2L + 2B =32m
L × B= 63m^2
Find 2 factors of 63 that add up to 32
2(9) + 2(7) = 32
The ans is 9m and 7m

blondinia [14]

Answer:

(-6, 8)

Step-by-step explanation:

2x + 3(8)= 12

2x + 24 = 12

-24 -24 (subtract 24 from both sides)

2x = -12

x= -6

Write the inverse of h(x) = e 2x <br>h -1(x) = <br><br>log e2 x <br>2log ex <br>½log ex

svp [43]

Answer:

C

Step-by-step explanation:

So we have the function:

$h(x)=e^{2x}$

To find the inverse, switch h(x) and x, change h(x) to h⁻¹(x), and solve for it. Thus: "

$x=e^{2h^{-1}(x)}$

So, take the natural log (log to base e) of both sides:

$\ln(x)=\ln(e^{2h^{-1}(x)})$

The right side will cancel:

$\ln(x)=2h^{-1}(x)$

Divide both sides by 2:

$h^{-1}(x)=\frac{1}{2}\ln(x)$

And we're done!

Our answer is C

Note:

$\ln(x)=\log_ex$

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. y = 8 sin(x

V125BC [204]

Answer with explanation:

The equation of two curves are

y=8 sin x

y=8 cos x

The point of intersection of two curves are

→8 sin x=8 cos x

sinx = cos x

$x=\frac{\pi}{4}\\\\y=8\sin\frac{\pi}{4}\\\\y=4\sqrt{2}$

When you will look between points , 0 and $x=\frac{\pi}{4}\\\\y=8\sin\frac{\pi}{4}\\\\y=4\sqrt{2}$ ,the curve obtained is right angled triangle.

Now, rotate the curve that is right angled triangle along the line , y= -1, to obtain a shape similar or resembling with Right triangular prism.

Draw a circular disc in the right triangular prism , having radius =x,and small part on the triangle having length dx.dx varies from 0 to $\frac{\pi}{4}$ .

Required volume of solid obtained

$=\int\limits^{\frac{\pi}{4}}_0 {8 \sin x} \, dx \\\\=|-8\cos x|\left \{ {{x=\frac{\pi}{4}}} \atop {x=0}} \right.\\\\=8-4\sqrt{2}$

=8-4√2 cubic units
