What is the solution of log z + 12 = 9?
1,000
-0.001
0.001
-1.000
Done

z =0.001

Step-by-step explanation:

log z + 12 = 9

Subtract 12 from each side

log z + 12-12 = 9-12

log z = -3

Raise each side to the base of 10

10^ log z = 10 ^-3

z = 10 ^-3

z =0.001

here

step-by-step explanation:

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
