Answer:
20 years.
Step-by-step explanation:
We have been given a formula , which represents the value of an investment A (in dollars) after t years.
Substitute the given values:
Let us solve for k.
Take natural log of both sides:
Using property , we will get:
We know that , so
Dividing both sides by 1000, we will get:
Take natural log of both sides:
Divide both sides by :
Therefore, it will take 20 years for the investment to be $9,000.
Answer: 3/6 + 4/6
Step-by-step explanation:
So the key to this is you can only add fractions with the same denominator. As you can see from this question these denominators (2 and 3) are not the same so we need to change that. We can usually find a common denominator between the numbers but to save time the smallest number that both 2 and 3 go into is 6. so 1/2 becomes 3/6 because 1/2=3/6. And 2/3 becomes 4/6 because 4/6=2/3. Since that's true we can add both 3/6 and 4/6. So when adding fractions remember only add NUMERATORS do not add DENOMINATORS. so 3/6 and 4/6 = 7/6 NOT 7/12.
