Milton has his money invested in a stock portfolio. The value, v(x), of his portfolio can be modeled with the function v(x)=30,000(0.78)^x, where x is the number of years since he made his investment. Which statement describes the rate of change of the value of his portfolio? (1) It decreases 78% per year. (2) It decreases 22% per year. (3) It increases 78% per year. (4) It increases 22% per year.

Answer 2

Step-by-step explanation:

If you do 30,000(.78) in a calculator then you end up with 23400. Decreasing by 78% is to much of a decrease and it definitely did not increase.

answer: procent 54 wynosi 33,33%

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
