Answer:
c. 38
Step-by-step explanation:
We are given the following coordinates:
(0,6), (π/2, 7); (π, 8); (3π/2, 7); and (2π, 6)
If we graph these points, we will observe that the function is a cosine function. Since the function does not pass through the origin. Instead, it has a y-intercept equal to 6. <span />

Answer:
<h2>The standard form: x² + (y + 1)² = 25</h2><h2>The general form: x² + y² + 2y - 24 = 0</h2>
Step-by-step explanation:
The equation of a circle:

(h, k) - center
r - radius
We have the center (0, -1) and the radius r = 5 <em>(look at the picture)</em>.
Substitute:

<em>use (a + b)² = a² + 2ab + b²</em>
<em>subtract 25 from both sides</em>
