The population of cuba is 1.3 million. the country's population is expected to grow at a rate of 4% each year. the population of cuba will be million in 10 years.

The population growth will be modeled using exponential growth:

f(x)=a(b)^t

where:

a=initial value

b=growth rate

thus plugging in the values we get:

f(x)=1.3(1.04)^t

thus the population after 10 years will be:

f(x)=1.3(1.04)^10

f(x)=1.9243

thus the population in 10 years will be:

1.9243 million

Hope this helped!

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
