Answer:

C. \:  \:  7.07

Step-by-step explanation:

Coordinates of B are

(5,5)

Coordinates of C are

(4, - 2)

Distance between two points

\sqrt{({x_2 - x _1 {)}^{2} + (y_2 - y_1 {)}^{2} }}

Distance of BC

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

\sqrt{ { (- 1}^{2})  +  ({ - 7}^{2}) }

\sqrt{1 +49 }

\sqrt{50}

7.07

Answer:

D'G' = 52.5 units

Step-by-step explanation:

Since the dilatation is centred at the origin then multiply the original coordinates by the scale factor 3.5

D' = (1 × 3.5, 7 × 3.5 ) = (3.5, 24.5 )

G' = (- 8 × 3.5, - 5 × 3.5 ) = (- 28, - 17.5 )

Calculate D'G' using the distance formula

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

with (x₁, y₁ ) = D' (3.5, 24.5) and (x₂, y₂ ) = G' (- 28, - 17.5)

D'G' = \sqrt{(-28-3.5)^2+(-17.5-24.5)^2}

       = \sqrt{(-31.5)^2+42^2}

       = \sqrt{992.25+1764}

        = \sqrt{2756.25}

         = 52.5 units

The slope of the function is $400.

<h3 /><h3>Definition of slope of a function</h3>

The slope of a function is the rate of change of the dependent variable with respect to the independent variable. The equation that represents a function is: y = mx + b

Where:

  • y = dependent variable
  • m = independent variable
  • x = slope
  • b = constant

Looking at the total money raised, the amount of money increases by 400. This is the slope.
