Cotx = Cosx/sinx
1/Cotx = sinx/cosx
Sinx + cosx *1/cotx = sinx + cosx * sinx/cosx = 2sinx

Answer: 1 
Step-by-step explanation:

Answer:
P=163,487,500
Step-by-step explanation: P=Ae^(kt)
151000000=145000000*e^(k5)
151000000/14500000=e^(k5)
1.04137931=e^(k5)
Ln 1.04=Ln e^(k5)
0.04=k5
k= 0.008
P=145,000,000*e^(.008*15)
P=145,000,000*e^0.12
e=2.71828
P=145,000,000*1.12749685
p=163,487,500
