Step-by-step explanation:


Hence lake will never be free of pesticide.
X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
r=8
Answer:
Either <em><u>10 times</u></em> or <u><em>598,000.</em></u>
Step-by-step explanation:
6 x 10 ^ 5 = 600,000
2 x 10 ^ 3 = 2,000
If we are figuring out the exact number, 600,000 - 2,000. If we are finding out how many powers larger, count.
600,000 - 2,000 = 598,000
600,000 is 10 times larger than 2,000.
