The average temperature, in °F, of City B is given by the equation:y=19.5sin(pi/6t-2.06)+62 , where t is the time in months and t = 1 corresponds to January. What is the average temperature in April? Round your answer to the nearest hundredth.

Answer 1

in April t = 4
y = 19.5 sin (4 pi/6 -2.06) + 62
y = 62 + 19.5 sin (.0344)
y = 62 + 19.5 sin (1.97) my calculator does degrees
y = 62.67

Answer 2

Thankyouuu!
