Answer:
   quadratic
Step-by-step explanation:
The x-values are sequential, so we can look at the y-values.
Differences from one to the next are ...
   -7, -1, 5, 11, 17
And the differences of these numbers are ...
   6, 6, 6, 6
When <em>second</em> differences are constant, the sequence can be produced by a <em>second</em>-degree (quadratic) polynomial.
__
Here, that polynomial is ...
   y = 3x² +2x -1
The regression functions of a graphing calculator can help you find the appropriate formula.
 
        
             
        
        
        
Answer:
b = 90
Step-by-step explanation:
Sum the interior angles of the pentagon and equate to 540
Starting from the top and going clockwise
b + b + 45 + 90 + 2b - 90 +  b = 540 ← simplify left side
 b = 540 ← simplify left side
 b + 45 = 540 ( multiply through by 2 to clear the fraction )
 b + 45 = 540 ( multiply through by 2 to clear the fraction )
11b + 90 = 1080 ( subtract 90 from both sides )
11b = 990 ( divide both sides by 11 )
b = 90
Thus
b + 45 = 90 + 45 = 135
2b - 90 = 2(90) - 90 = 180 - 90 = 90
 b =
 b =  × 90 = 135
 × 90 = 135
The angle measure from the top clockwise are
90°, 135°, 90°, 90°, 135°
 
        
             
        
        
        
Answer:$32
Step-by-step explanation: So if the double pack of CD's is 20 dollars and that $4 less than 3/4 of the triple pack, then $20 + $4 = $24, then to find how much 1/4 of the cost is we divide 24 by 3, getting $8. Finally we multiple $8 by 4 to get $32, so the cost for a triple pack is $32.
 
        
             
        
        
        
Answer:
97.35
Step-by-step explanation:
355.5 - 235.5 -22.65 
I am subtracting 235.5 and 22.65  from 355.5 because I am spending that much money on the things.
=> 355.5 - 235.5 - 22.65
=> 120 - 22.65
=> 97.35 rupees
So, 97.35 rupees is left
