Answer:

At most 2 adult haircuts

Step-by-step explanation:

The equation given is:

0.75C+1.25A \leq 70

This equation dictates the number of haircuts Horace gives in 7 hours.

Horace gave 5 child haircuts (C=5). So, that would make the equation:

0.75C+1.25A \leq 7\\0.75(5)+1.25A \leq 7\\3.75+1.25A \leq 7\\1.25A \leq 7 - 3.75\\1.25A \leq 3.25\\A \leq \frac{3.25}{1.25}\\A \leq 2.6

This means Horace can give LESS THAN or EQUAL to 2.6 haircuts.

2.6 haircuts doesn't make sense, so the maximum would be "2" haircuts.

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 )
