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
The value of x is 2. because you rule out y so it is 6times2is 12+3. that is 15
False because 4x-3(5x-1) is -14x and 3+9x is 6x
5. 90 + 54 = 144 flowers
6. 250 - 106 = 144 balls
