Given equation of a circle: x^2 – 4x + y^2 + 6y = 12 rewrite it in a standard form. Find its radius and coordinates of its cente
Yuki888 [10]

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

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
Kay [80]
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 = \frac{Distance}{Time}

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 = \frac{48}{3}

Simplify the fraction to get the speed.
\frac{48}{3} = 16.

Your final equation is:
Speed = 16.

Our final answer is 16 mph.

I hope this helps!
