Serjik [45]

We have that the  <em>exponential growth function</em>  and  population be in 2020 is mathematically given as

  • y=325000e^{0.002t}
  • y=469925

From the question we are told

  • The population of a city has been increasing by 2% annually. The sign shown is from the year 2000.
  • Write an exponential growth <em>function</em> that represents the population t years after 2000.
  • What will the population be in 2020? Round your <em>answer</em> to the nearest thousand. The popu<em>l</em>ation will be about:

<h3>Population</h3>

a)

Generally the equation for the standard form of exponential  <em>function</em> is mathematically given as

y=325000e^{0.002t}

b)

With T =20

Hence

y=325000e^{0.002(20)}

  • y=469925

How many people have a membership?​
Ymorist [56]

Answer:

38 people have a membership.

Step-by-step explanation:

That's because the bottom row shows how many years they've had the membership.

And the y axis shows how many people or the frequency of people having the membership for that amount of years.

So its a bar graph that shows you how many of the members have had the membership for a set amount of years.

So all you have to do is add up each column,

0-2 years = 6 people

2-4 years = 8 people

4-6 years = 10 people

6-8 years = 8 people

8-10 years = 6 people

6 + 8 + 10 + 8 + 6 = 38
