10) Find the distance between (2, 3) and (-3, -2) A) 2 B) 5 C) 50 = 5 2 D) 25

PSYCHO15rus [73]

Answer:

The answer is

<h2> $5 \sqrt{2} \: \: \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

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

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(2, 3) and (-3, -2)

The distance between them is

$d = \sqrt{( {2 + 3})^{2} + ({3 + 2})^{2} } \\ = \sqrt{ {5}^{2} + {5}^{2} } \\ = \sqrt{25 + 25} \\ = \sqrt{50} \\ = 5 \sqrt{2}$

We have the final answer as

$5 \sqrt{2} \: \: \: \: units$

Nine cards are numbered from 1 to 9 and placed in a box. One card is selected at random and not replaced. Another card is random

irakobra [83]

Answer: 1/6

Step-by-step explanation: There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.

When a coordinate grid is superimposed on a map of lanesville the middle school is located at (15,13) and the librart is located

Maksim231197 [3]

Answer:

4.5 miles

Step-by-step explanation:

Given

$Middle\ School = (15,13)$

$Library = (27,9)$

To solve this, we simply solve for the distance (D) between both points.

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

Where:

$(x_1,y_1) = (15,13)$

$(x_2,y_2) = (27,9)$

$D = \sqrt{(27 - 25)^2 + (9 - 13)^2}$

$D = \sqrt{(2)^2 + (-4)^2}$

$D = \sqrt{4 + 16}$

$D = \sqrt{20}$

$D=4.472135955$

<em></em> $D=4.5$ <em> --- approximated</em>

<em>Since each unit is 1 mile. The distance is 4.5 miles</em>
