-.06 is the answer
Answer:
f(t)=18,000(0.85)^t
Step-by-step explanation:
18,000 is the a value, and since it is depreciating 15% becomes -.15
so we are going to set it up like f(t)=18,000(1-0.15)^t
Final answer is f(t)=18,000(0.85)^t

Step-by-step explanation:
yo mama
One way to solve this would be to graph both y=x^2+6x+18 and y=2 - 1/x. If the graph of the polynomial is always higher up (above) the graph of y=2-1/x, that alone is sufficient cause to state that the poly is always greater than 2-1/x.
You could also do this algebraically: write the inequality
x^2+6x+18 > 2 -1/x. This can be rewritten as x^2+6x+18-2+1/x > 0, or
x^2+6x+16+1/x > 0
Try x=-3. Then 9-18+16-1/3 = 6 2/3, which is greater than 0.
Or you could graph x^2+6x+16+1/x by hand or on a calculator. Is the graph always above the x-axis? If so, <span>x²+6x+18 is always greater than 2-1/x.
