7 0

Answer:  see below

<u>Step-by-step explanation:</u>

7) Algebraic Inequality: x ≠ 3  

   -->    -∞ < x < 3 and 3 < x < ∞

   Graph:  ←-----------o-----------→

                               3

  Interval Notation: (-∞,3) ∪ (3, ∞)

8) This is a duplicate question of #7

9) Algebraic Inequality: x ≠ 2 and x ≠ 7

    -->  -∞ < x < 2 and 2 < x < 7 and 7 < x < ∞

   Graph:  ←-------o-------o-------→

                           2        7

  Interval Notation: (-∞, 2) ∪ (2, 7) ∪ (7, ∞)

10) Algebraic Inequality: x ≠ -4 and x ≠ 0

    -->  -∞ < x < -4 and -4 < x < 0 and 0 < x < ∞

   Graph:  ←-------o-------o-------→

                          -4        0

  Interval Notation: (-∞, -4) ∪ (-4, 0) ∪ (0, ∞)

A fish tank is a cube. Its side length is 4 1/2 feet. The volume of water needed to completely fill the fish tank is ___ cubic f
GalinKa [24]

The equation for the volume of a cube is V=s^3, where V is volume and s is side length.  Plug in and solve:

V=4.5^3

V=4.5*4.5*4.5

V=91.125ft^3

Hope this helps!!

((-2^2)(-1^-3))•((-2^-3)(-1^5))^-2
Vitek1552 [10]

Answer:

  256

Step-by-step explanation:

A calculator works well for this.

_____

None of the minus signs are subject to the exponents (because they are not in parentheses, as (-1)^5, for example. Since there are an even number of them in the product, their product is +1 and they can be ignored.

1 to any power is still 1, so the factors (1^n) can be ignored.

After you ignore all of the things that can be ignored, your problem simplifies to ...

  (2^2)(2^-3)^-2

The rules of exponents applicable to this are ...

  (a^b)^c = a^(b·c)

  (a^b)(a^c) = a^(b+c)

Then your product simplifies to ...

  (2^2)(2^((-3)(-2)) = (2^2)(2^6)

  = 2^(2+6)

  = 2^8 = 256
