Question:
The complete question as found on brainly (question-10746111):
Write down the nth term of each of the following G.Ps whose first two terms are given as follows. Also find the term stated besides each G.P.
i) 12,-3b,......sixth term
ii) 3,-1/3,..........;8th term?
Step-by-step explanation:
1) To solve terms involving Geometric progressions (GPs), we would first state the variables that are to be incorporated in the formula.
i) 12,-3b,......;sixth term
1st term = a= 12
r = common ratio = 2nd term /1st term
r = -3b/12 = -b/4
Then we would find the nth term
See attachment for details
ii) 3,-1/3,..........;8th term
1st term = a= 3
r = common ratio = 2nd term /1st term
r = (-⅓)/3 = (-⅓)(⅓) = -1/9
Then we would find the nth term
See attachment for details
2) we are to determine the sixth term in (i) and eight term in (ii)
See attachment for details
Sixth term= (-3b^5)/256
Eight term = -1/1594323
Answer:
1577.8 US dollars are received for 1127 UK pounds.
5669.5 UK pounds are received for US$7937.3.
Step-by-step explanation:
The questions are solved by proportions, using a rule of three.
How many US dollars are received for 1127 UK pounds?
1 UK pound = 1.4 US dollars
1127 UK pounds - x US dollars
Applying cross multiplication:
1577.8 US dollars are received for 1127 UK pounds.
How many UK pounds are received for US$7937.3?
1 UK pound = 1.4 US dollars
x UK pounds - 7937.3 US dollars
5669.5 UK pounds are received for US$7937.3.
