The value of sports team decreases at a steady rate of 20% each year. What is the total percentage loss (to the nearest integer)

Let the width = w.
The length is 6 times the width, so the length is 6w.
The perimeter is 70.
P = 2L + 2W

70 = 2(6w) + 2(w)

70 = 12w + 4w

70 = 14w

5 = w

The width is 5.
The length is 6 times the width, so the length is 6 * 5 = 30

Area of rectangle = LW

A = 5 * 30 = 150

The city of Anvil is currently home to 21000 people, and the population has been growing at a continuous rate of 4% per year. Th
Yanka [14]

Answer:

They'll reach the same population in approximately 113.24 years.

Step-by-step explanation:

Since both population grows at an exponential rate, then their population over the years can be found as:

\text{population}(t) = \text{population}(0)*(1 + \frac{r}{100})^t

For the city of Anvil:

\text{population anvil}(t) = 21000*(1.04)^t

For the city of Brinker:

\text{population brinker}(t) = 7000*(1.05)^t

We need to find the value of "t" that satisfies:

\text{population brinker}(t) = \text{population anvil}(t)\\21000*(1.04)^t = 7000*(1.05)^t\\ln[21000*(1.04)^t] = ln[7000*(1.05)^t]\\ln(21000) + t*ln(1.04) = ln(7000) + t*ln(1.05)\\9.952 + t*0.039 = 8.8536 + t*0.0487\\t*0.0487 - t*0.039 = 9.952 - 8.8536\\t*0.0097 = 1.0984\\t = \frac{1.0984}{0.0097}\\t = 113.24

They'll reach the same population in approximately 113.24 years.
