Any 5 algebraic formulas

Ostrovityanka [42]

Answer:

a2 – b2 = (a – b)(a + b)

(a + b)2 = a2 + 2ab + b2

a2 + b2 = (a + b)2 – 2ab

(a – b)2 = a2 – 2ab + b2

(a + b + c)2 = a2 + b2 + c2 + 2ab + 2bc + 2ca

(a – b – c)2 = a2 + b2 + c2 – 2ab + 2bc – 2ca

(a + b)3 = a3 + 3a2b + 3ab2 + b3 ; (a + b)3 = a3 + b3 + 3ab(a + b)

(a – b)3 = a3 – 3a2b + 3ab2 – b3 = a3 – b3 – 3ab(a – b)

a3 – b3 = (a – b)(a2 + ab + b2)

a3 + b3 = (a + b)(a2 – ab + b2)

(a + b)4 = a4 + 4a3b + 6a2b2 + 4ab3 + b4

(a – b)4 = a4 – 4a3b + 6a2b2 – 4ab3 + b4

a4 – b4 = (a – b)(a + b)(a2 + b2)

a5 – b5 = (a – b)(a4 + a3b + a2b2 + ab3 + b4

In how many ways can 5 different novels, 4 different mathematics books, and 1 biology book be arranged on a bookshelf if: (a) Th

Zinaida [17]

Answer:

(a) 3628800 ways

(b) 17280 ways

Step-by-step explanation:

Given

$Novels = 5$

$Maths = 4$

$Biology = 1$

$Total = 10$

Solving (a): Arrangement with no restriction.

We simply count each book with no restriction. i.e. 10 books

So, the number of arrangement is:

$Arrangement =10!$

$Arrangement =10*9*8*7*6*5*4*3*2*1$

$Arrangement =3628800$

Solving (b): Maths book together and Novels together

First, arrange the 4 maths books as:

$Maths = 4!$

Next, arrange the 5 novels as:

$Novels = 5!$

Lastly, take the 4 maths book as [1], the 5 novels as [1] and the remaining [1] biology book.

So, we have: 3 books

Arrange 3 books, we have:

$Books = 3!$

Total arrangement is:

$Total = 4! * 5! * 3!$

$Total = 4*3*2*1 * 5*4*3*2*1 * 3*2*1$

$Total = 17280$

Solving (c): Maths book together

First, arrange the 4 maths books as:

$Maths = 4!$

Next, take the 4 maths book as [1], then the remaining 6 books (i.e. 5 novels and 1 biology)

So, we have: 7 books

Arrange 7 books, we have:

$Books = 7!$

Total arrangement is:

$Total = 4! * 7!$

$Total = 4*3*2*1 * 7*6*5*4*3*2*1$

$Total = 120960$

Lerok [7]

If we sum up or total the given percentages, it will give us 100%. The number of cars being sedan which the company should manufacture must be equal to the 15,000 cars per month times the percentage of sedans.
sedan cars = (15,000 cars/month) x (0.19) = 2850 cars/ month
Thus, out of the 15,000 cars that the company is planning to manufacture, 2,850 of which should be sedan.
