Answer:

3.5 km

Step-by-step explanation:

We know that 1000 meters = 1 kilometer

500 meters * 1 kilometer/1000m = 500/1000 kilometer = .5 km

He goes .5 km per day

There are 7 days in 1 week, so multiply by 7

7 * .5 km = 3.5 km

Define the following sequence recursively: 96, 48, 24, 12, ....

Naddika [18.5K]

Answer:

I do not see that any of your options will work.

Step-by-step explanation:

a) and b) have a false first statement because f(1) = 96, not 12

c) would create the sequence 96, 1152, 13824

d.) would create the sequence 96, 192, 384. 768...

I believe the correct answer would be

f(1) = 96 f(n) = ½f(n-1) n ≥ 2

which could be either c) or d) if taking potential typographic errors into account. Recording a "2" or "12" where a "½" ought to be.
