Answer:
Dan=6 days Dave=12 days
Step-by-step explanation:
1/2x + 1/x = 1/4
multiply each by 8x bc 4 * 2x = 8x
4 + 8 = 2x
12 = 2x
6 = x
Answer:
x=20
Step-by-step explanation:
10x-60=140
10x=140+60
10x=200
x=20
The answer would be 1 were to estimate
Answer:
XnY={1, 2, 3, and 4} and XuY={1, 2, 3, 4 and 5}
Answer:
Step-by-step explanation:
Exponential growth function can be represented as follows
y =
Here y increases exponentially with respect to t . As t increases , rate at which y increases is increases .or
dy / dt =by , or rate of increase depends upon y itself
dy / y = bdt
integrating on both sides
lny = bt
y = 
It represents very fast increase in y .
The unrestricted growth of population of human being is an example of exponential growth . As population increases , rate of growth of population also increases.
For exponential decay function
y = 
The decay of a radioactive material is an example of exponential decay function.
