Answer:
yes, the given relation is a function.
Step-by-step explanation:
The given relation is
{(–3, –2), (–1, 0), (1, 0), (5, –2)}
A relation is called function if each element of the domain is paired with exactly one element of the range.
It means for each value of x there exist a unique value of y.
In the given relation for each value of x there exist a unique value of y.
Therefore the required solution is yes and this relation is a function.
Answer:
- He must sell each CD for R1,10 to make 40% profit
Step-by-step explanation:
R40×5%=2
R40-2=R38
40%×38=R15,2
15,2+40=55,2
55,2÷50=R1,10

Answer:
nth term = 
Step-by-step explanation:
Let us assume that the given sequence is a G.P.
Now, if the first term of the G.P. is a and the common ratio is r, then
Third term = 
.......... (1) and
20th term = 
........... (2)
Now, dividing equation (2) with equation (1) we get
⇒ 
⇒ r = 1.2.
Hence, from equation (1) we get
a(1.2)² = 11
⇒ a = 7.639 (Approx.)
Therefore, the general term of the sequence i.e. nth term = (Answer)
