Why is a number raised to the zero power ALWAYS one and never any other number?

Do you know how to simplify, let's say for example,    x⁵/x²  ?

When the bases are the same, you can just subtract the exponent in
the denominator from the exponent in the numerator.  So  x⁵/x² = x³ .

Now look at  x⁷/x⁷ .  From that same handy tip, x⁷/x⁷ = x⁰ .

BUT ... any fraction with the same number on top and bottom
is equal to ' 1 '.  So  x⁰ = 1 , no matter what 'x' happens to be.

Does that do anything for you ?

What is the solution of the system? Use substitution.<br><br> y = 6x + 2<br> 3y - 18x = 12
kicyunya [14]
3(6x+2)-18x=12 (y=6x+2, so you plug in 6x+2 into the y in 3y-18x=12)
18x+6-18x=12    (Then you distribute the 3 to the 6x and to the 2)
6=12                    (Combine like terms 18x-18x)

There is no solution. Hope this helps and makes sense.

6. A prism has bases that are equilateral triangles with sides lengths of 10 inches and a length of 30 inches.
vova2212 [387]

Answer:

The volume of the prism is 1,299\ in^{3}

Step-by-step explanation:

we know that

The volume of the prism is equal to

V=BL

where

B is the area of the triangular base

L is the length of the prism

we have

L=30\ in

<em>Find the area of the base B</em>

The area of a equilateral triangle is equal to

B=\frac{1}{2}(10)^{2} sin(60\°)

B=25\sqrt{3}\ in^{2}

substitute

V=(25\sqrt{3})(30)=1,299\ in^{3}
