An animal reserve has 40000 elk if the population is increasing at a rate of 19% per year how long will it take for the populati
vekshin1

Answer:

Step-by-step explanation:

This is of the form

P(t)=a(b)^t

Where P(t) is the ending population, a is the original population, b is the growth rate, and t is time in years.  We have everything we need to solve for t.  

80000=40000(1.19)^t

Let me explain the growth rate quickly.  If the exponential function is a growth function, that means (in this particular situation) that we have 100% of the population and we are increasing it by 19%.  That makes the growth rate 119%, which in decimal form is 1.19.  

Begin by dividing both sides by 40000 to get

2=(1.19)^t

To get that t out of its current exponential position, take the natural log of both sides:

ln(2)=ln(1.19)^t

and the rules of logs say we can bring the exponent down out front:

ln(2) = t*ln(1.19)

Divide both sides by ln(1.19) to get t alone:

\frac{ln(2)}{ln(1.19)}=t

Doing that calculation on your calculator gives you that

t = 3.9846...

but rounding to the nearest tenth gives you that

t = 4.0 years

If cos=3/5, then tan=
Juliette [100K]
This is a 3-4-5 triangle.

Remember, 
SOH-CAH-TOA

S(ine) =  O(pposite)/H(ypotenuse)
C(osine) = A(djacent)/H(ypotenuse)
T(angent) = O(pposite)/A(djacent)

In Cosine, the adjacent = 3, and the Hypotenuse = 5

Hypotenuse is the longest side. 

3,4,5 is the triangle that fits inside, therefore, the Opposite is 4, and Adjacent is 3

T(angent) = O(pposite)/A(djacent)

Plug in the numbers

T = 4/3

tan = 4/3 is your answer

hope this helps

a pool tank fills 60 gallons of water in 1/5 of an hour. How many gallons of water can be filled up in 1 hour?
klasskru [66]
If it takes 1/5 hour to fill 60 gallons
than multiply the fraction by 5 to get a whole hour
and multiply the 60 gallons by 5 to get the amount of water created in that hour
60*5= 300 gallons of water in 1 hour
