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.

A= π r ²
Take half of the diameter for the radius, so the radius is 2m
A=π 2 ²
A= 12.57 m²
So, yes, you are correct

Step-by-step explanation:
Answer:
6.3 x 10°
Step-by-step explanation:
6.3 can be written as 6.3 x 1
recall that anything to the power of zero = 1
hence 10° = 1 substitute this back into the expression above to get:
6.3
= 6.3 x 1
= 6.3 x 10°
Answer:
k=6
Step-by-step explanation:
150=25×6=5²×6
For 150k to be a perfect square, it is necessary that 5²×6×k to be a perfect square.
This is accomplished when k=6 (smallest value)
k=6, 150k=5²×6²=(5×6)²=30²
