Answer: Love bird is 4 inches long.
Step-by-step explanation:
Given: The body of a great roadrunner is 16 in. Long and the tail is 8 in.
Also, Total length of a great roadrunner is = 4 x (length of lovebird).
It implies, length of lovebird =
Hence, Love bird is 4 inches long.
We have been given that a cosine function is a reflection of its parent function over the x-axis. The amplitude of the function is 11, the vertical shift is 9 units down, and the period of the function is . The graph of the function does not show a phase shift. We are asked to write the equation of our function.
We know that general form a cosine function is , where,
A = Amplitude,
= Period,
c = Horizontal shift,
d = Vertical shift.
The equation of parent cosine function is . Since function is reflected about x-axis, so our function will be
.
Let us find the value of b.
Upon substituting our given values in general cosine function, we will get:
Therefore, our required function would be .
