Let's talk about vector spaces! determine whether the set 0} with the standard operations in r2 is a vector space. s {(z, y)x, ye r, x > 0, y

step-by-step explanation:

their are no angles. sorry cant .

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
