Answer:

Rate of change = 6 miles per hour

Step-by-step explanation:

Rate of change of the line is represented by the slope of the line.

Formula to get the rate of change is,

m = \frac{\triangle y}{\triangle x}

From the graph attached,

Given straight line is passing through two points (2, 12) and (4, 24).

Rate of change = \frac{y_2-y_2}{x_2-x_1}

                          = \frac{24-12}{4-2}

                          = 6

Rate of change of the line = 6 miles per hour

Therefore, rate of change of the graph will define the speed of Arlene.

A = 11m, b = 8m and C = 2m for the triangle shown below.
Aleksandr-060686 [28]

Answer:

x = \sqrt{53}

Step-by-step explanation:

Using Pythagoras' identity on the upper right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Let the third side be d, then

d² + b² = a² , that is

d² + 8² = 11²

d² + 64 = 121 ( subtract 64 from both sides )

d² = 57

Using Pythagoras' identity on the lower right triangle, then

x² + c² = d²

x² + 2² = 57

x² + 4 = 57 ( subtract 4 from both sides )

x² = 53 ( take the square root of both sides )

x = \sqrt{53}
