The area of a square is 160x^5y^2. What is the length of one side?

Aleksandr [31]

------------------------------------------------------------------
Formula of area of square
------------------------------------------------------------------
Area of square = Length x Length
Area of square = Length2

------------------------------------------------------------------
Given information
------------------------------------------------------------------
Area of square = $160x^5y^2$

------------------------------------------------------------------
Find length
------------------------------------------------------------------
$length^2 = 160x^5y^2$
$length = \sqrt{160x^5y^2}$
$length = 4y\sqrt{10x^5}$

-----------------------------------------------------------------
$\Longrightarrow \ Answer: \boxed {\boxed{ 4y\sqrt{10x^5} }}
$

Describe how the graph of y= x2 can be transformed to the graph of the given equation.

Stels [109]

Assume you mean the transformation from x^2 to (x-10)^2 + 8

Then, you first shift x^2 10 units right, you will get (x-10)^2

And, shift (x-10)^2 8 units upward, you will get (x-10)^2 + 8

To raise money for the

masha68 [24]

Answer:

x = 60

y = 200

Step-by-step explanations:

Selling price:

Price of program = $0.5

Price of music = $5

Cost of production :

Program = $0.15 per program

CD = $1.75 per CD

Total Revenue = $400

Total Profit = $265

Let

Number of CD's = x

Number of program's = y

(0.5y + 5x) = 400

0.5y = 400 - 5x

y = (400 - 5x) / 0.5

y = 800 - 10x (1(

Cost of production:

1.75x + 0.15y

Profit = Total Revenue - Total cost of production

5x + 0.5y - 1.75x + 0.15y = 265

3.25x + 0.35y = 265 (2)

Put y = 800 - 10x in (2)

3.25x + 0.35y = 265

3.25x + 0.35(800 - 10x) = 265

3.25x + 280 - 3.5x = 265

-0.25x = - 15

Divide both sides by -0.25

x = -15/ -0.25

x = 60

y = 800 - 10x

= 800 - 10(60)

= 800 - 600

= 200

y = 200
