Solve the problem.Find the total-profit function for the given 
and 
functions.C(x) = 50x + 275,000R(x) = 120x
A. P(x) = 70x + 275,000 B. P(x) = 275,000 - 70x C. P(x) = -70x - 275,000 D. P(x) = 70x - 275,000
Solve the problem.On a Touch-Tone phone, each button produces a unique sound. The sound produced is the sum of two tones, given by y = sin (2?lt) and y = sin (2?ht)where l and h are the low and high frequencies (cycles per second) shown on the illustration.
The sound produced is thus given by y = sin (2?lt) + sin (2?ht)Write the sound emitted by touching the 9 key as a product of sines and cosines.
A. y = 2 sin (357?t) cos (2061?t) B. y = 2 sin (2061?t) cos (357?t) C. y = 2 sin (2329?t) cos (625?t) D. y = 2 sin (625?t) cos (2329?t)
