23 15m 20 min. 362 words 次の英文を読んで、設問に答えなさい。 (1) A lot of people think cancer is the number one killer in the United States, but it's not. The leading killer is heart disease. Cancer is number two. Heart disease is responsible for about one-quarter of the deaths in the U.S. each year. Heart attacks (2a) account for over 500,000 deaths a year. One 5 reason the number of deaths from heart attacks is so high is that when people experience chest pain, they don't realize they may be having a heart attack and wait too long before going to the hospital. Such a delay can be fatal. (3a)- In fact, more than half of all heart attack victims die before they reach the hospital. 10 What are the warning signs of a heart attack? According to the American Heart Association, the signs include uncomfortable pressure or pain in the middle of the chest for two minutes or longer; movement of pain to the shoulder, arm, neck, or jaw; sweating may accompany the pain; *nausea and vomiting may 15 also occur; and shortness of breath, dizziness, or fainting may be experienced with the other signs. (3b) One of the factors that increase the risk of heart attack is high blood pressure. Today, with the stresses of everyday life, nearly one out of every three adults suffers from high blood 20 pressure. High blood pressure can be brought on by a fight with one's *spouse, problems at work, (2b) speaking in public, or even telling a lie. But it can also be brought on by something you enjoy, like the caffeine in a cup of coffee, cigarettes, or alcohol. There are, fortunately, ways to lower blood pressure - ways 25 Introduce

三次方程式の実数解の個数の問題です。 なぜx=±aがa≠0に繋がるのか分かりません、、、

日本 228 3次方程式の実数解の個数 (2) ①①①① 方程式x3ax+4a= 0 が異なる3個の実数解をもつとき, 定数αの値の を求めよ。 t 方程式f(x)=0の実数解⇔ [昭和薬大) ・基本 227 演習 233 y=f(x)のグラフとx軸の共有点のx座標に注目。 3次方程式f(x)=0 が異なる3個の実数解をもつ y=f(x) のグラフがx軸と共有点を3個もつ (極大値)>0かつ(極小値) < 0 (極大値)×(極小値) < 0 f(x)=x3ax+4aとする。 ← 3次関数では (極大値)> (極小値) 3次方程式f(x)=0 が異なる3個の実数解をもつから, 3次関数f(x) は極値をもち, 極大値と極小値が異符号 になる。 極大 y=f(x) + 1 (極大値) > 0, ( 極小値) < 0 極小 x 361 ここで,f(x) が極値をもつことから, 2次方程式(x) = 0 は異なる2つの実数解をもつ。 して f(x)=3x²-3a2=3(x+a)(x-a) f(x) = 0 とすると [x=±a このとき,f(x)の増減表は次のようになる。 >0の場合 a< 0 の場合 x 04=0のとき,f(x)=x となり極値をもたない。 x .... -a a f'(x) + 0 - 20 f(x) 極大 \ 極小 a -a 0 0 + f'(x) + + f(x) 極大 \ 極小 > f(-a)f(a) <0から (2α+4a) (-2a+4a) <0 すなわち 4a²(a2+2)(a2-2)>0 4a2 (α2+2)>0であるから a²-2>0 したがって a<-√2,√2<a αの正負に関係なく, x=α, -αの一方で極大, 他方で極小となる。 (極大値)×(極小値) =f(-a)f(a) <(a+√2)(a-√2) > 0 α≠0 を満たす。 3次方程式の実数解の個数と極値 3次方程式 f(x) = 0 の異なる実数解の個数と極値の関係をまとめると、次のようになる。 ① 実数解が1個 ② 実数解が2個 極値が同符号 または 極値なし 極値の一方が 0 ③実数解が3個 極値が異符号 a a Bx f(a)f(B)>0 α f(a)f(B)=0 pet a f(x)f(B)<0

対話文 ■平成27年度問題 2 次の英文は,由貴 (Yuki) と健太 (Kenta) が ジョーンズ先生 (Mr. Jones) と会話を している場面である。 これを読んで,後の各問に答えよ。 EN Mr. Jones: Hi, Yuki and Kenta. Kenta : Hi, Mr. Jones. Yuki : Hello, Mr. Jones. Mr. Jones: What are you going to do this weekend? Toob I Kenta : I will go to Asahi Park with my dog. I go there with him every weekend. Yuki : Oh, do you? I'm going to visit a pet shop with my family to buy a dog. ①I (wanted, am, one, for, have ) a long time. 1 Kenta Mr. Jones I like dogs very much. Do you have any pets, Mr. Jones? Yes. I have a cat. I got her at an animal shelter. Kenta Mr. Jones : Animal shelter? Yuki Kenta And I am still Right. It's a home for animals without owners. In fact, some of them were abandoned by their owners. : Really? I don't want to be an owner like them. : Why did you get your cat at an animal shelter? Mr. Jones: I heard about shelters from one of my friends and I was interested in them. Then I visited an animal shelter and saw many animals without owners in cages. 2 A volunteer ( standing, front, of, was, in ) a cage said, “They need new owners." So I got my cat from the shelter. Kenta Yuki Mr. Jones Yuki : I see. It's important to take care of pets with love. : I agree. I hope all pets will be happy with kind owners. My cat is a treasure for my family now. an animal shelter? : This evening I will talk to my family about it. I want to get a dog there and live with it. I hope it will be my good friend.
