Please help!! If f (x) = e^x sin x, then f’ (x) =

shusha [124]

Answer:

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

Step-by-step explanation:

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

What is the partial fraction decomposition of<br> 7x squared- 6x +9/<br> 3x(4x squared +9)

Anit [1.1K]

9514 1404 393

Answer:

1/(3x) =(x -2)/(4x^2 +9)

Step-by-step explanation:

The denominator cannot be factored further, so the final form will be ...

A/(3x) + (Bx +C)/(4x^2 +9)

The value of this is ...

(A(4x^2 +9) +(3x)(Bx +C))/(3x(4x^2 +9))

= ((3B+4A)x^2 +3Cx +9A)/(3x(4x^2 +9))

Equating coefficients gives ...

3B+4A = 7

3C = -6 ⇒ C = -2

9A = 9 ⇒ A = 1

Using the found value of A, we find ...

3B +4 = 7 ⇒ B = 1

Then the decomposition is ...

$\dfrac{7x^2-6x+9}{3x(4x^2+9)}=\boxed{\dfrac{1}{3x}+\dfrac{x-2}{4x^2+9}}$

Deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?

slavikrds [6]

deion has the following data: 47, u, 41, 38. if the range is 10 which could "U" be ?

REmember that

The range of a set of data is the difference between the highest and lowest values in the set

If U is the highest value

Range=U-38

range=10

10=U-38

U=10+38

U=48

If U is the lowest value

Range=47-U

10=47-U

U=47-10

U=37

therefore

U coulbe between 48 and 37
