Answer:
Part A: The graph of given inequality is shown below.
Part B: The point (4,6) is not a solution of given system of inequalities.
Step-by-step explanation:
Part A:
The given inequalities are
The related equation of given inequalities are
Put x=0, to find the y-intercepts.
Put y=0, to find the x-intercepts.
The x and y-intercepts of first line are (0,3) and (-1.5,0) respectively. The x and y-intercepts of second line are (0,-4) and (-2.667,0) respectively.
Check the given inequality by (0,0).
This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.
This statement is false. It means (0,0) is not the solution of this inequality and the shaded region is opposite side of the origin.
The graph of given inequalities is shown below.
Part B:
We have to check whether (4,6) is a solution of the system of inequality or not.
Check the given inequality for the point (4,6).
This statement is false. It means (4,6) is not the solution of given system of inequalities.
The earth is 40000 kilometers around. There is no need to round off because the circumference already contains significant figures.
How do I calculate a circle's circumference?
A circle's diameter is multiplied by to determine its circumference (pi). You can also determine the circumference by multiplying 2radius by pi (=3.14).
Given: theta angle (central) = 7.2°; arc length S = 800 km
This indicates that an 800 km long arc is extending a circle with a 7.2° center angle ( earth in this case).
By definition, "An arc's length is a portion of a circle's diameter."
Therefore, we must first establish what percentage of the circle the specified arc length represents.
360° is a complete circle.
Thus, the fraction equals 7.2°/360°, or 1/50.
As a result, the stated arc length (800km) with a 7.2° central angle is 1/50th of the entire circle.
Thus, the whole circumference is 800 x 50, or 40000 km.
Alternately, you can calculate circumference using the formula below:
360° center angle x arc length as the circumference (theta)
Values substituted: circumference 800 = 360° 7.2°
circumference = 360°, 800°, and 7.2°, or 40000 kilometers
Therefore, the earth is 40000 kilometers around. There is no need to round off because the circumference already contains significant figures.
