The greenhouse gas also denoted as GHG are gasses <span>produced through activities which release carbon dioxide, methane, nitrous oxide and ozone CFCs (chlorofluorocarbons) , absorb and emit radiation and hold heat in the atmosphere. The result is the greenhouse effect and the global warming.
</span><span>The three major greenhouse gases are found in Earth’s atmosphere:
</span><span>carbon dioxide, methane, and water vapor. Answer:(1)</span>

VMariaS [17]

Answer:

In explanation you see the answer but it I see it send it  different  so I just added a file so you can see clearly the way how this exercise works. Please, see the file attached

Explanation:

Let x = circumference of the circle

then

(53-x) = the perimeter of the square

and \frac{53-\times}{4} = the side of the square

and

\left(\frac{53-\times}{4}\right)^2 = the area of the square

:

Find the area of the circle using the circumference

find the radius (r)

2*pi*r = x

r = \frac{\times}{2*\mathbit{\pi}}

r = \frac{\times}{6.28}

Find the area of the circle

\mathbit{A}=\pi r^2

Replace r with \frac{\times}{6.28}

A = π * \left(\frac{\times}{6.28}\right)^2=  * \left(\frac{\times^2}{39.48}\right)      

cancel pi into 39.48

A =  \left(\frac{\times^2}{12.566}\right)

Total area of circle and square

A =  \left(\frac{\times^2}{12.566}\right)+\left(\frac{53-\times}{4}\right)^2  = \left(\frac{\times^2}{12.566}\right)  + \left(\frac{{2809-106\times+\times}^2}{16}\right)

:

convert these fractions to decimal coefficients

A(x) = .0796x^2 + .0625x^2 - 6.625x + 175.5625

A(x) = .1421x^2 - 6.625x + 175.5625

:

Find the axis of symmetry of this quadratic equation (min area)

x =   \frac{-\left(-6.625\right)}{2*.1421}

x =   \frac{6.625}{.2842}

x = 23.31 cm is the circumference when they have min area

Find the distance between each pair of points<br> (-5.2, 7) and (3,- 4)
Nadusha1986 [10]

Answer:

13.72units

Explanation:

Given parameters:

   Coordinates of the two points  =  (-5.2, 7) and (3,- 4)

Unknown:

Distance between the two points = ?

Solution:

To find the distance between two points, we use the mathematical expression below;

   D = \sqrt{(x_{2}-x_{1}  )^{2} + (y_{2} - y_{1} )^{2}   }

 From the given coordinates;

        x₁  = -5.2      x₂  = 3

        y₁ = 7             y₂ = -4

Now; input the parameters and solve;

  D  = \sqrt{[3-(-5.2)]^{2} + (-4 -7)^{2}  } = \sqrt{67.24 + 121} = 13.72units

The distance between the two points is 13.72units
