M is directly proportional to r2 <br> When r=2, m=14<br> Work out the value of m when r=12
Genrish500 [490]

we have M is durectly porpotional to r^2

so M=(k)r^2

and when r=2, m=14

so 14=(k)(2)^2

k=14/4 =7/2

so when r=12

m= (7/2)(12)^2 =(7/2)(144) = 504

Which expression below gives the average rate of change of the function g(x) = -x2 - 4x on the interval 6 ≤ x ≤ 8 ?
Paha777 [63]

Answer: -18

<u>Explanation:</u>

Average rate of change is slope: \frac{y_{2}-y_{1}}{x_{2}-x_{1}}.  Need to find the y-coordinates:

g(x) = -x² - 4x

g(6) = -(6)² - 4(6)

      = -36 - 24

      = -60

⇒ (6, -60)

g(8) = -(8)² - 4(8)

      = -64 - 32

      = -96

⇒ (8, -96)

m = \frac{-96 - (-60)}{8 - 6}

   = \frac{-36}{2}

   = -18
