Differentiating Exponential Functions In Exercise, find the derivative of the function. 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:

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

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

The derivative of the function is:

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

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

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

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

Find the difference in simplest form for 3/5-1/7

morpeh [17]

Answer: 0.457

multiply 3 by 7, and get 21

multiply 1 by 5, and get 5.

5 × 7 = 35.

fraction: 21/35 and 5/35

Subtract the numerators

21 − 5 = 16 = 16/35

Now we need to simplify the fraction that we have.

17 is larger than 16. So we're done reducing numbers.

Our final answer: $16/35$

Hope this helps!

I am joyous to assist anytime.

Answer:

1 : 2

Step-by-step explanation:

this is a 30-60-90 triangle which is a special right triangle. the ratio of the sides is x: x*sqrt(3): 2x, in the order short leg: long leg: hypotenuse. so the ratio of the short leg to the hypotenuse is x:2x or 1:2
