Answer:

The volume of water that can be hold by the pool is approximately 770 cubic feet.  

Step-by-step explanation:

To calculate it we have to use the volume formula for a cylinder. This is:

Volume=pi*r^{2}*h\\pi=3.14\\r=radius\\h=deep

Solving the equation with the given values:

Volume=3.14*7^{2} *5\\Volume=769.3 cubic feet \\Aprox.Volume= 770 cubic feet

The volume of water that can be hold by the pool is approximately 770 cubic feet.

select whether the equation has a solution or not, square root x-2- square root 2x= square root x+2 (a. roots b. no roots)
Agata [3.3K]

The equation is \sqrt{x-2 \\ \\ -\sqrt{2x} = \sqrt{x +2}


Solution

<u>Step 1:</u>

Take square on both sides, we get

3x - 2\sqrt{x-2}\sqrt2{x} -2 = x +2

<u>Step 2:</u>

Subtract 3x - 2 from both sides, we get

-2\sqrt{x-2} \sqrt{2x} = -2x + 4

<u>Step 3:</u>

Again, square on both sides in order to get rid of the square root from the above equation, we get

8x^{2}-16x = 4x^{2} -16x +16

Now we have to simplify it,

4x^{2} -16 = 0

<u>Step 4:</u>

Now we have to solve this quadratic equation, in order to get the solution.

We get x = 2 and x = -2, When we verifying solution in the original given equation, the solution does not satisfy the equation.

Reason: We get negative number in the square root.

Therefore, it has no Roots.


<em>Answer: b) No roots</em>

Permutation:
Kruka [31]

Formula for permutation is:

\boxed{ \tt^{n} C_{r} =  \frac{n!}{r!(n - r)!} }

<h3><u>Calculation</u>, </h3>

Plug in the values:

Required number of ways = ²C7

  • n = 7
  • r = 5

\sf \frac{7!}{5!(7 - 5)!}

\sf \frac{7 \times 6 \times  \cancel{5!}}{ \cancel{5! }\times 2!}

\sf \frac{7 \times 6 }{ 2!}

\sf \frac{42 }{ 2!}

\sf \frac{42 }{ 2}  = 21

<em>Thus, </em><em>The</em><em> </em><em>players</em><em> </em><em>can</em><em> </em><em>be</em><em> </em><em>selected</em><em> </em><em>in</em><em> </em><em>21</em><em> </em><em>different</em><em> </em><em>ways</em><em>!</em><em>!</em><em>~</em>
