True or False. Explanations are required. ### Vector Perpendicularity and ParallelismIn this section, we will explore the relationships between vectors in different dimensional spaces, specifically focusing on perpendicularity and parallelism.#### (d) Perpendicular and Parallel Vectors in \(\mathbb{R}^2\)- **Statement:** Suppose \(\mathbf{a}, \mathbf{b}, \mathbf{c}\) are non-zero vectors in \(\mathbb{R}^2\), and \(\mathbf{a}\) is perpendicular to both \(\mathbf{b}\) and \(\mathbf{c}\). Then \(\mathbf{b}\) and \(\mathbf{c}\) are parallel.#### (e) Perpendicular and Parallel Vectors in \(\mathbb{R}^4\)- **Statement:** Suppose \(\mathbf{a}, \mathbf{b}, \mathbf{c}\) are non-zero vectors in \(\mathbb{R}^4\), and \(\mathbf{a}\) is perpendicular to both \(\mathbf{b}\) and \(\mathbf{c}\). Then \(\mathbf{b}\) and \(\mathbf{c}\) are parallel.

More then one of the statements are correct, so which of the others would also be correct?
Need this answer.Thank you
I want written justification along.
Answer 2 and 3 in the question. Please make sure the answers are correct. This question is in three parts. Given the premises: If the steak is well done, it’s overcooked. If the steak is overcooked, the fire alarm will go off. Either the batteries have been changed or the fire alarm will not go off. The batteries have only been changed if the ladder is in the room. The ladder is not in the room. Conclude that the steak is not well done. 2. These premises don’t make sense in the real world. Why? 3. How can you change the premises so that they make sense in the real world?
6. Fill in the blank with "all", "no", or “some" to make the following statements true. Note that "some" means one or more instances, but not all. • If your answer is "all", then give a brief explanation as to why. If your answer is "no", then give an example and a brief explanation as to why. • If your answer is "some", then give two specific examples that illustrate why your answer it not "all" or "no". Be sure to explain your two examples. An example must include either a graph or a specific function. (a) For (a, b). functions f, if f"(x) > 0 on the interval (a, b), then f'(x) < 0 on the interval (b) For functions f, if f(x) is a polynomial, then it is differentiable for all x. (c) For f(x) at exactly one point. functions f, the tangent line to f(x) at x = a will intersect the graph of In mathematics, we consider a statement to be false if we can find any examples where the statement is not true. We refer to these examples as counterexamples. Note that a counterexample is an example…
