Answer:
This is simple, I would love to help. The answer is 505
Step-by-step explanation:
first, you cut the irregular shape into two rectangles, so one measures 15 by 33 and one measures 2 by 5. next, multiply 15 and 33. it equals 495. also multiply 2 and 5. it equals 10. add 495 and 10 together. 505
Answer:
x + 2tan X . sec X / X
Step-by-step explanation:
The derivatives of trigonometric functions is as follows
* d/dx (sin x) = cos x
* d/dx (cos x) = - sin X
* d/dx (tan x) = sec ^2 X
* d/dx (Cot x) = -cosec^2 X
* d/dx (sec x) = tan x . sec x
* d/dx (cosec x) = -cot x . cosec x
and so the derivative of sec is tanx . sec x
d/dx x - sec x
the derivative of variables is considered 1.
since we remove 1 from their exponent they'll have 0 as their exponent which can only mean the end value is 1.
so d/dx of X is = 1
d/dx od -sec X is = -tan X . Sec X based on the general derivative properties above.
in conclusion the final answer is = x + 2tan X . sec X / X
Answer:
Step-by-step explanation:
First, as you can see, the sequence is alternating its sign everytime, so you can deduce this term:
The sequence start from 3, and the following terms are the product between 3 and . Take a look:
For n=1
For n=2
And so on...
Let's verify the formula including all terms:
Since the sequence start from 3, we must change the 3 for -3. Because is always negative for the first term:
For n=1
For n=2
For n=3
For n=4
So, one possible sequence is:
And the serie would be given by:
