Answer:
Step-by-step explanation:
you multiply 2.56 by 3 and add 3.95 an equation would look like y=(3×2.56)+3.95
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
Answer:
B
Step-by-step explanation:
Using the identities
sec x =
, csc x =
, cot x =
, then
sec²x cot²x
=
×
( cancel out cos²x )
= 
= csc²x → B
