Answer:

(x + 2.3)^{2} + y^{2} = \frac{36}{49}

Step-by-step explanation:

To get the equation of a circle, plug your information into this equation:

(x - h)^2 + (y - k)^2 = r^2

Therefore, the equation of this circle is:

(x + 2.3)^{2} + y^{2} = \frac{36}{49}

Answer:

x is less than or equal to 3

Step-by-step explanation:

The dot is a closed dot, which means that it is something or equal to, and the arrow is pointing down, which means less than. So the sign would be less than or equal to (sorry I don't have that sign on my computer). The dot is on three, so the inequality is x is less than or equal to 3.

djyliett [7]
The next number is 38. The pattern is 7, 16, 8, 27, 9; if you look at the first 4 numbers, you notice that it counts to 7, 8, 9. Then you have 16 and 27, if the pattern continues; the next number is 38.
