sorry, this part: then f '(x) = (2)(2)(cosx)(-sinx) should say: then f '(x) = 2x + (2)(2)(cosx)(-sinx)

Thanks for your reply! That makes much more sense now. I guess I should go and review my identities.

In the Deep Structure of Educational Reform Jim cummins present this model as a ways to reverse the history of academic failure experience by students from non-dominant group in general and student from involuntary group.

Jim Cummins' intervention model offers solution that could reverse the academic failure experienced by the Puerto Ricans students in American school which have existed for generations. Assess their history of integration in American society and their present social status in the U.S. How are these related? what solution could be offer to improve the Puerto Rican people and their children present and future situation such as their lack of academic achievement and social upward mobility in the U.S? can it be changed? How? Explain. In the article, Deep Structure of Educational Reform Jim cummins present this Intervention model as a ways to reverse the history of academic failure experience by students from non-dominant group in general and student from involuntary group.

Can you please give detailed explanation of the following poem? Albuquerque Graveyard It would be easier to bury our dead at the corner lot. No need to wake before sunrise, take three buses, walk two blocks, search at the rear of the cemetery, to come upon the familiar names with wilted flowers and patience. But now I am here again. After so many years of coming here, passing the sealed mausoleums, the pretentious brooks and springs, the white, sturdy limestone crosses, the pattern of the place is clear to me. I am going back to the Black limbo, an unwritten history of our own tensions. The dead lie here in a hierarchy of small defeats. I can almost see the leaders smile, ashamed now of standing at the head of those who lie tangled at the edge of the cemetery still ready to curse and rage as I do. Here, I stop by the imitative cross of one who stocked his parlor with pictures of Robeson, and would boom down the days, dreaming of Othello's robes. I say he never bothered me, and forgive his frightened singing. Here, I stop by the simple mound of a woman who taught me spelling on the sly, parsing my tongue to make me fit for her own dreams. I could go on all day, unhappily recognizing small heroes, discontent with finding them here, reproaches to my own failings. Uneasy, I search the names and simple mounds I call my own, abruptly drop my wilted flowers, and turn for home.

You need to re-word this question. It doesn't make sense

Our skin is the largest organ of our body. An increased blood flow to the skin allows the body to cool off more effectively. Our body temp is 98.6, warmer than the average air temp. Bringing a larger volume of blood closer to the surface of out body, along with sweating, helps keep the body from over heating. Digestion is not the body's main concern during increased activity, especially if it's "fight or flight". Therefore blood flow to the intestines decreases while respiration and pulse increase during activity, allowing better oxygenation of vital systems.

How the interpretation of the rights of the accused has changed since the September 11th attacks and how this relates to the concept of law as a living body?

I think so too!

LOL!!! Are you posting each of all your homework problem on here and hope people would answer all of them for you? Hahaha! I tell ya, you learn nothing from this way. But anyway... the slope of any line parallel to line 1 is the same as the slope of line 1. With that known, all you got to do now is calculate the slope using the two given coordinate (don't tell me you don't know how to do that...).

(2x+1)(x+1)

x = -76/-4

I forgot most of my maths, haha. It's something you need to be constantly practice by doing homeworks.

Hm... can you just put in any random # for x and then plug into the equations and use your calculator to calculate the answers, then compare to see if you come up with the same answers?

16/18 24/27 32/36 etc...

I'll have to go with parabola!!!

m/s^2 assuming g = gravity force in your case.

8400 + 8x = 12500 8x = 4100 x = $512.50 (amount of inflation per year) Note that you cannot convert this to percent rate because it wouldn't be steady. For the first year, 512.5/8400 = 6.1%. For the second year, the car is going to cost 8912.5, and 512.5/8912.5 = 5.75%. And so on...

Why don't you follow the direction and try that out? Then just connect the points and you'll see what you get. I think it's very self-explanatory.

Can't read your choices here... but isn't it (-infinity,+infinity)?

Price drops?

