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

We are given

Since, and are multiplied

so, we will use product rule of derivative

we know that

and

so, we can plug these values

and we get

...............Answer

the thermometer is precise but not accurate

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
