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)
Answer: √90=3√5⋅2=3√10
Step-by-step explanation:
The diameter is about 1,275.4 because D=C/pi so 4007\pi=1275.4
It is 71 because 0 is less than 5, so it stays the same.
