(9x 10^-3)^2=\frac{81x^{2}}{1000000}, so d 8.1x10^-6

Evaluate 1/2a^-4b^2 for a =-2 and b=4

\frac{1}{2} (-2)^{-4} *4^{2}\\\\\frac{1}{2} *\frac{1}{(-2)^{4}} *4^{2}\\\\\frac{1}{2} *\frac{1}{2^{4}}*4^{2}\\\\\frac{1}{2} *\frac{1}{16}*4^{2}\\\\\frac{1}{2} *\frac{1}{16}*16=\frac{1}{2}

A number raised to a negative exponent is sometimes negative.

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

The polynomial −2x2 + 700x represents the budget surplus of the town of Alphaville. Betaville's surplus is represented by x2 − 4
matrenka [14]

Answer:

- x²+ 300x + 50,000

Step-by-step explanation:

The polynomial −2x² + 700x represents the budget surplus of the town of Alphaville.

Again, Betaville's surplus is represented by x² − 400x + 50,000.

{where x is the tax revenue in thousands from both towns}

Now, the expression that represents the total surplus of both towns together will be

= (−2x² + 700x) + (x² − 400x + 50,000)

=  - x²+ 300x + 50,000

where x is the tax revenue in thousands from both towns. (Answer)
