Given the table of values below, which of the following ordered pairs are
antiseptic1488 [7]

Answer:

(12,-2), (10,-1), (8,0), (6,1) and (4,2).

Step-by-step explanation:

If a function is defined as

f(x)=\{(x,y):x\in R,y\in R\}

then its inverse is defined as

f^{-1}(x)=\{(y,x):x\in R,y\in R\}

It means coordinates of ordered pairs are interchanged.

From the given table it is clear that the function passing through the points (-2,12), (-1,10), (0,8), (1,6) and (2,4).

Using the above definition, we can say that the inverse function passing through the points (12,-2), (10,-1), (8,0), (6,1) and (4,2).

Therefore, the required ordered pairs are (12,-2), (10,-1), (8,0), (6,1) and (4,2).

Answer:

3.14 or pi

Step-by-step explanation:

the area of a circle = pi * r^{2} where r is the radius of the circle

this is 1/4 of the circle, so it would be 1/4 (pi * r²)

it shows that the radius is 2, so you have

1/4 ( pi * 2²)

= 1/4 ( pi * 4 )

= 1/4 (3.14 * 4)

= 3.14 units²

Effectus [21]

Answer:

<h2><u><em>74 m</em></u></h2>

Step-by-step explanation:

<em>Jakub wants to build a new shed.</em>

<em>The area of the shed is 37 m².</em>

<em>The width of the shed is 5 m.</em>

<em>What is the length of the shed?</em>

to find the side, having the area, you need to use the inverse formula Area = W * L

so

L = A: W

L = 37 : 5 =<u><em> 7.4 m</em></u>
