The net profit in dollars per day for a small business owner is given by the equation f(x) = -0.1x^2 + 6 x + 4, where x is the n

notsponge [240]

Answer:

$\large \boxed{\sf \ \ \text{The maximum profit is \$94 per day.} \ \ }$

Step-by-step explanation:

Hello,

The coefficient in $x^2$ is negative.

So, there is a maximum at the vertex point which is

$x=-\dfrac{b}{2a}==\dfrac{-6}{-0.2}=\dfrac{6}{0.2}=30$

And then the maximum is f(30)=

$-0.1\cdot 30^2+6\cdot 30 +4=-90 +180+4=94$

So the maximum profit is 94 $ per day.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

If the m = and the b = -2. then the linear equation is:

Leto [7]

Hey there! I'm happy to help!

The linear equation with m and b is called the slope intercept equation, where m is the slope and b is the y intercept. It is written as y=mx+b.

We see that m is equal to 1 and b is equal to -2. We can write this down as y=1x-2, or just y=x-2 as 1x is just x.

Have a wonderful day! :D
