Answer:
Step-by-step explanation:
To write an equation for a circle, we need to find the center and the radius. We need to find the distance between the two endpoints to find the radius. To do that, use the distance formula:
d = √(2 - 5)² + (1 + 3)²
√(-3)² + (4)²
√9 + 16 = √25 = 5
If the diameter is 5, the radius is 2.5
Now we need to find the center/midpoint. Use the midpoint formula:
(5 + 2)/2, (-3 + 1)/2
7/2, -2/2
(3.5, -1)
Now that we have the center and the radius, we can make our equation. Remember that the equation of a circle is: (x - x of center)² + (y - y of center) = radius²
(x - 3.5)² + (y + 1)² = 6.25
Hope this helps

Answer:
15/17
Step-by-step explanation:
Remember SOH- CAH - TOA
The first number is between 200 and 225.
The second number is between 0 and 9.
Let's use the isolation process by taking away the numbers we know don't work.
Since the highest number is 9, any number that needs you to add more than 9 to get 217, is wrong.
we have limited it to 206-225.
But, you can't have the number be greater than 217 so we can limit the range again.
Now the numbers are between 206-217.
Now what we have to do is take the 1st number, and multiply it by the 2nd number to get 642. Whichever combo makes 642 is the answer.
Answer:
The first number is 214. The second number is 3.
