Please Help ASAP Evaluate (64^1/2)^-2/3
Naya [18.7K]

Answer:

Option A.

Step-by-step explanation:

The given expression is,

[(64)^{-\frac{1}{2}}]^{-\frac{2}{3}}

By solving the given expression,

(64)^{-\frac{1}{2}}=\frac{1}{(64)^{\frac{1}{2}}} [Since a^{-1}=\frac{1}{a}]

           =\frac{1}{\sqrt{64}}

           =\frac{1}{8}

Now the expression will be,

[(64)^{-\frac{1}{2}}]^{-\frac{2}{3}}=(\frac{1}{8})^{-\frac{2}{3}}

                 =8^{\frac{2}{3}}

                 ={(\sqrt[3]{8})^2}

                 = 2²

                 = 4

Therefore, value of the given expression will be 4.

Option (A) will be the answer.

Consider f(x)=2|x|
shusha [124]

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the average rate of change of f(x) in the closed

interval [a, b] is

\frac{f\left(b\right)-f\left(a\right)}{b-a}

Given the interval [a, b] = [0, 4]

as

f(x)=2|x|

f(b)=f(2)=2\cdot \:4       ∵  \mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0

      = 8

   

f(x)=2|x|

f(a)=f(0)=2\cdot \:0       ∵  \mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0

       = 0

so the average rate of change  :

\frac{f\left(b\right)-f\left(a\right)}{b-a}=\frac{8-0}{4-0}

              =\frac{8}{4}

               = 2

We know that a rate of change basically indicates how an output quantity changes relative to the change in the input quantity. Here, it is clear the value of y increase with the increase of input.
