Answer:
The correct option is;
f(x) = 3·sin x/8·π + 2
Step-by-step explanation:
The given parameters for the sinusoidal function are;
Amplitude of oscillation = 3
Frequency of oscillation = 1/8·π
Midline of oscillation= 2
The general form of sinusoidal equation is y = A·sin(B(x - C)) + D
Where;
A = The amplitude
B = The frequency
C = The horizontal shift
D = The midline or vertical shift
Substituting the given values into the general form of sinusoidal equation, we have;
f(x) = y = 3·sin(1/8·π(x - 0)) + 2 = 3·sin(x/8·π) + 2
Which gives;
f(x) = 3·sin(x/8·π) + 2.
If the transformation will result to an after-image that not is congruent to the original figure, then the transformation is most probably a dilation. Amon the choices, the answer must be
<span>a reflection across the y-axis followed by a dilation with a scale factor of 0.5

Answer
39 bills of 1$
16 bills of 10$
Step-by-step explanation:
x-nr of $1
y-nr of $10
x*1+y*10=199
x+y=55 , x=55-y
so I use the substitution method
(55-y)*1+10y=199
55+10y-y=199
-55 -55
9y=144
y=144/9
y=16
so x=55-16
x=39
verify 16*10+39*1=160+39=199
Solution:
we have been asked to find a function for the given sitatution
The given situation is
A movie store sells DVDs for $11 each. what is the cost C of n DVDs.
Cost of 1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.
Cost of 1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.
......................................................................................................................
.......................................................................................................................
Cost of 1 DVD is $11, then the cost of n DVDS will be nx11=$11n.
Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.
Hence the correct option is C=11n, Discrete.
