Express the interval set builder notation

Mathematics
1 answer:
Ivenika [448]3 years ago
7 0

Answer:

{x | -1 < x ≤ 2}

Step-by-step explanation:

Interval given in the notation of (a, b) denotes,

Upper limit at 'b' and lower limit at 'a'

Sign () denotes the interval between a and b exclusive of the numbers a and b.

Interval given as [a, b] represents,

a = lower limit

b = higher limit

Notation of [] show the interval inclusive of these numbers.

Given set in the question is (-1, 2]

Here (-1) is the lower limit and 2 is the upper limit.

(] notation shows exclusive of (-1) and inclusive of 2.

Therefore, solution set in set-builder notation will be {x | -1 < x ≤ 2}

Rectangle is 2/5 in. long and 1/3 in. wide.
VARVARA [1.3K]
Answer:  "<span>\frac{2}{15}   in²</span> " . {that is:  " (2/15) in² . "}. 
___________________________________________
Explanation:
___________________________________________
The formula/equation for the Area of a rectangle:  

A = L * w  ;  

       in which:   L  =  <span>⅖ in ; 
</span>                       w =  ⅓ in;
___________________________
Find the area;  in a "fraction value" ;
_______________________________
   A = L * w    ;  
 
          →  Substitute the given values for "L" (length) and "w" (width);
       and solve for "A" (area) in the "form of a fraction:
__________________________________________________

A   = (2/15) in  *  (1/3)  in ;
 
→ A    = [(2*1) / (5*3)] *  in * in ; 
______________________________________________________
→  Answer:  The area is:  " \frac{2}{15}   in² " .
                                          
                                             {that is, "(2/15) in² " .}.
