y' = 
, by the Fundamental Theorem of Calculus
y'' = 
, which has a denominator that is always positive. The numerator

Answer:
58×.20=11.60 58.00+11.60= 69.60 your total cost is 69.60 to leave your tip on top of the bill
Step-by-step explanation:
any time you want a percentage of a number you take your number in this case 58.00 times whatever percentage in this case 20% so 58×.20 =11.60 then you take your total plus the amount you come up with for the tip 58.00+11.60=69.60
Use the equation y2-y1/x2-x1 then simplify
