Answer:
<h3>i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰ =
0</h3>
Step-by-step explanation:
Consider the sum S = i¹ + i² + i³ +. . .+ i⁹⁹ + i¹⁰⁰
S = i¹ + i² + i³ + . . . + i⁹⁹ + i¹⁰⁰
S = a₁ + a₂ + a₃ +. . . + a₉₉ + a₁₀₀
then, S is the sum of 100 consecutive terms of a geometric sequence (an)
where the first term a1 = i¹ = i and the common ratio = i
FORMULA:______________________
_______________________________
then
or i¹⁰⁰ = (i⁴)²⁵ = 1²⁵ = 1 (we know that i⁴ = 1)
Hence
S = 0
Answer:
Iron: 280m³
Zinc: 105m³
Tungsten: 35m³
Step-by-step explanation:
8+3+1 = 12
(8/12)×420 = 280
(3/12)×420 = 105
(1/12)×420 = 35
Answer:
There needs to be more information
Step-by-step explanation:
Assuming that the traps stay the same, we know that the number of moths they catch will be relative to the size of the population of moths. From this, we can see that the trend in the population of light moths is a steady decrease from year to year, and the trend in the population of the dark moths is a steady increase over the same time period.
Since the trees have been darkened by industrial pollution (they have black smoke on them), we know that the dark moths camouflage better than the light moths. Because of this, the white moths get eaten by predators more often and their population goes down gradually; the dark moths, however, camouflage easily, and their population goes up since they get eaten less often.
If the environment were cleaned up, the light moths' population would increase (since they camouflage better on clean trees), while the dark moths' population would decrease (since they camouflage better on dirty, polluted trees).
