Answer:
The square root of 0.33 is the only irrational number.
Step-by-step explanation:
.25 NOT
sq rt. of .25 is .5
sq rt. of .33 is .574456....
 
        
             
        
        
        
The question is asking which formula will give the results
1, 9, 36, 100, 225, ...
for k values of 
1, 2, 3, 4, 5, ...
You can try them out to see.
A) for k=2, gives 2*3/2 = 3 . . . not 9
B) for k=1, gives 2^3/3 = 8/3 . . . not 1
C) for k=2, gives (2^2*3^2)/4 = 9 . . . . looks promising
D) for k=1, gives 1*2^3/5 = 8/5 . . . not 1
Selection C is the only viable choice. (And the correct one.)
 
        
        
        
We have that Clarence sells yearly subscriptions to a particular magazine.
He sells at least 10 and not more than 25 subscriptions each week.
The function f(t) = 48t represents the amount of money earned for selling t subscriptions each week.
So;
10 ≤ t ≤ 25
f(t) therefore is 48(10) ≤ f(t) ≤ 48(25)
This gives: 480 ≤ f(t) ≤ 1200
So the amount of money earned f(t) for selling t subscriptions each week is all multiples of 48 between 480 and 1200, inclusive. 
 
        
                    
             
        
        
        
Step-by-step explanation: If you take a look at the right side of the equation, a 3 is being added to our variable <em>x</em>.
If you were going to solve this equation, you must subtract 3 from the right side and the left side to isolate our variable.
You would end up with 4 = x.
