A)
The dotted triangle is the transformed/new one and is smaller than the original figure so the dilation is a reduction.
b)
All points moved 1/3 of their distance to the center of the dilation/the origin
1-1/3=2/3 as a scale factor, or in other words if any of the original point coordinates gets multiplied by the factor 2/3 you will receive the transformed coordinates
Answer:
The answer is below
Step-by-step explanation:
The function B can be represented by the function:
B = C + Acos(Pt)
a) From the graph of the function, it starts from 30, hence it is a cosine function.
The amplitude (A) = (highest value - lowest value) / 2 = (30 - 10) / 2 = 10
A = 10
b) The function completes an oscillation every 12 months, hence its period (P) = 12
c) The average value = 10/√2
d) The vertical shift (C) is the difference between the highest and lowest value.
Therefore, C = 30 - 10
C = 20
Answer: 1.5 less than 15 is divided by a number d.

Answer:
reflect y = cos x over the x-axis
Step-by-step explanation:
When a function is reflected over the x-axis, the transformation is:
y = -f(x)
If it were reflected over the y-axis, the transformation would be:
y = f(-x)
