Delivery Charges. A furniture store offers free setup and delivery services to all points within a 24-mi radius of its warehouse distribution center. If you live 20 mi east and 12 mi south of the warehouse, will you incur a delivery charge? 
A) no
B) yes

Quizplus · Accepted Answer

The distance from the warehouse to the customer's location is calculated using the Pythagorean Theorem:

distance^2 = (20^2) + (12^2)
distance = sqrt(400+144) = sqrt(544) ≈ 23.3 mi

Since the customer is within a 24-mi radius, they will not incur a delivery charge.
