Answers by Tristan N.

Hello Nikki!   I'm not sure what "the five-step problem-solving approach" is, but I can tell you that the best way to solve this - or any - word problem is to deconstruct it into a series of equations that can be manipulated more easily. Let's analyze the question:   "A...

The "bearing" means angle relative to North. Imagine a line linking R and B (from now on, I will call it RB). The angle between that RB and "north" is the bearing, which is 120 degrees. Now consider the information they give you: "The North/South lines at R and B are parallel...

Greetings Alice! The objective here is to calculate what value of x for which that statement is true. X itself is just a variable which cab take on any value we need it to but may not necessarily result in the right answer. Case in point, let's pick a value at random: 20. If X were 20 then...

Greetings Milena! The first thing you should do is to solve for sinx: sinx = sqrt(2)/2 Now, to solve x, I am sorry to have to tell you that without a calculator, the only real way to solve this is by knowing the unit circle and its values. In this case x would have to equal 45 degrees,...

cot^2x+cscx-1=0 (answer)

The first step is to use trigonometric identities to simplify this expression. One of the most basic trig identities you will ever need to memorize is: sin^2x + cos^2x = 1 Now, we can manipulate this to find a way to simplify cot^2x by dividing both sides by sin^2x to get this: sin^2x/sin^2x...

Greetings Alexis! Any time you encounter absolute values, that is short hand for saying you have a piece-wise function, or two functions put together. In essence, the function you've been given is shorthand for: f(x) = -(x+1) = -x-1 for x+1<0 --> x<-1 AND f(x)...
