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.
Answer:
Echo can plant a maximum of 8 shrubs.
The total cost for Echo's shrubs is = 8 $15.32 = $122.56
Step-by-step explanation:
i) Garden is 36 feet wide
ii) Each shrub is 4.5 feet wide.
iii) therefore the maximum number of shrubs that can be planted are
Therefore Echo can plant a maximum of 8 shrubs.
Therefore the total cost for Echo's shrubs is = 8 $15.32 = $122.56
