Part A Let's do this step-by-step. Since she first deducts $10, the total price of the dress is now just $50. Then, she applies the 30% discount which is: Subtract 15 from 50 to get $35. $35 is the total cost she ends up paying.
Part B Let's also do this. 30% off of $60 is: Subtract 18 from 60 to get $42. Then, since she applies the $10 discount, let's subtract $10 from $42 to get $32. She ends up paying $3 less dollars if the cashier puts the 30% off discount before the $10 off discount.
Distance = the square root of (x2-x1)2 + (y2-y1)2Added:Distance Formula: Given the two points (x1, y1) and (x2, y2), the distance between these points is given by the formula:square root of x2-x1 squared +y2-y1 squared
The <em>composition</em> of the <em>functions</em> f and g represented by g ∘ f ( 0 ) means that g is applied to f(0), i.e f(0) is the input to the function g.
