sergey [27]

The length of side CD is equal to 11 units.

Given coordinates of rectangle are A(-7,-5), B(-7,6),C(-4,6) ,D(-4,-5)

We are require to find the length of side CD.

Rectangle is a two dimensional figure whose two opposite sides are equal to each other. Distance between two coordinates is the equal to length of a side.

We know that the distance means how far two points are located.

Coordinates of  A(-7,-5), B(-7,6),C(-4,6) ,D(-4,-5).

Distance=\sqrt{(x_{2} -x_{1} )^{2} +(y_{2} -y_{1} )^{2} } where (x_{1} ,y_{2} )(x_{2} ,y_{2} ) are the coordinates of two ends of a line.

CD=\sqrt{(-5-6)^{2} +(-4+4)^{2} }

=\sqrt{11^{2}+0^{2}  }

=\sqrt{121}

=11 units.

Hence the length of side CD is 11 units.

Answer:

3.3 x 10⁻⁴

Step-by-step explanation:

Given expression:

           \frac{2.64 x 10^{-3} }{8.0 x 10^{0} }

 To solve this problem;

    10°   = 1

So;

             \frac{2.64 x 10^{-3} }{8.0}

    =  \frac{2.64}{8}  x 10⁻³

    = 0.33 x 10⁻³

    = 3.3 x 10⁻¹  x 10⁻³

     = 3.3 x 10⁻⁴
