Answer:
6
Step-by-step explanation:
Deisha's build rate = 1 fence per 15 hours = 1/15 fences per hour
Travis's build rate = 1 fence per 12 hours = 1/12 fences per hour
Working together, their combined rate is 1/15 + 1/12 = 3/20 fences per hour
So it takes them 20/3 = 6 2/3 hours per fence
Step-by-step explanation:
1. Amplitude = 1. g(x) = 1 sin(6x). The coefficient 1 is the amplitude. The range of the function is or, in interval notation, [-1, 1]
2. The period is .
x-intercepts (at the beginning, middle, and end of the period)
Maximum (1/4 of way through period)
Minimum (3/4 of way through period)
