I know, you have to divide 90 by what ever the length is, then you have to figure out where the points are. So it should be.... D!!!
Answer:
option C is the correct answer
Step-by-step explanation:
The trigonometric equation you are using has a general form
y = A* tan w*(x - r)
Where
A is the amplitude of the function
w is the frequency rad/s
r is the phase shift
In your case
A = -2
The frequency is
w = (2*pi)/period
period = pi/4
w = 8
r = -pi/2
y = -2* cos 8*(x + pi/2)
Me just so I can ask a question
Answer:11,256
Step-by-step explanation:
Matt would get about $4 and 90 cents back from the clerk, since 10 dollars minus $5 and 10 cents equals $4 and 90 cents.
