Answer:

81 million

Step-by-step explanation:

In one year there is 365 days, if you divide 365/4.5 the answer is 81.1. And every 4.5 days add 1 million people, then you multiply

81.1*1 000 000 = 81 100 000

approaching to the nearest million, 81 million of babies are added each year.

On​ Melissa's 6th​ birthday, she gets a ​$5000 CD that earns ​3% ​interest, compounded . If the CD matures on her 10th ​birthday
amid [387]

Answer:

$5,632.45

Step-by-step explanation:

Assuming it is compounded semiannually, A(t) = P(1 + (r/n))^(n*t)

A(4) = 5000*(1 + (0.03/2))^(2*4)

A(4) = 5,000*(1.015)^8

A(4) = 5,000*1.12649

A(4) = $5,632.45

Since 201020102010, the town of Fall River has been experiencing a growth in population. The relationship between the elapsed ti
barxatty [35]

Answer:

48,558

Step-by-step explanation:

The function which models the relationship between the elapsed time, t in years, since 2010 and the town's population, P(t), is given as:

P(t)=36800\cdot2^{^\dfrac{t}{25}}

Now, 2020-2010=10 Years

Therefore we are required to calculate the population of the town 10 years after.

To do this, we simply substitute t=10 in the function.

P(10)=36800\cdot2^{^\dfrac{10}{25}}}\\=48557.9\\\approx 48558

According to the model, the population in Fall River will be 48,558 in the Year 2020.
