Answer:

Step-by-step explanation:

sin2x = 2sinx*cosx

         = 2\sqrt{sin^{2}x } * cosx

         = 2\sqrt{(1-cos^{2}x } * cosx

         = 2  \sqrt{1-\frac{3}{5} ^{2} } *\frac{3}{5}

         = \frac{8}{5}  * \frac{3}{5}  

         = 24/25

The table shows the outputs, y, for different inputs, x: Input (x) 8 12 14 16 Output (y) 8 12 16 16 Part A:Do the data in this t
Nataly_w [17]
A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones.

B. table : (8,8)(12,12)(14,16)(16,16)
                look at ur points...when x = 8, y = 8...so the table, when x = 8 has a 
                value of 8
relation : f(x) = 8x - 5....when x = 8
              f(8) = 8(8) - 5
              f(8) = 64 - 5
              f(8) = 59....and the relation has a value of 59
Therefore, the relation has a greater value when x = 8 <==

C. f(x) = 8x - 5...when f(x) = 19
     19 = 8x - 5
      19 + 5 = 8x
     24 = 8x
     24/8 = x
     3 = x <==
