Find the Derivative y’ implicitly.

Brums [2.3K]

$e^{x^2y} - e^y = e^y(e^{x^2} - 1) = x$

We should ISOLATE x

$e^y= \frac{x}{e^{x^2} - 1}$

Find the Natural Log of Both Sides to Make the Left Side "y"

$y = ln(\frac{x}{e^{x^2}-1})$

Now, FIND THE DERIVATIVE Using Chain Rule!!!

$y' = \frac{1}{\frac{x}{e^{x^2}-1}} * \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)^2}= {\frac{e^{x^2}-1}{x}}* \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)^2} = {\frac{1}{x}}* \frac{(1(e^{x^2}-1) - x(2x*e^{x^2})}{(e^{x^2}-1)} = {\frac{1}{x}}* \frac{(e^{x^2}-1 - 2x^2e^{x^2})}{(e^{x^2}-1)}$

Team one had 4 times less people than team two. After 6 people quit team two and 12 people were transferred from team two to tea

Snowcat [4.5K]

Answer:

There were 10 people in team one.

Step-by-step explanation:

Let x= team one.

Let y= team two

Because there four times less people in team one than in two we know that x=(1/4)y

After 6 people quit and 12 people transfer from team two, the two teams become equal. Therefore, x + 12 = y - 6 - 12.

You can then insert the initial equation for x into the second equation and know that there were 10 people in team one and 40 people in team two.
