Rohan invested in a precious mineral. the value of the mineral tends to increase by about 9% per year. he invests $12,000 in 2018. how much more will his investment be worth by 2025? enter your answer in the box. round to the nearest whole dollar.

$9,936.47

Step-by-step explanation:

Similarly to the other problem I helped you with we have:

Where A is amount, r is rate and t is time.

In this case A=12000, r=9%=0.09 and 9% in decimals is 0.09 (9÷100=0.09), and t=7 since 2025 -2018 = 7 years. So how much is this investment worth in 7 years? Let's plug those values in and we obtain:

So the investment will be worth $21,936.47.  Now we must calculate how much more will this precious mineral be worth so we get the difference of the final amount and the initial amount the mineral was worth and so:

And so the mineral will be worth $9,936.47 more than it originally was worth after 7 years.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

the square root of what number? if you add that, then someone will probably answer the question.
