What is the the distance between a point at (-3,4) and a point at (2,-5)

zaharov [31]

<h2>Question:-</h2>

What is the distance between a point at (-3,4) and a point at (2,-5) ?

<h2>Solution:-</h2>

Let the two points be A and B .

And, let the distance be P .

Now, the distance P between the point A (-3,4) and the point B (2,-5) is

$\bf P \: = \sqrt{(-3 \: - \: 2)^2 \: + \: (4 \: + \: 5)^2}$

$\implies$ $\bf P \: = \sqrt{(-5)^2 \: + \: (9)^2}$

$\implies$ $\bf P \: = \sqrt{25 \: + \: 81}$

$\implies$ $\bf P \: = \sqrt{106}$

$\implies$ $\bf P \: = \: 10.3$

<h3>The distance between a point at (-3,4) and a point at (2,-5) is 10.3 . [Answer]</h3>

Andre runs for 35 seconds at a velocity of -8 meters per second. He is running west. What is his finishing position?

user100 [1]

Answer:

d = -280 m

Step-by-step explanation:

Given that,

Velocity of Andre, v = -8 m/s

Time taken, t = 35 seconds

We need to find his finishing position. Let the finishing position be x.

We know that,

Velocity = distance/time

So,

$d=v\times t\\\\d=-8\times 35\\\\=-280\ m$

so, he was at a distance of 280 m in west.

<h2>Good morning,</h2>

Answer:

The quadratic equation is : x²+x+1=0

Step-by-step explanation:

Generally:

let S be the sum of the roots z₁ and z₂

and P be the product of the roots z₁ and z₂

then z₁ and z₂ are the solutions for the equation: x² − Sx + P = 0

Now,

S=-1 and P=1 then the equation is x²+x+1=0.
