A Flat Metal Plate Is in the Shape Determined by the Area

question 13

Short Answer

A flat metal plate is in the shape determined by the area under the graph of $f(x)=\frac{1}{1+x}$ between x = 0 and x = 4.The density of the plate x units from the y-axis is given by x² grams/cm².Write down a Riemann sum which approximates the total mass.Convert it to an integral, and evaluate the integral to 3 decimal places.
