To answer this question, we need to pose the problem algebraically as follows:
1. The sum of two numbers is -29:
2. The difference of the two numbers is -13:
Then, we have a linear system of equations, and we can solve it by elimination, substitution, as the most suitable for this case. Then, we have that we can sum both equations and we get:
Thus, we have that the value for x = -21. We can use the first equation to substitute this value of x to find the value for y. Then, we have:
Therefore, the two numbers are -21 and -8.
We can check this as follows:
1. -21 + (-8)= -21 -8 = -29
2.-21 -(-8) = -21 + 8 = -13
Seeing as how its isocoles, the boytom two angles combine to 84 degrees. leaving 276 degrees in the upper angles or 138 degrees to each angle. c= 276 and w=59
(2/3) / (3/4) =
2/3 * 4/3 =
8/9 <==
Answer:
In this case, if you sum the first seven terms of your sum, you get 0.0002, that means that your error is less than 0.00002 , in other words, if you sum 6 terms of your sum, 4 terms of your result are correct, (because the error is less than 0.00002).
Step-by-step explanation:
Remember what the alternating series theorem says, basically it states that for a convergent alternating series .
The error of the series can be estimated as follows
The meaning of the theorem is that is an upper bound of the n-error of your sum.
In this case, if you sum the first seven terms of your sum, you get 0.0002, that means that your error is less than 0.00002 , in other words, if you sum 6 terms of your sum, 4 terms of your result are correct, (because the error is less than 0.00002).
