Find the value of a so that the differential equation y ' − xy − 6x = 0 has a solution of the form y(x) = a + bex2/2 for any con

SVEN [57.7K]

Hello,

$y=a+be^\frac{ x^{2} }{2} \\\\

y'=a'+b*x*e^\frac{ x^{2} }{2} \\\\

y'-xy-6x=0\\\\

a'+b*x*e^\frac{ x^{2} }{2}-b*x*e^\frac{ x^{2} }{2}-ax-6x=0\\\\

a'=x(a+6)\\\\

 \dfrac{a'}{a+6} =x\\\\

ln (a+6)= \dfrac{x^2}{2} +c\\\\

a=k*e^\frac{ x^{2} }{2}-6\\\\

Answer:

Step-by-step explanation:

Given the intensity of the transmitted light It and θ are related by the equation Cosθ= √ Io/It, we are to write lt as a function of lo

Given the equation

Cosθ= √ Io/It

Let us make lt the subject of the formula;

square both sides of the equation

(Cosθ)²= (√ Io/It)²

cos²θ = lo/lt

cross multiply

ltcos²θ = lo

divide both sides by cos²θ

ltcos²θ/ cos²θ= lo/cos²θ

lt = lo/cos²θ

Hence the expression of lt as a function of lo is lt = lo/cos²θ

I need help with the slope of this line.

GrogVix [38]

The slope is 0.

The formula to find the slope is y2-y1 over x2-x1. If you plug in your numbers, you should have 5-5 over 9-10. Subtract this and you will get your slope!
