Y directly proportional to WX and inversely to Z.
Y=k(WX)/Z
Where k is the constant of proportionality.
So, the first thing is to find the value of this constant.
k = YZ/WX
= (32×3)/(6×20)
= 96/120
= 0.8
The <span>equation that models the relationship will be;
Y = 0.8(WX/Z)</span>
If you're talking about #3, then the equation would be 10+12.50h=5+15h.
h will equal 2, and the cost for that number of hours would then be $35.
Answer:
128 feet
Step-by-step explanation:

So now we will substitute the values of T and π into the equation.


Divide both sides by 6.28

Square both sides.

Multiply both sides by 32

<span> the equation of this circle is (x - 3)² + (y + 1)² = 4²</span>
