Which expression below gives the average rate of change of the function g(x)= -x^2 -4x on the interval 6 ≤ x ≤ 8?
DiKsa [7]
The average rate of change of a function, g(x), over an interval [a, b] is given by 

Average\ rate\ of\ change= \frac{g(b)-g(a)}{b-a}

Thus, the average rate of change of g(x)=-x^2-4x over the interval 6\leq x\leq8 is given by:

Average\ rate\ of\ change= \frac{[-(8)^2-4(8)]-[-(6)^2-4(6)]}{8-6} \\  \\ = \frac{(-64-32)-(-36-24)}{2} = \frac{-96-(-60)}{2} = \frac{-96+60}{2} = \frac{-36}{2}  \\  \\ -18

Given cos theta=4sqrt2/7 find sin theta
m_a_m_a [10]

Answer:

  • sin \theta=\sqrt{17}/7

Step-by-step explanation:

<h3>Given</h3>

  • cos \theta=4\sqrt{2}/7

<h3>Find</h3>

  • sin \theta

<h3>Solution</h3>

Use identity:

  • sin^2x+cos^2x=1

Substitute and find:

  • cos^2 \theta=(4\sqrt{2}/7)^2
  • cos^2 \theta=16*2/49=32/49

  • sin \theta=\sqrt{1-cos^2 \theta}  = \sqrt{1-32/49} =\sqrt{17/49} =\sqrt{17}/7
