Answer:
As cosine returns a value between -1 and 1, the amplitude will simply be the coefficient of the cosine function. In this case it's 2.3, which tells us that the amplitude is also 2.3
Answer:
The correct answer is A.
Step by step:
Here is A: 4x > 22; x = 5.8
First, you replace the x with 5.8.
Since the 4 and the x are touching that means to multiply.
So, multiply 4 and 5.8 which results in 23.2.
If you replace the 4x with 23.2 this statement is true meaning that A is the correct answer for this problem.
Answer:
x= 2.5
Step-by-step explanation:
7x-5x = 2x
2x-2 = 3
3 + 2 = 5
2x=5
5/2 = 2.5
