Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the center at (-3, -5) and the radius r = 6. Substitute:
For this case we have the following polynomial:
To find the value of c that completes the square, we use the following equation:
Where,
- <em>b: coefficient of the variable of degree 1
</em>
Substituting values we have:
Answer:
the value of c that completes the square is:

Answer:
$7.198 * 10^6
Step-by-step explanation:
Given that :
Total Area of Alaska = 5.9 * 10^5 mi²
Cost of Alaska per square mile = $12.20
Total amount paid to purchase Alaska:
(Total area in square miles * Cost per square mile)
(5.9 × 10^5) * $12.20
(5.9*12.20) * 10^5
71.98 * 10^5 dollars
= $7.198 * 10^6
Hence, amount the United States paid Russia for the purchase of Alaska is approximately $7.198 * 10^6
