We use co-ordinates 4 maths & maps but why do we use negative (4 quadrents) in 'real life'?

you've got your four quadrants\n\n1st: x-y axis plus plus >>>>>> plus\n2nd; negative plus>>>>negative\n3rd; negative negative>>>plus\n4th; plus negative>>>negative\n\nfor trig;  all,sine,tan,cos\n\ni hope that this helps

In quadrant II, the x-coordinate is negative and the y-coordinate is positive.\nSo in which quadrant is the x-coordinate positive and the y-coordinate negative?  The fourth quadrant.\n\nCarla = z\nOdell = 3z\nKai = 3z - 8\nAdd everything together.\nz + 3z + 3z - 8 \n= 7z - 8  \n(B)

4.4.........the zeros cancel themselves otherwise the answer would be 8 but because of decimal point locations, its just 4.4.....\n\n\nhow did u come up with the answer?

in reality - null\nin math it allows us to put a placeholder between positive and negative numbers. It also allows a higher understanding of how math really works.

ehh its more a math term. in terms of math a conjugate would be something like if you had the given as: 3x-4, the conjugate would be: 3x+4. in essence it is the opposite as the original set of numbers. in conversation im not totally sure how you would use that and someone else may be of more knowledge there.. but ive only heard it in respects to math.

Are you able to use any other numbers and operators?  If so this would be fairly easy.  Using only Three 8's and a subtraction symbol it is not possibe\n\nClosest example (8+8)/8-1=1

Your fourth one is wrong.  Subtracting a negative integer is the same as adding a positive integer. So it is 4 + 8 = 12.\n\nSame rule for the fifth one.  -8 + 4 = -4.\n\nThe rest of them are correct.\n\nI am REALLY glad to see someone doing the work in this category, and just asking for verification help, instead of someone asking us to do all the work for them.  Good for you!

Polar\nits use to converse from dimensional to polar.\nexp\n(3,4) --> (5;53)\nits mean 5 for radius and 53degree

what it means is this 4 plus negative .01 and with the other it's 5 plus negative .04 its simple. if you know what it means and if you took notes look at them. it may help a little

Is that REALLY how you spell "please" in Spanish? I must have not heard it properly. The answer is A.\n\nSee:\n\nWhen we rotate a point of coordinates (a, b) a half turn about point (x, y), the image becomes (x - [a-x], y - [b-y]). In this case, that answer would be (1 - [-1 - 1], 2 - [3 - 2]), or (3,1).\n\nAdditional details:\n\nTake another example:\n\nIf we were to rotate point (4,1) about (5,8), this would give us (5 - [4 - 5], 8 - [1 - 8]), or (6, 15).\n\nCheck it. It's true!\n\nNOTE that this is only verification, not proof. If you want proof, go to that other guy.

It's eight. How I figured that out is I did 4x2, which is the same as 4+4 because there are two 4s being added in the equation. But since your mind is obviously far too inferior to even begin to comprehend such a subject, why don't I take your hand and walk you through it (not literally!!!), hm? First, we count to four. 1, 2, 3, 4. Then, we count four numbers starting at 5, because 4+1=5. So, 5, 6, 7, 8. 4x1+4x1 is another way to put it, but like I said, your mind is far too inferior to understand.

Do you require mathematical signs, or are standard operations OK (like square root)?\n\n1: (1 + 1 + 1)!\n2: 2 + 2 + 2\n3: 3 * 3 - 3\n4: sqrt(4) + sqrt(4) + sqrt(4)\n5: 5 + 5/5\n6: 6 + 6 - 6\n7: 7 - 7/7\n8: 8 - sqrt(sqrt(8 + 8))\n9: 9/sqrt(9) + sqrt(9)\n\nAnd for a bonus: (0! + 0! + 0!)! = 6

infact i am not clear about you question. even though i am trying to clear your doubt. ok\nyou can specify the geographical coordinations like the following exaple.\n\nfor example if you want to specify the end point of a line in 35°45'56.8" and the distance of 25 from the start point  you can enter\n@25<35d45' 56.8"\n\nnote: no space between @ to "\n\nfor degree use d\nfor minut use '\nfor second use "

The additive inverse is what you add to anything to get zero.  That means it's the negative!  Of course, the additive inverse of a negative (negative of negative) is positive.\n\ne.g. -4 + 4 = 0 and so each of 4 and -4 is the additive inverse of the other.

There may be infinite no of coordinates satisfying the condition x=y^2For example y=1.2.3.4.5.-1,-2,-3,-4,-5.......the values of x would be 1,4,9,16,25,1,4,9,16,25.........and so the coordinates of the points would be (1,1),(4,2),(9,3),(16,4),(25,5) and so on ...

im a geo student, but i havent done proofs for a long time sorry. ok\n2. false, because squares are parallelograms with 4 congruent sides and 4 right angles, while kites have 2 pairs of congruent sides and only 1 pair of congruent angles that are NOT right angles\n3. false, because a rhombus is a parallelogram with 4 congruent sides, while a kite is any thing BUT a parallelogram. enuff said\n4. false, because kites are quadrilaterals with only two pairs of congruent sides, while the quadrilateral mentioned has 3 congruent sides\n5. false, for example- do trapezoids have 4 congruent sides, and 4 right angles, and is a parallelogram (characteristic of squares)? i think NOT\n6. read above- trapezoids are not parallelograms.

They add up to 360 degrees. (If you walked around the quadrilateral you would end up facing the same way as when you started, hence you went through 360 degrees. For a re-entrant or crossed-over quadrilateral, make that 360k degrees)
