Open Question: Expand and simplify the given polynomials?
x(x^2+x+3) - 3(x^2+x+3)
so then it is more simple
x(x^2+x+3) - 3(x^2+x+3)
= x^3 + x^2 + 3x - 3x^2 -3x - 9
Then group like terms:
x^3 + x^2 + 3x - 3x^2 -3x - 9
= x^3 + (1-3)x^2 + (3-3)x - 9
= x^3 - 2x^2 +0x - 9
= x^3 - 2x^2 - 9
And you're done!
Open Question: area of a rectangular swimming pool is given by . One side length of the pool is given by 3x^2+11x+6ft^2 One s?
iola Member since:April 17, 2011Total points:38 (Level 1)One side length of the pool is given by 3x + 2 feet. What is an algebraic expression for the other side length of the pool? Simplify this, and include correct units as part of your answer.Answer QuestionBe the first to answer this question.
Open Question: A voltaic cell consists of Mn/Mn2+ and Pb/Pb2+ half cells. Calculate the concentration of Pb2+ given......?
Please help. I believe you use the equation Ecell = standard-Ecell - ( 0.0592V / n) (log Q), but I cannot get the right answer.
Open Question: Calculus: Find an equation of the tangent line to the curve at the given point?
Since the point is (0,1) the slope at that point is f '(0) = 20(1)? = 20
So using the point-slope form of the line
y – 1 = 20(x – 0) or y = 20x + 1

Open Question: Find the volume of the solid obtained by rotating the region bounded by the given curves about the x-axis?
So we integrate from x = -2 to x = 2
On this interval, line is above the curve
Each cross section perpendicular to x-axis is shaped like a washer, with
outer radius: R = 4
inner radius: r = x²
We user washer method:
V = p ??2² (R² - r²) dx
V = p ??2² (16 - x4) dx
V = p (16x - x5/5) |?2²
V = p ((32 - 32/5) - (-32 + 32/5))
V = p (64 - 64/5)
V = 256p/5

Open Question: How the hell do you calculate speed when your only given HEIGHT?
Newton
d = 0.5at^2
30m = 0.5 * 9.8 m/s^2 * t^2
4.9 t^2 = 30
t^2 = 6.122
t = 2.47 s
v= at = 9.8 m/s^2 * 2.47 s = 24.25 m/s
Energy
PE = KE
MGH = 0.5MV^2 (cancel M)
GH = 0.5V^2
9.8 * 30 = 0.5 V^2
294 = 0.5V^2
V^2 = 294/.5 = 588
V = 24.25 m/s
No matter how you do it, the answer is always the same. (It would be really bad if it was not!)
Open Question: Given the levels of radiation in Japan's seawater, should we be concerned about fish and seafood globally?
Seafood from elsewhere will have harmless levels of radiation. The half life of the radiation is rather short, and will decay to nothing by the time it reaches other fishing waters

Open Question: find the slope of the line containing each given pair of points: (−1,4) and (5,−8?
(-1,4) = (X1, Y1)
(5,-8) = (X2, Y2)

(4 + 8)/-6
12/-6
-2
slope = -2

Open Question: Can I buy prenatal pills or must they be given over the counter !?
Sabre Member since:March 09, 2011Total points:73 (Level 1)Can I buy prenatal pills from like CVS or something ? Are they the same exact pills I would get prescribed from the doctor ? And when should I start taking them when I find out I'm pregnant??Answer Question
by Rosie908 Member since:May 11, 2009Total points:116 (Level 1)Yes you can buy them at CVS, Walgreens, and any pharmacy. Look for them on the iron and vitamin aisle or in the baby supply aisle. Take the prenatal pills as soon as you find out you're pregnant. Make sure to read the directions on the bottle to see how many times a day you should take them, and consult your doctor.
