A small country emits 120,000 kilotons of carbon dioxide per year. In a recent global
Svetradugi [14.3K]

The total carbon dioxide that the country would emit over the course of the 6 year period is 661,505 kilotons.

<h3>What is the total carbon dioxide that would be emitted?</h3>

The formula that can be used to determine the emission each year is:

Emission in the first year x(1 - rate of decrease)^number of years

Emission in the first year = 120,000

Emission in the second year = 120,000 x (1 - 0.034)^1 = 115,920

Emission in the third year = 120,000 x (1 - 0.034)^2 = 111,978.72

Emission in the fourth year = 120,000 x (1 - 0.034)^3 = 108,171.44

Emission in the fifth year = 120,000 x (1 - 0.034)^4 = 104,493.61

Emission in the sixth year = 120,000 x (1 - 0.034)^5 = 100,940.83

Sum of emissions from the first year to the sixth year = 661,505

This illustrates the concept of exponential decrease.

Answer:

1.55 feet.

Step-by-step explanation:

From the question given above, the following data were obtained:

Angle R = 24°

Hypothenus = RS = 3.8 feet

Opposite = ST = x

The value of x can be obtained by using the sine ratio. This is illustrated below:

Sine R = Opposite / Hypothenus

Sine 24 = x / 3.8

Cross multiply

x = 3.8 × Sine 24

x = 3.8 × 0.4067

x = 1.55 feet

Thus, the Lenght ST is 1.55 feet.
