A CNC machine centre costs £100,000. Its value depreciates at X% per annum.

How long will it take to have a value of £50,000?

X= 1.8%

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

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
