One way is to just expand it by using binomial theorem
or to use pascal's triangle
ok so
to find the nth term of a binomial, (a-b). where the binomial is to the r power you do
n-1=k
rCk times

and rCk=

so
4th term
4-1=3
6 is exponent
6C3

=

=

=

the 4th term is
The first one because it’s (13(31)
Answer:

Step-by-step explanation:
The equation of a circle is
where
is the center of the circle and
is the radius of the circle.
Given that
and it passes
, their distance between each other must the radius of the circle, so we can use the distance formula to find the radius:

Therefore, if the length of the radius is
units, then
, making the final equation of the circle 
Answer:
g(0) > f(0)
Step-by-step explanation:
Evaluate the functions at the point of interest: x=0.
g(0) = 20·1.5^0 = 20·1 = 20
f(0) = -40 . . . . from the table
Since 20 > -40, we conclude ...
g(0) > f(0)
