A rabbit population doubles every 4 weeks.There are currently five rabbits in a restricted area. If t represents the time in wee
sertanlavr [38]
Doubling formula is this:

P(t)=P(2)^{\frac{t}{d}}
where P=initial number of rabbits
t=time
d=time it takes to doulbe

ok, so 4 weeks is the doubling time so that is 4*7=28 days

we wawnt time=98
and oroiginal number of rabbits is 5 so
P(98)=5(2)^{\frac{98}{28}}
P(98)=5(2)^{3.5}
P(98)=5(2^3)(\sqrt{2})
P(98)=5(8)\sqrt{2}
P(98)=40\sqrt{2}
so P(98)≈56.56
we can't have .56 rabbit so round down or up
about 56 or 57 rabbits in 98 days

Suppose a teacher finds that the
horsena [70]

Answer:

Scores = 8

Step-by-step explanation:

To solve variation problems, you make mild assumptions and analogies

Let's score be represented with S

Let's Absences be represented with A.

Therefore

S varies inversely as A

S ~ 1/A

S = K/A

The K represents a contant notation so that we can easily figure the variation problem.

When Absences were 2

Scores were 12

S = K/A

12 = K / 2

Cross Multiply.

K = 24.

It means that, S = 24 / A.

For a student with 3 absences, the score would be:

S = 24 / A

S = 24 / 3

S = 8

Math is fun!
