不懂

A )⑧. 如右圖,若將一個正方形的四 邊中點連接成另一個正方形, A2 Bi A3 則依照此規律,請問此正方形 D2 D3 B3 B 的邊長將成為何種數列,且其 公差(比)為何? C3 Di C2 C₁ (A)等比數列,公比= 12 (B)等比數列,公比= 2 (C)等差數列,公差= = 1 2 (D)等差數列,公差= V2 2 09.承上題,若四邊形A、B、C、D的面積為64平方單 位,則四邊形ABCD的面積為多少平方單位? (1) (A) 16√2 (B) 16 (C) 8√2 (D) 8

請問這兩個題型不是一樣的嗎？為什麼一個是只有一個答案，另一個是多選？不太懂這種要怎麼解 謝謝🙏

己知坐標空間中有 A(-1,1,2) B(2,3,1) C(3,-1-4) 吉ABCD為平行四邊形 則D點坐標為?

想請問各位大神，化學高二題目。老師給的線索是要利用p1-p2=ρgh解題。求詳解🙏

D3 A³ (31-33) ATT News June 23, 2022 A 300 kg stingray that was caught in the Mekong River in Cambodia on June 13, 2022 is the world's largest known freshwater fish. The fisherman who caught it was given $600 for his catch. The stingray was then freed the following day. Look at the chart below. A 293 kg Mekong giant catfish was caught in the Mekong River in Thailand in 2005. It was then the largest freshwater 4 m long and 300 kg. fish that was ever found. JHS D B³1 31. Which idea is talked about in the second paragraph of the news? (A) What has happened to the Mekong River. (B) Why the giant stingray is something special. What kinds of fish are common in freshwater. (D) What the team of scientists would do with the giant stingray. The stingray which was caught on June 13, 2022 broke the world record: When a team of scientists heard about the news of the giant stingray, they hurried to Cambodia to study it. All of them were very surprised to see the stingray because it is hard to find a large fish like it in freshwater. Large fish need large areas of water to live in, and it takes them a long time to grow to be this big. This giant fish is also a good sign for the Mekong River because it means the river is still healthy enough for fish. Scientists today have little understanding about stingrays, so the team put a device on the giant stingray before setting it free. They hoped that by studying it, they could learn more about this special fish in years to come. chart record scientist ## device 32. Who might find the news helpful? (A) Andy, who enjoys fishing. (B) Lisa, who is interested in how to study fish. (C) Amanda, who wants to study the history of Cambodia. (D) Ted, who wants to know more about large freshwater fish. 文特题店 根準化的測驗 paragraph # 33. According to the news, which is true? (A) The 300 kg stingray swam back to the river with a device on it. (B) Large fish about 300kg are common in the Mekong River. (C) Scientists already have a good knowledge of stingrays. (D) In 2005, another giant freshwater fish was also found in Cambodia. Thailand 10 請翻頁繼續作答 (111903-E) according to
