Step-by-step explanation:
The population of rabbits on an island is growing exponentially. In the year 1994, the population of rabbits was 9600, and by 2000 the population had grown to 18400. Predict the population of rabbits in the year 2009, to the nearest whole number.
Answer:
49243
Step-by-step explanation:
Given that the population of rabbits on an island is growing exponentially.
Let the population, [tex]P=P_0e^{bt}[/tex]
where, [tex]P_0[/tex] and b are constants, t=(Current year -1994) is the time in years from 1994.
In 1994, t=0, the population of rabbit, P=9600, so
[tex]9600=P_0e^{b\times 0}[/tex]
So, [tex]P_0=9600[/tex]
and in 2000, t=2000-1994=6 years and population of the rabbit, P=18400
[tex]18400=9600 \times e^{b\times 6} \\\\\frac{18400}{9600}=e^{b\times 6} \\\\[/tex]
[tex]\ln(23/12}=6b \\\\[/tex]
[tex]b = \frac{\ln{1.92}}{6} \\\\[/tex]
b=0.109
On putting the value of P_0 and b, the population of the rabbit after t years from 1994 is
[tex]P=9600 \times e^{0.109\times t}[/tex]
In 2009, t= 2009-1994=15 years,
So, the population of the rabbit in 2009
[tex]P=9600 \times e^{0.109\times 15}=49243[/tex]
Hence, the population of the rabbit in 2009 is 49243.

Janiya hiked 4/5 of a mile in 1/3 of an hour what is the hiking speed in miles per hour
Answer:
Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.
Step-by-step explanation:
Given that:
Distance covered = 4/5 of a mile
Time taken to cover the distance = 1/3 of an hour
Speed is defined as the distance travelled in a certain time.
Speed of Janiya = [tex]\frac{Distance}{Time}[/tex]
Speed of Janiya = [tex]\frac{\frac{4}{5}}{\frac{1}{3}}[/tex]
Speed of Janiya = [tex]\frac{4*3}{5*1}[/tex]
Speed of Janiya = [tex]\frac{12}{5}[/tex]
Speed of Janiya = [tex]2\frac{2}{5}[/tex] miles per hour
Hence,
Janiya has a speed of [tex]2\frac{2}{5}[/tex] miles per hour.

James wants to buy some CDs that cost $14 each and a DVD that costs $23. He has $65. Write an equation (in the Show your work area) and solve to find how many CDs he can buy. Include "CD" in your answer.
Answer:
3
Step-by-step explanation:
65-23= 42
42/14= 3
Answer:
14x+23 =65 x=3CDs
Step-by-step explanation:
So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.
To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.
I hope this helps.

The table below contains data on how many pages were read for homework in Mr. Kaplinsky's third period. The equation of the line of best fit for the data is y = 28.3x + 4.8. Which two statements accurately describe the slope for the line of best fit? About 28.3 pages were read each hour. The most that any student can read is 4.8 pages per hour. For each additional hour spent reading, approximately 4.8 additional pages can be read. If a student starts reading faster, they will read 28.3 more pages in each additional hour they read. If a student reads for 1 hour longer than another person, they will have read approximately 28.3 more pages.
Answer:
28.3
