The graphs for this are very small, but I think the one that represents the solution is the third one, because with the x being 4 and the y being 0, that would make the point (4, 0) and satisfy the equation. With x being 0 and y being -2, the other point would be (0, -2). The graphs are too small to read, but whichever graph intersects over those two points I named is the answer.
1. They are all rational except √37 and √12.
2. B
3. square's side length = √(2^2 + 5^2) = √29
So side length is between 5 and 6.
Simplifying rational expressions will make the further calculations easier since the variables to work with will usually be smaller.
To determine that a rational expression is in simplest form we need to make sure that the numerator and the denominator have no common variables.
ANSWER
EXPLANATION
We use the sine rule to obtain,
We multiply both sides by 4 to obtain,
We take the inverse sine of both sides to get,
to the nearest tenth.
