We are given with a function y and need to find dy/dx or the first Derivative of y w.r.t.x , but let's recall
[tex]{\boxed{\bf{\dfrac{d}{dx}\{f(x)\pm g(x)\pm h(x)\pm \cdots =\dfrac{d}{dx}\{f(x)\}\pm \dfrac{d}{dx}\{g(x)\}\pm \dfrac{d}{dx}\{h(x)\}\pm \cdots}}}[/tex] [tex]{\boxed{\bf{\dfrac{d}{dx}(x^n)=nx^{n-1}}}}[/tex] [tex]{\boxed{\bf{\dfrac{d}{dx}(log_{e}x)=\dfrac{1}{x}}}}[/tex] [tex]{\boxed{\bf{\dfrac{d}{dx}(e^x)=e^{x}}}}[/tex]Now consider :
[tex]{:\implies \quad \sf y=e^{x}-\dfrac{1}{x}+log_{e}x}[/tex]
Differentiating both sides w.r.t.x
[tex]{:\implies \quad \sf \dfrac{d}{dx}(y)=\dfrac{d}{dx}\bigg\{e^{x}-\dfrac{1}{x}+log_{e}x\bigg\}}[/tex]
[tex]{:\implies \quad \sf \dfrac{dy}{dx}=\dfrac{d}{dx}(e^x)-\dfrac{d}{dx}\left(\dfrac{1}{x}\right)+\dfrac{d}{dx}(log_{e}x)}[/tex]
[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}-\dfrac{d}{dx}(x^{-1})+\dfrac{1}{x}}[/tex]
[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}-(-1)(x)^{-1-1}+\dfrac{1}{x}}[/tex]
[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}+(x)^{-2}+\dfrac{1}{x}}[/tex]
[tex]{:\implies \quad \sf \dfrac{dy}{dx}=e^{x}+\dfrac{1}{x^{2}}+\dfrac{1}{x}}[/tex]
Simplifying will yield
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{\dfrac{dy}{dx}=\dfrac{e^{x}x^{2}+x^{2}+x}{x^{2}}}}}[/tex]

The geometric series which represent the provided number in the fraction form is,
[tex]\dfrac{4}{10}, \dfrac{4}{100},\dfrac{4}{1000},\dfrac{4}{10,000}[/tex]
What is geometric sequence?Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
The fraction number given in the problem is,
[tex]n=0.4444.....[/tex]
Let's break the given number into the parts as,
[tex]n=0.4+0.04+0.004+0.0004+.....[/tex]
The decimal number 0.4 is written as 4/10. Similarly, 0.04 can be written as 4/100. Thus, the above number can also be written as,
[tex]n=\dfrac{4}{10}+\dfrac{4}{100}+\dfrac{4}{1000}+\dfrac{4}{10,000}+\cdots[/tex]
Hence, the geometric series which represent the provided number in the fraction form is,
[tex]\dfrac{4}{10}, \dfrac{4}{100},\dfrac{4}{1000},\dfrac{4}{10,000}[/tex]

Answer:
2 seconds
Step-by-step explanation:
This means the height, and thus h(t), is equal to zero.
0=-16t^2 + 16t + 32
0= t^2 - t - 2 (divide both sides by -16)
0 = (t-2)(t+1) [factor]
t = -1, 2 [set each factor equal to zero]
But as time cannot negative, take t=2, giving us 2 seconds.

The quadrilateral is a rhombus. What is QT?
Step-by-step explanation:
qu = 5y - 4
and qt is half of qu
so
qt = [tex]\frac{5y - 4}{2}[/tex]
Answer:
QT = 8
Step-by-step explanation:
the sides of a rhombus are congruent , then
PS = RS ( substitute values )
3y - 1 = 2y + 3 ( subtract 2y from both sides )
y - 1 = 3 ( add 1 to both sides )
y = 4
The diagonals of a rhombus bisect each other
QS = 5y - 4 = 5(4) - 4 = 20 - 4 = 16
then
QT = [tex]\frac{1}{2}[/tex] QS = [tex]\frac{1}{2}[/tex] × 16 = 8

A buyer and seller agree that 4 blocks of salt weigh the same as 1 gold bar if this is true how many gold bars would weigh the same as 21 blocks of salt
Answer:
5.25 gold bars are needed to get it to weigh the same as 21 gold bars.
Step-by-step explanation:
ratio = 4 blocks of salt : 1 gold bar
to get the amount of gold bars needed to weight the same amount as 21 blocks of salt divide 21 by 4
21 ÷ 4 = 5.25
21 blocks of salt : 5.25 gold bars
5.25 gold bars are needed to get it to weigh the same as 21 gold bars.

The answer is 49 inches
Step-by-step explanation:
Divide 294 by 6 to get the answer.
Hope that helps!
Answer:
49 inches
We know that for every 6 feet in real life, there will be 1 inch in the picture.
So, that means if we divide 294 by 6, we can find how many inches wide the picture is.
294 ÷ 6 = 49
Since there are 49 sixes in 294, the picture is 49 inches wide.
Using a minimum of three points, create two linear functions. Prove the line created works exclusively with the three points by justifying how the x-value and y-value fit into the equation for the line.
The equation of the line passing through the point (-1, 1) and (0, 10) is y = 9x + 10
What is a linear function?A linear function is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
From the table, using the point (-1, 1) and (0, 10) ,hence:
[tex]y-1=\frac{10-1}{0-(-1)} (x-(-1))\\\\y=9x+10[/tex]
