<span>Students are given two arrays, one representing the equation 7 x 9 = 63 and the other representing the equation (5 + 2) x 9 = 63, to see if they recognize a relationship between the two.

Find the sum of the following numbers without actually adding them1+3+5+7+9+11+13+15

Dovator [93]

S = 1 + 3 + 5 + ... + 11 + 13 + 15

S = 15 + 13 + 11 + ... + 5 + 3 + 1

==> 2S = (1 + 15) + (3 + 13) + (5 + 11) + ... + (15 + 1)

There are 8 terms in the sum, so

2S = 8 * 16 = 128

S = 128/2 = 64

Find the distance between points A (10,-1) and B (-2,5). Round to the nearest tenth

bija089 [108]

Answer:

<h2>The answer is 13.4 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

A (10,-1) and B (-2,5)

The distance is

$|AB| = \sqrt{ ({10 + 2})^{2} + ({ - 1 - 5})^{2} } \\ = \sqrt{ {12}^{2} + ({ - 6})^{2} } \\ = \sqrt{144 + 36} \: \: \: \: \: \: \: \\ = \sqrt{180} \\ = 6 \sqrt{5} \: \: \\ =13.416407$

We have the final answer as

<h3>13.4 units to the nearest tenth</h3>

Hope this helps you
