Answer:
The area is given by:
And replacing we got:
So then we can conclude that the area of the coin is 
mm^2
Step-by-step explanation:
For this case we know that we have a coin with a diamter of 
, and by definition the radius is given by:
The area is given by:
And replacing we got:
So then we can conclude that the area of the coin is mm^2
1) A graph is linear when the line on a graph is a straight line with no curves.
2) A proportional graph means that as x increases, y increases and when x decreases, y decreases and their ratio always stays the same.
3) (I don't know what type of equation you mean but this is my guess)
Division is the last step of an equation.
1. Is a right angle
2.is a obtuse.
Slope = (25 - 13)/(-7 + 4) = 12/-3 = -4
<span>passing through the points (-7, 25) and (-4, 13)
</span>y = mx+ b
13 = -4(-4) + b
b = 13 - 16
b = -3
equation
y = -4x - 3
hope it helps
