Step-by-step explanation:</h3>
It depends on where you are.
In the US, standard form is the way you have written the number. Your number would be 6,301.005.
The attachment gives some guidance for number formats in American publications. In certain publications, thin spaces are used instead of commas to separate groups of digits. The comma (or space) is often optional, but can enhance readability for large numbers.
In Britain, standard form is the form called "scientific notation" in the US. Your number would be 6.301005×10³.
Answer:
<h2><u><em>
2x + 6</em></u></h2>
Step-by-step explanation:
Simplify: (x + 3)*(+ 2)
(x + 3)*(+ 2) =
2x + 6
We have been given the expression to be ![y=(x-3)^7(x+1)^2](https://tex.z-dn.net/?f=%20y%3D%28x-3%29%5E7%28x%2B1%29%5E2%20)
Since we need to find the tangent at a point, we will have to find the derivative of
as the slope of the tangent at a given point on the curve is always equal to value of the derivative at that point.
Thus, we have to find ![\frac{dy}{dx}=\frac{d}{dx} (x-3)^7(x+1)^2](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdy%7D%7Bdx%7D%3D%5Cfrac%7Bd%7D%7Bdx%7D%20%28x-3%29%5E7%28x%2B1%29%5E2%20%20%20)
We will use the product rule of derivatives to find ![\frac{dy}{dx}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bdy%7D%7Bdx%7D%20%20)
Thus,
(using the product rule which states that
)
Taking the common factors out we get:
![y'=(x-3)^6(x+1)(7(x+1)+2(x-3))](https://tex.z-dn.net/?f=%20y%27%3D%28x-3%29%5E6%28x%2B1%29%287%28x%2B1%29%2B2%28x-3%29%29%20)
![y'=(x-3)^6(x+1)(7x+7+2x-6)=(x-3)^6(x+1)(9x+1)](https://tex.z-dn.net/?f=%20y%27%3D%28x-3%29%5E6%28x%2B1%29%287x%2B7%2B2x-6%29%3D%28x-3%29%5E6%28x%2B1%29%289x%2B1%29%20)
Thus,
at
is given by:
=Slope of the tangent of y at x=4=![m](https://tex.z-dn.net/?f=%20m%20)
Thus, ![m=(4-3)^6(4+1)(9\times4+1)=185](https://tex.z-dn.net/?f=%20m%3D%284-3%29%5E6%284%2B1%29%289%5Ctimes4%2B1%29%3D185%20)
Now, the equation of the tangent line which passes through
and has slope m is given by:
![y-y_{1}=m(x-x_{1})](https://tex.z-dn.net/?f=%20y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%29%20%20%20)
Thus, the equation of the tangent line which passes through
and has the slope 185 is![y-25=185(x-4)](https://tex.z-dn.net/?f=%20y-25%3D185%28x-4%29%20)
Which can be simplified to ![y=185x-740+25=185x-715](https://tex.z-dn.net/?f=%20y%3D185x-740%2B25%3D185x-715%20)
Thus, ![y=185x-715](https://tex.z-dn.net/?f=%20y%3D185x-715%20)
This is the required equation of the tangent.
