I think the answer would be e. as a society, we tend to depend on vehicles to get us from one place to the other. carpooling has become popular due to there being 1 vehicle rather than 4. or 5. saves pollution and cuts down on the petroleum used to reach the same destination.

Explain in detail, how you solved the following problem: The first two terms of a sequence are 10 and 20. If each term after the

KIM [24]

Answer:

$T_{2020} = 15$

Explanation:

Given

$T_1 = 10$

$T_2 = 20$

Each term after the second term is the average of all of the preceding terms

Required:

Explain how to solve the 2020th term

Solve the 2020th term

Solving the 2020th term of a sequence using conventional method may be a little bit difficult but in questions like this, it's not.

The very first thing to do is to solve for the third term;

The value of the third term is the value of every other term after the second term of the sequence; So, what I'll do is that I'll assign the value of the third term to the 2020th term

This is proved as follows;

From the question, we have that "..... each term after the second term is the average of all of the preceding terms", in other words the MEAN

$T_{n} = \frac{\sum T{k}}{n-1} ; where: k = 1 .... n -1$

Assume n = 3

$T_{3} = \frac{T_1 + T_2}{2}$

Multiply both sides by 2

$2 * T_{3} = \frac{T_1 + T_2}{2} * 2$

$2T_{3} = T_1 + T_2$

Assume n = 4

$T_{4} = \frac{T_1 + T_2 + T_3}{3}$

$T_{4} = \frac{(T_1 + T_2) + T_3}{3}$

Substitute $2T_{3} = T_1 + T_2$

$T_{4} = \frac{2T_3 + T_3}{3}$

$T_{4} = \frac{3T_3}{3}$

$T_{4} = T_3$

Assume n = 5

$T_{5} = \frac{T_1 + T_2 + T_3 +T_4}{4}$

$T_{5} = \frac{(T_1 + T_2) + T_3 +(T_4)}{4}$

Substitute $2T_{3} = T_1 + T_2$ and $T_{4} = T_3$

$T_{5} = \frac{2T_3 + T_3 +T_3}{4}$

$T_{5} = \frac{4T_3}{4}$

$T_{5} = \frac{(5-1)T_3}{5-1}$

Replace 5 with n

$T_{n} = \frac{(n-1)T_3}{n-1}$

(n-1) will definitely cancel out (n-1); So, we're left with

$T_{n} = T_3$

Hence,

$T_{2020} = T_3$

Calculating $T_3$

$T_{3} = \frac{10 + 20}{2}$

$T_{3} = \frac{30}{2}$

$T_{3} = 15$

Recall that $T_{2020} = T_3$

$T_{2020} = 15$

The half-life of carbon-14 is about 5700 years. If you left those 100 carbon-14 atoms to sit around for 5700 years, how many wou

katovenus [111]

Answer:

50 atoms of carbon-14

Explanation:

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

Original amount (N₀) = 100 atoms

Half-life (t½) = 5700 years

Time (t) = 5700 years

Amount that decay =?

Next, we shall determine the number of half-lives that has elapse. This can be obtained illustrated below:

Half-life (t½) = 5700 years

Time (t) = 5700 years

Number of half-lives (n) =?

n = t / t½

n = 5700 / 5700

n = 1

Next, we shall determine the amount remaining. This can be obtained as follow:

Original amount (N₀) = 100 atoms

Number of half-lives (n) = 1

Amount remaining (N) =?

N = 1/2ⁿ × N₀

N = 1/2¹ × 100

N = 1/2 × 100

N = 50 atoms

Finally, we shall determine the amount that decayed as follow:

Original amount (N₀) = 100 atoms

Amount remaining (N) = 50 atoms

Amount that decay =?

Amount that decay = N₀ – N

Amount that decay = 100 – 50

Amount that decay = 50 atoms

Therefore, 50 atoms of carbon-14 have decayed during the time.

What does the author mean on page 4 Passage 2 when he says that Sir Kay “player his hand like a major—and took every trick” ?

pickupchik [31]

Answer:

Sir Kay was not easily fooled

Explanation:

This is a figurative expression that means that sir kay was not one who could be fooled so easily. From the sentence before this expression, it is stated that sir kay was equal to the occasion based on the fact that lots of eyes rested on him. The expression suggests that he knows every trick and so he was not the kind of person who could be bought over easily.
