Answer:

47.3\,m of garland is required for the length of the ceiling.

Step-by-step explanation:

Width of a rectangle ceiling (w)=42 \,m

Diagonal of a rectangle ceiling (d)=70\,m

Let l denotes length of a rectangle ceiling.

The relationship between length, width and diagonal of a rectangle is given as follows:

d^2=l^2+w^2\\70^2=l^2+42^2\\4900=l^2+1764\\l^2=4900-1764\\l^2=2236\\l=47.3\,m

So,

47.3\,m of garland is required for the length of the ceiling.

During a speech in 2014, one of Intel’s vice presidents said that, by 2026, the company would make a processor with as many tran
dangina [55]

The Moore's law is a rule of thumb that gives an idea of the processors that a company can expect to produce with time.

Response:

  • Based on Moore's law the vice president's statement predicting the number of transistors in a processor in 2026 is correct.
<h3 /><h3>Detailed reasons for the above response</h3>

Based on online search, the minimum transistor count data in 2014 = 1,400,000,000

Moore's Law states that the number of transistors in an integrated circuit is expected to multiply by a factor of 2 every two years.

Mathematically, we have;

  • Pₙ = P₀ × 2ⁿ

Where:

Pₙ = The processing power of a computer in future years

P₀ = Processing power of a computer at the start of the current year

n = The number of years divided by 2

The expected processing power in 2026 is therefore;

n = (2026 - 2014) = 12 ÷ 2 = 6

P₆ = 1,400,000,000 × 2⁶ = 89,600,000,000 = 8.96 × 10¹⁰

The given number of neurons in a human brain = 1.0 × 10¹¹

The difference = 1.0 × 10¹¹ - 8.96 × 10¹⁰ = 1.04 × 10¹⁰

  • The difference is less than 1/8 of the expected transistor count, therefore, the vice president's statement can be taken as correct.
