What would the graphs of each question look like?
Just put the equation for each question in www.desmos.com/calculator, so I can see how you graph these.
Question 1:
Question 2:
Thanks to anyone who helps!
First one
We have the form y = Asin (Bx)
A = 20/2 = 10
B = 2pi / period = 2pi / 8 = pi/ 4
C = midline = y = 0
The function is
y = 10sin [ (pi/4] x )

Second one
A = 6
The period is 20 sec
B = 2pi /period = 2pi /20 = pi/10
C = the normal midline is y = 0
The midline here is y = 10.....so C = 10
y = 6sin [ (pi/10) x ] + 10
