ここの問題が全然わかりません…良かったら教えてください…😭

座標平面上において, 点を座標で表し、 図形を方程式で表すことを学んだ。 ここでは、このことを図形の性質の証明に利用することを考える。 考察 △ABC の辺BCの中点をMとすると 3-1 AB+ AC = 2 (AM2+BM2) 2) k² 2 が成り立つことを,どのようにしたら証明できるだろうか。 真さん: 辺 AB の長さを 2 点 A, B間の距離と 14 Leve 5 みて, 座標を利用して考えられないかな。 悠さん: 右のような三角形ABC に対して座標 軸をどのように設定したらよいのかな。 B M C 10 座標を利用して考えると,次のように証明できる。 点Mが原点,辺BCがx軸上になるよ y (ab) A(a,b) うに座標軸を設定すると, △ABCの頂 点 A, B, C の座標は, それぞれ A(a, b), B(-c, 0),C(c, 0) 0=(1+-+- 5 とおくことができる。 このとき # AB2 + AC2 DB(-c, 0) M(0,0) C(c, 0) = ={(a+c)+62}+{(a-c)+62} (a,d) = 2(a²+b²+c²) Ac 2(AM²+BM²) = 2 {(a² + b²)+c²} = 2(a²+b² + c²) したがって AB2 + AC2 = 2 (AM2+BM2) #問15 上の説明では, どのような工夫をして座標軸を設定しているか。 頂点 C の座標をA(a, b), B(c, d), C(e, f) とおいた場合の証明を想定 説明せよ。 図形の性質を証明するには、座標を用いて次のようにするとよい。 1 座標軸を適当に設定し、 図形の関係を数式で表す。 2 得られた数式を用いて計算する。 3 計算結果を図形的に解釈する。 1 賀

Lesson 3. Palliative Care 部突破! いま最もアツく、最もイカ Medical treatment / Health STEP P 1 Read the Article Let's learn about palliative care, medical care that relieves pain, symptoms and stress caused by serious illness. 1) Palliative care, form of health care that seeks to improve the quality of life of patients with terminal disease through the prevention and relief of suffering. It is facilitated by the early identification of life-threatening disease and by the treatment of pain and disease- associated problems, including those that are physical, psychological, social, or spiritual in nature. As defined, palliative care begins at the point of diagnosis of terminal disease and can be delivered in a variety of health care settings. In general, it involves health and social care professionals working in hospitals, communities, hospices, and voluntary sectors. 2) Palliative care has been associated with many different terms, including terminal care, care of the dying, end-of-life care, and supportive care. However, these forms of care are not necessarily the same as palliative care. Likewise, palliative care is also sometimes described as hospice care. While hospice care does imply palliative care, it is specific to care provided near the end of life. In contrast, palliative care covers the duration of a patient's illness and, hence, may be delivered over the course of years. 3) Palliative care emphasizes three main principles: 1) A team-based approach is fundamental in managing distressing symptoms, such as pain, nausea, fatigue, and depression. It is also a necessary component in meeting the physical and psychosocial needs of the patient and his or her family. 2) Dying is a normal process. Symptom management is needed in order to help patients live life to the fullest until they die. 3) The synthesis of physical care with psychological and spiritual care fulfills a vital role in the overall care of the patient. 4) Palliative care is a global concern, and a steady rise in the number of people who are living longer with degenerative disease suggests that demand for palliative care services will increase in the are areas of intense. developments such Standards Framewo and Palliative Care Indian Association health care profes intended to help physical and psyc 5) In some place For example, the and has identifie framework is int days of life.
