What does a rational number look like?
It looks like a ratio of two integers, p/q, where q is not zero.
Does the letter Q have a line of symmetry?
Yes, the letter Q does have a line of symmetry. A line of symmetry is a line that divides a shape into two equal parts that are mirror images of each other. In the case of the letter Q, a vertical line passing through the center of the letter would create two equal and symmetrical halves.
What is a local minimum point?
A function has a "local minimum point" at a point p where there exists at least one positive number e having the property that the value v of the function for any point q for which the absolute value of q - p is greater than 0 but not greater than e, the value of the function at q is greater than or equal to the value at p.
Why is a question mark shaped like this?
It's because back then there were no punctuation marks so when people wrote a question they would put the letters "Q" "O" at the end of a question when they wrote letters or stories. So it would look like this: What's for dinnerQO But when people got the letters, they thought "Q" "O" were apart of the sentence, so then people started writing the "Q" over the "O". Then after time people became lazy writing "Q" and "O", so then as time went by, the "Q" became eroded and was drawn halfway, and the "O" became a tiny little dot.
How do you find the coordinates of a quadrilateral after reflecting it over the y axis?
If the coordinates of a point, before reflection, were (p, q) then after reflection, they will be (-p, q).
