Please answer this question and explain the answer thank you(: ANY LINKS WILL BE REPORTED INSTANTLY!!!

Step-by-step explanation:

A function is odd if and only if f(-x) = - f(x) and is symmetric with respect to the origin.

The sine function is odd and cosine is even.

Correct option is D

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
