Mathematics
1 answer:
Dimas [21]2 years ago
3 0

Answer:

2. The answer should be the last one.

3. The answer should be the first three.

Step-by-step explanation:

<u>Question 2</u>

KE = (1/2)mv²

2KE = mv²

v² = 2KE/m

v = ±√(2KE/m)

Therefore the answer should be the last one.

<u>Question 3</u>

b^(1/2) * b^(5/2)

Remember that the <u><em>product rule</em></u> states that b^x * b^y = b^(x+y)

So this means b^(1/2) * b^(5/2) = b^(1/2+5/2) = b^(6/2) = b^3

Also remember that the <u><em>power rule</em></u> states that √b = b^(1/2)

so this means b^(6/2) can also be written as (√b)^6

Therefore the answer should be the first three.

<em>If you want to double check all of your answers, just replace b with a number (for example, 2), and plug all of the choices into the calculator. Just </em><u><em>make sure</em></u><em> you are </em><u><em>very careful</em></u><em> when typing into the calculator.</em>

Here's the solution :

  • \dfrac{7}{ \sqrt{10 }  -  \sqrt{ 3} }

  • \dfrac{7}{ \sqrt{10} -  \sqrt{ 3}  }  \times  \dfrac{ \sqrt{10}  +  \sqrt{3} }{ \sqrt{10}  +  \sqrt{3} }

  • \dfrac{7( \sqrt{10}  +  \sqrt{3} )}{( \sqrt{ 10}) {}^{2} - (  \sqrt{ {3}})^{2}  }

  • \dfrac{7 (\sqrt{10}  +  \sqrt{3}) }{10 - 3}

  • \dfrac{7( \sqrt{10}  +  \sqrt{3} )}{7}

  • \sqrt{10} +  \sqrt{3}

In this question, we are asked to calculate the number of ways in which the letters of the word balloon can be arranged.

To do this, we take into consideration those letters that are repeated and the number of times repeated. The letters are l and o and are repeated two times each.

The number of ways = 7!/2!2! = 5040/4 = 1,260 ways
