Answer:
V = 137.2
Step-by-step explanation:
We are given the volume equation. Simply plug in your <em>r</em> into the equation and calculate and you should get 137.189 as your answer.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
y = ax² + bx + c 
~~~~~~~ 
(4, - 2), (8, 6), (2, 0) 
a(4²) + b(4) + c = - 2 
a(8²) + b(8) + c = 6 
a(2²) + b(2) + c = 0 
16a + 4b + c = - 2 .............. <em>(1)</em> 
64a + 8b + c = 6 ............... <em>(2)</em> 
4a + 2b + c = 0 ................. <em>(3)</em> 
a = 0.5 ; b = - 4 ; c = 6 
<em>y = 0.5x² - 4x + 6</em> 
Part A: (0, 6), (6, 0) 
Part B: (0,6) 
Part C: (6, 0) 
Part D: [ 4, ∞ ) 
 
        
             
        
        
        
Answer: Our required equation would be 
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x
 
        
             
        
        
        
Answer:
Mochi
Step-by-step explanation:
Mochi 
Each week theres a increase of 4 in Mochi's weight. So you will add 4 twice to get to the 5th week. 
4th week : 17
5th week : 21
Kappa
In 4 weeks Kappa weighed 14, which is less that Mochi at the pace Kappa is going at. 
on the 3rd week Kappa weighed 11
 and 2nd week Kappa weighed 5
and 1st week Kappa weighed 3
Looking at the graph, we can give a rough estimate on the 5th week it's going to be 16 or 17 either way making Mochi heavier. 
 
        
             
        
        
        
V=(4/3)(pi)(r^3)
V=(4/3)(pi)(8^3)
V=(4/3)(pi)(512)
V=(2048/3)(pi), or around 2144.660585
