Step-by-step explanation:
Answer:
Therefore, the the world's predicted population in the year 2020 is 7,911×10^6 people.
Step-by-step explanation:
Given:
P₀ = 5,642×10^6 people,
i = 1.3% = 0.013 per year,
n = 2020 - 1994 = 26 years,
We get:
Pn = P₀ e^(i.n)
. . .= 5,642×10^6×e^(0.013×26)
. . .= 7,911×10^6 people
30 x 30 = 900 too low
40 x 40 =1600 too high - so the answer lies somewhere between
30 x 31 (too low) 39 x 40 = too high
31 and 37 are the only primes between those numbers and that is her pin 3137
The sum is 7. 012 × 10^-8. Option C
<h3>What is index form?</h3>
Index form is defined as the power or exponent which is raised to a number or a variable.
For example, in number 5^2, 2 is the index of 5.
Indices is the plural form of index.
To add index forms, we need to note the following:
- Both the exponents and variables should be same
- Add the coefficients of the variables leaving the exponents unchanged.
- Only terms that have same variables and powers are added
Given:
(3.012 x 10−8) + (4 x 10−8)
3. 012 + 4 (10^-8)
7. 012 × 10^-8
Thus, the sum is 7. 012 × 10^-8. Option C
