The function f(x) = -(x+4)^2+5 is written in vertex form and shows that the vertex of the graph of f is located at (-4,5)
1 answer:
There is only one value for x that makes
Given the vertex form of the function expressed as:
If the function f(x) = 5
Subtract 5 from both sides
Hence there is only one value for x that makes

Using proportions, it is found that the life span of the person would be 14 years, 212 days and 22 hours shorter.
---------------------------
- 2 packs a day for 35 years is 40 cigarettes a day for 12775 days, as
.
- Thus, a total of 511000 cigarettes, as
.
- Assuming each cigarette costs 15 minutes of life, the person loses 7665000 minutes of life, as
- One year has 525600 minutes, thus the person loses 14 years of life, as
- Looking at the decimal part, the person loses 212 days of life, as
- Again looking at the decimal part, 22 hours, as
- Thus, the person loses 14 years, 212 days and 22 hours of life.
