Consider the function y = cos(x). Which change would increase the period by a factor of 3? Multiply cos(x) by One-third Multiply cos(x) by 3. Multiply x by One-third Multiply x by 3.

its multiply x by 1/3

Step-by-step explanation:

trust

C on edg

Step-by-step explanation:

multiply x by (1/3)

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
