The graphed cosine function can either be:
cos(x + pi) or cos(x - pi).
<h3>
Which is the equation of the graphed function?</h3>
We know that this function is a cosine function with a phase shift, so the general form is:
f(x) = cos(x + P).
Where P is the phase shift.
In the graph we can see that when x = 0, f(0) = -1
And we know that cos(pi) = -1 = cos(-pi)
Then we must have that:
f(0) = cos(P) = -1
By what we wrote above, we know that P can be either -pi or pi (because of the parity of the cosine). Let's say that P = pi, then the cosine function is:
f(x) = cos(x + pi).

Well would need to subtract 10-5/8 so you would need to change the 10 into a improper fraction then subtract the fractions Hope this help
400 inches because there are four sides so you would have to divide by 4
Answer:
either 76 or 19
Step-by-step explanation:
76 if it's 1/5 of the original amount as well as 3/4 the original amount
1/5+3/4=19/20
3.80=1/20x
3.80+19/20x=76
3.8*20=76
19 if it's 1/5 of the original amount and 3/4 of the new amount
3.80=1/4y
3.80+3/4y=15.20
15.20=4/5x
15.20+1/5x=19
