Pyramid A is a square pyramid with a base side length of 14 inches and a height of 6 inches. Pyramid B has a volume of 3,136 cub

leonid [27]

The Volume of PYRAMID A is 8 times greater than the Volume of PYRAMID B as obtained by taking the ratio of the volume of both pyramids.

Volume of a square based pyramid is given as :

$V = a^2h/3$

Where; h = height ; a = base edge

Hence, Volume of PYRAMID A :

$V = 14^2 * (6/3)\\\\V = 392 in^3$

Volume of PYRAMID B = 3,136 in³

Divide Volume of pyramid B by pyramid A :

$3136 in^3 / 392 in^3$

= 8 times

Expressing as a percentage, multiply by 100% ;

8 * 100% = 800%

Therefore, The volume of PYRAMID B is 800% times GREATER THAN that of PYRAMID A.

Which one of the following graphs is the graph of:3if -2 < x < 01if x = 0if 0 < x≤ 2f(x) =A.44B.4-²-(x + 1)?

In-s [12.5K]

Given the piecewise function:

$f(x)=\begin{cases}{3\text{ if -2}\leq x$

Let's select the graph which represents the function.

We have the graph below:

For f(x) = 3, the graph will be a horizontal line on y = 3 which has an open dot on x = 0 and a closed dot on x = -2

For f(x) = 1 if x = 0, the graph will have a closed dot located on the point (0, 1)

For f(x) = -(x + 1) if 0 < x ≤2, the graph will have a negative slope with an open dot on (0, -1) and closed dot on (2, -3)

Solve the differential equation dy dx + 12x2y = 36x2. SOLUTION The given equation is linear since it has the form of this equati

Georgia [21]

Answer:

Therefore the solution of the differential equation is

$ye^{4x^3} = 3e^{4x^3}+c$ [ where c is arbitrary constant]

Step-by-step explanation:

Given differential equation is

$\frac{dy}{dx} +12x^2y= 36x^2$

Here $P(x)= 12x^2$ and $Q(x) = 36 x^2$

The integrating factor of the differential equation is

$= e^{\int P(x) dx$

$=e^{\int 12x^2dx$

$=e^{ \frac{12x^3}{3}}$

$=e^{4x^3}$

Multiplying the integrating factor both sides of the differential equation

$e^{4x^3}\frac{dy}{dx} +12x^2ye^{4x^3}= 36x^2e^{4x^3}$

$\Rightarrow e^{4x^3} dy+12x^2ye^{4x^3}dx= 36x^2e^{4x^3}dx$

Integrating both sides,

$\int e^{4x^3} dy+\int12x^2ye^{4x^3}dx= \int36x^2e^{4x^3}dx$ ......(1)

Let

$I= \int36x^2e^{4x^3}dx$

$= \int3. 12 x^2e^{4x^3}dx$

putting ${4x^3}=z$ , $12x^2 dx=dz$

$=\int 3. e^zdz$

$=3e^z+c$ [ where c is arbitrary constant]

Putting the value of z

$=3e^{4x^3}+c$

From (1) we get

$\int e^{4x^3} dy+\int12x^2ye^{4x^3}dx= \int36x^2e^{4x^3}dx$

$\Rightarrow ye^{4x^3} = 3e^{4x^3}+c$

Therefore the solution of the differential equation is

$ye^{4x^3} = 3e^{4x^3}+c$ [ where c is arbitrary constant]
