Answer:

The answer is yes, because 2 × 10⁶ < 18,400,000, human can distinguish pixels on a same-sized HDTV.

Step-by-step explanation:

Step 1:

2⋅10⋅10⋅10⋅10⋅10⋅10 = 20⋅10⋅10⋅10⋅10⋅10 = 200⋅10⋅10⋅10⋅10 = 2,000⋅10⋅10⋅10 = 20,000⋅10⋅10 = 200,000⋅10 = 2,000,000

Step 2:

Because 2 × 10⁶ < 18,400,000, human can distinguish pixels on a same-sized HDTV.

Consider the following arithmetic progression 6, 14, 22, 30, …, 1438 A. Find the number of terms B. Determine the sum using Gaus

dlinn [17]

There is a difference of 8 between consecutive terms:

6 = 6

6 + 8 = 14

6 + 8 + 8 = 22

6 + 8 + 8 + 8 = 30

and so on. The n'th term of the progression is then 6 + 8(n - 1). This means the last term is 180th in the sequence, since

1438 = 6 + 8(n - 1) ==> 1432 = 8(n - 1) ==> 179 = n - 1 ==> n = 180

Let S be the sum of the series,

S = 6 + 14 + 22 + 30 + ... + 1438

Reversing the series, we have

S = 1438 + 1430 + 1422 + 1414 + ... + 6

Adding together terms in the same position gives

2S = (6 + 1438) + (14 + 1430) + (22 + 1422) + ... + (1438 + 6)

2S = 1444 + 1444 + 1444 + ... + 1444

We know there are 180 terms in the progression, so there are 180 copies of 1444 on the right side,

2S = 180 * 1444 ==> S = (180 * 1444)/ 2

and so the sum is S = 129,960.

What is the answer to 6/2(1+3)?

Kaylis [27]

Use PEMDAS to figure out which expression to work out first:

Parentheses
Exponents
Multiplication/Division
Addition/Subtraction

First, we'll want to solve the term with parentheses:

$2(1+3) = 2(4) = 2 \times 4 = 8$

The equation should now look like this:

$6 \div 8$

Divide to get your answer:

$6 \div 8 = 0.75$

The answer is 0.75.
