Answer: option a. A customer earns 1 free night per 10 nights stayed.
Explanation:
Building a table can help you:
x: number of nigths stayed ---------- f(x) = 1/x: number of free nights
10 --------------------------------------------- 10/10 = 1
20 -------------------------------------------- 20/10 = 2
30 -------------------------------------------- 30/10 = 3
40 -------------------------------------------- 40/10 = 4
Then, the pattern permits you to conclude that a customer earns 1 free night per each 10 nights stayed, which is the option a.
Answer:
48.06
Step-by-step explanation:
b^2+c^2=A^2
45+16=42.06
add the extra 6
Using the trigonometric equality:
sin(x+y)=sin(x)*cos(y)+cos(x)*sin(y)
then:
<span>sin(90+θ)=sin(90)*cos(θ)+cos(90)*sin(θ)=cos(θ)</span>
