Answer:
25%
Step-by-step explanation:
The first doubling, from 20 to 40 occurs in a little more than 3 years, so the multiplier each year is a little less than 2^(1/3) ≈ 1.26. That is, each year is a little less than 26% more than the previous year.
The graph also goes near the point (8, 120), so grows by a factor of 6 in 8 years. That suggests a multiplier of 6^(1/8) ≈ 1.251. Each year is about 25.1% more than the previous year.
Both of these multipliers represent yearly growth rates near 25%.
___
Using the "rule of 72", the product of doubling time and percentage growth is about 72. So, for a doubling time of 3 years, the percentage growth is predicted to be near 72/3 = 24 percent.
All of these estimates help you choose the correct answer: 25%.
1 and 2 are supplementary angles. The sum of their measures is equal to 180 degrees.
I hope this helps. =)
A scientist has collected the following data on the population of a bacteria colony over a thirty-minute period:
5 minutes: 78,000
10 minutes: 234,000
15 minutes: 657,000
20 minutes: 1,784,000
25 minutes: 5,040,000
30 minutes: 14,980,000
Which type of graph would be best to use to display the growth of the colony?
A.) a bar graph
B.) a circle graph
C.) a histogram
D.) a line graph
An bar graph suits the best in this type of study because we can easily understand the growth and decrease of that particular thing which is being studied.
Out of the choices given, the prediction for the population after 4 years is about 1, 624 deer. The correct answer is B.
Answer:
y= -0.5 x +3
Step-by-step explanation:
at x=0 , y=3
at x=2 , y=2
y= ax+b
b=3
2=2a+3
2a= -1
a= - 0.5
then
y= -0.5 x +3
