The country of Freedonia has decided to reduce its carbon-dioxide emission by 35\%35%35, percent each year. This year the country emitted 404040 million tons of carbon-dioxide.
Write a function that gives Freedonia's carbon-dioxide emissions in million tons, E(t)E(t)E, left parenthesis, t, right parenthesis, ttt years from today.

At t years, the composition of carbon dioxide is 45 * 0.35^(t - 1) million tons

Step-by-step explanation:

Given

Current composition of carbon dioxide = 40million tons

Rate of reduction = 35%

Time = t years

The question is an arithmetic progression, asking is to calculate the nth term

To solve this, we make use of the geometric progression formula of nth term

Tn = a,r^(n-1)

Where a = first term

n = expected term

r = common ratio.

In this case

a = 45 million

r = 35% = 0.35

n = t

By substituton

At t years, the composition of carbon dioxide is 45 * 0.35^(t - 1) million tons

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
