Cot x = cos x csc x
1/tan x = cosx (1/sin x)
1/(sin x / cos x) = cos x / sin x
cos x / sin x = cos x / sin x
The domain of validity is all real number values of x except for sin x = 0.
Answer: the number of social media advertisements that you purchased is 18
The number of newspaper advertisements that you purchased is 6
Step-by-step explanation:
Let x represent the number of social media advertisements that you purchased.
Let y represent the number of newspaper advertisements that you purchased.
You purchase three social media advertisements for every one newspaper advertisement. This means that
y = x/3
x = 3y
You end up purchasing a total of 24 advertisements. This means that
x + y = 24 - - - - - - - - - 1
Substituting y = into equation 1, it becomes
3y + y = 24
4y = 24
y = 24/4 = 6
x = 3y = 6×3 = 18
The equations are
x = 3y
x + y = 24

Answer:
- <u><em>Option A. F T → F</em></u>
Explanation:
A conditional is represented by:
Where p is called the antecedent, and q is the consequent.
Thus, a conditional states that if the antecedent is true, its consequent is also true; also, if the consequent is false, then the antecedent must be false.
On the other hand, if the antecedent is true, the consequent can be either true or false.
<u>1. State the antecedent of the conditional and is truth value</u>
- Truth value: False, because 6 is not greater than 10.
<u>2. State the consequent of the conditional and its truh value</u>
- Truth value: True, because 8 times 3 is 24.
<u>3. Truth value of the conditional</u>
Hence, the truth value of the conditional is:
Which is the option A.
