Answer:
72 cm^3
Step-by-step explanation:
find the volume of the big block and the volumem of the smaller block and subtract it 
(8 x 2 x 5) - (2 x 2 x2)
= 80 cm^3 - 8 cm^3 
= 72cm^3
 
        
             
        
        
        
Splitting up [0, 3] into  equally-spaced subintervals of length
 equally-spaced subintervals of length  gives the partition
 gives the partition
![\left[0, \dfrac3n\right] \cup \left[\dfrac3n, \dfrac6n\right] \cup \left[\dfrac6n, \dfrac9n\right] \cup \cdots \cup \left[\dfrac{3(n-1)}n, 3\right]](https://tex.z-dn.net/?f=%5Cleft%5B0%2C%20%5Cdfrac3n%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac3n%2C%20%5Cdfrac6n%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac6n%2C%20%5Cdfrac9n%5Cright%5D%20%5Ccup%20%5Ccdots%20%5Ccup%20%5Cleft%5B%5Cdfrac%7B3%28n-1%29%7Dn%2C%203%5Cright%5D)

Answer:

Step-by-step explanation:
Anything set to equal <em>x</em> is considered an undefined <em>rate of change</em> [<em>slope</em>], which is a <em>vertical line</em>. This is not a function, since it flunks the <em>vertical line test</em>.

I count five 'k's there, so that part of the expression is
                                     k⁵  .
Two 'n's form the rest of it, so that part is  n² .
The parts are multiplied, so the simplest form of the expression is
                                     k⁵ n²  .
