(2)の問いについてです。 定点となるMを右の写真の解のような形で表してはいけないのでしょうか。ダメな理由も教えていただけるとありがたいです

Check 例題 360 直線のベクトル方程式(1)円3 07*** (1) 異なる2点A(a),B() に対して, p=(1-t)+t6 (1) 表される図形はどのような図形か. (2) 3点A(a),B(b),C(c) を頂点とする △ABC がある. 辺ACを 21 に内分する点M () を通り,辺ABに平行な直線のベクトル 方程式をa, 6, こと媒介変数を用いて表せ 考え方 (1) ja+(-a) と変形すると,点P(j) は点Aを通り, ABに平行な直線上にあ ることがわかる (2)M(m)を通り、ABに平行な直線のベクトル方程式は,p=m+tAB と表せる。 解答 (1) = (1-1)+16=a+1(-a) 点P()は,点Aを通り b=a+1(6-9) 1 変化する 定点 A1=0 6-d=ABに平行な直線, すなわち直線AB上を動き, b-a a t=0 のとき, = より, 点Aの位置 t=1 のとき, = より,点Bの位置 t=1 B tが0から1まで変 わるとき、点Pは点 にある。 よって、求める図形は, 線分AB である. AからABの向き (2) 求める直線上の任意の点をP() とする.点M(㎡) に, Bまで動く。 a+2c は,辺ACを2:1 に内分する点だから, m= 3 求める直線は辺AB と平行だから,その方向ベクト ルは, AB (S-C A(a) よって,=m+tAB=+2c+(-a) P(p) (M(m) 3 すなわち, = (1/31) a1+1+1/2/30 B(b) c(c) AB JS Focus 点A(a)を通り, d に平行な直線のベクトル方程式は, p=a+td 2点A(a),B(b) を通る直線のベクトル方程式は, b=(1-t)a+tb とくに, t のとき, 線分AB を表す 足して1

英検準一級の要約問題です。 添削していただけないでしょうか?🙇‍♀️

英検公式サンプル問題 ⚫ Instructions: Read the article below and summarize it in your own words as far as possible in English. ⚫ Suggested length: 60-70 words Write your summary in the space provided on your answer sheet. Any writing outside the space will not be graded. From the 1980s to the early 2000s, many national museums in Britain were charging their visitors entrance fees. The newly elected government, however, was supportive of the arts. It introduced a landmark policy to provide financial aid to museums so that they would drop their entrance fees. As a result, entrance to many national museums, including the Natural History Museum, became free of charge. Supporters of the policy said that as it would widen access to national museums, it would have significant benefits. People, regardless of their education or income, would have the opportunity to experience the large collections of artworks in museums and learn about the country's cultural history. Although surveys indicated that visitors to national museums that became free increased by an average of 70 percent after the policy's introduction, critics claimed the policy was not completely successful. This increase, they say, mostly consisted of the same people visiting museums many times. Additionally, some independent museums with entrance fees said the policy negatively affected them. Their visitor numbers decreased because people were visiting national museums to avoid paying fees, causing the independent museums to struggle financially.
