Answer:

Rounding to two significant figures the number became

$8468=8\bar{5}00$

Step-by-step explanation:

Given : Number 8,468

To find : Round this number to two significant figure ?

Solution :

Rounding to two significant figure we have to estimate or round the values in terms of zeros.

Rounding the number to hundreds value,

As 6 is greater than 5 so 4 rounds to 5 and rest became zero.

i.e. $8468=8\bar{5}00$

bar means the estimated value.

Therefore, Rounding to two significant figures the number became

$8468=8\bar{5}00$

Brainly to whomever somehow solves for x. I WILL REPORT SCAMS AND UNHELPFUL "WHAT?" ANSWERS.

aivan3 [116]

Answer:

Step-by-step explanation:

I would have thought the answer would be whole numbers...

using top line....

5x-5y + 7x-15 = 180 (that is a line)

12x - 5y = 195

using bottom line

4x+ 4y +2x+ y = 180

6x + 5y =180

~~~~~~~~~~~~~~~~~~

12x - 5y = 195

6x + 5y =180

(fives cancel)

18x = 375

x = 20.83

y= 11

Is 3^100/3^99 greater than,less than, or equal to 3??

oksian1 [2.3K]

Answer:

$\frac{3^{100}}{3^{99}} = 3$

Step-by-step explanation:

$\frac{a^{m}}{a^{n}}=a^{m-n}, m>n\\\\$

Therefore,

$\frac{3^{100}}{3^{99}}=3^{100-99}=3^{1}=3\\\\\frac{3^{100}}{3^{99}} = 3$

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

attashe74 [19]

Answer:

$t=7.85 years$

Step-by-step explanation:

We can write this rate as an ordinary differential equation.

$\frac{dP}{dt}=aP$

Where a is proportional constant, P the population variable, and t the time.

$\frac{dP}{P}=adt$

Integrating each side of the equation.

$\int \frac{dP}{P}=\int adt$

$ln(P)=at+c$

$P=e^{at+c}$

$P=e^{c}e^{at}=Ce^{at}$

To find C we need to use the initial condiction, it means evaluae P at t=0.

$P_{0}=Ce^{0}=C$

$P=P_{0}e^{at}$

Now, we use the sentence the population has doubled in 5 years.

$2P_{0}=P_{0}e^{a5}$

We can find "a" in this condition.

$2=e^{a5}$

$ln(2)=a5$

$a=\frac{ln(2)}{5}$

$a=0.14$

Finally, let's find how long will it take to triple.

$3P_{0}=P_{0}e^{0.14t}$

$3=e^{0.14t}$

$t=\frac{ln(3)}{0.14}$

$t=7.85 years$

I hope it helps you!
