I need to simplify √(5+2√2) and √(6+2√5)
SIZIF [17.4K]
This expression is easier than it looks like. I thought that to solve it you have for example to express the 2 via 10 * 5^-1 and stuff like that - but you can multiply and divide this expression by some factor. In our case first we multiply by conjunctive expression root(5-2root2) and the second by root(6+2root5). In first we get root16 and the second calculate.

Please help!!!!!!!!!!!!
podryga [215]

Given : Fix amount charges = $200.

Each month additional charge = $50.

Let us assume number of months are taken by x.

So, we can setup a function as

Total charge  = Fix charge + each month charge * number of months.

f(x)  = 200 + 50*x

Or f(x) = 200 +5x.

Where function f is the total charge of x number of months.

The values of x's represents domain and function value represents range.

According to problem, it is said " first three months".

So, we need to take number of months as x=0,1,2,3.

And we need to find values of function for those x values.

On plugging x=0,1,2 and 3 we would get

f(0) = 200 +5(0) = 200 +0 = 200.

f(1) = 200 +5(1) = 200 +50 = 250.

f(2) = 200 +5(2) = 200 +100 = 300.

f(3) = 200 +5(3) = 200 +150 = 350.

We got function values 200,250,300 and 350.

Therefore, with respect to the given situation, the domain of the funtion is

{0,1,2,3} and Range { 200,250,300, 350}.

There are 6 squares and 15 triangles. What is the simplest ratio of squares to triangles?
Paladinen [302]

Answer:

2:5

Step-by-step explanation:

Hello!

A ratio is written as a:b.

Since we are writing it as a ratio of squares to triangles, "a" would be squares, and "b" would be triangles.

  • a:b
  • \text{squares  :  triangles}
  • 6:15
  • 3(2):3(5)    \hookrightarrow Remove common factors
  • 2:5

The simplest form of the ratio is 2:5.
