shusha [124]

Answer:

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

Step-by-step explanation:

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

A line passes through the point (1, 5) and has a slope of -9.

vladimir1956 [14]

Answer:

y= -9x+14

Step-by-step explanation:

the equation of a straight line is y=mx+c

m is the slope

And we are given a y and x term

So we substitute these into the equation:

5= -9(1) + c

rearragne to find c

14= c

so the full equation is:

y= -9x+14
