You see I need to know also the reproduction rate as well to equalize it. If 9% of the population declines each year from 2001 to 2021, around 21,006 would die by 2021. Which is 180% more than the population. If the reproduction rate isn't high enough to beat the declination rates, they'd be extinct by then.

Given: 315/1575. Write the prime fractorization of the numerator and the denominator, then write the fraction in lowest terms.
Ne4ueva [31]
The prime factorization of the numerator, 315, is 5 x 3 x 3 x 7. That of the denominator, 1575 is 5 x 5 x 3 x 3 x 7. To convert the fraction to its lowest form, cancel all the factors that appear to both the numerator and denominator. We will be left with 1/5.

Anyone know how to do 5c???? Please help!!!!!
nignag [31]

Answer:

71° F

Step-by-step explanation:

Consider the rational part of f(t)

\frac{40t^3}{t^3+100}  ( divide numerator and denominator by t³

= \frac{40}{1+\frac{100}{t^3} }

As t → infinity then \frac{100}{t^3} → 0 , the expression simplifies to

\frac{40}{1+0} = \frac{40}{1} = 40

Thus after driving for a long time

f(t) = 31 + 40 = 71° F
