use the graph below to answer the following question: if slope is calculated using the equation, "m = (y2-y1) / (x2-x1)," what is the slope of the secant line? be sure to include all math work and units in your final answer.

8 cm/s

Explanation:

When the time is 0 s (x₁ = 0 s), the position of the rolling ball is 0 cm (y₁ = 0 cm).

When the time is 6 s (x₂ = 6 s), the position of the rolling ball is 45 cm (y₂ = 45 cm).

Using these 2 points, we can find the slope (m) of the secant line.

m = (y₂ - y₁)/(x₂ - x₁) = (45 cm - 0 cm)/(6 s - 0 s) = 8 cm/s (we round off to 1 significant figure)

they are known to reach a speed of 21 miles per hour

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
