<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.
Answer:
14
Step-by-step explanation:
10% of 35 is 3.5. 3.5 x 4 = 14
Answer:
22
Step-by-step explanation:
Boys to Girls
5 to 6
10 to ?
Since 10 is twice as much as 5, we have to multiply the number of girls by 2. 6 times 2 is equal to 12. Then, since we need to find the total number of boys and girls, we have to add both sides. 10 (boys) plus 12 (girls) equals 22.
