Answer:
Exponential growth function: P = 1700*e^(0.02*t)
After 10 years, the amount of population will be 2076
Step-by-step explanation:
Population growth is modeled by the following equation:
P = P0*e^(r*t)
where P is final population, P0 is initial population, r is rate of growth (as decimal) and t is time (in years)
Replacing with P0 = 1700, r = 0.02 and t = 10, we get:
P = 1700*e^(0.02*10) = 2076.38
The first one is a common multiple and I don't think I can see the rest of question two.
Answer: The height of the palm tree is 21 feet.
Step-by-step explanation:
We can use a ratio to solve this:
Actual height to shadow for both objects. The fraction equivalents must be equal.
6/8 = x/28 . Cross multiply
6(28) = 8x
168 = 8x Divide both sides by 8 (8's "cancel" on the right)
168/8 =8x/8
21 = x . This gives us the tree's height as 21 feet.
<em>Another way to solve this is to use the ratios, but simplify the first fraction</em>
<em>6/8 = 3/4</em>
<em>Then multiply the length of the shadow by 3/4</em>
<em>3/4 × 28 = height</em>
<em>28÷4 = 7 7 × 3 = 21</em>
<em>21 feet= the height of the palm tree.</em>
