Find the magnitude and direction of the vector <3,9>

9.49 units at an angle of 71.6° with the horizontal

Step-by-step explanation:

Magnitude: [x^2 + y^2]^(1/2)

(3^2 + 9^2)^(1/2)

(90)^(1/2) = 3root(10) = 9.49

Direction:

Angle with the horizontal: tan inverse (y/x)

tan inverse of (9/3)

tan inverse of 3 = 71.6°

idk

step-by-step explanation:

use that smart brain

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
