Any time the car is driving, the amount of gas is decreasing.
The only time the amount of gas can increase is the short time when
the car is parked at the gas station and gas is being poured into it.

Amanda drover towards the shop, stopped and got gas, then
drove some more.  So the amount of gas decreases for a while,
then increases for a short time, then decreases again.

The middle graph is the one doing that.

If Kamila can do a job in 26 hours and Simon and Kamila working together can do the same job in 9 hours , find how long it takes
Kay [80]

Answer:

Simon takes approximately 13.76 hours to complete the job alone.

Step-by-step explanation:

We are given the following in the question:

Kamila can do a job in 26 hours  

So, part of work done by Kamila in 1 hour =

\dfrac{1}{26}

Simon and Kamila working together can do the same job in 9 hours .

So, (Simon and Kamila)'s 1 hour work =

\dfrac{1}{9}

So, Simon's 1 hour work =

\dfrac{1}{9}-\dfrac{1}{26}=\dfrac{17}{234}

So,

Simon can do \frac{17}{234} part of work in hour = 1

Time taken by Simon to complete the job alone =

\dfrac{1}{\frac{17}{234}}=\dfrac{234}{17}\approx 13.76 \text{ hours}

Thus, Simon takes approximately 13.76 hours to complete the job alone.

⦁ The population of the Tallahassee metropolitan area was 382,627 at the end of 2017 with a growth rate of 2.78%. Using the expo
a_sh-v [17]

Answer:

The exponential growth model for the population of the Tallahassee metropolitan area is y=382627(1.0278)^t.

Step-by-step explanation:

The exponential formula is

y=b(1+r)^t

Where b is initial population, r is growth rate, (1+r) is growth factor and t is time (in years) after the initial year.

The population of the Tallahassee metropolitan area was 382,627 at the end of 2017. The growth rate is 2.78%.

Here the initial year is 2017 and rate is 0.0278

y=382627(1+0.0278)^t

y=382627(1.0278)^t

Graph of the equation is shown below. The x-axis represents the number of years after 2017 and y-axis represents the total population.

Difference between 2025 and 2017 is 8 years. Put t=8

y=382627(1.0278)^8

y=382627(1.0278)^8

y=476479.828188\approx 476479

Therefore the projected population in 2025 is 476479.
