Relations are subsets of products <span><span>A×B</span><span>A×B</span></span> where <span>AA</span> is the domain and <span>BB</span> the codomain of the relation.

A function <span>ff</span> is a relation with a special property: for each <span><span>a∈A</span><span>a∈A</span></span> there is a unique <span><span>b∈B</span><span>b∈B</span></span> s.t. <span><span>⟨a,b⟩∈f</span><span>⟨a,b⟩∈f</span></span>.

This unique <span>bb</span> is denoted as <span><span>f(a)</span><span>f(a)</span></span> and the 'range' of function <span>ff</span> is the set <span><span>{f(a)∣a∈A}⊆B</span><span>{f(a)∣a∈A}⊆B</span></span>.

You could also use the notation <span><span>{b∈B∣∃a∈A<span>[<span>⟨a,b⟩∈f</span>]</span>}</span><span>{b∈B∣∃a∈A<span>[<span>⟨a,b⟩∈f</span>]</span>}</span></span>

Applying that on a relation <span>RR</span> it becomes <span><span>{b∈B∣∃a∈A<span>[<span>⟨a,b⟩∈R</span>]</span>}</span><span>{b∈B∣∃a∈A<span>[<span>⟨a,b⟩∈R</span>]</span>}</span></span>

That set can be labeled as the range of relation <span>RR</span>.

George had $6,000 in a savings account earning simple interest at a rate of 5% per year. At the end of the year, George paid 25%
Readme [11.4K]

Answer:

<em>$225</em>

<em></em>

Step-by-step explanation:

Given that:

Principal = $6,000

Interest rate = 5%

Time = 1 year

Taxes paid = 25% on the interest earned

To find:

Money earned after paying taxes ?

Solution:

First of all, let us calculate the total interest earned:

Formula for Simple Interest is given as:

SI =\dfrac{PRT}{100}

Where P is the principal

R is the rate of interest

T is the time taken

Putting the given values:

SI =\dfrac{6000 \times 5\times 1}{100} =\$300

Now, it is given that 25% of the interest earned is given as taxes.

Taxes paid = 25% of $300

\Rightarrow \dfrac{25}{100} \times 300 =\$75

Therefore, the money earned = Interest earned - Taxes paid

The money earned = $300 - $75 = <em>$225</em>

Find the volume of the sphere
son4ous [18]

Given:

The radius of the given sphere = 1 unit

To find the volume of the sphere.

Formula:

The volume of the sphere of radius r is

V = \frac{4}{3} \pi r^{3}

Now,

Substituting r=1 and π=3.14 (as given), we get

V = \frac{4}{3} (3.14)(1^{3}) cube unit

or, V = 4.187 cube unit

Hence,

the volume of the cube is 4.187 cube unit.

Khan question, please help
barxatty [35]

Answer:

A

Step-by-step explanation:

Khan gives you right answer and tells you what's wrong, but this site is for help so, all you need to do is use the destructive property.

12 x 2= 24 12 x 3 = 36 12 x -1 = -12

now you have the original expression, 24 + 36 - 12 (without the letters.)
