Answer:
A number line going from negative 12 to positive 12. Points are at negative 8, negative 4, and 11.
Step-by-step explanation:
In a number line plot, each integer number of interest is represented by a point.
The number line that plots the integers –8, –4, and 11 is the number line where –8, –4, and 11 are present
Answer:
the answer is 8
Step-by-step explanation:
8x6=48
Answer:
Hence after period of 9 years from 1990 t0 1999 will be 61438 rabbits.
Step-by-step explanation:
Given:
Population for rabbit obeys exponential law.
120 at 1990 and 240 1991 ...after 1 year time period
To Find:
After 9 year time period how many rabbits will be there.
Solution:
Exponential law goes on present value and various value and time period and defined as ,
let Y be present value Y0 previous year value and k exponential constant and t be time period.
So
Y=Y0e^(kt)
Here Y=240 ,Y0=120 t=1 year time period
So
240=120e^(k*1)
240/120=e^k
2=e^k
Now taking log on both side, [natural log]
ln(2)=ln(e^k)
ln(2)=kln(e)
k=ln(2)
k=0.6931
For t=9 year of time period
Y0=120, t=9 ,k=0.6931
Y=Y0e^(k*t)
Y=120*e^(0.6931*9)
=120e^6.2383
=61438.48
=61438 rabbits
She will need to babysit for 213 hours
You do 5.5x4=22, so you can drive 22 miles for every gallon of gas.
