f(x) = 9x^10 tan^−1 x is a product: f(x) = (9) * (x^10) * (arctan x).
Use the product rule: (d/dx) (u*v) = u*dv/dx + v*du/dx and the inverse tangent rule:
(d/dx)(arctan x) = 1 / (1 + x^2).
Then the desired derivative is:
1
f '(x) = 9 [x^10*----------- + arctan x*10x^9 ]
1+x^2
Note that x^9 can be factored out:
x
f '(x) = 9*x^9 [ ----------- + 10arctan x ]
1+x^2
Answer:
0.1
Step-by-step explanation:
There are ten tiles and one G and 0.1 is a tenth of one, so your chances are 1 in 10
I’m not so sure, whether I understood the question. But I think you will read it seven hundreds seventy times 6 equals to seventy seven times six times hundred. In addition, the answer is 4,620 and it can be read four thousand six hundred twenty.
Answer:
<u><em>Measure of angle A is 27 7/9 degrees.</em></u>
Step-by-step explanation:
Lets call measure of angle A is <em><u>X-10</u></em>
Lets call measure of angle B is X
Lets call measure of angle D is 2.5X+20
We know that the sum of triangles add up to 180 degrees
X+X-10+2.5X+20=180
X=37 7/9
So measure of angle A is 27 7/9 degrees.
I hope this is right. :)
Solution: The standard deviation is used in conjunction with the mean to numerically describe distributions that are bell shaped. The mean measures the center of the distribution, while the standard deviation measures the spread of the distribution.
In normal distribution (bell shaped distribution) , the mean and standard deviation are used to describe its distribution. The mean measures the center of the distribution, while the standard deviation takes care of the spread of the distribution.
The mean of the normal distribution is and the standard deviation is
