Answer:
Step-by-step explanation:
It would be 8.20 because the 10 place is higher than the 10 place in 8.002
 
        
             
        
        
        
Answer:
Not sure if this is what you mean but it might be 4 * 7 = 28

Caitlin = 20 laps
Hannah = 4/5 as many laps
Multiply the laps swan by Caitlin (20) by 4/5
20 x 4/5 = 80/5 = 16
Hannah swam 16 laps
 
        
             
        
        
        
Answer:
(x²/4) + (y²/16) ≤ 1
Step-by-step explanation:
The general form of the ellipse in the graph is 
x²/4 + y²/16 = 1
we want to find the inequality which represents the shaded area this will determine whether which of the following 2 choices are correct 
Choice 1: x²/4 + y²/16 ≥ 1
Choice 2: x²/4 + y²/16 ≤ 1
we note that point (0,0) lies inside the shaded area. Which means if we substitute (0,0), it should create an equality that is valid.
try choice 1: 0²/4 + 0²/16  = 0 ≥ 1 (not valid because obviously zero is smaller than 1)  
try choice 1: 0²/4 + 0²/16  = 0 ≤ 1 (this is valid, hence choice 2  is the answer) 
 
        
             
        
        
        
Answer:
A rational expression that has the nonpermissible values  and
 and  is
 is  .
.
Step-by-step explanation:
A rational expression has a nonpermissible value when for a given value of  , the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
, the denominator is equal to zero. In addition, we assume that both numerator and denominator are represented by polynomials, such that:
 (1)
 (1)
Then, the factorized form of  must be:
 must be:
 (2)
 (2)
If we know that  , then the rational expression is:
, then the rational expression is:
