A +b = 90c = 1/2(86)=43
a + b + c = 133
D. 48
First is 2.05 times 20, which is 41. And then you add the 7 for tip, which is 48.

Step-by-step explanation:
Step-by-step explanation:
The midline is the average of the lowest point and the highest point.
y = (4 + 6) / 2
y = 5
The amplitude is the distance from the midline to the lowest/highest point:
a = 5 − 4 = 1, or a = 6 − 5 = 1
It's also half the distance between the lowest point and the highest point:
a = (6 − 4) / 2
a = 1
The period is the time it takes to complete a full cycle, so the period is 12 hours.
