Using the distance formula, the distance between (-3, 4) and (2, -3) is: 8.6 units.
<h3>What is the distance formula?</h3>Distance formula for calculating the distance between two points on a coordinate plane is given as: .
Let,
(-3, 4) = (x1, y1)
(2, -3) = (x2, y2)
Plug in the values
c = 8.6 units.
Therefore, using the distance formula, the distance between (-3, 4) and (2, -3) is: 8.6 units.

Answer:
Radius of the convergence is R =
and,
The Interval of convergence is
Step-by-step explanation:
Given function : Σ(21x)^k
Now,
Using the ratio test, we have
R =
or
R =
or
R =
now,
for convergence R|x| < 1
Therefore,
< 1
or
and,
Radius of the convergence is R =
