Answer:
1 and 2
Step-by-step explanation:
The vertical asymptote is r = 0.
The intensity is undefined at the source.
The horizontal asymptote is I = 0.
As the distance from the source increases, the intensity goes to zero.
The intensity decreases as the distance increases.
Mean = 74.4
Median = 83.5
Mode = 93
Answer:
323.11 ft
Step-by-step explanation:
The ellipse has two different axes which are the major and the minor axes. The major axis is longer than the minor axis. Therefore,
Major axis length = 2*a = 380; a = 380/2 = 190 ft
Minor axis length = 2*b = 200; b = 200/2 = 100 ft
To calculate the distance between Walter and Barbara (2*c), we consider the lengths a, b, and c as a right-angle triangle. If we use the Pythagoras theorem, we have:
c^2 = a^2 - b^2 = 190^2 - 100^2 = 26100
c = sqrt(26100) = 161.55 ft
Therefore, the distance between Walter and Barbara = 2*161.55 = 323.11 ft
We can solve this system of equation using substitution. We can start by getting the value of x from the equation x - 2y = 14. We can get the value of x here by adding 2y to each side, meaning that x = 2y + 14. Now we can substitute this into our other equation.
x - 3y = 9
(2y + 14) + 3y =9
5y + 14 = 9
5y - 14 + 14 = 9 - 14
5y = -5
y = -1.
Since the only answer that has y as negative one is C., that means that the answer is C., (12, -1).
