Infinite lines of symmetry because you can make any cut on the circle and it would en symmetric with the captain America shield
68 can go into 757 11 times, the remainder would be 9
757÷68= 11 r 9 or 11 9/68
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
