Jake says adding 0 to an addendum does not change a sum. Is he correct

siniylev [52]

Nothing changes if you don't add anything.

Example:

10+10=20
20+0=20

nothing changes.

Answer:

$P(t) = P(0)e^{0.0693t}$

Step-by-step explanation:

The population of a community is known to increase at a rate proportional to the number of people present at time t.

This means that the population growth is modeled by the following differential equation:

$\frac{dP(t)}{dt} = rP(t)$

Which has the following solution:

$P(t) = P(0)e^{rt}$

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate.

The population has doubled in 10 years

This means that $P(10) = 2P(0)$ . We use this to find r.

$P(t) = P(0)e^{rt}$

$2P(0) = P(0)e^{10r}$

$e^{10r} = 2$

$\ln{e^{10r}} = \ln{2}$

$10r = \ln{2}$

$r = \frac{\ln{2}}{10}$

$r = 0.0693$

So the equation that will estimate the population of the community in t years is:

$P(t) = P(0)e^{0.0693t}$

For a class trip, the teachers would like to have one adult for every ten students. There are 190 students on the trip. How many

coldgirl [10]

You can solve this problem with the following

$\frac{1}{10} = \frac{a}{190}$
$10a = 190$
$a = 19$

There should be 19 adults on the trip.

(-3 * 10 to the power of 4) * (2 * 10 to the power of -3)

gayaneshka [121]

-3*10= -30 to the 4th power is 810,000
10 to the -3 power is -1000 * 2 is -2000

810,000 * -2000 = -1,620,000,000

If point B is at 0, then what are the values of points A and C?

Sunny_sXe [5.5K]

Answer:

Since the line is not scaled, then how do we know for sure. But, we do know that point A is the opposite of point C. For example, if C = 150, then A = -150
