The answer is b.
when x decreases, f(x) decreases.

D. Apple’s market share fell about 4% from 2012 to 2013.
First, find the hypotenuse of the triangle with leg lengths 4 and 4. Use special triangle theorem:
1:1:sqrt(2) 4:4:4*sqrt(2)
Use the Pythagorean Theorem to find x:
2^2 + (4sqrt2)^2 = x^2
x^2 = 36
x = 6, or choice (D).
Answer:Marvin burned more calories per hour.
Step-by-step explanation:
Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Converting 2 1/2 hours to improper fraction, it becomes 5/2 hours
This means that the amount of calories that Thomas burnt in 1 hour would be 657 × 2/5 = 262.8 calories per hour
Marvin decided to go for a bike ride and burned 1,035 calories in 3 1/4 hours. Converting 3 1/4 hours to improper fraction, it becomes 13/4 hours
This means that the amount of calories that Thomas burnt in 1 hour would be 1035 × 13/4 = 3363.75 calories per hour
Therefore, Marvin burns more calories per hour.
