Exploring coordinate notation

I'm considering coordinate notation for points like A(5; -2; 4) and B(0,3; -1; -2). The entry for B seems to suggest a decimal coordinate with the "0,3" indicating two components. I think I need to confirm punctuation, especially for B's coordinate format. The length AB could be calculated next.

Then, for point C, if A and B are in 2D, C would just need x and y, not z. I need to check if the assignment asks for vector coordinates and a midpoint.Interpreting coordinates and notation

I'm looking at the A(3; -1, 5) notation, and it seems like it could represent a couple of coordinates. If it’s a three-coordinate format, it should be A(3; -1; 5). The semicolon between -1 and 5 looks like it might be a comma, so I’ll need to compare characters. The A before -2 and after 4 shows a clear semicolon. Given the context, it appears to be 3D, but the question seems to imply there are two subproblems. I should clarify my reading.Calculating distance between points

I think the first step is determining the separator in the coordinates; it looks like a semicolon. I’m assuming there are three coordinates, so for A and B, I’ll work that through. A becomes (5, -2, 4) and B looks like it might be (0.3, -1, -2).

So then I calculate the distance \(|AB|\) with the differences. It seems I might end up with a tidy result if I choose B as (0, 3, -1), making it more straightforward.Analyzing coordinates and notation

I’m trying to understand some coordinates here. I have A at (5, -2, 4) and B is likely (0, 3, -1). The differences seem to make sense. I’m wondering if that -2 I see at the end is part of the coordinates or if it belongs to another element. The notation in the image shows B as B(0;3;-1) and that extra -2 might simply be a parenthesis. Not quite sure about how it’s all displayed!Interpreting coordinates and dimensions

I see that after -1, there's a semicolon and then a -2. I'm not sure about B’s coordinates. Could it be possible that B is (0; 3; -1; -2), suggesting some 4D points? But if A is just (5; -2; 4), then I’m missing that fourth coordinate. It’s starting to look like B is probably (0; 3; -1) for a valid 3D point. Perhaps the notation details whether we're dealing with decimals! It’s quite a puzzle to piece together.Analyzing 3D and 2D Points

I’m considering two dimensions: the first being 3D points with decimals and the second being 2D points with decimals. There’s possibly a reference to a mathematical discussion on "Distance between points in space" and "Coordinates of the midpoint." Typical examples include points like A(5; -2; 4) and B(0; 3; -2). I need to parse how differences in coordinates lead to distance, and ensure I'm interpreting them correctly. I think I've nailed it; I’ll clarify the coordinates of B further.Clarifying Point B Coordinates

I’m inspecting the line for point B and noticing that after the 3, there seems to be a semicolon, followed by -2. The -1 I thought I saw might actually be just a separator artifact. When I magnify the reasoning, it looks like B might actually be \( B(0; 3; -2) \), not \( B(0; 3; -1; -2) \). In handwritten notation, a semicolon could resemble a comma, which makes sense. So, I believe B should just have one negative number, -2.Analyzing visual coordinates

I’m considering using visual coordinates from the displayed image in the prompt. At line B, I notice B(0,3 -1; -2). Hmm, the character after 3 seems like it has a long stroke and a dot, suggesting it could read as B(0; 3; -1; -2) with four entries. I wonder if it's not point B, but rather a vector in 4D.

Maybe the first line is A(5; -2; 4), and the second is B(0,3; -1; -2), which feels scientifically valid.Exploring coordinate exercises

I'm thinking there might be two separate exercises from a test that use the coordinates \(A(5; -2; 4)\) and \(B(0; 3; -1)\). I want to check my memory of common Russian textbook tasks in analytic geometry. I recall a task about finding the distance between points A and B, followed by another question about finding point C, the midpoint of segment AB.

It seems the handwritten B is likely \(B(0; 3; -1)\), and the trailing -2 could belong to A's second coordinate. So, it looks like the numbers were chosen to yield a nice result.Calculating midpoint and distance

Is it okay to address the stated reading? Maybe not necessary. I’ll solve for the second midpoint: Given points A=(3,-1,5) and B=(-2,4,3), I calculate the midpoint coordinates as: x = (3 + -2)/2 = 0.5, y = (-1 + 4)/2 = 1.5, and z = (5 + 3)/2 = 4. This gives midpoint C=(0.5, 1.5, 4). If A is (3, -1, 5) and B=(-2, 4, 3), then C=(0.5, 1.5) as the midpoint in 3D. The distance under B changes things.Calculating distance in space

I'm figuring out the formula for distance between two points in space. The formula is \( AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2+(z_B-z_A)^2} \).

I'm substituting values carefully, checking my decimal notation. After calculating, I find \( AB \approx 7.69 \).

If the question asks for coordinates of \( \vec{AB} \), I would say \( \vec{AB}=(-4.7;1;-6) \) and I could include "вектор" in a note to clarify.Rethinking coordinate strings

I’m considering the B string not as a single point but more like a line, specifically B(0; 3; -1; -2). The A string could be A(5; -2; 4), but it seems A only has three components. Maybe the first line should indeed be A(5; -2; 4), while questioning whether the B coordinates represent a vector. Ugh, I might not be on the right track here—let’s clarify things a bit!Evaluating decimal notation

I’m considering how the writer uses commas in numbers, which might indicate decimal notation. A’s coordinates could look like A=(3; -1.5; ???) with the third missing. But maybe A actually reads as A(3; -1; 5) if semicolons are mistaken for commas. Then, for B, it could be (0;3;-2), which makes sense as an integer in 3D space. I think I might have misread something, though, interpreting a semicolon as a negative sign. Let's clarify that!Considering dimensional coordinates

I'm wondering if B could actually be (0;3;-1; -2) instead, which would introduce a fourth coordinate. If A is (5;-2;4), that gives it three values. The question might not focus on distance but rather the line AB in 4D space. This concept could go beyond standard school definitions, but I need to be cautious. It's tricky since I really can't assume without more context or specific conditions laid out.Analyzing coordinates and notation

I'm considering the format for coordinates in the problem. It seems that in A(3; -1; 5), the semicolon after -1 could be misinterpreted. I notice that if we have B(0; 3; -1; -2), it might make sense as two separate entries. Looking at the provided image, it shows that the coordinates are indeed listed. So, I need to confirm the first point as A(5; -2; 4), ensuring clarity without adding unnecessary information.Inspecting integer interpretation

I'm considering using the standard integer interpretation and taking another look at the visual representation. In the image, I see B( 0 3 -1 ; -2 ) on line B, which is clearly displaying decimal values. So, my answer seems likely correct. The second A appears as A(3; -1,5), but I'm wondering if the mark after 1 is a semicolon, indicating three coordinates. It seems my notation for the first point could be B(0{,}3;\,-1;\,-2) and the second as A(3;\,-1;\,5), maybe even \(A(5;-2;4)\).
