Home >All Categories > Science & Mathematics >Engineering >Open QuestionCheepa Jagga Cheepa Jagga Member since:April 21, 2011Total points:95 (Level 1)I want theoretical meaning, I have a confusion while reading Boylestad's Electric Circuit Theory Book. I just read two contradicting statements regarding bandwidth and selectivity. It would be great if you can explain. Thanks.Answer Question

Open Question: Is there a difference between saying f(a) is algebraic over F and saying a is algebraic over F?

Here is some more information if it helps to undertstand the circumstance.
let f(x) be a nonconstant element of F[x]
a belongs to some extension of F

If they are different can someone please explain to me how becasue they seem like the absolute same to me...

Thank you!

Open Question: Can anyone describe to me the difference between permutations and combinations for Algebra II?

Remember: the number of permutations of n objects selected r at a time is n!/(n-r)!. the order in which things are chosen is significant.
The number of combinations is less: it's n!/((n-r)!r!). The order in which things are chosen is not significant.

1) There are 6 floats, and 3 choices are to be made among them. The order of selection matters, because the prizes are not the same: if floats A, B, and C win prizes, it matters whether A gets first prize, or B gets it, or C gets it.
So, use the permutation formula. n = 6 and r = 3, so the number of ways is 6!/(6-3)! = 720/6 = 120.

2) The order of selection does not matter here, since Nate wants to do both activities without having them be in any particular order.
So, use the combination formula. n = 7 and r = 2, so the number of ways is 7!/((7-2)!2!) = 5040/(120·2) = 21.

3) The order of selection does not matter here, since Gregory just wants to get 3 different boxes; it does not matter which one he picks up first.
So, use the combination formula. n = 5 and r = 3, so the number of ways is 5!/((5-3)!3!) = 120/(2·6) = 10.

Open Question: What is the difference between cereal and grain?

Open Question: What is the difference between cereal and grain?

Cereals or cereal grains are one type of food grain. There's also pseudocereals, pulses, and oilseeds.

"Cereals, grains, or cereal grains are grasses (members of the monocot families Poaceae or Gramineae) cultivated for the edible components of their fruit seeds (botanically, a type of fruit called a caryopsis): the endosperm, germ, and bran."

"Pseudocereals are broadleaf plants (non-grasses) that are used in much the same way as cereals (true cereals are grasses). Their seed can be ground into flour and otherwise used as cereals. Examples of pseudocereals are amaranth, Love-lies-bleeding, red amaranth, Prince-of-Wales-feather; quinoa, and buckwheat.[1]"

"Pulses
Members of the (pea family). Pulses have higher protein than most other plant foods. They may also contain starch or oil. Most widely grown include:
soybean common bean chickpea lima bean runner bean pigeon pea lentil field pea or garden pea lupin"

"Oilseeds
Grains grown primarily for the extraction of their edible oil. Vegetable oils provide dietary energy and some essential fatty acids. They can be used as fuel or lubricants."
