Enter the difference between the rates of change for these two functions.

Alchen [17]

Answer:

Step-by-step explanation:

Graph :

Choose any two points. (0 , 2) and (-1 , -2)

Rate of change = Change in y ÷ Change in x

$= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\= \frac{-2 - 2}{-1 - 0}\\\\= \frac{-4}{-1}\\\\= 4$

Table:

Rate of change = $\frac{-2-[-6]}{2-0}$

$= \frac{-2+6}{2}\\\\= \frac{4}{2}\\\\= 2$

hammer [34]

Answer:

51m

Step-by-step explanation:

-Paul is 6ft, and has a 10ft shadow. The pole has a 85ft shadow:

-Using ratios:

$\frac{Height\ of \ object}{Height\ of \ shadow}$

Let h be the height of the flagpole:

$=>\frac{6}{10}=\frac{h}{85}\\\\h=\frac{6\times 85}{10}\\\\h=51$

Hence, the height of the pole is 51m
