The magnitude of Ū is 8, and its direction angle is 320°.
The magnitude of w is 6, and its direction angle is 100°.
Find the magnitude and direction angle of ū+ w.

The magnitude of ū+w

The direction angle of ū+w is

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

a and c

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
