Answer:

Option B

Step-by-step explanation:

Given is a term under square root sign.

Inside square root is given a rational function in n as

\frac{60n^{11} }{256n^{4} }

Simplify constant terms and n terms separately to get

=\frac{15n^7}{64} \\=\frac{n^3}{8} \sqrt{15n}

Out of the four options option 2 matches with this.

Hence correct answer is option B.

We have been given an expression \sqrt{\frac{60n^{11}}{256n^4}}. We are asked to simplify our given expression.  

First of all, we will simplify the expression inside radical as:

\sqrt{\frac{15n^{11}}{64n^4}}

Using exponent property \frac{a^b}{a^c}=a^{b-c}, we will get:  

\sqrt{\frac{15n^{(11-4)}}{64}          

\sqrt{\frac{15n^{7}}{64}

Now we will use exponent property \sqrt{\frac{a^b}{a^c}}=\frac{\sqrt{a^b}}{\sqrt{a^c}}.

\frac{\sqrt{15n^7}}{\sqrt{64}}

\frac{\sqrt{15n\cdot n^6}}{\sqrt{8^2}}

\frac{\sqrt{15n\cdot (n^3)^2}}{\sqrt{8^2}}

Now we will bring out perfect squares from radical as:

\frac{n^3\sqrt{15n}}{8}

Therefore, simplified form of our given expression would be \frac{n^3\sqrt{15n}}{8} and option B is the correct choice.

A piece of toast came out of the toaster very overcooked.
Nikitich [7]

Answer:

It is a chemical change ⇒ 1st answer

Step-by-step explanation:

* Lets explain the statements to solve the problem

- <u><em>A chemical change</em></u> occurs when a new substance is formed through

 a chemical reaction

- Ex: cooking an egg

- <u><em>Change of reaction</em></u> is the rate of reaction it can be decreases or

  increasing

- <u><em>A phase change</em></u> is a change from one state to another without a

 change in chemical composition

- Ex: Condensation: the substance changes from a gas to a liquid

- <u><em>A physical change</em></u>, such as a state change or dissolving, but does

 not create a new substance

- Ex: Breaking a glass

* Lets solve the problem

- A piece of toast came out of the toaster very overcooked.

∵ It is like the cooking an egg

∴ It is a chemical change

I need help finding y
denpristay [2]

Answer:

y = 9.8995

Step-by-step explanation:

This question requires the use of basic trigonometry.

In this problem, we know one of the sides and two of the angles.

Since one of the angles is 45 degrees and the sum of all internal angles of a triangle is 180 degrees, the other angle can only be 45 degrees, making this an isosceles triangle - that is, the length of the other leg, x, is also 7.

You could use the soh cah toa mnemonic to figure it out, but here just using the a^2 + b^2 = c^2 should be sufficient since we know both legs of the triangle.

7^2 + 7^2 = 98, and the square root of 98 gives you about 9.8995, which sounds about right for this situation.

Hope this helped!
