The area under the given curve is 77/60. SO the option B is correct.
In the given question we have to estimate the area under the curve given the following fuction, interval, and number of subintervals using the right endpoint method.
The given function is
F(x) = 1/x; [1,5]; n=4
The given options are:
A≈77/240
A≈77/60
A≈77/15
A≈25/3
A≈25/12
Since, f(x) =1/x
∆x = (b-a)/n
∆x = (5-1)/4
∆x =4/4
∆x = 1
Now the table is
x 1 2 3 4 5
f(x) 1 1/2 1/3 1/4 1/5
R(4) = [f(2)+f(3)+f(4)+f(5)]∆x
R(4) = [1/2+1/3+1/4+1/5]1
R(4) = (30+20+15+12)/60
R(4) = 77/60
Hence, the area under the given curve is 77/60. SO the option B is correct.
