Answer:

2630

Step-by-step explanation:

5.6*(10^6) - 340,000 / 2*(10^3)

5,600,000 - 340,000 / 2,000

5,260,000 / 2000

= 2630 or 2.63*(10^3)

What is the derivative of ln(lnx^3)
chubhunter [2.5K]

the derivative of ln(lnx^3) is \frac{1}{x(lnx)} .

<u>Step-by-step explanation:</u>

Here we have to find the derivative of ln(lnx^3) , Let's find out:

We have , ln(lnx^3) , Let's differentiate it w.r.t x :

⇒ \frac{d(ln(lnx^3))}{dx}

Let lnx^3 = u

⇒ \frac{d(ln(u))}{dx}

⇒ \frac{1}{u} (\frac{d(u)}{dx} )

⇒ \frac{1}{u} (\frac{d(ln(x^3))}{dx} )

Let x^3=v

⇒ \frac{1}{u} (\frac{d(ln(v))}{dx} )

⇒ \frac{1}{u}(\frac{1}{v} ) (\frac{d(v)}{dx} )

⇒ \frac{1}{u}(\frac{1}{v} ) (\frac{d(x^3)}{dx} )            

⇒ 3x^2(\frac{1}{u})(\frac{1}{v} )

Putting value of u & v we get:

⇒ 3x^2(\frac{1}{lnx^3})(\frac{1}{x^3} )

⇒ \frac{3}{x(lnx^3)}    { lnx^n = n(lnx)  }

⇒ \frac{3}{3x(lnx)}

⇒ \frac{1}{x(lnx)}

Therefore , the derivative of ln(lnx^3) is \frac{1}{x(lnx)} .

PLEASE HELP WILL MARK BRAINLIEST
LekaFEV [45]

Step-by-step explanation:

In trapezoid ABCD, it is given that:

AE = BE & DF = CF

Hence, points E and F are the mid points of the sides AB and CD respectively.

We know that:

In a trapezoid length of the line segment joining the mid points of non parallel sides is equal to one half of the sum of lengths of the parallel sides.

\therefore \: 4x =  \frac{1}{2}  \{(x + 5) + 44 \} \\  \\  \therefore \: 4x =  \frac{1}{2}  \{x + 5 + 44 \} \\  \\ \therefore \: 4x  \times 2=  \{x + 49\} \\  \\ \therefore \: 8x =  x + 49 \\  \\  \therefore \: 8x  -  x  =  49 \\  \\  \therefore \: 8x  -  x  =  49 \\  \\ \therefore \:7x = 49 \\  \\ \therefore \:x =  \frac{49}{7}  \\  \\  \therefore \:x =  7\\  \\ \therefore \:4x = 4\times 7.. (\because EF = 4x)\\  \\   \:  \:  \:  \:  \: \huge \red{ \boxed{\therefore \:EF =  28}}
