Find the derivative. f(x) = e^(x) cosh(x)

zhenek [66]

We are given

$f(x)=e^{x} cosh(x)$

Since, $e^{x}$ and $cosh(x)$ are multiplied

so, we will use product rule of derivative

$\mathrm{Apply\:the\:Product\:Rule}:\quad \left(f\cdot g\right)'=f\:'\cdot g+f\cdot g'$

$f'(x)=\frac{d}{dx}\left(e^x\right)\cosh \left(x\right)+\frac{d}{dx}\left(\cosh \left(x\right)\right)e^x$

we know that

$\frac{d}{dx}\left(e^x\right)=e^x$

and

$\frac{d}{dx}\left(\cosh \left(x\right)\right)=\sinh \left(x\right)$

so, we can plug these values

and we get

$f'(x)=e^x\cosh \left(x\right)+\sinh \left(x\right)e^x$ ...............Answer

At school B, 108 year 8 students study French.

Masteriza [31]

Step-by-step explanation:

108 = 60%

1% = 60%/60 = 108/60 = 1.8

100% = 1%×100 = 1.8×100 = 180

how many do not study French ?

the remainder of the students. that is 40% (100% - 60%) or 72 students (40×1.8 or simply 180-108).

Sliva [168]

Total bill would be excluding the discount, so Deens has included the discount on the wrong side of the equation.

So: 9X = 88-25
9X=63
63/9=7
therefore Deens bought 7 shirts
