Q. Evaluate ∫06(10e−0.5x+4)dx and express the answer in simplest form.Answer:
Integrate first part: Now we will integrate the first part, ∫10e−0.5xdx. The integral of eax with respect to x is a1eax, so the integral of 10e−0.5x is: ∫10e−0.5xdx=−20e−0.5x
Integrate second part: Next, we integrate the second part, ∫4dx. The integral of a constant is just the constant times the variable, so: ∫4dx=4x
Combine integrals: Now we combine the two integrals to get the indefinite integral:∫(10e(−0.5x)+4)dx=−20e(−0.5x)+4x+CSince we are evaluating a definite integral from 0 to 6, we do not need to include the constant of integration C.
Evaluate at upper limit: We evaluate the indefinite integral at the upper limit of integration, x=6:−20e(−0.5×6)+4×6=−20e−3+24
Evaluate at lower limit: Next, we evaluate the indefinite integral at the lower limit of integration, x=0:−20e(−0.5⋅0)+4⋅0=−20e(0)+0=−20
Find definite integral: We subtract the value of the indefinite integral at the lower limit from the value at the upper limit to find the definite integral: (−20e−3+24)−(−20)=−20e−3+24+20
Simplify final answer: Now we simplify the expression to find the final answer: −20e−3+24+20=−e320+44
