The area of a circular wave expands across a still pond such that its radius increases by 14 cm each second. Write a formula for
lara31 [8.8K]

Answer:

A = π(14t)²

Step-by-step explanation:

The radius is increasing at the rate of 14 cm per second.

We need to find the formula for the area A of the circle as the function of time t.

Initial area of the circle,

A = πr², where r is the radius of the circle

Area as a function of t will be :

A = π(14t)²

Here, 14t is the radius of the wave.

It has been estimated that the population of Indianapolis is growing at a rate of 0.9% per year. Assuming that population growth
Mumz [18]

Answer:

<em>2,136,605</em>

<em />

Step-by-step explanation:

To estimate growth, we use the formula shown below:

F=P(1+r)^t

Where

F is the future amount (we want to find for Jan 2024)

P is the present amount (present population of 1,988,817)

r is the rate of growth (0.9% means 0.009)

t is the time in years (from Jan 2016 to Jan 2024 is 8 years, t = 8)

<em>Let's put these into the formula and figure out F:</em>

<em>F=P(1+r)^t\\F=1,988,817(1+0.009)^8\\F=2,136,604.5</em>

<em />

<em>Rounding we get the population in Jan 2024 to be </em><em>2,136,605</em>
