Answer:
y = 0
Step-by-step explanation:
Since there is no indication of a shift in the graph of f(x) = 3cos(-0.25x), then the midline must be the normal midline for a cosine or sine function which is: y = 0.

Pictures ? Or anything where’s the rest of the work I can help you
Interest = principle * rate * time...
I = PRT...we are going to rearrange this because we are looking for the principle...
I / (RT) = P
I = 22.40
R = 2.8%...turn to a decimal = 0.028
T = 1
sub and solve
22.40 / (0.028(1) = P
22.40 / 0.028 = P
800 = P....amount of original deposit is $ 800 <==
Answer:
D. y+15 = 4/5(x+5)
Step-by-step explanation:
A line contains the points (8,9) and (-12, -7).
(y2 - y1) = m(x2 - x1)
(9 - (-7))= m (8 -(-12))
16 = m*20
m = 16/20 = 4/5
Given line has slope m= 4/5.
Parallel line has the same slope m = 4/5.
Point-slope equation is (y - y1) = m(x - x1).
We have slope m = 4/5, and point (-5, -15).
So,
(y - (-15)) = 4/5(x - (-5))
y+15 = 4/5(x+5)
