Solve the problem.On a Touch Tone phone, each button produces a unique sound. The sound produced is the sum of two tones and is given by 
and y = sin (2?ht), where l and h are the low and high frequencies (in hertz = Hz) associated with that button. 
The tone produced is thus given by y = sin (2?lt) + sin (2?ht). Write an expression that models the tone by pressing the "5" button as a product of sines and cosines.
A. y = 2 sin (2247?t) cos (707?t) B. y = 2 sin (707?t) cos (2247?t) C. y = 2 sin (566?t) cos (2106?t) D. y = 2 sin (2106?t) cos (566?t)
