A country's population in 1993 was 72 million. In 1996 it was 76 million. Estimate the population in 2003 using exponential grow
miss Akunina [59]
We use the formula for exponential growth:
P = Po exp(kt)
Using the population data from 1993 to 1996, we can solve for the growth rate k
76 = 72 exp(k(3))
76/72 = exp(3k)
ln (76/72) = 3k
k = ln(76/72) / 3 = 0.0180

In 10 years (2003), the population will be:
P = Po exp(0.0180t)
P = 72 exp(0.0180(10))
P = 86.22 million

An inner city revitalization zone is a rectangle that is twice as long as it is wide. The width of the region is growing at a ra
Ket [755]

Answer:

The area is changing at the point of  \mathbf{61200 m^2/year}

Step-by-step explanation:

From the given information:

Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w

where;

L = length and w = width of the rectangle

Suppose the Length L is twice the width w

Then L = 2w --- (1)

From The area of a rectangle

A = L  × w

A = 2w  × w

A = 2w²

Taking the above differentiating with respect to time

\dfrac{dA}{dt }= 4w \times  \dfrac{dw}{dt} --- (2)

At the time t

\dfrac{dw}{dt}= 34 m \ per \ year ; w = 450 \ m

Replacing the values back into equation 2, we get:

\dfrac{dA}{dt }= 4 \times 450 \times 34

\mathbf{\dfrac{dA}{dt }= 61200 m^2/year}

Evaluate f(x)=0.5^-2​
Ganezh [65]

Answer:

f=1/25x

f=4/5f (simplified)

x=1/25f

x=4/5x (simplified)

Step-by-step explanation:

To solve for f.

fx=5−2

Step 1: Divide both sides by x.

fx/x=1/25/x

f=1/25x

To solve for x

fx=5−2

Step 1: Divide both sides by f.

fx/f=1/25/f

x=1/25f
