sorry if its the wrong equation, the questions sometimes glitch but if it is maybe this will kind of be an example of how to do it

Answer:

324 cubes.

Step-by-step explanation:

#### be the number of cubes with edge length 1/12 meter.

We have been given the lengths of edges of a right rectangular prism as  meter,  meter and  meter.

, where,

L = Length of prism,

B = Breadth of prism,  

H = Height of prism.

, where a= length of each edge of the cube.

The volume of n cubes with each edge 1/12 will be equal to the volume of rectangular prism.  

Upon substituting our given values we will get,

Let us multiply both sides of our equation by 1728.

Therefore, 324 unit cubes can fit inside the given right rectangular prism.

sorry if its the wrong equation, the questions sometimes glitch but if it is maybe this will kind of be an example of how to do it

satela [25.4K]

Answer:

  • B. $45341.60

Step-by-step explanation:

<u>Given:</u>

  • Initial profit = $37800
  • Rate of appreciation = 2.3% per year

<u>The equation for this:</u>

  • P(t) = 37800*(1 + 0.023)^t = 37800*1.023^t

<u>Find the value of P(8):</u>

  • P(8) = 37800*1.023^8 = 45341.60

Correct choice is B

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
