Evaluate the integral using integration by parts with the indicated choices of u and dv. (Use C for the constant of integration.) xe9x dx; u

Answers

Answer:

The answer is "[tex]\bold{\frac{ \ e^{9x}}{9} (x-1)+C}\\[/tex]"

Step-by-step explanation:

Taking the integral [tex]\int x^{2x} \ dx[/tex]  

Evaluating the integral by using integration:

[tex]u=x\\\\dv=e^{9x} \ dx[/tex]

Let

[tex]u=x\\\\ dv=e^{9x} dx[/tex]

Then,

[tex]\to \frac{du}{dx}= 1 \ and\ v =\int e^{9X} \ dx \\\\\to du = 1 \ dx \\\\\to v = \frac{e^{9x}}{9}\\\\\text{integrate the above value}:\\\\\int\ u \ dv = uv - \int v du \\\\Now, \\\\\to \int x e^{9X} \ dx = x \frac{e^{9x}}{9} - \int \frac{e^{9x}}{9} dx[/tex]

                     [tex]= \frac{ x \ e^{9x}}{9} - \frac{e^{9x}}{9}\\\\= \frac{ \ e^{9x}}{9} (x-1)+C\\[/tex]

Which expression represents the perimeter, in centimeters, of the triangle

Answers

Answer:

8t + u - 7 or -7 + u + 8t ( to match the multiple choice answers)

Step-by-step explanation:

the perimeter is the distance around an object, therefore we need to add up all three sides of the triangle to get the perimeter

2t + 2 + 6t - 7 + u - 2 = perimeter

combine like terms to simplify

2t + 6t + u + 2 - 2 - 7
