Step-by-step explanation:
1) c
2) c
use the value of slope and the coordinates and substitute in the equation of line.
Answer:
1) A
2) B
Step-by-step explanation:
For this problem we use exponential growth formulas
if the population increases when t increases
If the population decreases when t increases
Where and is the population as a function of time, 
is the initial population, r is the growth rate, t is the time in years.
1) In this situation we have that 
, the growth is 2.4%, then 
and 
and the equation is:
-------- Option A)
2) In this situation we have that 
, the decrease is 1.7%, then 
and 
and the equation is:
-------- Option B)

Answer:
2x
Step-by-step explanation:
Volume of a cylinder is:
V = πr²h
If V = 4πx³ and h = x, then:
4πx³ = πr²x
4x² = r²
r = 2x
