Answer:
3, 6, 12, 24
Step-by-step explanation:
This is a recursive formula which allows the next term in a sequence to be found from the previous term in the sequence
Given
= 2
with a₁ = 3, then
a₂ = 2 × a₁ = 2 × 3 = 6
a₃ = 2 × a₂ = 2 × 6 = 12
a₄ = 2 × a₃ = 2 × 12 = 24
Thus the first 4 terms are 3, 6, 12, 24
Answer:
D. 75%
Step-by-step explanation:
Percent of full retail price = 8+(1/2)(8)+(3/4)(8)/24
This simplifies to 0.75, which is equivalent to 75 percent.
$24 is full retail price so by dividing the amount Gia paid by it, you can find the percent of the full retail price.
Answer: There is increase of 4.255 in the amount of carbon in the atmosphere.
Step-by-step explanation:
Since we have given that
Concentration of carbon in Earth's atmosphere in 1800 = 280 ppm
Concentration of carbon in Earth's atmosphere in 2015 = 399 ppm
We need to find the percentage increase in the amount of carbon in the atmosphere.
So, Difference = 399-280 = 119 ppm
so, percentage increase in the amount of carbon is given by

Hence, there is increase of 4.255 in the amount of carbon in the atmosphere.
