Solve.In a distant galaxy the gravity of planet A is 216 times as strong as the gravity of planet B, so objects on planet A weigh 216 times as much as they weigh on planet B. If the object weighs 
on planet A, how much does it weigh on plant B?
A. 1600 lb.
B. 153 lb.
C. 170 lb.
D. 160 lb.

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)
