Answer:
5
Step-by-step explanation:
We desire to evaluate the fraction: when k=3.
This is a simple substitution, so what is required is
- Replace k with the given number
- Simplify the resulting expression
Therefore, when k=3
You can try the same for any value of k.
Answer:
Center: (3, -2)
Radius: 4.
Step-by-step explanation:
The equation of a circle is (x - h)^2 + (y - k)^2 = r^2.
In this case, the equation given is (x - 3)^2 + (y + 2)^2 = 16.
That means that h = 3, and k = -2. In other words, the center of the circle is (3, -2).
The radius will be
= 4
Hope this helps!
