Answer:
B
Step-by-step explanation:
18 x 2 = 36
20 x 2 = 40
36 + 40 = 76 miles
Given that the rate of Uranium decay is 57%, this means that after each day, only 0.43 of the mass from the prior day is left. The equation that would best represent the scenario is,
a(t) = a₁(0.43^t)
where a(t) is the mass after t days and t is the number of days. Substituting,
a(t) = 3,280(0.43^15)
= 0.01 lbs.
so let's firstly find the component form of "u", keeping in mind that "v" is really in the opposite direction and twice as long, so v = -2u.
