Answer:
8 dollars
Step-by-step explanation:
Define the variable X as:
X = Original Price of the Socks, in units dollars
Then,
(X + 24)(100% - 25%) = 24
(X + 24)(0.75) = 24
X = (24/0.75) - 24 = 8 dollars.
Answer:
False
Step-by-step explanation:
The short reason the statement is false is, "it depends on what you mean by <em>direction angle</em>".
The long reason the statement is false is that "direction angle" sometimes refers to a navigation direction that is specified in terms of compass directions. For example, you might have N20°E, or S80°E. The angle measure in such directions is 0 to 90°. It does not take on a negative value when the direction is expressed in the standard form, an angle east or west from north or south.
An arbitrary vector is an expression that has a magnitude and direction. Such a quantity can have either or both values be positive or negative and of <em>any magnitude</em>. There is no reason for direction to be restricted to values in the range ±90°.
The correct answer would be -1/8
