Let A={1'3'5'6}<br> B={0'7}<br> check whether A and B are disjoint sets
Setler79 [48]

Given:

The sets are A=\{1,3,5,6\} and B=\{0,7\}.

To find:

Whether A and B are disjoint sets or not.

Solution:

Two sets are called disjoint sets if there are no common elements between them.

We have,

A=\{1,3,5,6\}

B=\{0,7\}

Clearly, there is not common elements between the set A and set B.

Therefore, the sets A and B are disjoint sets.

How do you differentiate y = 3x3 - 2x-4
riadik2000 [5.3K]

Answer:

y' = 9x^2 + 8x^-5

Step-by-step explanation:

General Principle

y' = ax^b

y' = a*b * x^(b-1)

Solution

3x^3 = 3*3x^(3-1)

3x^3 = 9x^2

-2x^-4  = -2*-4 x ^(-4 - 1)

-2x^-4 = 8 x ^-5

Answer

y' = 9x^2 + 8x^-5

Can anyone figure this out for me please? It would be greatly appreciated.
Ira Lisetskai [31]
Check the picture below.

now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.

\bf 53-4\frac{1}{2}-4\frac{1}{2}\implies 53-9\implies \boxed{42}&#10;\\\\\\&#10;26-4\frac{1}{2}-4\frac{1}{2}\implies 26-9\implies \boxed{17}&#10;\\\\\\&#10;\textit{so the area of the rectangle in the middle is}\implies 42\cdot 17\implies 714&#10;\\\\\\&#10;\textit{and the area of the whole pool is}\implies 53\cdot 26\implies 1378

\bf \stackrel{\textit{area of the whole pool}}{1378}~~-~~\stackrel{\textit{area of the middle rectangle}}{714}\implies \stackrel{\textit{area of the tiles}}{664}\\\\&#10;-------------------------------\\\\&#10;\textit{we know that is }\$5\frac{1}{2}\textit{ for a foot of tile, then}\stackrel{\textit{price of the tiles}}{664\cdot 5\frac{1}{2}}\implies 3652

If f(x)=(2x^2)-1, find:<br> -f(3x-1)+2
Sergeeva-Olga [200]

Answer:

-f(3x - 1) + 2 = -18x² + 12x + 1

Step-by-step explanation:

Step 1: Find f(3x - 1)

f(3x - 1) = 2(3x - 1)² - 1

f(3x - 1) = 2(9x² - 6x + 1) - 1

f(3x - 1) = 18x² - 12x + 2 - 1

f(3x - 1) = 18x² - 12x + 1

Step 2: Plug in f(3x - 1)

-(18x² - 12x + 1) + 2

Step 3: Evaluate

-18x² + 12x - 1 + 2

-f(3x - 1) + 2 = -18x² + 12x + 1
