Answer:

f'(x) =  {e}^{x}(  \sin x + \cos x )

Step-by-step explanation:

f(x) =  {e}^{x}  \sin  x \\  \\ f'(x) = \sin x \frac{d}{dx}  {e}^{x}  + {e}^{x}  \frac{d}{dx}  \sin x \\  \\ f'(x) =  \sin x \: {e}^{x}   +{e}^{x}  \cos x \\  \\ f'(x) =  {e}^{x}(  \sin x + \cos x )

muminat

9514 1404 393

Answer:

  8.6 km

Step-by-step explanation:

The circumference of a circle is given in terms of its radius as ...

  C = 2πr

Then the radius can be found from the circumference using ...

  r = C/(2π)

Filling in the given values, we find the radius to be ...

  r = (54 km)/(2·2.14) = (54 km)/6.28 ≈ 8.59873 km

The radius is about 8.6 km.

What is the solution to the equation 2(x - 3) = 2x + 5
Genrish500 [490]
Hello there!

2(x - 3) = 2x + 5

Let's start by using the distributive property for the left side.

(2)(x) + (2)(-3) = 2x + 5

2x - 6 = 2x + 5

Then we need to add 6 to both sides

2x - 6 + 6 = 2x + 5 + 6

2x = 2x + 11

We need to transfer 2x on the left side, we gonna do that by subtracting 2x from both sides

2x - 2x = 2x + 11 - 2x

0 = 11

Thus,

There are no solutions.

I hope this helps!

Good luck with your career!

Given b(x) = [X+41, what is b(-10)?<br> – 10<br> -6<br> 6<br> 14
OLEGan [10]

Option C: 6 is the value of b(-10)

Explanation:

The given expression is b(x)=|x+4|

We need to determine the value of b(-10)

To find the value of b(-10), let us substitute x=-10 in the given expression.

Thus, substituting x=-10 in the expression, we have,

b(-10)=|-10+4|

Adding the terms, we get,

b(-10)=|-6|

Since, we know the absolute rule that |-a|=a and the simplified expression is of the form |-a| , let us apply the absolute rule in the simplified expression.

Thus, we have,

b(-10)=6

Thus, the value of b(-10) is 6.

Hence, Option C is the correct answer.
