Add MN and NR together.
25 + 12 = 37. Make sure to add the word units on the end if it’s not multiple choice.

Y = 3 sin2x, y = 0, 0 ≤ x ≤ π; about the x−axis

Dominik [7]

I assume you're revolving the region with those bounds about the x-axis, and supposed to find the volume.

Via the disk method,

$\displaystyle\pi\int_0^\pi(3\sin2x)^2\,\mathrm dx=9\pi\int_0^\pi\sin^22x\,\mathrm dx$

Recall the half-angle identity for sine:

$\sin^2t=\dfrac{1-\cos2t}2$
$\implies\displaystyle\frac{9\pi}2\int_0^\pi(1-\cos4x)\,\mathrm dx$
$=\displaystyle\frac{9\pi}2\left(x-\frac14\sin4x\right)\bigg|_{x=0}^{x=\pi}$
$=\dfrac{9\pi^2}2$

Solve equation:<br> -3|d-5|=-6

gulaghasi [49]

Answer:

d = 7, 3

Step-by-step explanation:

First, you need to isolate the absolute value

-3|d - 5| = -6

divide both sides by -3:

|d - 5| = 2

break into 2 equations:

d - 5 = 2, d - 5 = -2

solve both equations and collect solutions:

d = 5 + 2, d = 5 - 2

d = 7, 3

How do I find the volume of this need help

Irina-Kira [14]

To find the volume, you need to multiply l x w x h

5 x 7 x 10

5 x 7 = 35

35 x 10 = 350

350 is the correct answer

Glad I could help, and good luck!
