Answer:
≈ 7.07
Step-by-step explanation:
Calculate the length using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (- 7, - 2)
d =

Answer:
(A) $500,000
Step-by-step explanation:
Given formula for finding the cost ( in dollars ) to remove p percent of a certain pollutant,
If P = 90,
If P = 80,
∵ 900000 - 400000 = 500000,
Hence, it will cost $500,000 more to remove 90% of the pollutant from the pond than it would cost to remove 80% of the pollutant,
Option '(A)' is correct.
