Area of the circle S be 16π square. millimeter
What is an area of circle ?
The area of a circle is the space the circle occupies in the two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr2, where r is the radius of the circle. A unit area is a unit square. Examples: m2, cm2, in2, etc. Circle area = π[tex]r^{2}[/tex]in square units (Pi)π = 22/7 or 3.14. Pi (π) is the ratio of the circumference to the diameter of any circle. This is a special mathematical constant.
It is given that the radius of circle S is half the radius of circle L and the radius of circle L is 8 millimeters.
Radius of the circle S = 8/2 = 4 millimeters
Area of the circle S = π[tex]r^{2}[/tex] = π[tex](4)^{2}[/tex] = 16π square. millimeter
Therefore, area of the circle S be 16π square. millimeter

The inequality shown by the graph in the question, found by finding the equation for the line of the inequality and taking note of the dashed line and the shaded region, is; y > 2·x - 4
What is an inequality?An equality is a comparison between two expressions that have different values, by joining them with the use of symbols including '<', '≤', '≥', '>', '≠'
Two points on the graph that can be used to find the equation of the line of the inequality are;
(4, 4), and (2, 0)The slope, m, of the line found from the above two points on the line is therefore;
m = (0 - 4)/(2 - 4) = 2
The equation of the line in point-slope form is therefore;
y - 0 = 2·(x - 2) = 2·x - 4
The equation of the line of the inequality is therefore;

What is the slope of a line parallel to the line whose equation is 12x+2y=24Fully simplify your answer.
Answer:
The slope is -6
Step-by-step explanation:
12x+2y=24
We want to find the slope of a line that is parallel to this line.
Parallel lines have the same slope, so we need to find the slope of this line.
We can get this equation in slope intercept form to find the slope
y = mx+b where m is the slope
Subtract 12x from each side
2y = -12x+24
Divide each side by 2
y = -12x/2 +24/2
y = -6x+12
The slope is -6
Write an equation in slope-intercept form of the line that passes through the points (2, 15) and (5, 21).
The equation of the line that passes through the points (2, 15) and (5, 21) is y = 2x + 11
The coordinates of the first point = (2, 15)
The coordinates of the second point = (5, 21)
The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the values in the equation
The slope of the line = (21-15) / (5-2)
= 6 / 3
= 2
The slope intercept form is
y = mx + b
Substitute the values
15 = 2(2) + b
15 = 4 + b
b = 15 - 4
b = 11
Substitute the values in the equation
y = 2x + 11
Therefore, the equation of the line in slope intercept form is y = 2x + 11

What is displacement?
Displacement is defined as a change in an object's position. An object's displacement is defined as how far it has moved from its starting point. The dependent variable in the displacement time graph is displacement, which is represented on the y-axis, and the independent variable is time, which is represented on the x-axis. Position-time graphs are another name for displacement time graphs.
The displacement curve is given for 0 ≤ t ≤ 18.
We need to find the total distance of the curve, it will be the positive sum of all displacements.
So, total distance = (7-0) + (3-0) + (2+3) + (2+4) + (7-4)

What does a simple interest mean?Simple interest is calculated based on the principal of a loan or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay interest on interest that has already accrued.
How is a simple interest calculated?To calculate simple interest, multiply the principal sum by the time period, interest rate, and time period. Simple interest is calculated as follows: "Simple Interest = Principal x Interest Rate x Time." This equation provides the simplest method for calculating interest.
