Final answer:

The centroid of the region bounded by y = e^x, y = 0, x = 0, x = 5 is (2, 2e).

Step-by-step explanation:

The centroid of a region bounded by curves can be found by using the formula for the x-coordinate of the centroid:

x = (1/A) ∫[a,b] x f(x) dx

In this case, the region is bounded by y = e^x, y = 0, x = 0, and x = 5.

To find the centroid, we need to find the area of the region, A, and the integral of x times the curve function, f(x).

The area can be found by:

A = ∫[a,b] f(x) dx

For this region, the area is:

A = ∫[0,5] e^x dx

The integral of x times the curve function is:

∫[a,b] x f(x) dx = ∫[0,5] x e^x dx

Using these values, we can find the x-coordinate of the centroid:

x= (1/A) ∫[0,5] x e^x dx

After calculating the values of A and we get the centroid coordinates as (2, 2e).
