Find the slope of line passing through the two points, (7, 1) and (-2, 1).
Mamont248 [21]

Answer: m = 0

Step-by-step explanation:

Slope (m) = y2 - y1/,x2 - x1 : meaning increase in y divided by increase in x . it can also be written as ∆y/∆x

y1= 1, y2 = 1, x1 = 7, x2 = -2

Substitute for those values in the equation above

m = 1 -1/-2 - 7

= 0/-9

Therefore,

m = 0

The slope of the line passing through those coordinates = 0

Rad 18x^5y + Rad 32xy^3 - Rad 128xy
True [87]
Sqrt(18x^5y) + sqrt(32xy^3) - sqrt(128xy)
You may separate the roots to produce solvable square roots!

sqrt(9x^4)*sqrt(2xy) + sqrt(16y^2)*sqrt(2xy) - sqrt(64)*sqrt(2xy)

Simplifying makes it ...
(3x^2 + 4y - 8)*sqrt(2xy)
This should be the closest you can get to a simplified equation.

Tatami mats are used as a floor covering in japan. One possible layout uses four identical rectangular mats and one square mat,
Maksim231197 [3]

a) Given

Total area = 81 feet squared.

 Let the area of the square mat = x feet.

From question, area of the rectangular mat is twice that of square mat.

 So, the area of the rectangular mat = 2 x feet.

Now,

Total area = 81 feet squared

Then,

      4(2 x) + x = 81\\ \\ 9 x = 81\\ \\  x = \frac{81}{9}\\ \\ x = 9\\

Hence  the area of the one rectangular mat = 2*9 = 18 feet squared

b) Let the width of the rectangular mat = y feet.

  Then length of the mat = 2 y feet.

   Area of the rectangle = 2 y* y = 2 y^{2}

   and area of rectangle = 18 feet squared.

   So,

 2 y^{2} = 18\\ y^{2} = 9\\ y= \pm3\\

Width can not be negative.

Hence, the width of the rectangular mat = 3 feet

and  length of the rectangular mat = 3*2 = 6 feet

What is the volume of this equation?
Pachacha [2.7K]

Answer:

Volume ≈ 33.33 cubic feet

Step-by-step explanation:

The question is:

<em>Find the volume of a right square pyramid with base square edges measuring 5 feet each and a height of the pyramid be 4 feet.</em>

<em />

So, the base is a square with side length 5 feet.

And the height of the pyramid is 4 feet.

The volume of a pyramid is given by the formula:

V=\frac{a^2 h}{3}

Where

a is the square base side length (given as 5)

h is the height of the pyramid (given as 4)

Now we substitute and find the value:

V=\frac{a^2 h}{3}\\V=\frac{(5)^2 (4)}{3}\\V=33.33

The volume is around 33.33 cubic feet
