How would you determine which x-values to use when creating a table of values to graph a parabola?

To determine which values of x we would use for creating a graph of a parabola, we need to know where the line of symmetry, or the axis of symmetry is. For that we can use the equation:

y=(x-h)+k, where we know h and k.

From this equation we can see that the line of symmetry is passing trough x=h.

And now we can determine which values do we need to add to h and to subtract from h to get values of x to create the table of values to plot a parabola.

Find the area of quadrilateral KLMN​
WITCHER [35]

Step-by-step explanation:

I just answered this ...

the first thing we notice : the quadrilateral has 2 pairs of equally long sides with 2 angles being openly 90°.

so, we are dealing with a rectangle here.

we know that one pair of the sides (NK = LM) are 24 cm long.

and we know that KL:LM = 3:4.

that means that the pair KL = MN are the shorter sides of the rectangle. and their length is according to the ratio 3/4 of NK=LM.

3/4 × 24 = 18 cm

the area of that rectangle is therefore

18 × 24 = 432 cm²

A pizza shop wants to determine how often it delivers to three different areas of a city. The table shows the areas from a rando
aleksandrvk [35]

Answer:

55 Southern deliveries.

Step-by-step explanation:

Let's make a ratio

Northern : Central : Southern : Total

    14        :     44     :       22      :   80

     7         :     22     :       11        :   40

    35        :     110     :      55      :  200

We can see from our ratio, that there are 55 Southern deliveries when 200 deliveries are delivered.

Which dot plot has the least number of sites
shtirl [24]

The dot plot with the least number of sites has the least frequency

The dot plot has the least number of sites is the Shield Darter

<h3>How to determine the dot plot?</h3>

To determine the dot plot with the least number of sites, we simply calculate the total frequency of each dot plot

So, we have:

Shield Darter = 3 + 1 + 4 + 2 + 3 + 1 + 1

Shield Darter = 15

Calico Crayfish = 1 + 1 + 3 + 4 + 1 + 2 + 4 + 2

Calico Crayfish = 18

Zebra Mussel = 1 + 3 + 2 + 5 + 1 + 1 + 2 + 3 + 2

Zebra Mussel = 20

Blue back Herring = 3 + 3 + 2 + 1 + 3 + 1 + 4

Blue back Herring = 17

From the computation above, the least frequency is

Shield Darter = 15

Hence, the dot plot has the least number of sites is the Shield Darter
