Answer:

The answer is

Step-by-step explanation:

Given: f(x) = 3 + 2x - x²

To compute f(3 + h) substitute x = 3 + h.

Similarly, to compute f(h) simply substitute x = h.

We are asked to compute $ \frac{f(3 + h) - f(h)}{h} $

f(3 + h) = 3 + 2(3 + h) - {(3 + h)²}

           = 3 + 6 + 2h - {9 + 6h + h²}

           = 9 + 2h - 9 - 6h - h²

           = - 4h - h²

Now, f(h) = 3 + 2h - h²

f(3 + h) - f(h) = -4h - h² - 3 - 2h + h²

                    = -6h - 3

$ \therefore \frac{f(3 + h) - f(h)}{h} = \frac{-3(2h + 1)}{h} $ which is the required answer.

Estimate the rate at which the total personal income is rising in a metropolitan area. In 1999, the population of this area was
Natasha2012 [34]

Answer:

X=\$1.64*10^9

Step-by-step explanation:

From the question we are told that:

Population size P=918000

Rate of Population increase  \frac{dP}{dt}=9700

Average annual income I= \$34,549

Rate of annual income increase  \frac{dI}{dt}=\$1300

Generally the equation for Total Income is mathematically given by

X=P \frac{dI}{dt}+I \frac{dP}{dt}

X=918000*1400+(9200*30593)

X=\$1.64*10^9
