Find dy/dx using first principle<br>x+1/x

JulsSmile [24]

Answer:

The derivative of the function is:

$f'(x)=1-\frac{1}{x^{2}}$

Step-by-step explanation:

The first principle is given by:

$f'(x)=\frac{dy}{dx}=lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}$

The function here is:

$f(x)=x+\frac{1}{x}$

Now, using the first principle we have:

$f'(x)=lim_{h\rightarrow 0}\frac{(x+h)+\frac{1}{(x+h)}-x-\frac{1}{x}}{h}$

$=lim_{h\rightarrow 0}\frac{h+\frac{1}{(x+h)}-\frac{1}{x}}{h}$

$=lim_{h\rightarrow 0}\frac{h-\frac{h}{x(x+h)}}{h}$

$=lim_{h\rightarrow 0}\frac{h(1-\frac{1}{x(x+h)})}{h}$

$=lim_{h\rightarrow 0}1-\frac{1}{x(x+h)}$

$=1-\frac{1}{x^{2}}$

Therefore, the derivative of the function is:

$f'(x)=1-\frac{1}{x^{2}}$

I hope it helps you!

Brittany and Natalie, start cycling together from their home to school, which is 14.4 miles away. Natalie takes 40 minutes to re

prohojiy [21]

Answer:

7.2

Step-by-step explanation:

1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.

2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph

3. The difference 21.6-14.4=7.2 is the answer .

A rectangular lot has an area of 240m. What is the width of the lot if it requires 64m of fencing materials to enclosed it ?.

nirvana33 [79]

Answer:

Confusing but I got the width is either 12 or 20

12 × 20 = 240 = area check

64 = perimeter = 12 + 12 + 20 + 20 = check

it does not give specifics on what is length so it's one of the 2 which ever one is the width the other is length

An ant needs to travel along a 20cm × 20cm cube to get from point A to point B. What is the shortest path he can take, and how l

malfutka [58]

Answer:

1. Along a diagonal, and then along an edge.

2. 48.28 cm.

Step-by-step explanation:

Assume points A and B are at diagonally opposite corners, as in the diagram below.

1. Shortest path

The shortest path is to go along the diagonal AC and continue along the edge CB.

2. Distance

The distance travelled is

d = AC + CB

According to Pythagoras,

AC² = AD² + CD² = 20² + 20² = 400 + 400 = 800

AC = √800 = 20√2

d = AC + CB = 20√ 2+ 20 ≈ 2 × 1.414 + 20 = 48.28 cm

The ant travels 48.28 cm.
