The fox population in a certain region has an annual growth rate of 4 percent per year. It is estimated that
Minchanka [31]

Answer:

(a) P(t) = 12100*(1.04^t)

(b) in 2008, estimate of population is 16560 (to the nearest integer)

Step-by-step explanation:

Population in 2000, P(0) = 12100

Growth rate = 4% each year

(a) function model for the t year after 2000 (exponential model)

P(t) = 12100*(1.04^t)

(b) for 2008,

P(2008-2000)

= P(8)

= 12100*(1.04^8)

= 12100 * 1.368569

= 16559.7

= 16560  (nearest integer)

Find the slope of the line that passes through (4,2) and (4,5)
Hunter-Best [27]

Answer: Undefined

Step-by-step explanation:

(slope = m)

m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-2}{4-4}=\frac{3}{0}

(3 divided by 0 is undefined, so the slope is undefined)

What is the Area of the circle in pi units if the diameter is 6 cm?
sergejj [24]

The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.

<h3>What is the area of the circle?</h3>

The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,

A=\pi\dfrac{d^2}{4}

Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.

d=6

Put this value in the above formula to find the area of the circle as,

A=\pi\dfrac{6^2}{4}\\A=\pi\dfrac{36}{4}\\A=\pi\times9\\A=9\pi\rm\; cm

Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
