Answer:
729
Step-by-step explanation:
x=
9^3=729
729×(9/9^6)
9/9=1
1^6=1
Therfore, 729×1=729
The upper one is correct. Because 0,75% = 0,0075 ( :10) and since the interest rate is positive it has to be 1 + ...
An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one
so
when n=1, an=40
so a1=40
it seems to increas by 7 each time
an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula
the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term
domain is natural numbers
the formula is
