The function 
represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.
<h3>Population Growth Equation</h3>
The formula for the Population Growth Equation is:
Pf= future population
Po=initial population
r=growth rate
t= time (years)
growth or decay factor = (1 ±r)
When 1+R > 1, the equation represents growth, while 1+R < 1 the equation represents decay.
The question gives:
, then
Pf=y
Po= 1
, thus
r= -70%= -0.7
decay factor= (1-0.7)=0.3
Therefore,
1+R will be = 1+(-0.7)=1 - 0.7 =0.3
When 1+R >1, the function represents exponential growth.

Answer:
2xy/2 = money for 1 charity
Step-by-step explanation:
2 lemonades for each day (x) = 2x
amount of money made = 2xy = no of lemonades sold x profit of 1 lemonade
two charities = 2xy/2 = total profit divided by no of charities
Answer:
c
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
the probability it would snow is 0.07 or 7%. this is quite low. so, it is unlikely that it would snow
As long as the mass of the chip is evenly distributed on each side, whatever times you flip the chip,
The probability will always be 50%
