力學 有誰會這題😭

目前正在進行的嘗試 在圖中的俯視圖中,2.78公斤的盒子上有兩個力,但只顯示了一個。對於Fq=10.2 N = 12.3 m/s 2 和6 = 37.6°,求單位向量表示法 中的第二個力(a),以及(b)大小和(c)方向(將方向表述為從+x方向測量的負角,) F₁

請問這個如何計算

19 A藥的TC50為100mg/mL,A藥的EC50為 2mg/mL。B藥的TC50為100mg/mL,B藥的EC50 為1mg/mL,下列敘述,何者正確? ○ A. 數據不足,無法比較A藥和B藥的安全性 B. A藥安全性較大 C. A藥和B藥安全性相同 ○ D. B藥安全性較大 正確答案: D

請問這個要如何計算

11 某藥之TD50為0.5 mg/Kg,Epso為10 pg/Kg,則其治療係數(therapeutic index)為: A. 5 B. 100 OC. 500 O D. 50 正確答案: D R

求解找極限函數值或者為什麼不存在，還有想問x->-3右上的正號與x->-3有甚麼區別？還有b連題目都不太了解要求什麼,c的話有哪些不是連續的？求求各位大神了🙏

(i)_lim_ƒ(x) x−2+ (ii) lim_ f(x) x--3+ (iii) lim f(x) x--3 (iv) lim f(x) X→4 (v) lim f(x) x->0 0 (vi) lim f(x) x→2- (b) State the equations of the vertical asymptotes. (c) At what numbers is f discontinuous? Explain.

請問c7.的domain和range 是這樣寫嗎？

f(x1= Di R x 2 -2 YER X20 TECH TUTOR is the range range of f1 is the domain of f, which 2.00). ✓ Checkpoint 7 Worked-out solution available at LarsonAppliedCalculus.com Find the inverse function of f(x) = x² + 2 for x ≥ 0. After you have found an inverse function, you should check your results. You can ƒ-¹ are reflections check your results graphically by observing that the graphs of ƒ and

（大一微積分） 請問這題這樣寫正確嗎？背流程寫的😅，圖一為需用到的定義 正確的話，想問紅色圈圈的1是怎麼來的？

DEFINITION Let f be a function defined on some open interval that con- tains the number a, except possibly at a itself. Then we say that the limit of f(x) as x approaches a is L, and we write lim f(x) = L x→a if for every number &> 0 there is a corresponding number 8 >0 such that | ƒ(x) − L| < ɛ if 0 < x-a <8 then

求這題～ 答案為為 a .31cm b.866J c.1.15J

ping. What was the initial speed of the bullet? 8.43 A Ballistic Pendulum. A 12.0 g rifle bullet is fired with a speed of 380 m/s into a ballistic pendulum with mass 9.00 kg, suspended from a cord 70.0 cm long (see Example 8.8 in Section 8.3). Compute (a) the vertical height through which the pendulum rises, (b) the initial kinetic energy of the bullet, and (c) the kinetic energy of the bullet and pendulum immediately after the bullet becomes embedded in the wood. 150 kg block is attached A

求這三題（不是很確定答案）
