Answer:
Assuming the 19 stood for an exponent, q = 1.098...
Step-by-step explanation:
Plugging in
in the graphical calculator, we can see that the solution is approximately q=1.098. There are no ways of solving this equation algebraically.
The radius is 10 divide by 2 which is 5?
Answer:

Step-by-step explanation:
Given :-
The sum of two numbers is 1 .
The product of the nos . is 12 .
And we need to find out the numbers. So let us take ,
First number be x

Answer:
The decibel range is 
Step-by-step explanation:
Let
d -----> the decibel level of the music
we know that
The absolute value of the difference of the decibel level of the music and its average, must be less than or equal to 28 decibels
so
The absolute value that represent this problem is

Solve the absolute value
<em>First solution (positive)</em>

Adds 110 both sides


<em>Second solution (negative)</em>

Multiply by -1 both sides

Adds 110 both sides


therefore
The decibel range is
