Make a vector diagram that illustrates the velocity of an airplane heading east at 400 knots. Illustrate a wind velocity of 50 knots blowing toward the northeast. If the airplane encounters the wind, illustrates its resultant velocity. Calculate the resultant speed and direction of the airplane.

the circle one

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
