The new polynomial identity is 2(x² + 2xy + y²)

Given,

The polynomial identities

Column A    Column B

(x − y)             (x2 + 2xy + y2)

(x + y)             (x2 − 2xy + y2)

(y + x)             (ax + b)

(y − x)             (cy + d)

We have to square an identity from column A and add it with any one identity from column B.

So,

Lets take (x + y)      

(x + y)² = x² + 2xy + y²

We can add this identity with x² + 2xy + y² in column B.

That is,

x² + 2xy + y² + x² + 2xy + y²

= 2x² + 4xy +2 y²

= 2(x² + 2xy + y²)

That is,

The new polynomial identity is 2(x² + 2xy + y²)

While passing a slower car on the highway, i accelerate uniformly from 12 m/s to 24 m/s in a time of 10.0s. How far do you trave
Taya2010 [7]
You say that there is uniform acceleration so:

vf-vi=at  (final velocity minus initial velocity is equal to acceleration times time)

We know vf, vi, and t so we can solve for acceleration:

24-12=a10

12=10a

a=1.2

That is the acceleration, we will need to integrate with respect to time twice...

v=⌠a dt

v=at+vi  , we know a=1.2m/s^2 and vi=12m/s

v=1.2t+12, 

x=⌠1.2t+12 dt

x=1.2t^2/2+12t+xo, we can just let xo=0 for this problem...

x(t)=0.6t^2+12t

Now we know that this acceleration lasts for 10 seconds so the distance traveled in that time is:

x(10)=0.6(10^2)+12(10)

x(10)=60+120

x(10)=180 meters
