the answer is 10-3n please do you get it
Answer:
aₙ = 1/2 x aₙ₋₁ n≥2
Step-by-step explanation:
aₙ = 1/2 x aₙ₋₁ n≥2
a₁ = 64
a₂ = 1/2 x 64 = 32
a₃ = 1/2 x 32 = 16
Answer: 35 pies
Step-by-step explanation:
Ken can bake 1 pie with each additional cup of sugar he buys. 1 pie =1 cup
4 + x = y
Where;
x= additional pies
y= total pies
If 1 cup= 1 pie; then 31 cups =
31 cup × 1 pie/1 cup = x
:. x= 31 pies
y= x + 4
y= 31+4 = 35
C
the sum to infinity of a geometric series = 
where a is the first term and r the common ratio
=
= 81 × 3 = 243
Answer:


Step-by-step explanation:
We are given that there is an exponential decay.
Also, the decrease is of constant rate 7.9% i.e. 0.079 each year.
Since, the initial amount of the species is atleast 26 million.
Thus, the inequality for the corresponding model will be,
,
where t is the time period for the decay and P is the population.
Moreover, is is given that the population cannot be less than 2 million.
So, we get,
.
Hence, the inequalities to determine the possible number of insects over time are given by,

.
