mm とする。 いものを1 ところ、 福9→ 文字式の利用 ■平成26年度問題 3 右の表は2から50までの偶数を順に並べたものである。 表の間に位置している 4. 6. 14. 16 や、 場 に位置し ている 16 18 26.28 のように.表 に位置している4 つの偶数において最も大きい数と2番目に小さい数の和の2 乗から、2番目に大きい数と最も小さい数の和の2乗をひいた 差は32でわりきれることの証明を, 文字を使って (証明) 32 #294 FEBA JE したがって, 4つの偶数において最も大きい数と2番目に小さい数の和の2乗から, 2番目に大きい数と最も小さい数の和の2乗をひいた差は, 32 でわりきれる。 調べたこと (3 0以上の整数より大きくn+1より小さい分数のうち. 分母が3で分子が自然数である 数の和について調べ, 表にした。 n=0のときは, 1/31 01/23 の2つの分数があるね。 n=0のとき 1/3+1/8-12-1 n=1のとき 1/3+1838-11/13- = n=2のとき 73+8=18-5 n=3のとき 1+1=232-7 =3 2 46 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48 50 の中に完成せよ。 表 nの値 0 和 2 3 1 3 5 7 1 調べたことと表から, 0以上の整数nより大きくn+1より小さい分数のうち、分母が3 で分子が自然数である数の和は奇数になると考え,次のように予想した。 数P 予想 10以上の整数 nより大きくn+1より小さい分数のうち、分母が3で 分子が自然数である数の和は. 2n+1になる。 予想がいつでも成り立つことを証明 ① のように証明した。 証明① 0以上の整数nより大きくn+1より小さい分数のうち、分母が3で 分子が自然数である数は, nを用いて 3n+1.3n+2 と表される。 これらの和は, 3n+13n52=6n53-2 -=2n+1 したがって, 0以上の整数nより大きくn+1より小さい分数のうち、 分母が3で分子が自然数である数の和は, 2n+1である。 前を参考にして, 0以上の整数より大きく〃 +1より小さい分数のうち、分母が5で分 子が自然数である数の和について考える。 分母が5のとき 整数nより大きくn+1より小さい分数は いくつあるのかな。 次の (1) は最も簡単な数で. (2) は指示にしたがって答えよ。 (1) n=1のとき、nより大きくn+1より小さい分数のうち、 分母が5で分子が自然数である数をすべて求めよ。 (1) (2) 0以上の整数nより大きくn+1より小さい分数のうち、分母が5で分子が自然数であ る数の和は、4n+2であることの証明 ② を完成せよ。 証明② 0 以上の整数nより大きくn+1より小さい分数のうち, 分母が5で分子が自然数 である数は, n を用いて したがって, 0以上の整数nより大きく n +1 より小さい分数のうち、分母が5で 分子が自然数である数の和は, 4n+2である。 数 P9 A26 3 最も小さい 2n + (4n -16² 1or²

Jane: Risa: Jane: Risa: Jane: Risa: Jane: Risa: Jane: Risa: I was woken up by the earthquake this morning, and couldn't go back to sleep after that. Nothing fell on the floor or was damaged, but definitely it was a big one! I was scared! Yeah, it woke me up, too. I haven't felt one like that in a while, but I think I was too used to those shakings. I went to sleep right after. Weren't you scared, Risa? Yes, but just a little. I think I'm afraid of a really big one, like the one in Tohoku in 2011, anyway. You know, you can't be just scared ( ) preparing for disasters, Jane. Do you know what to do in an earthquake? There are almost no earthquakes in your country, right? No, I haven't experienced one in the U.K. Can you tell me what to do? Sure. The first priority is your safety. Hide under a desk or table to protect your head. Stay there until the earthquake stops. Then be prepared to move to a safer place. I'm sure we'll do some simulations in the evacuation drill held at school next Monday. We'll learn there what's important to do during an earthquake. Wow! That sounds great. I'm looking ( 1) the drill now. Maybe we can get "Moriyama-ku Evacuation Map" after the drill. It shows you (in, where, should, you, a disaster, go ). Jane: Risa: Oh, I'm glad to know that. You should make an emergency kit, too. Our family has made one each and put them near their bed. I see. Can you tell me how I should make it? Well, I'll send you an email later then.

この問題の②イ③カなのですがどうしてこの答えになるのですか?

2 ① 43% 40% 3 31% 次の英文は, 南アメリカの先住民に伝わる, クリキンディ (Kurikindi) という名前のハチ ドリ hummingbird) の短い物語を題材に書かれたものです。 (①)~(③)に 最もよく当てはまる語を,それぞれ下のア~カから1つ選び, 記号で答えなさい。 <宮崎県改気 I'd like to introduce a short story of a hummingbird. A hummingbird is a very little bird. The little bird's name in this story is Kurikindi. Kurikindi lived in a forest. One day there was a * fire in the forest. The little bin stayed there and tried to *put out the fire. But all the other animals hurried to *escape. When they saw Kurikindi on the way, they asked Kurikindi, “Why are you doing that?" Kurikindi answered, “I'm only doing something I can do." After ( ① ) this short story, I thought about a few things. For example, did the hummingbird believe he could put out the fire? Why did all the other animals want to escape from the forest? Kurikindi did (②) so small that others thought his *actions meant (③). Many people often think like that. What do you think about Kurikindi? * fire (火事) put out (消す) escape (逃げる) action (行動) ア read イ something ウ reading I came オ excuse カ nothing 動物は いであ はクリ 3 Alt 文にな に bel 分詞と 多く とされ stops 停」と 意味が が競 を選 (要約) 私の 催され 私の女 国人 に駅に い 私は
