Answer:
b
Step-by-step explanation:
Using the trigonometric identity
• sin²x + cos²x = 1 , hence
cosx = ± 
cosΦ > 0 for 0 < Φ < 
cosΦ =
=
=
=
→ b
Exercise 4
A grow from 13.1 millions to 14.4 millions means to grow

millions. So, the question is: which percentage of 13.1 is 1.3? Well, we have to find a number x such that

Solving for x, you have

Exercise 5
27% is a bit more than 25%, which is a quarter. So, we expect to find a pie chart with one slice occupying roughly one quarter of the pie. The example that best suits this requirement is B (A is almost half, and C is less than one quarter).
(15√6 / √5)
<span>(15√6/√5) *(</span>√5/√5)
(15*√6*√5)/(√5*√5)
15*√30 / 5
3√30
