Intel estimates that about 12 quintillion transistors are shipped around the globe each year. If that represents 10,000 times th
ra1l [238]

Answer:

Number on ants on Earth = 1.2 × 10¹⁵

Step-by-step explanation:

1 quintillion = 10¹⁸ or (1000000000000000000)

∴ 12 quintillion = 12 × 10¹⁸

12 quintillion = 10,000 × Number of ants on Earth

Let the number of ants on Earth = n

12 quintillion = 10,000 × n

dividing both sides by 10,000

12 quintillion ÷ 10,000 = n

n = \frac{12\ \times\ 10^{18} }{10,000} \\n =  \frac{12\ \times\ 10^{18} }{10^{4}}\\n = 12\ \times\ \frac{10^{18}}{10^{4}} \\applying\ the\ second\ law\ of\ indices\ (\frac{x^m}{x^n} = x ^{m-n})\\ n = 12\ \times\ 10^{(18 - 4)\\n = 12\ \times 10^{14}\\in\ standard\ form\\n = 1.2\ \times 10\ \times\ 10^{14}\\\therefore n = 1.2\ \times\ 10^{15}

Number on ants on Earth = 1.2 × 10¹⁵

Given the function f(x) = 3x + 1, evaluate f(a + 1). 3 a + 2 3 a + 4 3 a + 1
Tanya [424]

Answer:

f(a + 1) = 3a + 4

Step-by-step explanation:

Given the function is:

f(x) = 3x + 1

To determine f(a + 1) we have to substitute (a + 1) in place of 'x'.

Therefore, we have:

f(a + 1) = 3(a + 1) + 1

          = 3a + 3 + 1

          = 3a + 4

['a' could be any real number.]

So, f(a + 1) = 3a + 4 is the answer.
