Its the last one because you plug in the 20(x) for example y=20x
and your table looks like this
x 0/2/4
y 0/40/80 y x
because 20(2)=40 then you would do the same with the rest of the equation
20(4)= 80 there fore the last on is your answer
Answer:
11.0 years
Step-by-step explanation:
The exponential function describing the population growth can be written ...
population = (initial population)×(1 +growth rate)^years
If t represents the number of years, we can fill in the values to get ...
18500 = 12000×1.04^t
Dividing by 12000 gives ...
18500/12000 = 1.04^t
Taking logarithms, we have ...
log(18500/12000) = t×log(1.04)
t = log(185/120)/log(1.04) ≈ 11.037 ≈ 11.0
It will be 11.0 years until the population reaches 18,500.
The ratio of three numbers are 2:3:4.
Let the rational between the three numbers be x, hence the three numbers be 2x, 3x,and 4x.
If their average is 36, what are the numbers
We know the average = sum of the numbers / no. Of numbers.
(2x+3x+4x) /3=36
9x/ 3= 36
3x =36
X= 36/ 3
X= 12
The rational is 12
Answer the three number are 24, 36, and 48.
