(2, 7) and (-6, -2) find the distance between each pair of points

yaroslaw [1]

Answer:

$\sqrt{145}$

Step-by-step explanation:

Hi there!

We are given the points (2, 7) and (-6, -2). We want to find the distance between them. To do that, we can use the distance formula

The distance formula is given as $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ , where $(x_1, y_1)$ and $(x_2, y_2)$ are points

We have 2 points, which is what we need to find the distance, but let's label their values to avoid any confusion

$x_1=2\\y_1=7\\x_2=-6\\y_2=-2$

Now substitute those values into the formula:

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\sqrt{(-6-2)^2+(-2-7)^2}$

Simplify the values under the radical:

$\sqrt{(-8)^2+(-9)^2}$

Raise to the second power:

$\sqrt{64+81}$

Add the numbers under the radical together

$\sqrt{145}$

The answer can be left as that, as the radical cannot be simplified.

Hope this helps!

A male punky fish has 9 stripes and a female punky fish has 8 stripes.I count 86 stripes on the fish in my tank.What is the rati

Andrews [41]

The ratio of male fishes to female fishes is 3 : 2

Solution:

Given, male punky fish = 9 stripes

Female punky fish = 8 stripes.

Total stripes = 86

Finding the ratio of male fish to female fish:

Let the number of male fishes be "m", and the number of female fishes be "n"

The, given that, total strips = 86

which means, total male strips + total female stripes = 86

$\text { 9 stripes per male } \times \text { number of male fishes }+8 \text { stripes for female } \times \text { number of female fishes }=86$

$\begin{array}{l}{\rightarrow 9 \times m+8 \times n=86} \\\\ {\rightarrow 9 m+8 n=86}\end{array}$

The only values that can satisfy above equation are m = 6 and n = 4

Now, ratio of male fishes to female fishes = m : n = 6 : 4 = 3 : 2

Hence, the ratio of male fishes to female fishes is found out as 3 : 2
