Answer:
Step-by-step explanation:
<u>Given:</u>
- Volume of fuel = 5/6
- Volume of fuel used each time = 1/12
- Number of travels to or from work = x
<u>Since each time 1/12 of the tank is used, and initial volume is 5/6 of the tank, the equation will be:</u>
<u>Solving the equation we get:</u>
So Felitz can travel 10 times to/from work with 5/6 full tank
Since , it follows that , , and .
Then
and the pattern repeats. The value of boils down to finding the remainder upon dividing by 4.
We have
so that
and so the answer is C.
Answer:
y = 0
Step-by-step explanation:
The given sinusoidal equation is
The general form of the sin function is presented as follows;
y = A·sin(B·(x - C)) + D
Where;
A = The amplitude
The period, T = 2·π/B
The frequency, f = B/2·π
C = The horizontal shift
D = The vertical shift
By comparison with the given sine function, we have;
The amplitude, A = 2
The frequency, f = B/2·π = π/2/(2·π) = 1/4
The frequency, f = 1/4 Hz
C = The horizontal shift = 3/(π/2) = 6/π
The vertical shift, D = 0
Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function, , is therefore, the line;
y = 0.
