Solution :
Given initial population = 300
Final population after 1 day = 800
Number of days = 6
∴
P(0) = 300 P(1) = 300
We need to find P(8).
When P(0) = 300
∴ c = 300
∴
When P(1) = 800
∴ k = 750
So, P(8) is
= 11,614
So the population becomes 11,614 after 8 days.
By applying the Pythagorean Theorem and the Trigonometry ratio, CAH, the value of cos(M) = 4/5
<em><u>Recall:</u></em>
Trigonometry ratios, <em>SOH CAH TOA</em> can be applied to solve a right triangle.
- Pythagorean Theorem can also be applied which is: c² = b² + a², where c is the longest side (hypotenuse length).
<em><u>Given:</u></em>
ΔMNL is a right triangle
ML = 25
NL = 15
Find MN using the Pythagorean Theorem:
MN = √(ML² - NL²)
MN = √(25² - 15²)
MN = 20
To find the value of cos(M), apply the trigonometry ratio, CAH, which is:
cos ∅ = Adj/Hyp
- Where,
∅ = M (reference angle)
Hypotenuse = ML = 25
Adjacent = MN = 20
- Plug in the values:
cos(M) = 20/25
cos(M) = 4/5
