find dy/dx using first principle
x+1/x
Answer:
The derivative of the function is:
[tex]f'(x)=1-\frac{1}{x^{2}}[/tex]
Step-by-step explanation:
The first principle is given by:
[tex]f'(x)=\frac{dy}{dx}=lim_{h\rightarrow 0}\frac{f(x+h)-f(x)}{h}[/tex]
The function here is:
[tex]f(x)=x+\frac{1}{x}[/tex]
Now, using the first principle we have:
[tex]f'(x)=lim_{h\rightarrow 0}\frac{(x+h)+\frac{1}{(x+h)}-x-\frac{1}{x}}{h}[/tex]
[tex]=lim_{h\rightarrow 0}\frac{h+\frac{1}{(x+h)}-\frac{1}{x}}{h}[/tex]
[tex]=lim_{h\rightarrow 0}\frac{h-\frac{h}{x(x+h)}}{h}[/tex]
[tex]=lim_{h\rightarrow 0}\frac{h(1-\frac{1}{x(x+h)})}{h}[/tex]
[tex]=lim_{h\rightarrow 0}1-\frac{1}{x(x+h)}[/tex]
[tex]=1-\frac{1}{x^{2}}[/tex]
Therefore, the derivative of the function is:
[tex]f'(x)=1-\frac{1}{x^{2}}[/tex]

1. A new company wants to mail out samples of its hair products. The company has a sample box that is a rectangular prism with a rectangular base with
an area of 23 1/3 sq. in. The height of the prism is 1 1/4 in. Determine the volume of the sample box
A.24 7/12 sq. inches
B. 24 7/12 cubic inches
C.175/6 sq. inches
D. 175/6 cubic inches
Answer:
Volume of rectangular prism = 175 / 6 inch³
Step-by-step explanation:
Given:
Base area of rectangular prism = 23 ¹/₃ inch² = 70 / 3 inch²
Height of rectangular prism = 1 ¹/₄ inch = 5 / 4 inch
Find:
Volume of rectangular prism
Computation:
Volume of rectangular prism = Base area of rectangular prism x Height of rectangular prism
Volume of rectangular prism = [70 / 3] x [5 / 4]
Volume of rectangular prism = [350 / 12]
Volume of rectangular prism = 175 / 6 inch³

Answer:
x=6
Step-by-step explanation:
x+54+5x=90
6x+54=90
6x=36
x=6
Answer:
x=6
Step-by-step explanation:
So, lets go over what we know.
Angle 5x and angle x+54 make up 90 degrees.
We know its 90 degrees since there is a square like symbol on the side of the line.
To sovle for x, we must add the two angles together. This will make them equivelent to 90 degrees.
So:
5x+x+54=90
=
6x+54
Now that we combined our two angles, we can solve it like a normal equation:
6x+54=90
subtract 54 from both sides to get 6x alone:
6x=36
Now divide both sides by 6 so x is alone:
x=6
So now we know that x=6.
If you wan to check your answer, just look at the orginal graph, plug in 8 for x, and see if the two angles add up to 90:
Angle 5x:
5*6
=
30
Angle x+54
6+54
=
60
Add the two angles together:
30+60
=
90
So we have checked and the answer is still correct!
Hope this helps! :D

You roll a six-sided number cube and flip a coin what is the probability of rolling a number greater than 3 and flipping heads? Write your answer as a fraction in simplest form.
Answer:
1/4
Step-by-step explanation:
Possible outcomes from rolling the cube that satisfy the "greater than 3" criterion are {4, 5, 6} out of a total of six possibilities {1, 2, 3, 4, 5, 6}. Thus, the probability of rolling a number greater than 3 is 3/6, or 1/2.
Probability of flipping heads is 1/2.
These are entirely independent events. Thus, the joint probability is (1/2)(1/2), or 1/4.

Rajib wrote the equations y = 8 x minus 2 and y = negative 4 x minus 5. What can Rajib conclude about the solution to this system of equations? The point (2, 14) is a solution to this system of equations. The point (14, 2) is a solution to this system of equations. The point (Negative 4, negative one-fourth) is a solution to this system of equations. The point (Negative one-fourth, negative 4) is a solution to this system of equations.
Answer:
The point (Negative 4, negative one-fourth) is a solution to this system of equations
Step-by-step explanation:
y = 8x - 2
y = - 4x - 5
y - 8x = - 2 - - (1)
y + 4x = - 5 - - - (2)
Subtract 1 and 2
-8x - 4x = - 2 - (-5)
-8x - 4x = 3
-12x = 3
x = - 1/4
y = 8(-1/4) - 2
y = - 2 - 2
y = - 4
(-1/4, - 4)
