Answer:
Step-by-step explanation:
A) 16.13 = 12(1.03)ⁿ
1.344 = (1.03)ⁿ
ln(1.344) = n(ln(1.03))
n = (ln(1.344)) / ln(1.03)
n = 10.0062...
so a domain of 0 ≤ n ≤ 10 is reasonable
B) y-intercept is the height of the plant on day 0 which would be 12 cm
C) f(3) = 12(1.03)³ = 13.11 cm
average rate of change = Δh/Δn = (16.13 - 13.11) / (10 - 3) = 3.02 / 7
= 0.43 cm/day or average growth per day

Answer:
Her current age is 8 years old.
Step-by-step explanation:
Current age: x
"In 10 years, a child’s age will be 6 years less than triple her current age."
In 10 years: <u>x + 10</u>
6 years less than triple: <em>3x - 6</em>
<u>x + 10</u> = <em>3x - 6</em>
<em>solve.</em>
<em>16 = 2x</em>
<em>x = 8</em>
