Simple you just solve for y and put the equation in slope-intercept form
Answer:
y = 4 sin( 0.5t -
) - 2
y = a sin ( 2t -
) + 2
Step-by-step explanation:
In the first question,
amplitude = 4
Period = 
phase shift = 
Vertical shift = -2
Angular velocity , w = 
Here, w =
= 0.5
The general equation of a wave is
y = a sin( wt + ∅ )
Putting above values in the equation,
y = 4 sin( 0.5t -
) - 2
In the second question,
Amplitude is not given so we will take it as a.
time period = 
w = 2
Phase shift = 
Vertical shift = 2
The equation is
y = a sin ( 2t -
) + 2
Answer:
Total money earned = £1,947.35
Step-by-step explanation:
Given:
Per ticket cost = £3.95
Number of rows = 17
Number of seats in each row = 29 seats
Find:
Total money earned.
Computation:
Total number of seats = Number of rows × Number of seats in each row
Total number of seats = 17 × 29
Total number of seats = 493 seats
Total money earned = Total number of seats × Per ticket cost
Total money earned = 493 × £3.95
Total money earned = £1,947.35
First Answer and Last Answer are correct.
The two middle should be reconsidered, you can't really tell if they are technically Perpendicular.
So the correct answer should be "Can't be determined" for the middle two.
Answer:
The answers are 54 degrees and 234 degrees
Step-by-step explanation:
mathematically we have the tan positive on only two axes
these are the first (0-90) degrees and the 3rd quadrant (180-270)
We start by find the arc tan of the angle value
Thus;
x = arc tan (1.3562)
x = 54 degrees
On the third quadrant, we have it that;
180 + 54 = 234 degrees
