Answer:
the correct answer is option b. root 13
Answer:
Below.
Step-by-step explanation:
Using Pythagoras theorem:
(√69)^2 = (√47)^2 + BC^2
BC^2 = 69-47 = 22
BC = √22.
sin D = BC / CD
= √22/√69
= 0.5647 to nearest ten thousandth.
4 and 3/4
the number line goes like this: 4, 4 and one fourth, 4 and a half, 4 and three fourths, then 5.
Answer:
The country's population for the year 2030 is 368.8 million.
Step-by-step explanation:
The differential equation is:
Integrate the differential equation to determine the equation of P in terms of <em>t</em> as follows:
At <em>t</em> = 0 the value of <em>P</em> is 300 million.
Determine the value of constant C as follows:
It is provided that the population growth rate is 1 million per year.
Then for the year 1961, the population is: P (1) = 301
Then .
Determine <em>k</em> as follows:
For the year 2030, P (2030) = P (70).
Determine the value of P (70) as follows:
Thus, the country's population for the year 2030 is 368.8 million.
