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

A stockbroker earns a base salary of 40000 dollar plus 5%of the total value of the stocks,mutual funds , and other investments t
lisabon 2012 [21]
Well his salary is $40,000 dollars.

$72,750 - $40,000 = $32,750

This means that 5% of the value of investments he had sold was equal to $32,750.

\frac { 1 }{ 20 } \times I=32750\\ \\ 20\times \frac { 1 }{ 20 } \times I=20\times 32750\\ \\ \therefore \quad I=655000

The stockbroker sold $655,000 worth of investments.

Line M is represented by the following equation: x + y =-1
BaLLatris [955]

Answer:

2x+ 2y = -2

Step-by-step explanation:

Given the equation of a line as x + y = -1

To get the equation of the line P so the set of equations has infinitely many solutions, we will have to multiply the given equation by a factor

Multiplying the given equation by a factor of 2;

Given x + y = -1

Multiplying both sides by 2;

2(x + y) = 2(-1)

2x+ 2y = -2

Hence the required equation is 2x+ 2y = -2
