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]

Answer:

[tex]\displaystyle \int {xe^{9x}} \, dx = e^{9x} \bigg( \frac{x}{9} - \frac{1}{81} \bigg) + C[/tex]

Step 2: Integrate Pt. 1

Identify variables for integration by parts using LIPET.

Set u: [tex]\displaystyle u = x[/tex][u] Differentiate: [tex]\displaystyle du = dx[/tex]Set dv: [tex]\displaystyle dv = e^{9x} \ dx[/tex][dv] Integrate [Exponential Integration]: [tex]\displaystyle v = \frac{e^{9x}}{9}[/tex]

Step 3: Integrate Pt. 2

[Integral] Integration by parts: [tex]\displaystyle \int {xe^{9x}} \, dx = \frac{xe^{9x}}{9} - \int {\frac{e^{9x}}{9}} \, du[/tex][Integral] Rewrite [Integration Property - Multiplied Constant]: [tex]\displaystyle \int {xe^{9x}} \, dx = \frac{xe^{9x}}{9} - \frac{1}{9} \int {e^{9x}} \, du[/tex]

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

Answer:

f(1) = - 1

f(-1) = - 2

Step-by-step explanation:

f(1) will lie in the function f(x) = - 2x + 1

Therefore,

f(x) = - 2x + 1

Plug x = 1

f(1) = - 2*1 + 1 = - 2 + 1 = - 1

f(-1) will lie in the function f(x) = - x - 1

Therefore,

f(x) = - x - 1

Plug x = - 1

f(-1) = - 1 - 1 = - 2

Answer:

-1, 0, 1, 11, 3

Step-by-step explanation:

Function 1

f(x) = -2x + 1f(1) = -2(1) + 1 = -2 + 1 = -1

Function 2

f(x) = -x - 1f(-1) = -(-1) - 1 = 1 - 1 = 0

Function 3

f(x) = x + 3f(-2) = -2 + 3 = 1

Function 4

f(x) = 2x + 1f(5) = 2(5) + 1 = 11

Function 5

f(x) = 3f(6) = 3
