A typical graphing calculator has a height-to-width ratio of 23.
Is it square? Yes Explanation: See solution.
A typical graphing calculator has a height-to-width ratio of 23. Therefore, the graphing calculator will display a square window if the height and width satisfy this ratio.
Height/Width=2/3
Let's find the height (y) and width (x) of the given viewing window.
Height:& 8-(-2)=10
Width:& 8-(-7)=15
Now we can use our formula.
