How to show that the sequence converges to M? [closed]

how to show that the sequence converges to M?
Sea I:=(a,b) supongamos que f:I→R es continua y que f(x)≥0 para x∈R
si M:=supf(x):x∈I
Demostrar que la sucesión (∫ba(f(x))n)1n converge a M.

SVG files are not visible in Apple products [closed]

I created a repo in GitHub to dynamically generated the user’s latest Medium articles on the user’s GitHub READMEs. The output of the generated SVG could view by this link. GitHub Repo link. But the Output is not visible on Apple devices. Anyone, please help me to solve the issue.

When X, Y and Z are elements of the set of whole numbers, why is (-X % Y) + Z % Y congruent to (Z – X) % Y [closed]

Studying polyalphabetic substitution ciphers, and I noticed this relationship between the decryption function and became curious.

combinatorics – Closed formula to $N:=sum_{j=0}^{k/2}left(begin{array}{c} n \ k-j end{array}right)left(begin{array}{c} k-j \ j end{array}right) $

I gave mysel the following

Problem: For $k$ even and $ngeq k$, can one find a closed formula for the sum
$$
N:=sum_{j=0}^{k/2}left(begin{array}{c}
n \
k-j
end{array}right)left(begin{array}{c}
k-j \
j
end{array}right)?
$$

At first, I thought that some sort of Vandermonde’s identity could solve this. Now I believe this is far from trivial, if possible at all. I want to make sure I am not mistaken.

metric spaces – Continuous function takes discrete value on disjoint closed sets

Let $(X,d)$ be a metric space. $A,B$ be disjoint closed subsets of $X$. Then there must exists a continuous function $f$ on $X$, with $f(A)=0$, $f(B)=1$.

My idea is to take combination of distance function to $A, i.e$ $1-d(x,A)$. Then the function is continuous and take value 0 on $A$. But I got stuck how to take care of the values in $B$.
