<h3>Answer:</h3>

x/tan(x) is an even function

sec(x)/x is an odd function

<h3>Explanation:</h3>

<em>x/tan(x)</em>

For f(x) = x/tan(x), consider f(-x).

... f(-x) = -x/tan(-x)

Now, we know that tan(x) is an odd function, so tan(-x) = -tan(x). Using this, we have ...

... f(-x) = -x/(-tan(x)) = x/tan(x) = f(x)

The relation f(-x) = f(x) is characteristic of an even function, one that is symmetrical about the y-axis.

_____

<em>sec(x)/x</em>

For g(x) = sec(x)/x, consider g(-x).

... g(-x) = sec(-x)/(-x)

Now, we know that sec(x) is an even function, so sec(-x) = sec(x). Using this, we have ...

... g(-x) = sec(x)/(-x) = -sec(x)/x = -g(x)

The relation g(-x) = -g(x) is characeristic of an odd function, one that is symmetrical about the origin.

A radio station had 100 tickets to a concert. They gave away 3thimes as many tickets to listeners as to employees. How many tick
natali 33 [55]

Answer:

They gave away 75 tickets to the listeners and 25 to the employees.

Step-by-step explanation:

If you think about it the function for this would be f(x)=3x+x=100.

3x is the listeners while x is the employees. A simplified version of solving this is doing 100/4 and then 25 times 1 is 25, which is the number of tickets to emplyees.

Jk=6x, kl=3x, and jl=27
sweet [91]

I am going to assume these are points across the same line. (line segments)

If so, then jk + kl = jl

If jk is 6x and kl is 3x, we can solve for x.

6x + 3x = 27 (note we subbed 27 in for jl)

9x = 27 (divide both sides by 9 to leave on x on the left)

x = 3

CHECK! sub 3 in for x in the original problem.

6 (3) + 3 (3) = 27

18 + 9 = 27

Yes! It checks. x = 3
