Answer:

use (pi*r^2)/2 to find the area of one semi circle, then multiply it by 2 to find the total of both semi circles

the diameter is 3, so the radius is 1.5

approx 7.06858347058

=approx 14.1371669412

+6 (the rest of the blocks)

=20.1371669412

approx = 20.14 =20

Find the measure of x

Dahasolnce [82]

Answer:

Step-by-step explanation:

The angle adjacent to the 106 degree angle is 180 degrees - 106 degrees, or 74 degrees. Next, the adjacent angle to the 145 degree angle is 35 degrees; in other words, the two bottom angles of this triangle are 35 degrees and 35 degrees. That means that a 35 degree angle is vertical angle to x, and so x is also 35 degrees.

The sum of the three interior angles is 35 degrees + 74 degrees and

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

Lemur [1.5K]

Answer:

The answer is " $\bold{ \frac{ x \ e^{2x}}{2} - \frac{e^{2x}}{4}+C}$ "

Step-by-step explanation:

Taking the integral $\int x^{2x} \ dx$

Evaluating the integral by using integration:

$u=x\\\\dv=e^{2x} \ dx$

Let

$u=x\\\\ dv=e^{2x} dx$

Then,

$\to \frac{du}{dx}= 1 and v =\int e^{2X} \ dx \\\\\to du = 1 dx \\\\\to v = \frac{e^{2x}}{2}\\\\\text{integrate the above value}:\\\\\int u dv = uv - \int v du \\\\Now, \\\\\to \int x e^{2X} \ dx = x \frac{e^{2x}}{2} - \int \frac{e^{2x}}{2} dx$

$= \frac{ x \ e^{2x}}{2} - \frac{e^{2x}}{4}+C$
