For this, I got the equation (X+3)^2-2 or X^2+6X+7. I used this method:
First I set up an equation (X+H)^2-K, where (K, H) is the vertex. All we have to do is find where the graph reaches its minimum value (because it opens upwards), then find the x-coordinate that lies there, which is (-2,3). Substituting these value in for H and K, we get the equation <span>(X+3)^2-2 or simplified X^2+6X+7.

Answer:
The circumference is 62.8 cm.
Step-by-step explanation:
To find the circumference, use 3.14 * 20 = 62.8
Answer:
The answer is A. k = 4.25.
Step-by-step explanation:
To find proportionality, solve for 8.5 divided by 2 and 17 divided by 4.
Both of those answers are 4.25, so that would be the final answer.
