Pythagorean theorem
A^2 + B^2 = C^2
30^2 + 16^2 = C^2
1156 = c^2
Square root of 1156 = c
C = 34
Therefore x = 34

Help me pleasseeeee!!! its about algebraic properties of limits!
s2008m [1.1K]

\text{Hello there! :)}

3. \sqrt{2} \\\\\text{4.  0}\\\\\text{5.  dne}

\text{To find the overall limit, they must approach the same y-value from each side:}

\\\\3.  \lim_{x \to \frac{\pi }{4} } 2sinx ={\sqrt{2}

\text{Therefore:}\\\\3.  \lim_{x \to \frac{\pi }{4} } f(x)= {\sqrt{2} }

\text{For this question, evaluate the limit from the RIGHT-HAND side:}\\\\4.   \lim_{x \to \pi +} f(x)\\\\ \text{Use the equation tanx to evaluate since it involves values greater than \pi:}\\\\

\lim_{x \to \pi +} tanx = 0\\\\\text{So:}\\\\ \lim_{x \to \pi +} f(x) = 0

5.  \\\\\text{Evaluate the overall limit. Make sure both sides approach the same y=value:}\\\\ \lim_{x \to \pi } 2cosx= -2\\\\ \lim_{x \to \pi } tanx = 0\\\\ \text{ Therefore:}\\ \lim_{x \to \pi } f(x) = dne \text{ (Does not exist})

Given that the series kcoskt kº +2 k=1 converges, suppose that the 3rd partial sum of the series is used to estimate the sum of
3241004551 [841]

Answer:

c

Step-by-step explanation:

Given that:

\sum \limits ^{\infty}_{k=1} \dfrac{kcos (k\pi)}{k^3+2}

since cos (kπ) = -1^k

Then, the  series can be expressed as:

\sum \limits ^{\infty}_{k=1} \dfrac{(-1)^kk)}{k^3+2}

In the sum of an alternating series, the best bound on the remainder for the approximation is related to its (n+1)^{th term.

∴

\sum \limits ^{\infty}_{k=1} \dfrac{(-1)^{(3+1)}(3+1))}{(3+1)^3+2}

\sum \limits ^{\infty}_{k=1} \dfrac{(-1)^{(4)}(4))}{(4)^3+2}

= \dfrac{4}{64+2}

=\dfrac{2}{33}
