Answer:
x = 0°
Step-by-step explanation:
Given
- 2 + 6cosx = 8 - 4cosx ( add 4cosx to both sides )
- 2 + 10cosx = 8 ( add 2 to both sides )
10cosx = 10 ( divide both sides by 10 )
cosx = 1 , thus
x = (1) = 0° for 0° ≤ x ≤ 180°
Here they are:

Answer:
The balance in her lunch account at the end of the day on Friday is -$1.15.
Step-by-step explanation:
The balance at the end of the week will be the result of adding up the initial balance with the amount deposited on Monday minus the total amount spent that week.
Initial balance=$2.60
Amount deposited on Monday=$20
Total amount spent that week=$4.75*5=$23.75
Balance=$2.60+$20-$23.75
Balance=$22.60-$23.75
Balance=-$1.15
According to this, the answer is that the balance in her lunch account at the end of the day on Friday is -$1.15.
The correct answer is option A which is x > 0 The domain of the given function will be greater than zero.

What is a function?</h3>
A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given function:-
F(x) = 3 - ( 1 )
The function will give results for all the values greater than zero. As we put the input values in the function we will get the output.
At x = 1 F(x) = 3 - ( 1 )¹ = 3 - 1 = 2
At x = 2 F (x ) = 3 - ( 2 )² = 3 - 1 = -1
Therefore the correct answer is option A which is x > 0 The domain of the given function will be greater than zero.
