Answer:
B. 
Step-by-step explanation:
The question is not properly presented. See attachment for proper presentation of question
From the attachment, we have that:




Required
Order from greatest to least
First, we need to simplify each of the given expression (in decimals)



Take square root of 3


--- approximated



Take π as 3.14


--- approximated
List out the results, we have:

Order from greatest to least, we have:

Hence, the order of arrangement is:

i.e.

-3.7n - 4 = -11.9
if u want to solve it them add 4 to -11.9 which is -7.9. -7.9 / -3.7 is 2.13513514. (if you wanted to solve it)
Answer:
D
Step-by-step explanation:
Answer:
170 heart beat per minute.
Step-by-step explanation:
While exercising, a person’s recommended target heart rate is a function of age. The recommended number of beats per minute, y, is given by the function y = f(x) = − 0.85x + 187 where x represents a person’s age in years.
So, if my age is 21 years i.e. x = 21, then the number of recommended heart beats per minute for my age will be
y = f(21) = - 0.85(21) + 187 = - 17.85 + 187 = 169.15 ≈ 170. (Answer)
