Answer:

Option (A)

Step-by-step explanation:

The given expression is,

(5^{-2}\times 4^{-4})^{-2}

Since x^{-1}=\frac{1}{x} and \frac{1}{x^{-1}}=x

5^{2}=\frac{1}{5^{-2}}

4^{2}=\frac{1}{4^{-2}}

Therefore, (5^{-2}\times 4^{-4})^{-2}=\frac{1}{(5^{-2}\times 4^{-4})^{2}}

                                         =\frac{1}{(5^{-2})^2\times (4^{-4})^2}

                                         =\frac{1}{5^{-4}\times 4^{-8}}

                                         =\frac{1}{5^{-4}}\times \frac{1}{4^{-8}}

                                         =5^{4}\times 4^{8}                            

Option (A) will be the answer.

a_sh-v [17]

Answer:

 x = $ 16,000  , y = $13,000  z= $11,000

Step-by-step explanation:

given,

Investment amount $40,000

three investments yielding = $3,500

three investments are 7%, 9%, and 11%

second and third are $3,000 and $5,000 less than the first  

        0.07 x + 0.09 y + 0.11 z = $ 3,500  

        x + (x - 3000 ) + (x - 5000) = $ 40,000

           3x = $48,000

             x = $ 16,000

     y = 16000 - 3000 = $ 13,000

     z = 16000 - 5000 = $ 11,000

the investment by each

 x = $ 16,000  , y = $13,000  z= $11,000

 A road has a 16.7% grade.<br>Why might we want to warn drivers of a grade like this?
never [62]
The higher the percentage, the steeper the grade and the steeper the hill. This warning is issued so drivers are more careful (otherwise they would probably get into more accidents).
