X = 2 + √42,2- √42
decimal form: 8.480741, -4.480741
sorry if my answer isn't right
The answer is C because of you simplify 4/40 is 1/10
20 minutes, I believe. I’m not sure please don’t take may word for it. I would most likely need more information.
Answer:
22 years.
Step-by-step explanation:
(continued), How long will it take the 5000 Swiss Francs to accrue to 10000 = 2 x 5000 Swiss Francs.
Define T as
T = the time to double the investment.
Then, we have that
10000 = 5000(1 + 3.25%)^T
2 = (1 + 0.0325)^T
2 = (1.0325)^T
ln(2) = ln [ (1.0325)^T ]
ln(2) = T ln (1.0325)
T = ln(2) / ln(1.0325)
T = 21.6723317643
T = 22 years, rounded to the nearest year.
The 4th one because when you divide 270 by 15 you get 18 and when you also divide 135 by 7.5 you get 18 when something is proportional you get the same answer
