Brainliest pls??

Answer:

The song fully played 225 times.

Step-by-step explanation:

Really? What a question.

Between 10:55 pm and 9:50 am, 13 hours and 5 minutes elapse.

For us to calculate how many times the song played, we need to convert them to the same units, i.e. seconds.

3 minutes and 29 seconds = 209 seconds

13 hours and 5 minutes = 47100 seconds

If 47100 seconds elapsed and the song was playing on repeat the whole time, we can calculate how many times it played by:

47100/209 = 225.36 (approximation to the nearest hundredth)

So, the song fully played 225 times.

The revenue each season from tickets at the theme part is represented by t(x) = 3x. The cost to pay the employees each season is

Triss [41]

Answer: The profit after 5 seasons is $239.94.

Step-by-step explanation:

Since we have given that

Revenue function is given by

$t(x)=3^x$

Cost function is given by

$r(x)=1.25^x$

So, We need to find the total profit:

As we know the formula for profit:

Profit = Revenue - Cost

$P(x)=t(x)-r(x)\\\\P(x)=3^x-1.25^x$

We need to evaluate the profit after five seasons:

$P(5)=3^5-1.25^5\\\\P(5)=\$239.94$

Hence, the profit after 5 seasons is $239.94.

VLD [36.1K]

Answer:

A) 63.36 years.

B) 100.42 years.

Step-by-step explanation:

We have been given that the population of the world was 7.1 billion in 2013, and the observed relative growth rate was 1.1% per year.

A) Since we know that population increases exponentially, therefore we will use our given information to form an exponential model for population increase and then we will solve for the time by which our population will be double.

$P(t)=7.1(1.011)^{t}$

$7.1 \times 2=7.1(1.011)^{t}$

$\frac{7.1 \times 2}{7.1} =(1.011)^{t}$

$2 =(1.011)^{t}$

Now let us solve for t using logarithm.

$ln(2) =ln (1.011)^{t}$

$ln(2) =t \cdot ln(1.011)$

$0.6931471805599453 =t \cdot 0.0109399400383344$

$t=\frac{0.6931471805599453}{0.0109399400383344}$

$t=63.3593217267282743049\approx 63.36$

Therefore, it will take 63.36 years the population to be double.

B) Now we will find the number of years it will take the population to be triple of its size.

$7.1 \times 3=7.1(1.011)^{t}$

$\frac{7.1 \times 3}{7.1} =(1.011)^{t}$

$3 =(1.011)^{t}$

Now let us solve for t using logarithm.

$ln(3) =ln (1.011)^{t}$

$ln(3) =t \cdot ln(1.011)$

$1.0986122886681097 =t \cdot 0.0109399400383344$

$t=\frac{1.0986122886681097}{0.0109399400383344}$

$t=100.4221490079915311298\approx 100.42$

Therefore, it will take 100.42 years the population to triple of its size.
