為什麼不能寫Iceland,where people can see the northern lights is one of the world’s best place.

But for Jason's Vecue timely the cat nigh Homw 5. 冰島是人們可以看到北極光的世界上最佳地區之一。

請問哪裡算錯🙏🏻

24 10. 如右圖所示(只是示意圖),將梯子AB靠在與地面垂直的牆AC上,測 得與水平地面的夾角∠ABC為60°。將在地面上的底B沿著地面向外拉 51公分到點F(即FB=51公分),此時梯子EF與地面的夾角<EFC之 正弦值為sin∠EFC=0.6,則梯子長AB=234公分。 答 51+2x=41x tos 2 I fx = 5/102 x=34 200 E 5x BX 170 【答對率39%】 107學測 5x 2 4x

想問為什麼元素表第六和第七週期都有32個元素

6. 西元 2005 年,科學家利用鈣-48的原子核撞擊含有鉲-249原子核的樣品後,偵測 E 到原子序 118 的元素,其質量數為294。此元素最有可能與下列哪一元素屬於同一族? (A)鋰(B)鎂(C)鍺(D)硫(E)氬。118=2+8+8+18+18+32+32 3.分利 7.目前尚無法測得原子序118元素的游離能,試根據右上圖的規律,推測此原子的第一 √ 游離能最有可能為下列何者(單位:kJ/mol)?

求二題詳解！！！

2.設為實數,已知lim 解 2. 解 x→0 √x+k² + K x 力 1 4 , 試求k之值。

求問兩題詳解！！ 為何是非那題不正確？

觀念是非題:正確請填,錯誤請填×,每題2分,共10 ) 1. 已知lim f(x) x→1 g(x) -- 1 , 則lim f(x)=1且limg(x)=2。 2 x→1 x→1 ( O ) 2. 已知多項式函數f(x)f(2)=5,則limf(x)=5 x→2 X)3. 設f(x)三因為高斯函數,則lim[x]不存在。

請問為什麼不能選(A)？ 謝謝🙂
