whats 1+1?
please do answer!
Answers
Answer:
I thought it was 3, no wait its 2
Step-by-step explanation:
You are thinking of the Principia Mathematica, written by Alfred North Whitehead and Bertrand Russell. Here is a relevant excerpt:
Picture Below
As you can see, it ends with "From this proposition it will follow, when arithmetical addition has been defined, that 1+1=2." The theorem above, ∗54⋅43, is already a couple of hundred pages into the book (Wikipedia says 370 or so); the later theorem alluded to, that 1+1=2, appears in section ∗102, considerably farther on.
I wrote a blog article a few years ago that discusses this in some detail. You may want to skip the stuff at the beginning about the historical context of Principia Mathematica. But the main point of the article is to explain the theorem above.
The article explains the idiosyncratic and mostly obsolete notation that Principia Mathematica uses, and how the proof works. The theorem here is essentially that if α and β are disjoint sets with exactly one element each, then their union has exactly two elements. This is established based on very slightly simpler theorems, for example that if α is the set that contains x and nothing else, and β is the set that contains y and nothing else, then α∪β contains two elements if and only if x≠y.
The main reason that it takes so long to get to 1+1=2 is that Principia Mathematica starts from almost nothing, and works its way up in very tiny, incremental steps. The work of G. Peano shows that it's not hard to produce a useful set of axioms that can prove 1+1=2 much more easily than Whitehead and Russell do.

Miss Landry is getting married soon. She would like to hire a professional who will come to her house and do hair and makeup for the bridal party on her wedding day. She has narrowed it down to two possible choices. A woman from Springdale Salon charges an initial fee of $40 and then an additional $15 per hour. Alternatively, a team from Beauty by Dan offers a free consultation and then charges a higher hourly rate of $35. If it takes a certain amount of time to finish everyone's hair and makeup, Miss Landry will end up paying the same amount either way. How much would Miss Landry end up paying?

The three side lengths best describe the triangle in the diagram are A. 5 cm, 12 cm, and 13 cm
What is a triangle?A polygon with three sides and angles is called a triangle.
Given is a figure, with the rulers attached to each side, we need to see what are the measurements of the sides of the triangle,
The first side is showing a measure of 13
The second side is showing a measure of 12
And, the third one is showing a measure of 5
This is a right triangle because the measurements are Pythagorean triplets.
Hence, the three side lengths best describe the triangle in the diagram are A. 5 cm, 12 cm, and 13 cm

f(-2) = 0
f(1) = 12
f(2) = 5
Step-by-step explanation:
f(-2) will lie in the function [tex] f(x) =x^2 - 4[/tex]
[tex]\therefore f( - 2) = {( - 2)}^{2} - 4 = 4 - 4 = 0 [/tex]
f(1) will lie in the function [tex] f(x) =2x^2 +10[/tex]
[tex]\therefore f(1) = 2 {(1)}^{2} + 10 = 2 + 10 = 12 [/tex]
f(2) will lie in the function [tex] f(x) =5[/tex]
