Calculate y' using chain rule. y = (e ^ (1 / x))/(x ^ 2)

Mathematics
1 answer:
Keith_Richards [23]3 years ago
7 0

Answer:

The answer is y^{'} =e^{\frac{1}{x} } (2x-1)

Step-by-step explanation:

First of all, we have product of 2 functions e^{1/x} and x^{2}

y^{'} =u\frac{dv}{dx}+v\frac{du}{dx}

Let u=e^{1/x} and v=x^{2}

using chain rule for u, \frac{du}{dx}=-\frac{1}{x^2}

and \frac{dv}{dx}=2x

Therefore,

y^{'} =u\frac{dv}{dx}+v\frac{du}{dx}=e^{1/x}(2x)+x^{2} (-\frac{1}{x^2})=e^{1/x}(2x-1)

Galina-37 [17]
Let p= the price of a ticket
Let c= the cost to put on the show

Formula:
(profit) = (ticket price) * (number of people) - (cost to put on show)
We have two equations here:
500=120p-c
400=100p-c
Solve:
100=20p
⇒p=5
⇒400=100(5)-c
⇒400=500-c
⇒c=100

So the price of a ticket is $5, and the cost to put on the show is $100.

HELP PLEASE 40 POINTS The graph shows the prices of different numbers of bushels of corn at a store in the current year. The tab
Vesna [10]

Answer:

see below

Step-by-step explanation:

Part A

Since the lines goes through the point (0,0) the graph is proportional. We can find the rate of change by take the price of corn and dividing by the number of bushels

24/3 = 8 dollars/ bushel

Part B

Previous Year Number of Bushels Price of Corn (dollars)

                                                  3 21

                                                 6 42

                                                  9 63

                                                 12 84

We can find the rate of change for the previous year by using the slope formula

m = (y2-y1)/(x2-x1)

m = (84-63)/(12-9)

    =21 / 3  

    = 7

The previous year was 7 dollars per bushel

The increase was 8-7 = 1 dollar per bushel
