Volume = 1/3 * area of base * height

=1/3 * 11^2 * 15

= 605 cm^3 Answer

So to find the volume of a square pyramid, the formula is 1/3B2h or Base squared times height divided by 3 because of the triangular pyramid. So the base is 11, the height is 15 so 11 squared is 121 and the height is 15, so 121 times 15.

121 x 15= 1,815.

Now we divide by 3 because of the formula, so 1,815 divided by 3 is...

1,815 / 3= 605 cm squared!

Find a linear second-order differential equation f(x, y, y', y'') = 0 for which y = c1x + c2x3 is a two-parameter family of solu

Alisiya [41]

Let $y=C_1x+C_2x^3=C_1y_1+C_2y_2$ . Then $y_1$ and $y_2$ are two fundamental, linearly independent solution that satisfy

$f(x,y_1,{y_1}',{y_1}'')=0$
$f(x,y_2,{y_2}',{y_2}'')=0$

Note that ${y_1}'=1$ , so that $x{y_1}'-y_1=0$ . Adding $y''$ doesn't change this, since ${y_1}''=0$ .

So if we suppose

$f(x,y,y',y'')=y''+xy'-y=0$

then substituting $y=y_2$ would give

$6x+x(3x^2)-x^3=6x+2x^3\neq0$

To make sure everything cancels out, multiply the second degree term by $-\dfrac{x^2}3$ , so that

$f(x,y,y',y'')=-\dfrac{x^2}3y''+xy'-y$

Then if $y=y_1+y_2$ , we get

$-\dfrac{x^2}3(0+6x)+x(1+3x^2)-(x+x^3)=-2x^3+x+3x^3-x-x^3=0$

as desired. So one possible ODE would be

$-\dfrac{x^2}3y''+xy'-y=0\iff x^2y''-3xy'+3y=0$

160,000,000 in scientific notation and 58,413,000,000 please help me guys!!!

elixir [45]

160000000 =

move the decimal so only one number is to the left

we need to move it 8 times

1.60000000 *10^8

1.6*10^8

58413000000

move the decimal so only one number is to the left

5.8413000000 * 10^10

5.8413*10^10
