How do we know that the derivative of 1/x is equal to -1/x^2 ?

snow_lady [41]

Answer:the derivative of 1/x =-1/x^2

Step-by-step explanation:

1/x can also be written as x^-1

Therefore d/dx of x^-1

=-1*x^-1-1

=-1x^-2

Which can also be written as -1/x^2

Note: d/dx also means derivative of x

And d/dx (a/x^b) =(a*-b) /x^(b+1)

Where a and b represents a variable

What is greater 16/25 or 65%

slega [8]

Hi there!

»»————-　★　————-««

I believe your answer is:

65% has the greater value.

»»————-　★　————-««

Here’s why:

We can convert both numbers into decimals and then compare the values.

⸻⸻⸻⸻

$\boxed{\text{Comparing Numbers:}}\\\\-------------\\\rightarrow\frac{16}{25}= 0.64\\\\\rightarrow 65\%=\frac{65}{100}=0.65\\ -------------\\\\\boxed{0.65 > 0.64}\\\\\text{Therefore:}\\\\\boxed{65\% > \frac{16}{25}}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
