## How to find vector between 2 points not in reference to the origin ?

Hello, I have 2 points (A and B) in 3D space. I have the coordinate for them A(**x1**,y1,z1) and B (x2,y2,z2). I want to find the vector that connect them not in reference to the origin but in reference to the point B. Could someone help me with some tips ?

Thanks,

Victoria

The vector must be non unit.

### Administrator answers:

Parametrically, the vector V can be represented by:

V(t) = B + t*

Note that when t=1,

V(t) = + = = A

## What is the distance the lower spring is stretched from its equilibrium length?

A single mass m1 = 3.6 kg hangs from a spring in a motionless elevator. The spring is extended x = 15.0 cm from its unstretched length.

Now, three masses m1 = 3.6 kg, m2 = 10.8 kg and m3 = 7.2 kg hang from three identical springs in a motionless elevator. The springs all have the same spring constant that you just calculated above.

1) What is the distance the lower spring is stretched from its equilibrium length?

2) Now the elevator is moving downward with a velocity of v = -3.0 m/s but accelerating upward with an acceleration of a = 3.8 m/s2. (Note: an upward acceleration when the elevator is moving down means the elevator is slowing down.)

What is the force the bottom spring exerts on the bottom mass?

3) What is the distance the upper spring is extended from its unstretched length?

4) Rank the distances the springs are extended from their unstretched lengths:

a) **x1** = x2 = x3

b) **x1** > x2 > x3

c) **x1** < x2 < x3

5) What is the distance the MIDDLE spring is extended from its unstretched length?

6) Finally, the elevator is moving downward with a velocity of v = -3.4 m/s and also accelerating downward at an acceleration of a = -2.1 m/s2.

a)speeding up

b)slowing down

c)moving at a constant speed

### Administrator answers:

1) The distance the lower spring is stretched from its equilibrium length is 45cm because the weight is 3x as much as the reference spring and the spring constant is the same.

2) The force the bottom spring exerts on the mass is its weight (=mg) PLUS 10.8kg x 3.8m/s^2 = 133N

3) The distance the upper spring is extended from its unstretched length when not accelerated is 15cm

4) Rank the distances the springs are extended from their unstretched lengths:

c) x1 < x2 < x3

5) The distance the MIDDLE spring is extended from its unstretched length when not accelerated is 45cm

6) Finally, the elevator is moving downward with a velocity of v = -3.4 m/s and also accelerating downward at an acceleration of a = -2.1 m/s2.

A)speeding up

because the v and a are in the same direction

Steven asks…

## How to solve the inverse of these functions?

I’d like to solve the inverse of the functions:

f(**x1**)= root (1-x^2) 0 ? x ? 1

f(x2) = root (1-x^2) -1 ? x ? 0

f(x3) = – root (1-x^2) -1 ? x ? 0

f(x4)= – root (1-x^2) 0 ? x ? 1

My student solution manual goes over only the odd numbers, and, unfortunately, this is an even number question. Please help in simple, basic steps.

### Administrator answers:

F(x1)=y = ?(1-x²)

exchange x and y

x=?(1-y²)

x² =1-y²

y² = 1-x²

y=±?(1-x²)

plot then compare the graphs

## Can the turtle beach ear force x1 headset be used with an HDMI setup?

Can the turtle beach ear force **x1** headset be used with an HDMI setup?

does the 360 60gb come with av cables?

### Administrator answers:

Nope. The closest thing like to that is the optical cable on the x4 model that came out recently. Sorry.

Chris asks…

## How to Identify the 2 points so I could calculate the slope on a graph?

I really need help because, i know how to calcutate a slope already but i dont know how to find the points on the graph so i can use it to calculate it.

For ex: y1-x2/y1-y2

How am i suppose to find what y1 and y2 and **x1** and x2 is on a GRAPH??? Please help me!

### Administrator answers:

First, the slope formula is y2 – y1 / x2 – x1.

Do you have the y = mx + b expression?

If you do, then you can just plug in two numbers for x and get y from there.

Other than that, I guess you can use the x and y-intercepts; they usually tend to be easy to find as (usually) they’re integers.

Ken asks…

## How to find standard form when given two points?

So, I know the equation is y-y1=m(x-**x1**)

and i understand you must find slope, but after plugging in slope, I don’t understand how

to solve the problem. For example, points (1,2) (3,4) how would you put it in standard form Ax+By=C?

### Administrator answers:

So, you’d get the slope: (4 – 2)/(3 – 1) = 2/2 = 1

Choose either point to be (x1, y1), say you choose (1,2)

y – 2 = 1(x – 1)

Distribute

y – 2 = x – 1

Add -y to both sides

-2 = x – y – 1

Add 1 to both sides

-1 = x – y

Switch it around

x – y = -1

Ruth asks…

## How do I find the y intercept when I have a slope and two points on a line?

I have points (14, 45) and (24, 47). I know slope is (y1-y2)/(**x1**-x2) but how do I find the y-intercept?

### Administrator answers:

M = slope

m = 2/10

m = 1/5

y- y1 = m (x – x1)

y- 45 = m (x – 14)

y- 45 = 1/5 (x – 14)

y – 45 = 1/5x – 2.8

y = 1/5x + 47.8 —- thats the answer
