Answer:
hey! been a while since I've answered questions haha
typically I would put an explanation for my answers but this one's pretty straightforward so ¯\_(ツ)_/¯
a) mode is the number that occurs most often in a data set.
b) mean is the average or expected value in the data set
c) median is the value that lies in the midpoint in the data set.
For this case we have:
By trigonometric property we have:

Where:

Substituting:

Clearing x we have:

Thus, the equation is:

If you're just starting calculus, perhaps you're asking about using the definition of the derivative to differentiate
.
We have

Expand the numerator using the binomial theorem, then simplify and compute the limit.

In general, the derivative of a power function
is
. (This is the aptly-named "power rule" for differentiation.)
Answer:
You can put this solution on YOUR website! 5X - 20 = 10 * X 5X - 20 = 10X Subtract 5x from each side-20 = 5X Divide each side by 5-4 = X. Let's make sure it works... 20 less than five times a number (-20-20) is equal to the product of ten and that number (10 * -4)
Step-by-step explanation:
