Answer:
4.583
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center of the circle and r is the radius.
x² + (y − 3)² = 21
The center of the circle is (0, 3), and the radius is √21, or approximately 4.583.
x² + (y - 3)² = 21
We know the formula is (x - xo)² + (y - yo)² = r²
So, 21 is the radius²
21 = r²
r = √21
r = 4,58257
Rounding
r = 4,583

D(600)=5
since the x axis represents the distance that corresponds to the time on y axis
600 meters correspond to 5 minutes
