Answer:
y=cos(x+π)
Step-by-step explanation:
Known that the cosine function has a period of 2π.
Now, the parental function is y = cosx, which has y-intercept at y = 1, and x-intercept at π/2.
Notice that the function showed in the graph attached has y-intercept at y = -1 and x-intercept at π/2. This indicates that the function has been moved leftwards π units.
Therefore, the function that belongs to this graph is
Answer:
It's C
Step-by-step explanation:
Your graph should be this one, with both lines solid because, the X line, or red, has to be at least -1 or higher, and the Y line, or the blue, has to be +4 or higher
Answer:
A = $18,326.00
(assuming simple interest)
Step-by-step explanation:
Assuming simple interest, the following formula applies:
final amount = (principal amount) x [1 + (annual rate)(time elapsed) ]
or
A = P (1 + rt)
in our case,
P = $7,700
r = 5.75% = 0.0575
t = 24 years
hence,
A = 7700 [ 1 + (0.0575)(24)]
A = 7700 ( 1 + 1.38)
A = 7700 x 2.38
A = $18,326.00
