velikii [3]

Answer:

sec(x)tan(x)

Step-by-step explanation:

This is a direct application of the <em>fundamental theorem of calculus</em>, which tells you ...

$\displaystyle\frac{d}{dx}\int^x_a {f(t)} \, dt=f(x)$

Here, f(t) = sec(t)tan(t) and a=3. So, the derivative is ...

How do I find the maximum profit of -30x2+660x-1500

lina2011 [118]

Answer:

2,130

Step-by-step explanation:

1. solve for x.

$x=-\frac{b}{2a}$

when $ax^{2} +bx+c$

$x=\frac{-660)}{2(-30)}\\\\x=\frac{-660)}{-60}\\\\x=11$

2. place value for X into equation

$y=-30x^{2} +660x-1,500\\y=-30(11)^{2} +660(11)-1,500\\y=-30(121)+7,260-1,500\\y=-3,630+7,260-1,500\\y=3,630-1,500\\y=2,130$

Maximim profit is 2,130.
