A machine produces 90 decibels of sound power. The inequality 90 + 10 log x ≤ 95 represents the number of identical machines, x, that can be used at the same time and produce less than 95 decibels of sound power. What is the maximum number of machines that can be used at the same time and produce less than 95 decibels of sound power?

Step-by-step explanation:

I plugged it into desmos and it said it can go up to 3.16 but you can't have 3.16 machines so it's 3.

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
