The total sound power, in decibels, from x objects each producing 50 decibels of sound power is given
by the function f(x) = 50 + 10 log x. Suppose each of
the x objects increases its sound power by 10
decibels, so that the new total sound power, in
decibels, is given by the function g(x) = f(x) + 10.

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.

step-by-step explanation:

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .
