40.51x+12.45y=666.64
irga5000 [103]

Answer:

The graph of the equation 40.51x+12.45y=666.64 is attached with the answer where the horizontal axis represents the X axis and the vertical axis represents Y axis.

To plot the graph physically just find two points lying on the line. Mark the points on the graph sheet and then join them. This will give you the line represented by the equation.

To find points on the line assume the value of any one variable, substitute it in the equation, then solve the equation to find the value of other variable. For example : assume y = 1; substitute the value of y in the equation;

⇒ 40.51x + 12.45×1 = 666.64

⇒ 40.51x = 666.64 - 12.45

⇒ 40.51x = 654.19

⇒ x = \frac{654.19}{40.51}

⇒ x ≈ 16.149

Therefore point ( 16.149 , 1 ) lie on the graph of the equation.

***Only two points are required to plot this graph just because it represents a straight line, that we can conclude just by observing the equation. If in an equation the power of x is 1 or 0 and power of y is 1 or 0 then only it will represent a straight line in 2-D plane.***

Expand and reduce (2+√3)^2
nasty-shy [4]

Answer:

7 + 4\sqrt{3}

Step-by-step explanation:

note that \sqrt{a} × \sqrt{a} = a

Given

(2 + \sqrt{3} )² = (2 + \sqrt{3} )(2 + \sqrt{3} )

Each term in the second factor is multiplied by each term in the first factor, that is

2(2 + \sqrt{3} ) + \sqrt{3}(2 + \sqrt{3} ) ← distribute both parenthesis

= 4 + 2\sqrt{3} + 2\sqrt{3} + 3 ← collect like terms

= 7 + 4\sqrt{3}

Bond [772]
Distributions from owners are earnings that an owner withdraws from a business based on the profit that the company has made. It is payed in the form of a dividend. ADR stands for American Depositary receipt. ADR <span>is a stock that trades in the United States and represents a specified number of shares in a foreign corporation. So, the payment that the owner will get will not be from the ADR stock.</span><span>
