Evaluate the indefinite integral. (Use C for the constant of integration.) <br> ex 5 ex dx.
melisa1 [442]

Answer:

  5 e^{x} +C

where C is constant of integration

Step-by-step explanation:

<u><em>Explanation:-</em></u>

<em>Given f(x) = 5 eˣ</em>

Now integrating with respective to 'x' , we get

                                                      I =  \int\limits {5 e^{x} } \, d x

<em> By using integration formula</em>

                                       \int\limits { e^{x} } \, d x = e^{x} +C

                                     I =  \int\limits {5 e^{x} } \, d x  = 5 e^{x} +C

<em>where C is constant of integration</em>

the volumes of two similar figures are 729 mm and 2744 mm if the surface area of the larger figure is 392 mm what is the surface
Stolb23 [73]
We know that
[volume of larger figure]=[scale]³*[volume of smaller figure]
scale=∛(volume of larger figure/volume of smaller figure)
scale=∛(2744/729)-----> 1.56

[surface area of the larger figure]=scale²*[<span>surface area of the smaller figure]
</span>[surface area of the smaller figure]=[surface area of the larger figure]/scale²
[surface area of the smaller figure]=[392]/1.56²----> 162 mm²

the answer is
the surface area of the smaller figure is 162 mm²