Huh? Lol. Calcium and ethanol? Ca --> CH3CH2OH???? ???

Not 100% sure, but I think 5 gallons. 20 gallons of 10% acid meaning 2 gallons of acid + 18 gallon of solvent (H2O/OH). To get it down to 8% acid, you need to dilute it to 25 gallons because you know you have 2 gallons of acid, and 2/25 - 8%. So to get 25 gallons as your final volume, you would add 5 more gallons of the 10% OH. Note that it doesn't really matter if it's 10% OH or 100% OH... and I'm assuming that the OH has no effect to the concentration of the acid (if it's base, then it would have an effect).

Huh? I am confused... the problem states that angle C is a right angle... so does that simply mean angle C = 90 degrees?

Given: d1 = 64 d2 = 11 t(total) = 2 s1 = ? s1 = s2 + 5 Ask yourself, what t really is? t(total) = d1/s1 + d2/s2 substituting s1 as s2 + 5: 2 = 64/(s2+5) + 11/(s2) Common denominator: multiply s(s+5)/s(s+5)and you eventually get: 2s^2 - 65s - 55 = 0 Same old quadratic formula: s2 = 33.325 mph s1 = s2 + 5 = 38.325 mph Plug the # back in the original equation... 2 = 2, checked!

(k(k-1))/2!*(1/k)^2 square 1/k and group into one single faction = (k(k-1))/(2!*(k)^2) the k on top and the k on bottom cancel = (k-1)/(2!*k) you can rewrite this as: = (1/2!)*((k-1)/k) now multiply the whole thing by (1/k)/(1/k) {note: this is legal because it is the same as multiplying a number by 1} = (1/2!)*((1/k)(k-1))/((1/k)*k) the bottom cancel out {1/k*k = 1} and just multiply the top out = (1/2!)*(1-(1/k)) rewrite as: = (1-(1/k))/2! Fun problem!

Do you know how to approach these problems? I suggest you look at the example problems on your textbook. This is a very simple one... I always start out with ( )( ) Then I find two numbers that when you multiply together will give you a 25. Ask yourself, what 2 numbers would that be? In this case, you only have 2 options: either 1 x 25 or 5 x 5... I know it from experience, 5 x 5 is going to be it... and there's a reason for this and you'll see why. So now I have (5c )(5c ) Then I think of two numbers that multiply together would gives me -81 AND the sum of the multiplication to the each of the two numbers that I picked(5 and 5), it would be 0. It has to be 0 because your equation doesn't have any "c" term (You only have a c^2 and a constant). So now ask yourself, what two # would fit that criteria? It's very obvious... the choice is 9 and -9 because 9*-9 = 81, and 9*5c=45c, -9*5c=-45c, and the sum of 45c + (-45c) = 0. So 9 and -9 works. and so now you get (5c+9)(5c-9)=0 You are done here, but if you want to go a step further, go ahead and solve for c by setting up the equation: (5c+9) = 0 and c = -9/5 (5c-9) = 0 and c = 9/5 so c = +/- 9/5. How you get it... I know it's confusing, I can't think of other ways to explain it. Practice more problems and you'll find it very easy to find the fitting numbers.

umm... "A" would not be the correct answer. Don't forget the 4. It is not a square root. 4sqrt(625) means what number, when raise to the power of 4, would equal to 625? Other word, x^4=625 and what's x?

#22 and #25 = correct #21 use the distance formula: d = square root of [(x2-x1)^2+(y2-y1)^2] where the coordinates are (x1,y1) and (x2,y2) For your problem d = 5.... now you plug all the numbers in that equation and solve for y2.

Um... 5ft*8ft=40ft^2?

add up all the like-terms... you get: 17N + 9 = 180 17N = 171 N is about 10. Then plug 10 in for N and solve for each length

Size 7 --> 22 in --> 56 cm Size 1 --> 22/7 in (3.14 in) --> 56/7 cm (8 cm) Thus: Size 6 3/4 --> 3.14 * 6 3/4 in --> 8 * 6 3/4 cm = about 21.2 in. --> 54 cm

That should be sin(pi times t) not whatever symbol is up there.. sorry

Nevermind I figured it out

You have to get the square roots out of the denominator by multipling the top and bottom by (for the first on) the SQRT15. And the second one by (5-SQRT3). Then you should be able to simplify. I hope that helps a little!

