The solution to the problem is as follows:
We have 2+.8(2) + .8(.8(2)) + .8(.8(.8(2))) + ... =
2( .8^0 + .8^1 + .8^2 + .8^3 + ... ) =
2(.8^n -1) / (.8-1) . As n-->infinity, .8^n-->0 giving us
<span>2(-1)/(-.2) = 2(5) = 10 meters.
</span>
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
That would be 30C4 - combinations of 4 from 30.
= 30*29*28*27
---------------- = 27,405 Answer
4 * 3 * 2 * 1
The solution would be like
this for this specific problem:
Since the number of
charter schools is eight less than twice the number of alternative schools,
then it’s:
<span>2x - 8 </span><span>
<span>and then
<span>2x - 8 = 36 </span>
<span>2x = 44 </span>
x = 22 </span></span>
So
there are 22 Alternative Schools in
the county. I am hoping that this answer has satisfied your query
and it will be able to help you in your endeavor, and if you would like, feel
free to ask another question.
<span>You may deduce what it represents by analyzing the formula you just wrote.
Well, </span>the coefficient of linear expansion as the fractional change in length per degree of temperature change.
ΔL = c x L(initial) x ΔT
where c is the coefficient of linear expansion. You can rewrite the equation to give you c.
c = ΔL / [L(initial) x ΔT]
<span>Just substitute the variables and the answer will be
c = 0.000028. </span>
Now, what it represents.It may represent the extent to which the rod expands with temperature when compared to its original length.
Answer:
<em>1885.5 m^3 of water</em>
<em></em>
Step-by-step explanation:
I'll assume this is the complete question
<em>Lauren has an above-ground pool. To keep the pool's skimmer working well, the water level must be 4 inches from the top of the pool. When the pool is filled to this recommended level, approximately how many cubic feet of water will it contain? Use π = 3.14
</em>
<u><em>The pool forms</em></u><em> a cylinder with a radius of 12 feet and a height of 4.5 feet.</em>
<em></em>
height of pool = 4.5 ft
radius of pool
= 12 ft
height of water is 4 inches below pool top
<em>12 inches make 1 ft</em>
4 inches = 4/12 ft = 0.33 ft
Therefore, height of water = 4.5 - 0.33 = 4.17 ft
<em>volume of the water in this section of the cylinder will be equal to the volume of the cylinder formed</em>
volume of cylinder formed by the water = volume of water = π
h
volume = 3.14 x x 4.17 = <em>1885.5 m^3 of water</em>
