Differentiating Exponential Functions In Exercise, find the derivative of the function.<br> y = x2ex

I am Lyosha [343]

Answer:

$y' = xe^{x}(2 + x)$

Step-by-step explanation:

If we have a product function y, in the following format

$y = f(x)*g(x)$

This function has the following derivative

$y' = f'(x)*g(x) + g'(x)*f(x)$

In this problem, we have that:

$y = x^{2}e^{x}$

So

$f(x) = x^{2}, f'(x) = 2x, g(x) = e^{x}, g'(x) = e^{x}$

The derivative of the function is:

$y' = f'(x)*g(x) + g'(x)*f(x)$

$y' = 2xe^{x} + x^{2}e^{x}$

$y' = e^{x}(2x + x^{2})$

$y' = xe^{x}(2 + x)$

If there are 10 people in a race how many ways can 1st 2nd 3rd places be awarded

kiruha [24]

3 slots
1st slot has 10 possible people
2nd slot has 9 possible people (1 less than previous)
3rd slot has 8 possible people

so there are 10*9*8 ways or 720 ways

Lee is thinking of two Numbers,the product is 18. the quotient is 2

defon

X, y - the numbers

The product is 18.
$xy=18$

The quotient is 2.
$\frac{x}{y}=2 \ \ \ |\times y \\
x=2y$

Substitute 2y for x in the 1st equation:
$2y \times y=18 \\
2y^2=18 \ \ \ |\div 2 \\
y^2=9 \\
y=\pm \sqrt{9} \\
y=3 \ \lor \ y=-3 \\ \\
x=2y \\
x=2 \times 3 \ \lor \ x=2 \times (-3) \\
x=6 \ \lor \ x=-6 \\ \\
(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)$

The numbers are 6 and 3 or -6 and -3.
