A population of 100 frogs increases at an annual rate of 22%. How many frogs will there be in 5 years? Write an expression to re
gizmo_the_mogwai [7]
Exponential growth of the form:

F=Ar^t

F=100(1.22)^t

F(5)=100(1.22)^5

F(5)=270.27

F(5)=270 to the nearest frog...

....

1.22=r^12

r=1.22^(1/12)

F=100(1.22^(1/12)^t)

F=100(1.22^(t/12))  now it will produce monthly populations...

Say we did the same as before but instead of 5 years you have 60 months...

F(60)=100(1.22^(60/12))

F(60)=270 to the nearest frog... :P

3. Convert 150 yards per minute to feet per day.
vesna_86 [32]

One day has 24 hours.

One hour has 60 minutes.

One day has 24 x 60 = 1440 minutes.

1 yard is 3 feet.

150 yards x 3 = 450 feet.

150 yards per minute = 450 feet per minute.

450 x 1440 = 648,000 feet per day.

Davens pays $50 each week for guitar lessons. How much will he pay after 3/4 of a year
Alja [10]
You’ve got to work out 3/4 of the year first, that’s 75%, after you need to work out how many weeks are in those days so you divide it by 7 then divide that answer by $50 and hopefully you get your answer. hope this helps
