Answer:
347 is the initial spider population
Step-by-step explanation:
y = ab^x
is the formula for exponential growth and decay
a = the initial value
b is the growth or decay rate
b>1 it is the growth rate (b-1) is the percent
0<b<1 it is the decay rate (1-b) is the percent
y = 347(1.2)^x
347 is the initial spider population
(1.2-1) = .2 = 20 % growth rate
Answer: a and d
Step-by-step explanation:
First of all, we need to make a analysis of each letters:
a. factoring 32 = 2.2.2.2.2 = 

then,
16 = 
but 
in conclusion that, this inequality is correct
b. 27 = 
this first situation is equal to 
the second situation is:
81 = 
and 
it's a mistake.
c. factoring 9: 
< 
it's wrong.
d. factoring 8 = 
factoring 32 = 
> 
This is true.
Finally.. our correct answers is a and d.
