Step-by-step explanation:
The domain of this relation (not a function) is x = -5. The relation is not defined for any other x value.
You would need to find the area of which the irrigation would cover:
Area of a circle=pi*r^2
=300^2*pi
=90000pi ft^2
Hope this helps
1,800square ft/$1,200
1.5 square ft for $1
Now to find the area of mr. halloran’s office
$18,000/12 months = $1,500 per month
$1,500•1.5 sqft = 2,250 square feet
So mr. Halloran’s office area is 2,250 square feet and he pays $1,500 per month
