Gosh I hope you didn't have to turn this in yet. I'll help you with 4 and 5.

If you want to find the unit rate, you're finding out how much money it is per ounce.
Divide your cost by the number of ounces.

So for example, 3.98 / 16.

After you get your answers, write them down. Whichever answer is the lower number is the better buy because each ounce costs less.

(-1,3) (3,0) (-1.-2) find perimiter

KATRIN_1 [288]

Answer:

$p$ ≈ $14.5$

Step-by-step explanation:

Find the distance between the three pairs first using the distance formula:

$\sqrt{(x2-x1)^2+(y2-y1)^2}$

Take the first two points, $(-1,3)(3,0)$ and insert the values:

$\sqrt{(3-(-1))^2+(0-3)^2}$

Simplify parentheses (two negatives makes a positive):

$\sqrt{(3+1)^2+(0-3)^2}\\\\ \sqrt{(4)^2+(-3)^2}\\\\\sqrt{16+9}\\ \\\sqrt{25}=5$

The distance between the first two points is 5. Use the nest two points, $(3,0)(-1,-2)$ and insert values:

$\sqrt{(-1-3)^2+(-2-0)^2}$

Simplify parentheses:

$\sqrt{(-4)^2+(-2)^2}\\ \\\sqrt{16+4} \\\\\sqrt{20}=4.5$

The distance between the nest two point is about 4.5. Use the remaining two points, $(-1,-2)(-1,3)$ and insert values:

$\sqrt{(-1-(-1))^2+(3-(-2))^2}$

Simplify parentheses (two negatives makes a positive):

$\sqrt{(-1+1)^2+(3+2)^2}\\\\\sqrt{(0)^2+(5)^2}\\ \\\sqrt{0+25}\\ \\\sqrt{25}=5$

The distance between the last points is 5. Add the distances together to find the perimeter of the triangle:

$5+4.5+5\\10+4.5\\14.5$

The perimeter is about 14.5.
