Answer:
14/15
Step-by-step explanation:
7/6 x 4/5 = 28/30
(you multiply the numerators and the denominators each so 7 x 4 = 28 and 6 x 5 = 30.)
simplify
14/15
Answer:
D) 132°
Step-by-step explanation:
8x+12=5x+57 subtract 5x from both sides
3x+12=57 subtract 12 from both sides
3x= 45 divide by 3 from both sides
X=15
5(15)+57=132°
Answer:
No
Step-by-step explanation:
Because they are not proportional they do are not a multiple of each other
Given the function:

Let's find the amplitude and period of the function.
Apply the general cosine function:

Where A is the amplitude.
Comparing both functions, we have:
A = 1
b = 4
Hence, we have:
Amplitude, A = 1
To find the period, we have:

Therefore, the period is = π/2
The graph of the function is shown below:
The parent function of the given function is:

Let's describe the transformation..
Apply the transformation rules for function.
We have:
The transformation that occured from f(x) = cosx to g(x) = cos4x using the rules of transformation can be said to be a horizontal compression.
ANSWER:
Amplitude = 1
Period = π/2
Transformation = horizontal compression.
