Question
Global Defense Spending Global defense spending stood at $\$ 1.44$ trillion in 2009 and is projected to grow at the rate of $\$ 0.058$ trillion per year through 2018.a. Find a function $f(t)$ giving the projected global defense spending in year $t,$ where $t=0$ corresponds to 2009.Hint: The graph of $f$ lies on a straight line.b. What is the projected global defense spending in $2018 ?$
Step 1
Since the spending is growing at a constant rate, we can use a linear function to model this. The general form of a linear function is $f(t) = mt + b$, where $m$ is the slope (rate of change) and $b$ is the y-intercept (initial value). Show more…

National health expenditures are projected to grow at the rate of $$r(t)=0.0058 t+0.159 quad(0 leq t leq 13)$$ trillion dollars/year from 2002 through 2015. Here, $t=0$ corresponds to 2002 . The expenditure in 2002 was $$ 1.60$ trillion. a. Find a function $f$ giving the projected national health expenditures in year $t$ b. What does your model project the national health expenditure to be in $2015 ?$
According to a study conducted by Forrester Research, Inc., the amount of money spent by online shoppers in the United States is projected to be $$f(t)=105 e^{0.095 t} \quad(1 \leq t \leq 6)$$ billion dollars in year $t,$ where $t=1$ corresponds to $2011 .$ a. Find the projected spending in each of the years 2011 through 2016 by completing the following table: $$\begin{array}{cccccccc}\hline t & 0 & 1 & 2 & 3 & 4 & 5 & 6 \\\hline f(t) & & & & & & & \\\hline\end{array}$$ b. Use the information from part (a) to sketch the graph of $f$.
