(2a^x +1/2 b^x)^2 thank you!!!!!!!!!!!!!!!!!!!1

kogti [31]

Note that (a+b)^2 = a^2 + 2ab + b^2.

Therefore,
b^x (b^x )^2
<span>(2a^x +1/2 b^x)^2 becomes (2a^x)^2 + 2(2a^x)(-------- ) + ------------
2 4

LCD is 4. Thus, we have

4 [ (2a^(2x) ] + 8</span>a^x*b^x + b^(2x)
<span> </span>

Evaluating integral by net area

N76 [4]

The graph of $f(x)=2$ is a horizontal line. So the area under $f(x)$ on [0, 8] is equal to the area of a rectangle with length 8 and height 2, or 16.

The graph of $g(x)=\sqrt{64-x^2}$ is the upper half of a circle with radius $\sqrt{64}=8$ . It's symmetric about $x=0$ , so on the interval [0, 8], we're considering a quarter of the circle. The area of such a sector is $\frac{\pi 8^2}4=16\pi$ .
