Answer:
centre = (13,0)
radius = 8
Step-by-step explanation:
The standard equation of the circle is
(x-x0)^2 + (y-y0)^2 = r^2 ...............(1)
where
(x0,y0) is the centre,
r is the radius.
For
(x-13)^2 + y^2 = 64 ..............(2)
we rewrite (2)
(x-13)^2 + (y-0)^2 = 8^2 ...............(3)
and compare (3) with (1)
to identify
x0 = 13, y0 = 0, and r = 8
Therefore
centre = (13,0)
radius = 8

Step-by-step explanation:
The median is the number in the middle when all of the numbers are placed in order (from lowest to highest).
15; 17; 19; 42; 78; 85; 93
The answer in this case would be 42.

P = the principal
t = 25 years the time in years
r = 0.0525 or 5.25% annual rate
m = 1 compounding periods per year
i = 0.0525 or 5.25% interest rate per period
n = t*m = 25 total number of compounding periods
A = $75,000 future value
A = P(1 + i)^n
P(1 + i)^n = A
P(1 + 0.0525)^25 = 75000
by solving we find:
P = $20,869.34
