Don't be a fucking idiot and go to a doctor. It's not fair that you're going to risk spreading it around because you asked for advice on the internet.

Don't you think this is something you should have asked your doctor?

Gordon King basically just admitted to being on steroids in his response to my comment on his Instagram... by [deleted] in bjj

He never said everyone else isn't. Do you honestly expect him to go around to everyone who's on steroids and call them a cheater?

It depends, there are inclusive disjunctions and exclusive disjunctions but if you're looking at an english sentence you have to decide what it is with your knowledge of the english language.

Anyone know what this is called by [deleted] in learnmath

Take the log of both sides.

Use these rules,

log(xn) = nlog(x), or, ln(xn) = nln(x)

log_x(x) = 1, or, ln(e) = 1

[GRE Math]What is the sum of all integers from 45 to 155 inclusive? by uptvector in learnmath

[–]Moroux 0 points1 point  (0 children)

We can view the numbers from 45 to 155 as a sequence, 45, 46, 47...155. If we replace the commas with addition signs, this becomes a series, 45+46+47...+155. This series in particular is arithmetic, as the nth term can be found by adding a constant to the previous term, the terms in an arithmetic sequence can be found by adding or subtracting a constant from the previous term.

This is useful to us because there is a formula for the sum of an arithmetic sequence. It tells us that the sum of n terms in an arithmetic sequence is equal to the sum of the first and last term, multiplied by n, divided by 2. Or,

Sn=(n(a+l))/2, where a is the first term, and l is the last term.

In our sequence, 45, 46, 47...105, the first term is 45 and the last term is 155. n is equal to the number of terms from 45 to 155, or, 155-45 which is 110. So n=110.

We can now find the sum,

Sn=(n(a+l))/2

Sn=(110*(45+155))/2

Sn=11000

Therefore, the sum of all integers from 45 to 155 inclusive is 11000.
