Answer:
the 0
Step-by-step explanation:
Answer: 14 boys
Step-by-step explanation:
ratio 2:3
7 divided by 21 = 3, so 7 times 2 equals 14
Answer:
the play area is a circle with radius = 12
Step-by-step explanation:
Circle area = A= π r²
r = radius
A = 144 π = 452.39
Diameter = 2r
= 24
circumference = C = 2π r
= 24 π = 75.4
Q2)
Area = π r²
r = 15
r²= 225
area = 706.5
The population model is an exponential decay because it decreases
The exponential model of the population is P = 3000(0.64^1/7)^t
<h3>How to determine the function?</h3>
The population decreases by 0.36 every 7 years.
This means that the function is an exponential decay.
An exponential decay function is represented as:
P = a((1 - r)^1/n)^t
Where:
- a represents the initial value (3000)
- r represents the rate (0.36)
- n represents the number of years the population decreases (7)
- P and t are the variables
So, we have:
P = 3000((1 - 0.36)^1/7)^t
Evaluate the difference
P = 3000(0.64^1/7)^t
Hence, the exponential model of the population is P = 3000(0.64^1/7)^t
