Answer:
Step-by-step explanation:
To solve this problem we are going to set Python as the language.
books = ["a", "b", "c", ... , "z"]
selection = list(3) #here we set a list of dimension 3 as 3 are supposed to be selected
for book in books: #here we parse into the books list
If book in selection: continue #in order to obtain different books, if the book #already in selection list, then we jump
selection.append(random.choice(books)) #if not, we add the book to #selection
print(selection)
Answer: A sequence of numbers that has an ending rather than no ending.
There are infinite sequences and finite sequences in mathematics.
Hello,
Here is the graph of y=|4x+12| which is null for x=-3.
There is a theorem that says that this angle (formed by thre points on the circumference) is half such arc called EF.
We can deduct it as well.
1) Call O the center of the circle. The central angle (EOF) = arc EF = 151°
2) Draw a chord from F to D and other chord from D to E.
You have constructed two triangles, FOD and DOE.
3) Triangle FOD has two sides equals (because both are the radius of the circcle). Then, this is an isosceles triangle and it has two angles of the same measure. Call this measure a.
4) Triangle DOE is also isosceles, for the same reason explained in the poiint 3. Call the measure of its equal angles b.
5) The sum of the angles of the two triangles is 180° + 180 ° = 360°.
This is a + a + b + b + (360 - central angle) = 360°
=> 2a + 2b = central angle
=> 2(a+b) = cantral angle
=> (a+b) = central angle / 2 = 151° / 2 =71.5°
(a+b) is the angle that you are looking for.
Then the answer is 71.5°
Area = Length x Width
756 = 108 x Width
Width = 756/108
Width = 7
So the roof is 7 inches wide
