Find the distance between (3,-3) and (2,7)

yarga [219]

Answer:

$\sqrt{101} = D$

Step-by-step explanation:

Method #1

We can draw a right triangle on the graph upon where the points are located and use the Pythagorean Theorem:

${a}^{2} + {b}^{2} = {c}^{2}$

${1}^{2} + {10}^{2} = {c}^{2}$

$1 + 100 = {c}^{2}$

$101 = {c}^{2}$

$\sqrt{101} = c$

* Whenever we talk about distance, we ONLY want the NON-NEGATIVE root.

_______________________________________________

Method #2

Or, we can use the Distance Formula:

$\sqrt{[-x_1 + x_2]^{2} + [-y_1 + y_2]^{2}} = D$

[2, 7] [3, −3]

$\sqrt{[-3 + 2]^{2} + [3 + 7]^{2}} = D$

$\sqrt{[-1]^{2} + 10^{2}} = D$

$\sqrt{1 + 100} = D$

$\sqrt{101} = D$

** You see? It does not matter which method you choose, as long as you are doing the work correctly.

Solve w = t(r1 + r2) for t.

kiruha [24]

I think it would be:

w / (r1 + r2) = t

To make a shade of purple called "Grape Purple" you must mix red and blue paint together with a ratio of 2:3. Miya mixed 8 cups

Viktor [21]

Answer: She will get a different shade

Step-by-step explanation:

She will not get "Grape Purple" here is why:

The ratio of red to blue cups can be expressed as a fraction of:

2/3

If we express Miya's mix as a fraction we get:

8:14

If we simplify that it becomes:

4/7

4/7 is not equal to 2/3.
