Answer:
The 20th day
Step-by-step explanation:
On the first day, number of people who know the secret=2
Number of people On the second day =2X2=4
Number of people On the third day =4X2=8
We can see that on each passing day, the number keeps doubling.
This is an example of a geometric progression.
Now we are to determine the number of days when the number of people who know the secret will grow past 1,000,000
For the G.P. 2,4,8,...
a=2, common ratio, r= 2
Uₙ=arⁿ⁻¹
arⁿ⁻¹>1000000
2X2ⁿ⁻¹>1000000
2ⁿ⁻¹⁺¹>1000000
2ⁿ>1000000<2²⁰=1048576
2ⁿ<2²⁰
n<20
It means on the 20th day, more than 1 million people will have been told the secret
Answer:
Planter 1 is 48 meters cubed
Planter 2 is 24 meters cubed
Total volume = 72
Step-by-step explanation:
The formula for the volume of a rectangular prism is length times width times height. So, 4*4*3. This equals 48. If the other planter is half the volume, divide 48 by 2 to get 24 meters cubed. To find the total area add both results to get a total of 72 meters cubed.
