Answer:
AB = 4
Step-by-step explanation:
Calculate AB using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(6, 2) and (x₂, y₂ ) = B(0, 10)
AB = 
= 
= 
= 
= 4 ← exact length
There is a formula for that;
Total time = (Worker 1 * Worker 2) / (Worker 1 + Worker 2)
Total time = (80 * 120) / (80 + 120)
Total time = 9,600 / 200
Total time = 48 minutes
Answer:
a.
Step-by-step explanation:
D1 = 60 for a price of $80. Charging $80 will ensure supply exceeds demand.
