I'm a bit confused with simplifying a squared fraction. Can you explain to me how I do it?
Margaret [11]

Answer:

\frac{\sqrt{6} }{3}

Step-by-step explanation:

\sqrt{\frac{2}{3} }

\frac{\sqrt{2} }{\sqrt{3} }

Multiply by \frac{\sqrt{3} }{\sqrt{3} } to simplify

\frac{\sqrt{2} }{\sqrt{3} }*\frac{\sqrt{3} }{\sqrt{3} }

\sqrt{2} *\sqrt{3} =\sqrt{6}

\sqrt{3} *\sqrt{3} =3

Therefore, the final answer would be:

\frac{\sqrt{6} }{3}

Is 16x^2-56x+49 a perfect square trinomial? How do you know ? If it is, factor the expression. Please show your work
daser333 [38]

Answer:

  • yes
  • (4x -7)^2

Step-by-step explanation:

If it is, the first and last terms are perfect squares, and the middle term is twice the product of the roots of those squares.

  16x^ = (4x)^2 . . . . a perfect square

  49 = 7^2 . . . . . . . a perfect square

  -2(4x)(7) = -56x . . . . . matches the middle term, so the factoring is ...

  16x^2 -56x +49 = (4x -7)^2

_____

The sign in the binomial factors is the same as the sign of the middle term of the trinomial.

We have been given a graph of function g(x) which is a transformation of the function f(x)=3^x

Now we have to find the equation of g(x)

Usually transformation involves shifting or stretching so we can use the graph to identify the transformation.


First you should check the graph of f(x)=3^x

You will notice that it is always above x-axis (equation is x=0). Because x-axis acts as horizontal asymptote.

Now the given graph has asymptote at x=-2

which is just 2 unit down from the original asymptote x=0

so that means we need shift f(x), 2 unit down hence we get:

y=3^x


but that will disturb the y-intercept (0,1)

if we multiply 3^x by 3 again then the y-intercept will remain (0,1)

Hence final equation for g(x) will be:

g(x)=3(3^x)-2
