Answer:
<u>The standard form is:</u>
- (x - h)² + (y - k)² = r², where (h, k) is the center, r is the radius
<u>Convert the given into standard form by completing square:</u>
- x² - 4x + y² + 6y = 12
- x² - 4x + 4 + y² + 6y + 9 = 12 + 4 + 9
- (x - 2)² + (y + 3)² = 25
- (x - 2)² + (y + 3)² = 5²
- The standard form is above.
- The center is (h, k) = (2, -3)
- The radius is r = 5
Hello there! Thank you for asking your question here at Brainly! I will be assisting you today with answering this problem, and will teach you how to handle it on your own in the future.
First, let's take a look at our problem.
"The speed of a ship is given by D3, where D is the distance the ship travels in 3 hours. If the ship travels 48 miles in 3 hours, what is the speed of the ship?"
To solve for this, we need to understand the formula for speed.
The formula for speed is:
Speed = 
Now that we have our formula, let's
define our variables.
So, we have our distance, 48 miles, and our time, 3 hours.
Let's
plug in these numbers to the formula.
Speed =
Simplify the fraction to get the speed.

= 16.
Your final equation is:
Speed = 16.
Our final answer is
16 mph.I hope this helps!
Answer:
507 miles
Step-by-step explanation:
If each gallon can go 39 miles and the max number of gas it can hold is 13 gallons, then all you have to do is multiply 13 x 39, which equals 507
Answer:
8 cows survived
Step-by-step explanation:
