Answer:
y = x - 8
Step-by-step explanation:
In the equation for slope, y = mx + b,
your slope being 0 makes the equation 'x' or 0x but x is preffered.
Your why would be -8 because there is no x in the point and it is a negative number.
The measure of x in both parts is: 120°
Step-by-step explanation:
Part A:
We can clearly see that the figure in part a has six equal sides. So the given figure is a hexagon.
A hexagon has six equal sides in six equal interior angles.
Sum of interior angles of hexagon is 720°
So,
Part B:
The figure is a Dodecagon with 12 sides.
The Dodecagon has 12 equal sides and angles.
The sum of internal angles of Dodecagon is 1440°
So,
The measure of x in both parts is: 120°

Answer:
-(1/4πϵ0)Qq/r^2
Step-by-step explanation:
Firstly we have to assume the uniform shell of radius R as point charge as the point charge.
Then apply coulomb equation of electrostatic charge (Fe=q1q2/4πϵ0r2) where the q1 and q2 are point charges and r is the distance from the centre of charges.
But remember there's a condition that r>>R otherwise the charge will get non-uniformely distributed.
By laplace transform definition of { t^n * f(t) }
<span>(-1)^n * ( d^n/ds^n ) F(s) </span>
<span>t^2*sin(2t) <==== let's apply it </span>
<span>(-1)^2 * ( d^2/ds^2 ) ( 2 / (s^2 + 2^2) ) </span>
<span>1 * ( d^2/ds^2 ) ( 2 / (s^2 + 4) ) <===== let's find the first and second derivative : </span>
<span>( (s^2 + 2^2) * 0 - 2 * (2s) / (s^2 + 4)^2 ) </span>
<span>( - 4s) / (s^2 + 4)^2 ) <==== let's find the second derivative </span>
<span>( (s^2 + 4)^2 * -4 - - 4s * 2 * (s^2 + 4) * 2s ) / (s^2 + 4)^4 ) </span>
<span>( -4(s^2 + 4)^2 + 16s^2 * (s^2 + 4) ) / (s^2 + 4)^4 ) </span>
<span>( -4(s^2 + 4) + 16s^2 ) / (s^2 + 4)^3 ) </span>
<span>( -4s^2 - 16 + 16s^2 ) / (s^2 + 4)^3 ) </span>
<span>( 12s^2 - 16 ) / (s^2 + 4)^3 )
