Step-by-step explanation:
If the centre of a circle is (a, b) and radius r, then the equation of the circle is :
<em><u>First we will find the centre, (a , b): </u></em>
<em><u /></em>
<em><u /></em>
<em><u>Find radius:</u></em>
Diameter is the distance between (-1, 4) and (3, -2)
Therefore , 
<em><u>Equation of the circle is : </u></em>

So he needs to sell $2,000 in merchandise.
<h3>what is the total value of merchandise he needs to sell?</h3>
We can assume that we have a proportional relation:
y = k*x
Where y is the commission and x is what Norman sells, then:
$15 = k*$200
k = $200/$15 = 0.075
$37.50 = k*$500
k = $500/$37.50 = 0.075
Then the relation is:
y = 0.075*x
If he wants a commission of $150, then:
$150 = 0.075*x
$150/0.075 = x = $2,000
So he needs to sell $2,000 in merchandise.

Answer:
Step-by-step explanation:
- Well I hate to break the news but 243 is not a perfect square. I'll work you through it, 243 is not a perfect square because it is not an even number. an even number must end in (0,2,4,6,8)
- Step one. Find the square root. the square root of 243 is <em>15.588. </em>
- Step two Is it a perfect square. No 243 just cant be a perfect square.
- Hope this helped :)
