Answer:
The equation should look something like this.
Be careful with your use between cubing and multiplying; Cubing is multiplying the number by itself multiple times, while multiplying is like repeated adding, yet much easier.
In this case, if it says triple, I highly recommend multiplying by 3, which is what I did, it only looks different because it is in parentheses.
What have we learned?
<h3>We learned how to write algebraic equations, and some further information on multiplying.</h3>
Step-by-step explanation:
The solution can be found by identifying the point of intersection of the 2 graphed lines.
As we can see, they intersect each other at the point (2, -3). This is our solution for the equations.
Answer:
x ≈ 46.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = 
= 
= 
, then
x = 
( ) ≈ 46.7° ( to the nearest tenth )
Answer:
B
Step-by-step explanation:
For cartesian to polar transformation,
x = rcosA , y = rsinA.
Put in the values in the given equation. And (cosA)^2 - (sinA)^2 = cos(2A)