I don't understand what they are asking! If anyone could explain that, that would be a great help!

The greatest 2 digit = 99 The greatest 1 digit = 9 Thus: 99 x 9 = 891 = 3 digits? Too easy to be true huh? I'm not sure if there are other ways of doing this.

First marble = 5 out of 9 chances (5 reds, total of 9 marbles) Second marble = 4 out of 8 chances (4 reds, total of 8 marbles left) Probability = 5/9 x 1/2 = 5/18 = 27.78%

Assume that the heights of women are normally distributed with a mean of 63.9 inches and a standard deviation of 2.5 inches. The U.S. Army requires that the heights of women be between 58 and 80 inches. If 200 women want to enlist in the U.S. Army, how many would you expect to meet the height requirements?

x = 0.25x + 33 1/3 (0.25x) + 6.80 x = ?

Mathematically, you can set up the problem as follow: 232 Cal/1.5 Cup = x Cal/1 cup 1x = 232/1.5 x = 154.7 Cal Another way, this is a no brainer question given the choices below. With 1.5 cup, you know it has 232 Cal, so with only 1 cup, you know the answer should be less than 232 Cal. Look at all the options, only 154.7 Cal makes sense. So you literally shouldn't have to do any math to figure this one out.

All right, so now you know how to do the math for it. I think most teacher would still accept the other answer as long as you logically explain why your answer should be less than 232 and not 0.006. Good luck!

Thank you.

I want best deals. Do you know of any cell phone which offers good deals?

Hm... quite a complicate question. A less complicate way to do this is trial and error. You can make a table with "n" sides and the sum of the angles in degree for each polygon (ie. triangle (3 sides) = 180, 4 sides = 360, 5 sides = 540... and so on). And base on the values, you can find the matching pairs that fit the ratio criteria. But I guess that's what your teacher intend you to do. So let's try to figure this out mathematically: You can come up with a formula to calculate the sum of the angles from the small table you created above: Angle = 180n - 360. Now you know that the ratio of the angles is 4:1 and the sides is 3:1, and so you have another formula for the other polygon: 4(Angle) = (3n)180 - 360. Angle = 135n - 90 Now using substituion and plug it back into the first equation, you get: 135n - 90 = 180n - 360 270 = 45n n = 6 Now that you know that one polygon has 6 sides, the other one must have three time as many, thus 18 sides. Check the sum of the angles for each, and you should come up with a ratio of 1:4 on the angles for both polygons. Problem solved!

I meant: NOT what your teacher intend you to do. Sorry for mistype. :p

Is this really a college question? Seems too easy. Let x represent the base of the triangle (pole to spot where the wire is). Since you said that the height of the pole is 6 feet longer than the base of the pole to where the wired is anchored. Now 6+x. 27 is the hypotenuse. Use a^2+b^2=c^2 and plug in the numbersnumbers, 29-x=6+x, do the rest and the answer will be 11.5 for x. Now add to 6, which will be 17.5.

thank you Ms. Sue. I just couldn't really understand the question before, but now I see.

So far I have calculated for the moles of ch4 and o2, by the ideal gas law. I then used the molar ratio to find the moles of product from each individual reactant. I determined that the limiting reactant is CH4 (don't know if that's correct). From there would I just use the moles of products produced from the excess reactant to determine the pressure of co2 and h20? How do I find the third partial pressure?

Well since we want to find the time of fight we can say t =2Usin60°/g our initial velocity is 20m/s Then we substitute t= 2( 20)sin60° And sin60° is 0.866 2×20 = 40 so 40×0.866 = 34.6s So therefore t=34.6s
