thankyou for reviewing my answers! Have a good day(:
Hey...it looks like nothing has appeared in the question...maybe something is wrong?
First one ....correct !!!
Notice that we can write this as :
f(x) = Asin B(x - C) + D
f(x) = 33 sin 7 (x - pi/84) + 33
Only B affects the period......
"B" tells us how many periods are in 2pi sec
So we can find the period (in sec) thusly :
B = 2pi / period
7 = 2pi / period rearrange as
period = 2pi/7 ≈ .897 sec = .90 sec → correct !!!!
