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:
option a is right.
Step-by-step explanation:
because u can also check by putting the value of x = 5.25 .it satisfies both sides.
Answer is 695
(365+1025)/2= 695
Answer is 44-2/5
Step by step. I did a print screen showing how we can use cancellation with the 3 and 9 so the numbers are smaller. Then we multiplied across to get 222/5.
Divide 222 by 5 = 44-4/10, simplified to 44-2/5.
