Answer: D. SRT
Step-by-step explanation:
Answer: well it depends on what you are aiming for I would say 3 or 5 as there is a 15 so maybe it would want you to divide or multiply I am only in 7th grade but I hope this helps
Step-by-step explanation:
15/3=5 15/3=5
Answer: OPTION B.
Step-by-step explanation:
Below are some transformations for a function f(x):
1. If 
and 
, the function is compressed horizontally by a factor of 
.
2. If and 
, the function is stretched horizontally by a factor of .
3. If 
and 
, the function is compressed vertically by a factor of "b".
4. If and 
, the function is stretched vertically by a factor of "b".
In this case you have the function f(x):
And the function g(x):
So, you can identify that:
and
Therefore, the graph of the function g(x) is a vertical compression of the graph of function f(x).
N=m-a just move the variable around or if there are numbers put them in the equation
Answer:
2√5
cos x = -------------
5
Step-by-step explanation:
If tan x = 1/2 then what is cos x?
Recall that tan x is defined as the quotient sin x / cos x, so that in this case sin x / cos x = 1 / 2 = opp side / adjacent side. Also, recall that cos x = adj side / hypotenuse.
To determine cos x, we need to find the length of the hypotenuse. That, in turn, through use of the Pythagorean Theorem, is √(1^2+2^2), or √5.
Then cos x = adj side / hyp = 2/√5. Rationalizing the denominator, we get
2√5
cos x = -------------
