It sounds like <em>R</em> is the region (in polar coordinates)
<em>R</em> = {(<em>r</em>, <em>θ</em>) : 2 ≤ <em>r</em> ≤ 3 and 0 ≤ <em>θ</em> ≤ <em>π</em>/2}
Then the integral is

 
        
             
        
        
        
5=.1*x
divide both side by .1
5/.1=x
x=50 dollars
        
                    
             
        
        
        
Answer:j
Step-by-step explanation:
If it’s closed it would be greater than -2 but since it’s open it’s equal or greater than 
 
        
             
        
        
        
First definition matches with expression, second matches with equation ,third matches with algorithm and fourth matches with equation.
Given  four definitions of equation, expression, algorithm but mixed.
We have to match the definitions with appropriate term.
We know that expression is a combination of numbers, symbols, fraction, coefficients, indeterminants mostly not found in equal to form. It exhibits a behaviour only.
Algorithm is a computer programming to do a specific task in a predetermined way.
Equation is a relationship between two variables expressed in equal to form. In this we have to put the value of variables and the equation gives us a value.
Hence  First definition matches with expression, second matches with equation ,third matches with algorithm and fourth matches with equation.
