Answer:
3/4 x 3/4 =9/16... 0.75 x 0.75 = 0.5625
Step-by-step explanation:
Answer: option C
Step-by-step explanation:
You need to use the formula for calculate the area of a circle:
Where the radius of the circle is "r".
You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:
Where "d" is the diameter of the circle.
Then, the radius is:
Finally, substitute the radius into the formula. Then, the area of the circle is:
Hypotenuse²= (4x)²+ x²=16x²+x²=17x²
Hypotenuse=√(17x²)= x√17
To find perimeter, we need to add all sides
P=x+4x+ x√17 =5x+x√17 =x(5+√17)
Answer:
G = kX
Where:
G - Growth rate
X = the initial/current population of rabbit
k = is the constant of proportionality.
Step-by-step explanation:
As we are told in the question, the growth rate is proportional to the current population. This information gives us the initial value needed to solve to find the population of rabbits at any given time.
Other information given as needed for computation and we are not asked to do anything further.
<u>Analytically,</u>
If X = 100
And it triples in 2 years. That is, 3*X = 300. 2 years is 24 months.
This gives us the monthly growth rate = 300/24 = 12.5 => 12 to 13 rabbits per months.
Foxes kill 2 rabbits per month. This implies that 2*24 = 48 rabbits are killed by Foxes in 24 months.
By implication, the population of rabbits in 2 years will be
X (in 2 years) = 300 - 48 = 252 rabbits.
