yeah, i just did the derivative first and added that last x at the end, same result

ah ok you're adding the final x directly to the polynomial, that's fine then, yes

no, you need to derivate the f(x) function twice because the last line asks for f"(x). you do that by taking down the exponent in front of each power of the polynomial and decreasing the power by one each time you derivate.

So for the 13x³: derived once it becomes 3 times 13 x², which equals 39x². Derived a second time, it is 2 times 39x, so 78x.

The 11x² becomes 2 times 11x, and then just 22 (times x power zero). the rest disappears after two derivatives.

The x is given when finding the correct pattern that matches the missing symbol in the first part of the problem, being the dot, so 52. I explained how you find this in a comment somewhere up here :)

I agree with your solution! GG

• f'(x) = 3(13)x²+2(11)x+10
• f"(x) = 6(13)x+22 = 72x + 22
• f"(52) = 4056 + 22 = 4 078

4078 + 52 = 4 130

no the correct pattern is 52, using the following method:

• for each column, superpose the outer diagonal lines of the first and second pattern, lines that appear in both symbols are suppressed in the third (bottom) pattern, lines that only appear in one of the two first patterns are kept.
• for each column, superpose the clock hands of the first and second pattern, only keep the clock hands that appear in both symbols at the same position.

The third column has the same diagonal lines in the first and second pattern, so they disappear. Those two symbols have different clock hands so they also disappear. So the only remaining element in the pattern is the central dot (52).

i totally agree, it's still good problem solving skill

that's really impressive, parsing so much information from a 2 step problem displayed skewed on a garbled background

Yup same, i looked it up and it all came back. However, it's still a completely useless knowledge in my normal adult life, though i'm a software engineer

Great name!

curious how the sword handles non binary and trans people

haha there are a few of those too!

it's a word with many meanings

• bande (noun, f.): a stripe, a strip, a reel (cinema), a frequency band (FM, AM)
• bande (noun, f.): a band, a herd, a troop, a gang, a group of individuals
• bander (verb): to draw (a bow)
• bander (verb): to bandage up (a wound)
• bander (verb): to have a hard on

"bander" is the french verb to "have a hard on" so it's still on track in my books

translation of the title:

after promoting the vote for Alternative for Germany (nazi party, radical right), Musk presents a new jump

like a dipshit

"my idea would be a great idea!"

also, Québec would 100% go independent

of course!

• Annex 49 of the decree about the requirements to evacuate used water in waterways (Abwasserverordnung - AbwV)
• Requirements described by DIN EN 858 parts 1 and 2, DIN 1999-100, DIN 1999-101, DIN 1986-3, DIN 1986-30, DIN EN 1610 and codes of practice DWA-M 167 parts 1 and 2 and ATV-M 143 part 6

it's mainly to avoid polluting the groundwater, environmental laws are strict and people tend to stick to the rules (and will call the police on you if you don't)

Meanwhile in Germany, you can't clean your car in your own driveway because it could pollute the soil, with a fine up to €50k

i started doing that and using my first name, much easier :)
