Answer:
D = 9sin(2π(t + a)/24) + 45
Step-by-step explanation:
Let's find the average temperature;
(54 + 36)/2 = 45°
Amplitude = 54 - 45 = 9
From the wave equation, we can write the temperature as;
D = 9sin(2π(t + a)/24) + 45
Where;
D is the temperature
t is the time in hours after midnight
a is a "phase" that is used to set the time at which temperature(D) occurs

Answer:
n = 16
Step-by-step explanation:
8n/9 = 6.4/0.45
Cross multiply.
0.45 * 8n = 9 * 6.4
3.6n = 57.6
n = 16
