Q. Evaluate ∫06(3e0.5x−2x)dx and express the answer in simplest form.Answer:
Identify Integral: Identify the integral to be evaluated.We need to evaluate the integral of the function 3e0.5x−2x with respect to x from 0 to 6.The integral is written as ∫06(3e0.5x−2x)dx.
Break into Two: Break the integral into two separate integrals.We can separate the integral into two parts: one for 3e0.5x and one for −2x.So, ∫06(3e0.5x−2x)dx=∫063e0.5xdx−∫062xdx.
Evaluate First Integral: Evaluate the first integral ∫063e(0.5x)dx. To integrate 3e(0.5x), we use the fact that the integral of e(ax) is (1/a)e(ax). Thus, the integral of 3e(0.5x) is (3/(0.5))e(0.5x)=6e(0.5x). Evaluating from 0 to 6 gives us 6e(0.5⋅6)−6e(0.5⋅0).
Evaluate Second Integral: Evaluate the second integral ∫062xdx. The integral of 2x with respect to x is x2. Evaluating from 0 to 6 gives us 62−02=36−0=36.
Combine Results: Combine the results from Step 3 and Step 4.We have 6e0.5×6−6e0.5×0−36.Now we need to calculate the values of e0.5×6 and e0.5×0.e0.5×6=e3 and e0.5×0=e0=1.So, the result is 6e3−6(1)−36.
Simplify Expression: Simplify the expression. 6e3−6−36=6e3−42. This is the final value of the definite integral.
