Summative assessment for the unit “our countryside”

Reading.

Task 1. Read Corrine’s description of a new favourite walk

Hi Emma,

I found something really great last weekend. There’s a beautiful blue river near my house,and we often sit on the river bank and play there.This time,my brother and I walked down the river a bit and we found an amazing old bridge over the river,and we went across it.                                                                                                                                                      My dad says the bridge is 80 years old. There’s an interesting little path and it goes through a wood.It’s like another world.We were there for abouttwo hours. The  path goes a long way-more than 10kilometres!We saw five different types of birds there.One was a shy yellow bird. We really loved it.The problem is that there’s a lot of litter in the wood.It’s  so sad. I want to start a group,so people can go there and help to clean up the place. I want it to be an amazing place for plants and wildlife that everyone can enjoy.So far,there are four of us in the group.                If you have free time, and know anyone who would like to help,write to me and let me know!  

Love,                                                                                                                                                    Corrine

Объяснение:

токой есть

дайте

получается делаем так:

сначала решаем уравнение как и обычно т.е. теоремой виетта или дискриминантом

х^2-4х+3=0

я решу теоремой виетта:

сумма корней равна 4

произведение 3

значит корни 1 и 3

далее:

есть такая формула разложение на множетели квадратного уравнения выглядит так:                 a(x-x1)(x-x2), где а-множетель перед квадратом в нашем случае это 1, х1 и х2 - корни. 

подставим в неё наши корни, получим  (x-1)(x-3)=0

так а теперь решим это неравенство  (x-1)(x-3)> 0

методом интегралов ( тут 3 промежутка от минус бесконечности до 1 от 1 до 3 и от 3 до плюс бесконечности):

допустим х =0, подставим (0-1)(0-3)=3 знак + значит в промежутке от минус бесконечности до 1 знак + 

от 1 до 3 знак -

от 3 до плюс бесконечности +

ответ: х принадлежит промежутку  от минус бесконечности до 1 и  от 3 до плюс бесконечности
