F(x)=x^2+9x-16<br><br><br> What is vertex <br><br> Axis of semetry
UNO [17]

Answer:

axis of symmetry is x=\frac{-9}{2}.

The ordered pair of the vertex is (\frac{-9}{2},\frac{-145}{4}).

Step-by-step explanation:

Your function is a quadratic.

Compare x^2+9x-16 to ax^2+bx+c.

You should see that a=1,b=9,c=-16.

The x-coordinate of the vertex or the axis of symmetry since the axis symmetry goes through the vertex can be found by computing \frac{-b}{2a}.

So here we go!

The axis of symmetry is x=\frac{-9}{2(1)}=\frac{-9}{2}.

When you write your axis of symmetry be sure to write it as an equation.

That is the axis of symmetry is x=\frac{-9}{2}.

Now that was also the x-coordinate of your vertex.  To find the corresponding y-coordinate of the vertex, plug your value for x into

y=x^2+9x-16.

y=(\frac{-9}{2})^2+9(\frac{-9}{2})-16

Put into calculator:

y=\frac{-145}{4} when x=\frac{-9}{2}

The ordered pair of the vertex is (\frac{-9}{2},\frac{-145}{4}).

How many acres are there in the W 1/2 of the S 1/2 of the SW 1/2 of a section of land? 50 acres? 15 acres? 80 acres? 160 acres?
tamaranim1 [39]

1/2 of 1/2 of 1/2 = 1/8.

There are 640 acres in a section, so 1/8 section = 80 acres.

_____

In surveying terms, "SW 1/2 of a section" is not a realistic specification of a piece of property.
