Answer:
Option D is correct
The initial value is 2
Step-by-step explanation:
The equation of line passes through the origin is represented by:
y = mx where m is the slope or unit rate .
Direct Proportionality says that:
if then the equation of the form is y = kx where k is the constant of proportionality.
Given the equation:
Then by definition:
m = 2
⇒ Slope on the line is 2.
⇒ the unit rate is 2.
Also, the constant of proportionality is 2.
Therefore, the statement which is not true for the equation y=2x represents a set of data is: The initial value is 2
Answer:
The cities are approximately 1452 km apart
Step-by-step explanation:
The two cities are on the same Longitude 90°W therefore the distance between them is on a great circle
Latitude of the first city = 23°N
Latitude of the second city = 36° N
Because their latitude are on the same polar axis, we subtract to get the angular difference
Angular Difference = 36 -23 =13°
where
The cities are approximately 1452 km apart
