Question:
Suppose a plant has height 1.75 feet and it grows by 0.5 feet each month.
(A) Find the height after 7 months.
(B) Make a table of values for t varying from 0 to 10 months and show how the height, h, increases every month.
(C) Find an expression that relates h and t, and explain why it represents linear growth. [Page No. 25]
Answer:
Verified
(A) Height after 7 months = feet
(B) Table of values ( in months, in feet):
| (months) | (feet) |
|---|---|
| 0 | 1.75 |
| 1 | 2.25 |
| 2 | 2.75 |
| 3 | 3.25 |
| 4 | 3.75 |
| 5 | 4.25 |
| 6 | 4.75 |
| 7 | 5.25 |
| 8 | 5.75 |
| 9 | 6.25 |
| 10 | 6.75 |
(C) Expression of given problem is given by
It represents linear growth because increases by the fixed amount 0.5 ft for every unit increase in .
