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

Why is adding 3/9 and 6/9 different from multpying the two fractions? Explain

<h3>♫ - - - - - - - - - - - - - - - ~<u>Hello There</u>!~ - - - - - - - - - - - - - - - ♫</h3>

➷ When you add fractions, you have to have the same denominator whereas, when you multiply them, you don't have to. (In this case the denominators are already the same.) Also, multiplying the fractions would make the result smaller whereas adding them would make it larger.

Stells [14]
He will need 527.52 cubic centimeters of wax. You divide the diameter by 2 ten multiply that number by itself to get the circumference. From there you multiply it by 12 then by 4 and there's your answer

Find the inverse of square root f(n) = n – 3.
pogonyaev

Answer:

f'(n) = n + 3

Step-by-step explanation:

Given

f(n) = n - 3

Required

The inverse

f(n) = n - 3

Replace f(n) with y

y = n - 3

Swap positions of y and n

n = y - 3

Make y the subject

y = n + 3

Replace y with f'(n)

f'(n) = n + 3
