Answer:
A. y = cos x
Step-by-step explanation:
The function that we see graphed has the point (0,1), this means whichever trig function f(x) it represents f(0) = 1.
Now, only the cosine function has the property that cos(0) = 1, thus choice A is the correct answer.
Step-by-step explanation:
Answer:
x = 11
Step-by-step explanation:
Answer:
A. 
Step-by-step explanation:
We have been given an equation of a line in point-slope form. We are asked to write our given equation in standard form.
Since we know that standard form of equation is: 
, where, a, b and c are constants.
Let us multiply both sides of our given equation by 2.
Let us add 6 to both sides of our equation.
Let us subtract x from both sides of our equation.
Multiply both sides of our equation by -1.
Rearranging our equation we will get,
Therefore, the standard form of our given equation is and option A is the correct choice.
Answer:
50
Step-by-step explanation:
If the first statement its true (At most 0 of the statements are true), there are not true statements in the paper. So, the first statement its false.
Now, if the first statement its false, this mean there must be at least 1 true statement in the paper.
Now, if the second statement its true ( at most 1 of the statements are true) this implies that the third statement its true (if "at most 1" its true, then "as most 2" must be true).
If any statement (besides the first) its true, then all the statement that follows it must be true.
The first non false statement, then, must be the statement made by the person 51: "At most 50 statements are true"
And the 49 statements that follows are true as well.
