First lets work out the length of the top side which joins the points (-1,7) and (-5,5):-

this = sqrt ( (7-5)^2 + (-1 - (-5)^2 )

= sqrt (4 + 16)

= sqrt 20

Now find length of the longer side which is distance between the points (-1,7) and (4, -3)

this is sqrt ( (-1 - 4)^2 + (7 - -3)^2)

= sqrt 125

Area of the rectangle = sqrt 20 * sqrt 125

= sqrt 2500

= 50 units^2 Answer

The parallelogram below is being covered with carpet. The carpet is priced at $2.80 per square meter. How much will it cost to c

Sloan [31]

Answer:

$79.38

Step-by-step explanation:

Find the diagram of the question attached

Area of the parallelogram = Base * Height

Given

Base = 8.1m

Height = 3.5m

Area of the parallelogram = 8.1 * 3.5

Area of the parallelogram = 28.35m²

If the carpet is priced at $2.80 per square meter, then;

1m² = $2.80

28.35m² = x

x = 28.35 * 2.80

x = $79.38

Hence the cost of the carpet is $79.38

The area of cross section of a prism is 45cm² and its height is,10cm. Find its volume

mrs_skeptik [129]

Answer:

The Volume of triangular prism

V = 450 cm³

Step-by-step explanation:

Explanation:-

Given The area of cross section of a prism A = 45cm²

and height (h) = 10 cm

The Volume of triangular prism

V = ( Base area X Height )

= 45 X 10

= 450 cm³

The Volume of triangular prism

V = 450 cm³

Find the domain for each expression. (1/x)+5 1/x X+5/x+5 X^2/x 7/(x-2)

wel

Using it's concept, it is found that the domain for the expressions is, respectively, given by:

$x \neq 0, x \neq 0, (-\infty, \infty), (-\infty, \infty), x \neq 2$

<h3>What is the domain of a function?</h3>

It is the set that contains all possible input values.

In a fraction, the denominator cannot be zero, hence:

The domain of the first two expressions is of $x \neq 0$ .

The domain of the last expression is of $x \neq 2$ .

The third expression can be simplified, as:

(x + 5)/(x + 5) = 1.

The same is true for the fourth, as:

x²/x = 1.

Neither has any restriction, hence their domain is all real numbers, represented by $(-\infty, \infty)$ .
