Using the Distance Formula, find the distance between points (-1, -7) and (-3,-5) to the nearest tenth.
MrMuchimi

Answer:

The answer is

<h2>2.8</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

(-1, -7) and (-3,-5)

The distance between them is

d =  \sqrt{ ({ - 1 + 3})^{2}  +  ({ - 7 + 5})^{2} }  \\  =  \sqrt{ {  2}^{2}  + ( { - 2})^{2} }  \\  =  \sqrt{4 + 4}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  =  \sqrt{8}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\   = 2 \sqrt{2}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \\  = 2.8284271247

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you

Find n(A) of the set {-3,-1,1,3,5,7,9}
daser333 [38]

Answer:

n(A) = 7

Step-by-step explanation:

Let set A be A = {a,b,c}

We can say n(A) = 3

So basically n(A) means the "number of elements (unique) in set A"

They have to be unique.

For this problem, set A is:

A = {-3,-1,1,3,5,7,9}

If we count, there are 7 unique elements in this set. Thus:

n(A) = 7
