Hi!
The equation of a circle is (x – h)² + (y – k)² = r², with (h, k) being the center, r being the radius, and x + y being left as just x and y.
If the smallest circle has a radius of 3 units, then the next one is 7 units (4 units greater), and then the second largest 11 units, and then the largest 15. That means, for r in our equation, we're going to put in 15.
So we get:
(x – h)² + (y – k)² = 15², or
(x – h)² + (y – k)² = 225
The center of our circle is at (-4, 3). That means h = -4 and k = 3 in our equation. So let's substitute that in.
(x – (-4))² + (y – 3)² = 225
(x + 4)² + (y - 3)² = 225 is our final equation.
Hope this helped!
4, 3, 7 I hope this helped :)
The order from least to greatest is 4 7/ 8, 4 9/ 10 , 5
<h3>What are fractions?</h3>
Fractions are simply representatives of part of a whole.
The types of fraction are;
- Mixed fractions
- Simple fractions
- Improper fractions
- Proper fractions
From the information given, we have to arrange in order from least to greatest
5, 4 7/8, 4 9/10
Turn mixed fractions to improper fractions;
5, 39/ 8 , 49/ 10
From least to greatest is written thus;
39/ 8, 49/ 10 , 5
Thus, the order from least to greatest is 4 7/ 8, 4 9/ 10 , 5
