The town of madison has a population of 25,000. The population is increasing by a factor of 1.12 each year. Write a function tha
GaryK [48]
<h3>The population P(t) at the end of year t is   P(t)   = 25,000 \times (1.12)^t</h3>

Step-by-step explanation:

The initial population of town of Madison = 25,000

The rate at which the population is increasing = 1.12 times

So, the increase in population first year  :

( the initial population)  x (1.12)^1  = 1.12 x ( 25,000)  

= 28,000

So, the population at the end of first year = 28,000

Similarly, the increase in population second year  :

( the initial population)  x (1.12)²  =  ( 25,000)   x (1.12)²

= 31,360

So, the population at the end of second year =31,360

Now, to calculate the population in t years from now:

The population P(t) at the end of year t is

P(t)   = 25,000 \times (1.12)^t

36 boys complete a school task in 4 hours. How many boys would be required to complete the same task in 2¼ hours?​
vova2212 [387]

Answer:

20

Step-by-step explanation:

If 36 boys can conplete a task in 4 hours, then 19.35 boys could do it in 2 and a fourth hours.

You can set up an equation

A fourth of an hour is 15 minutes, so,

36 is to 4 as x is to 2.15, or,

36=4 as X=2.15

Multiply 2.15 by 36 (77.4)

77.4 divided by 4= 19.35.

Of course, you cannot have 19.35 boys, so there must be 20.

Hope this helps!

the water level in an ocean bay changes at a average rate of three meters per hour at this rate how many hours would it take for
Alik [6]
We know the rate of the change, 3 meters per hour. And we want to know how long it will take to reach 12 meters. Say we need to reach 6 meters instead 12.

How long will that take? 2 hours! Because we divide 6 m by 3 m/h.
Now let us do the same thing will 12 meters.

12 m / 3 m/h = 4 hours

It will take 4 hours to reach the 12 meters height.
