Answer:

Option D is correct.

Volume=\frac{8}{27}\ cubic\ yard

Step-by-step explanation:

Let V be the volume of hay in each stack

Given:

Length of the each stack is \frac{2}{3}\ yard

And Jay stores hay in cubic stacks on his farm.

The volume of the cone is.

Volume\ of\ cone = (side)^{3}

Now, we substitute value of length of stack in above equation.

V=(\frac{2}{3})^{3}

V=\frac{2^{3}}{3^{3}}

V=\frac{8}{27}\ cubic\ yard

Therefore, the volume of hay in each stack is V=\frac{8}{27}\ cubic\ yard

Amiraneli [1.4K]

4^x-2\cdot5^{2x}-10^x>0

$\implies 2^{2x}-2\cdot5^{2x}-(2^x)(5^x)>0$

let $2^x=a$ and $5^x=b$

So, $a^2-2b^2-ab>0$

divide by $b^2$, ($b^2>0$)

$\implies \left(\frac ab\right)^2-\left(\frac ab\right) -2>0$

this is a quadratic, in $\left(\frac ab\right)$, let it be $x$

So, $x^2-x-2>0$

Can you simplify it now?
