Answer:
The question is incomplete, so I will describe the sine regression model.
The function
y = 0.884 sin(0.245x - 1.093) + 0.400
correspond to the general equation:
y = a sin(bx - c) + d
where:
a = 0.884
b = 0.245
c = 1.093
d = 0.400
The amplitude of the function is computed as follows:
amplitude = |a| = 0.884
The period of the function is computed as follows:
period = 2π/|b| = 25.6456
The phase shift of the function is computed as follows:
phase shift = c/b = 4.4612 to the right (because there is a minus sign before c in the equation)
The vertical shift of the function is computed as follows:
vertical shift = d = 0.400
The answer would have to be
D
Answer: $6.66
Explanation:
3.70 multiplied by 0.80 = 2.96.
3.70 + 2.96 = $6.66
2km=2000m
25m=25m
2500cm=25m
3000mm=3m
Hence the longest is 2km=2000m
(y2-y1)/(x2-x1)=
slope: 21/26
