Answer:
The answer is below
Step-by-step explanation:
The function B can be represented by the function:
B = C + Acos(Pt)
a) From the graph of the function, it starts from 30, hence it is a cosine function.
The amplitude (A) = (highest value - lowest value) / 2 = (30 - 10) / 2 = 10
A = 10
b) The function completes an oscillation every 12 months, hence its period (P) = 12
c) The average value = 10/√2
d) The vertical shift (C) is the difference between the highest and lowest value.
Therefore, C = 30 - 10
C = 20
Answer:
No solution
Step-by-step explanation:
we have

Apply distributive property left side


subtract 2x both sides
------> is not true
therefore
The system has no solution (two parallel lines)
The answers are:
____________________________________________
[A]: f(x) = -8 ; AND:
[B]: f(x) = -3 .
______________________________________________
4J-7S
21/7=3
multiply both sides by 3
12J-21S
