6. multiply the following expression: ( 5 – 2i) (3 +i).
우부우부
foil
5
]
5

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
