Use numerals instead of words. If necessary, use / for the fraction bar(s). A parabola is given by the equation y = x2 + 4x + 4.
The vertex of the parabola is -2,0 . The focus of the parabola is . The directrix of the parabola is given by the equation y = . Note: Separate coordinates inside parentheses with a comma.
The statement above is true. Polar equations indeed can describe graphs as functions, even if when the equations in the rectangular coordinate system are not one of the functions. Polar equations can be graphed accurately using hands by using the Polar Coordinate System.
The profit he made from selling his hearing aids at a profit of 17% is $234.26.
<h3>How to calculate the profit obtained?</h3>
To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.
$1,378 ÷ 100 = $13.78
$13.78 × 17 = $234.26
Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the finalsaleprice of the earphone, we add the initialvalue plus the value of the profit.
