2i√5

Explanation:
When using square root on a negative, simply take out the negative and use an i. This way, the equation is i√20.
Simplify the 20 by taking out 4 and 5.

i√4*5
Since the square root of 4 is 2, you can take out the 4 and replace it with a 2 on the outside.
2i√5

Hope this helps! Please give brainliest if you can :)

Answer:

Systematic sampling.

Step-by-step explanation:

The systematic sampling is a type of random sampling in which a unit is selected from k units and after this every kth unit is selected until population is serially numbered from 1 to N arranged in a systematic way.

The statement shows that every 18th truck is selected until a sample of 60 trucks is selected. It shows that a systematic random sample is obtained with k=18 and thus, systematic sampling is used.

Use the definition of the derivative to differentiate f(x)= In x

WINSTONCH [101]

By def. of the derivative, we have for y = ln(x),

$\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac{\ln(x+h)-\ln(x)}{h}$

$\displaystyle \frac{dy}{dx} = \lim_{h\to0} \frac1h \ln\left(\frac{x+h}{x}\right)$

$\displaystyle \frac{dy}{dx} = \lim_{h\to0} \ln\left(1+\frac hx\right)^{\frac1h}$

Substitute y = h/x, so that as h approaches 0, so does y. We then rewrite the limit as

$\displaystyle \frac{dy}{dx} = \lim_{y\to0} \ln\left(1+y\right)^{\frac1{xy}}$

$\displaystyle \frac{dy}{dx} = \frac1x \lim_{y\to0} \ln\left(1+y\right)^{\frac1y}$

Recall that the constant e is defined by the limit,

$\displaystyle e = \lim_{y\to0} \left(1+y\right)^{\frac1y}$

Then in our limit, we end up with

$\displaystyle \frac{dy}{dx} = \frac1x \ln(e) = \boxed{\frac1x}$

In Mathematica, use
