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.

Find the coordinates of the vertex of the following parabola algebraically. Write your answer as an (x,y)(x,y) point.
Serga [27]

Answer:

(8,-3)

Step-by-step explanation:

The given parabola is

y =  - 3 {x}^{2}  + 48x  - 195

We factor -3 from the first two terms to get:

y =  - 3( {x}^{2}   - 16x)  - 195

Add and subtract the square of half the coefficient of x

y =  - 3( {x}^{2}   - 16x + 64)   + 3 \times 64- 195

y =  - 3 {(x - 8)}^{2}  + 192 - 195

We simplify to get:

y =  - 3 {(x - 8)}^{2}  - 3

We compare this to y=a(x-h)²+k,

The vertex is (h,k)=(8,-3)

The price of an electronic puzzle was reduced be $7
Nimfa-mama [501]

Answer:

Step-by-step explanation:

total price was reduced by $ 7

let x = the total price........ x - 7

he bought 10.....and it cost him $ 130

10(x - 7) = 130

10x - 70 = 130

10x = 130 + 70

10x = 200

x = 200/10

x = 20 <====== original price

A biased dice was rolled and the scores recorded in the table below
dusya [7]

Given:

The table of score and frequency.

To find:

The probability that on the next roll the score will be 4.

Solution:

From the given table it is clear that the score 4 occurs 10 times.

Number of times the dice was rolled = 17 + 24 + 23 + 10 + 16 + 30

                                                             = 120

The probability that on the next roll the score will be 4 is

\text{Required probability}=\dfrac{\text{Number of times 4 occurs}}{\text{Number of times the dice was rolled}}

\text{Required probability}=\dfrac{10}{120}

\text{Required probability}=\dfrac{1}{12}

Therefore, the required probability is \dfrac{1}{12}.
