Fine increase = 78 - 65 = 13
Increase rate = 13/65 x 100% = 20%
Discounted amount = 560 - 476 = 84
Discount rate = 84 / 560 x 100% = 15%
Step-by-step explanation:
Here, x cancels each others
Moving from a to b, the x component of the desired vector is 7-(-9) = 16, and
the y component is 3-9 = -6.
So the vector from a to b is <16,-6>, and the magnitude is
sqrt(16^2 + (-6)^2 ), applying the Pythagorean Theorem.
