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.
Answer:
im pretty sure #9 is just y=7x... it should be parallel with y=7x-3 since it has y intercept of 0 rather than -3.
Answer: 5 + 0.5m
Step-by-step explanation:
Let the number of miles be represented by m.
Therefore, since there's a $5 flat rate and an additional $0.50 per mile, this can be formed into a equation as:
= 5 + 0.5m
For example if the number of miles taken is 100miles, the amount charged will be:
= 5 + 0.5m
= 5 + 0.5(100)
= 5 + 50
= $55
Answer: 504.91 miles
Step-by-step explanation:
From the question, we are told that Trevon and his friends are going on a road trip that is 594 7/25 miles long and that they have 89 37/100 miles to reach their destination. To know how far that they've already traveled, we subtract 89 37/100 from 594 7/25.
= 594 7/25 - 89 37/100
Since the answer should be in decimal, we can change the fractions to decimal.
= 594 7/25 - 89 37/100
= [594 +(7/25 × 100)] - [89 + (37/100 × 100)]
= (594 + 0.28) - (89 + 0.37)
= 594.28 - 89.37
= 504.91 miles
They've already travelled 504.91 miles
