The population of the seven countries, arranged from least to greatest in scientific notation is: 1.38 x 10², 1.48 x 10², 1.9 x 10², 2.75 x 10², 6.53 x 10², 6.81 x 10² and 8.64 x 10².
To arrange from least to the greatest means to arrange from the smallest number to the largest number. Before we can arrange the population of the seven countries from the least to the greatest, we would need to resolve the numbers and convert to scientific notation, hence:
Population of first country = 1.37 x 101 = 138.37 = 1.38 x 10²Population of second country = 2.75 x 100 = 275 = 2.75 x 10²Population of third country = 8.56 x 101 = 864.56 = 8.64 x 10²Population of forth country = 6.37 x 107 = 681.59 = 6.81 x 10²Population of fifth country = 1.44 x 103 = 148.32 = 1.48 x 10²Population of sixth country = 1.83 x 104 = 190.32 = 1.9 x 10²Population of seventh country = 6.53 x 100 = 653 = 6.53 x 10²Therefore, if we are to arrange the population of the seven countries, starting with the smallest number and ending with the largest number in scientific notation, we will have: 1.38 x 10², 1.48 x 10², 1.9 x 10², 2.75 x 10², 6.53 x 10², 6.81 x 10² and 8.64 x 10².

The 17th term of the given geometric sequence, 3, 12, 48, 192, . . . , is 1.288490189 x 10^10.
A geometric sequence refers to a sequence of numbers, which the next term is obtained by multiplying the previous term with a constant, called a ratio.
a(n) = a r^(n-1)
Where:
a(n) = nth term
r = ratio
Given the geometric sequence 3, 12, 48, 192, . . .
Find the ratio,
r = a(n)/a(n-1)
r = a(2)/a(1)
r = 12/3
r = 4
Notice that the ratio between two succeeding terms is always 4.
Use the formula to find the 17th term of the geometric sequence.
a(n) = a r^(n-1)

Find the center and the radius of each circle. x²+y²-4 y-16=0
The center and radius of the circle given by the equation x^2 + y^2 - 4y - 16 = 0 is (0 , 2) and 2√5, respectively.
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x^2 + y^2 + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + y^2 - 4y - 16 = 0, then the coefficients are:
D = 0
E = -4
F = -16
If D = -2h and D = 0, then
0 = -2h
h = 0
If E = -2k and E = -4, then
-4 = -2k
k = 2
If F = h^2 + k^2 -r^2 and F = -16, then
-16 = 0^2 + 2^2 - r^2
r^2 = 0 + 4 + 16
r^2 = 20

A major fishing company does its fishing in a local lake. The first year of the company's operations it managed to catch 175,000 fish. Due to population decreases, the number of fish the company was able to catch decreased by 8% each year. How many total fish did the company catch over the first 10 years, to the nearest whole number?
The company catches 1,237,275.5 fishes over 10 years.
Given that, a company catches 175000 fishes in a year, the population decreases, the number of fish the company was able to catch decreased by 8% each year.
So, the population in 10 year =
The second year = 175000 × 0.92 = 161000
The third year = 161000 × 0.92 = 148120
The fourth year = 148120 × 0.92 = 136,270.4
The fifth year = 136270.4 × 0.92 = 125368.8
The sixth year = 125268.8 × 0.92 = 115339.3
The seventh year = 115339.3 × 0.92 = 106112.2
The eighth year = 106112.2 × 0.92 = 97623.2
The ninth year = 97623.2 × 0.92 = 89813.3
The tenth year = 89813.3 × 0.92 = 82628.3
The total = 175,000+161000+148120+136,270.4+125368.8+115339.3+106112.2+97623.2+89813.3+82628.3 = 1,237,275.5

How many minutes were used during a month if the cost amounted to $43.53 ?
O 506 minutes
O 426 minutes
O 388 minutes
438 minutes
Answer:
c) 388 minutes
Step-by-step explanation:
Given equation,
→ C = 29.95 + 0.035x
Then the call duration will be,
→ C = 29.95 + 0.035x
→ 43.53 = 29.95 + 0.035x
→ 0.035x = 43.53 - 29.95
→ x = 13.58/0.035
→ [ x = 388 ]

What is the slope of a line perpendicular to the line whose equation is x+4y=16x+4y=16. Fully simplify your answer.
The slope of a line perpendicular to the line of x + 4y = 16 is 4.
What is the slope of a line perpendicular to the line of the given equation?Given the equation of line;
x + 4y = 16
First, rearrange in slope intercept form ( y = mx + b ) by solving for y
x + 4y = 16
Subtract x from both sides
x - x + 4y = 16 - x
4y = -x + 16
Divide each term by 4 and simplify
4y/4 = -x/4 + 16/4
y = -(1/4)x + 4
Using the slope intercept form ( y = mx + b ) to compare.
y = -(1/4)x + 4
Slope m = -(1/4)
Now, the equation of a perpendicular line to y = -(1/4)x + 4 must have a slope that is the negative reciprocal of the original slope.
Hence, m_perpendicular will be;
m_perpendicular = -( 1 / original slope )
m_perpendicular = -( 1 / -(1/4) )
m_perpendicular = -( -4 )
m_perpendicular = 4
Therefore, the slope of a line perpendicular to the line of x + 4y = 16 is 4.

A number could also be the sum of two or more numbers. As a result, a term can be the product of two or even more quantities, at least one of which should be in logarithmic form. These same terms are recognised as log terms in such cases.A quantity can also be described as the variation between two quantities. However, if a term contains a quotient of quantities, or if at least one of the amounts can also be conveyed in log form, the term is referred to as a log term.Consider some formulas used in log.

The value of the power P is mentioned in the question; (P = 35 watt).
Thus, substitute the value of the P in teh equation;

Now, divide both sides by 42.

Taking natural log on both side;
