There's no cube shown but we can guess the diagonal is the long diagonal.
In a rectangular parallelpiped (aka a box) with dimensions a × b × c the long diagonal x satifies a 3D version of the Pythagorean Theorem,
x² = a² + b² + c²
In a cube a=b=c
x² = 3a²
x = a√3
Answer: 7√3
Answer:
9.4 = x
Step-by-step explanation:
You are given the hypotenuse and the adjacent side, leading you to use cosine.
<u><em>Set it up:</em></u>
<u><em /></u>
<em><u>Multiply everything by 14, to remove it from the denominator:</u></em>
<em><u /></em>
<em><u>Multiply accordingly:</u></em>
9.36 = x
<em><u>Round to nearest tenth:</u></em>
9.4 = x
The y-intercept is (0, 2), because it's the spot where the line crosses the y-axis. The other point showed on the graph is the x-intercept..
