Answer:

  (a^8)/(b^9)

Step-by-step explanation:

Two rules of exponents come into play.

  (a^b)/(a^c) = a^(b-c)

  a^-b = 1/a^b

__

Applying the first rule, we have ...

  (a^3)/(a^-5) × (b^-2)/(b^7) = a^(3 -(-5)) × b^(-2 -7) = a^8 × b^-9

Applying the second rule gives the simplified form ...

  = (a^8)/(b^9)

The Blackburn family has a square fold where they keep their cattle.The area of the field is 40,000ft square, and Mr. Blackburn
grandymaker [24]

Answer: Length of fence along the diagonal is 28.3 feet.

Step-by-step explanation:

Since we have given that

The Blackburn family has a square field ,

Area of square = 40000 ft square

As we know the formula,

Area of square = Side x Side

40000 = slide{2}

\sqrt 40000\\

20 ft = Side

But Blackburn wants to put a fence diagonally through the field ,

As we know the formula for "Diagonal of side" i.e.

Diagonal of square \sqrt2Slide

Diagonal of square 20\sqrt2

So,

Length of fence along the diagonal = 20 x 1.41 = 28.3

Hence, length of fence along the diagonal is 28.3 feet.

Hope this helps!

Debora [2.8K]

Answer:

the value of the z is -3.5

Step-by-step explanation:

According to the question, the following information is given

-2z - 7

Based on the above information

We assume that we have to determine the z value

so

-2z - 7 = 0

-2z = 7

z = 7 ÷ -2

= -3.5

Hence, the value of the z is -3.5

The same is to be considered and relevant too
