Answer:
Step-by-step explanation:
1) point slope form is:
y-y1=m(x-x1)
y1=8
x1=4
m=(slope)
to find m: y2-y1/x2-x1
hence
-2-8/2-4=-10/-2=5
m=5:
y-8=5(x+4)
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
This is a simple differentiation problem. Let's start by taking the derivative of both sides (with respect to x):

Simplify:

Solve for dy/dx:

Now, plug in the given points:

Further simplification gives:

So,
your answer is 11/23 or
B.
