If lnx + ln(x−3)= ln(4x), then x=

bazaltina [42]

Answer:

x=7

Step-by-step explanation:

ln(x)+ln(x-3)=ln(4x)

x≥0,x≥3

combining x≥3

ln[x(x-3)]=ln(4x)

x(x-3)=4x

x²-3x-4x=0

x²-7x=0

x(x-7)=0

x=0(rejected),7

Look at the figure and answer

andreyandreev [35.5K]

Answer:

$\cos x=\dfrac{8}{f}$

Step-by-step explanation:

Given that,

$\tan x=\dfrac{e}{8}\\\\\sin x=\dfrac{e}{f}$

We need to find the value of cos x.

We know that,

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}$

Using the above relation,

$\dfrac{e}{8}=\dfrac{\dfrac{e}{f}}{\cos x}\\\\\cos x=\dfrac{\dfrac{e}{f}}{\dfrac{e}{8}}\\\\=\dfrac{e}{f}\times \dfrac{8}{e}\\\\=\dfrac{8}{f}$

So, the value of cos x is equal to $\dfrac{8}{f}$ .
