8,16,24,32,40,48,56,64,72,80,88,96,104,112,120,128,136,144,152,160,168,176,184,192,200,208,216,224,232,240,248,256,264,272,280,288,296,304,312,320,328,336,344,352,360,368,376,384,392 and so on are all multiples of 8 because 8 times a number=those two multiplied is one of those answers. Hope this helps.
Answer: -1 so -1x
Step-by-step explanation:
You use the y1-y2/x1-x2 formula. so 9-7 is 2 and 5-7 is -2 you you have 2/-2 that simplifes to be -1
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 formula to find the area of a circle is 2 x r^2
so 2 x 13^2 = 338
