I think the correct answers are:
f ----> d
<span>f' ----> c
</span><span>f'' ---> b
</span><span>f''' ---> a
f' signifies the slope of the function f. so f" is the slope of the slope and so on.</span>
Answer:
45.6° (1 d.p)
Step-by-step explanation:
Using the cosine rule;
c = √( a² + b² - 2ab Cosx)
11 =√(8² + 15² - 2 (8) (15) Cosx)
11² = 8² + 15² - 240 Cosx
11² - 8² - 15² = - 240 Cosx
-168 = -240 cosx
cosx = 0.7
x = cos⁻¹ (0.7) = 45.57 ≈ 45.6°
