题目

如图在平面直角坐标系中，O为原点，A、B两点分别在y轴、x轴的正半轴上，△AOB的一条内角平分线、一条外角平分线交于点P，P在反比例函数的图像上．（1）求点P的坐标；（2）若OA＝OB，则①∠P的度数为 ；②求出此时直线AB的函数关系式；（3）如果直线AB的关系式为y＝kx＋n，且0＜n＜2，作反比例函数，过点P(0，1)作x轴的平行线与的图像交于点M，与的图像交于点N，过点N作y轴的平行线与y＝kx＋n的图像交于点Q，若MN＋QN的和始终是一个定值d，求此时k的任务型阅读Dear Nancy,I am happy to tell you my school and my life(生活). From Monday to Saturday I get up at six and I go to school on foot. My school is very big and beautiful. I like my school very much. The desks and chairs are new. There are lots of pictures on the walls. You can also see some flowers on the teachers’ desk. We clean the classroom every day.I don’t go to school on Sunday. I get up at about seven on Sunday. My father and I play basketball in the park near my home. Then I eat my breakfast. I help my mother wash clothes at home and water flowers in the garden. At nine I begin to do my homework. My parents and I have lunch in the KFC. In the afternoon, my parents and I often go to visit my grandparents. Sometimes I play computer games or write emails to my friends in the evening.I like my Sunday very much.YoursLi HuaA letter(信) from Li Hua to Nancy.It 【1】 Nancy about his school and his life.School◆It’s big and 【2】 .Life from Monday to Saturday◆He goes to school 【3】 days a week and he 【4】 toschool.Life on Sunday【5】 ◆He often plays basketball 【6】 his father and helps his mother 【7】 clothes.◆He does his 【8】 at 9 o’clock.Afternoon◆He and his parents often 【9】 his grandparents.Evening◆Sometimes he likes 【10】 emails to his friends.
