1. Problem 10a: Complete the table assuming linear growth.
Given points: $t=0$, $s(0)=24$ and $t=1$, $s(1)=186$.
2. Find the slope $m$ of the linear function $s(t) = mt + b$:
$$m = \frac{s(1) - s(0)}{1 - 0} = \frac{186 - 24}{1} = 162$$
3. Find $b$ (the y-intercept) using $s(0) = 24$:
$$s(0) = m \cdot 0 + b = b = 24$$
4. The linear model is:
$$s(t) = 162t + 24$$
5. Complete the table for $t=0,1,2,3,4$:
- $s(0) = 162 \times 0 + 24 = 24$
- $s(1) = 162 \times 1 + 24 = 186$
- $s(2) = 162 \times 2 + 24 = 324 + 24 = 348$
- $s(3) = 162 \times 3 + 24 = 486 + 24 = 510$
- $s(4) = 162 \times 4 + 24 = 648 + 24 = 672$
6. Problem 10b: Write the linear model:
$$s(t) = 162t + 24$$
7. Problem 10c: Complete the table assuming exponential growth.
Given $s(0) = 24$ and $s(1) = 186$, the exponential model is:
$$s(t) = a \cdot r^t$$
where $a = s(0) = 24$.
8. Find the growth rate $r$ using $s(1) = 186$:
$$186 = 24 \cdot r^1 \Rightarrow r = \frac{186}{24} = 7.75$$
9. The exponential model is:
$$s(t) = 24 \cdot 7.75^t$$
10. Complete the table for $t=0,1,2,3,4$:
- $s(0) = 24 \cdot 7.75^0 = 24$
- $s(1) = 24 \cdot 7.75^1 = 186$
- $s(2) = 24 \cdot 7.75^2 = 24 \cdot 60.0625 = 1441.5$
- $s(3) = 24 \cdot 7.75^3 = 24 \cdot 465.484 = 11171.6$
- $s(4) = 24 \cdot 7.75^4 = 24 \cdot 3608.0 = 86592$
11. Problem 10d: Write the exponential model:
$$s(t) = 24 \cdot 7.75^t$$
12. Problem 11: Given population model:
$$P(x) = 58000 (1.036)^x$$
where $x$ is years.
We want population after $m$ months.
Since $1$ year = $12$ months, convert months to years:
$$x = \frac{m}{12}$$
13. Substitute into $P(x)$:
$$P(m) = 58000 (1.036)^{\frac{m}{12}}$$
14. The correct choice is A:
$$P(m) = 58000 (1.036)^{\frac{m}{12}}$$
