Answer:
$3425
Step-by-step explanation:
5% of $68500 is $3425
Area of rectangle prism, to find the answer, use this formula: 2 x ( h x d + h x w + d x w )
So it would look like this: 2 x ( 12 x 6 + 12 x 7 + 6 x 7 ) = 396
I would say the answer is B. 396 in2
Hope I helped ; )
Answer:
4th option
Step-by-step explanation:
x² - 2x - 3 = 0 ( add 3 to both sides )
x² - 2x = 3
using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 1)x + 1 = 3 + 1
(x - 1)² = 4
Answer:
Step-by-step explanation:
Let P be the population of the community
So the population of a community increase at a rate proportional to the number of people present at a time
That is
![\frac{dp}{dt} \propto p\\\\\frac{dp}{dt} =kp\\\\ [k \texttt {is constant}]\\\\\frac{dp}{dt} -kp =0](https://tex.z-dn.net/?f=%5Cfrac%7Bdp%7D%7Bdt%7D%20%5Cpropto%20p%5C%5C%5C%5C%5Cfrac%7Bdp%7D%7Bdt%7D%20%3Dkp%5C%5C%5C%5C%20%5Bk%20%5Ctexttt%20%7Bis%20constant%7D%5D%5C%5C%5C%5C%5Cfrac%7Bdp%7D%7Bdt%7D%20-kp%20%3D0)
Solve this equation we get

where p is the present population
p₀ is the initial population
If the initial population as doubled in 5 years
that is time t = 5 years
We get

Apply In on both side to get

Substitute
in
to get

Given that population of a community is 9000 at 3 years
substitute t = 3 in 

<h3>Therefore, the initial population is 5937.8</h3>
The answer is c because it is multiplying
