ivann1987 [24]

Answer:

$= \frac{-2(x-6)}{(x+4)(x-4)}$

Step-by-step explanation:

Given the expression;

$\frac{x}{x^2-16} -\frac{3}{x-4}$

According to difference of two square;

x² - 16 = x²-4² = (x+4)(x-4)

Substitute;

$\frac{x}{(x+4)(x-4)} - \frac{3}{x - 4}\\$

Find the LCM

$= \frac{x-3(x+4)}{(x+4)(x-4)} \\= \frac{x-3x-12}{(x+4)(x-4)}\\= \frac{-2x-12}{(x+4)(x-4)}\\= \frac{-2(x-6)}{(x+4)(x-4)}$

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
