Answer:
Great work!
Step-by-step explanation:
These kind of questions are calculated through Riemann Sum. You can evaluate any definite integral using the Riemann Sum. It should be in the following form:
f(x)dx on the interval [a, b], or

Now f(x) is simply y. Therefore in this example y = x^3 - 6x. We just need the sufficient amount of data to apply the Riemann Sum, including the interval [a, b] that bounds the area, and the the number of rectangles 'n' that we need to use.

Answer:
Step-by-step explanation:
22 liters of petrol to travel 259.6 km
1litres will travel 259.6/22 km
1litres will travel 11.8km
:2013.2km needs 2013.2/11.8litre
:2013.2km needs 170.61litres
And 1 liter of petrol costs $ 1.99
So 742.88 litres will cost $1.99×170.61
= $339.51
