steve deposits $1250 in an account paying 3.4% annual interest compounded continously. how long will it take for the account bal
Tomtit [17]

Answer:

It will take 27.19 years

Step-by-step explanation:

Compound continuous interest can be calculated using the formula:

A=Pe^{rt} , where

  • A = the future value of the investment, including interest
  • P = the principal investment amount (the initial amount)
  • r = the interest rate  of interest in decimal
  • t = the time the money is invested for

∵ Steve deposits $1250 in an account

∴ P = 1250

∵ The account paying 3.4% annual interest compounded continuously

∴ r = 3.4%

- Change it to decimal by dividing it by 100

∴ r = 3.4 ÷ 100 = 0.034

∵ The account balance will reach to $3150.5

∴ A = 3150.5

- Substitute The values of A, P and r in the formula above to find t

∵ ​3150.5=1250e^{0.034t}

- Divide both sides by 1250

∴  ​2.5204=e^{0.034t}

- Insert ㏑ to both sides

∴ ​ln(2.5204)=ln[e^{0.034t}]

- Remember that ln(e^{n})=n

∵  ln(e^{0.034t})=0.034t

∴ ​ln(2.5204) = 0.034t

- Divide both sides by 0.034

∴ 27.18875 = t

∴ t ≅ 27.19

It will take 27.19 years

30. While making a dessert, Jane used
antiseptic1488 [7]

Answer:

Jane used 2/5 of a scoop more of brown sugar than she did with white sugar.

Step-by-step explanation:

If you want to find how much more something is from something else, you subtract. So, subtract 9/10-1/2. If you want to subtract, they should both have the same denominator. So, 9/10-1/2 is the same as 9/10-5/10. 9/10-5/10 is equal to 4/10 which is simplified to 2/5.

UkoKoshka [18]

Answer: The answer is Yes.

Step-by-step explanation:  Given in the question that Radric was asked to define "parallel lines" and he said that parallel lines are lines in a plane that do not have any points in common. We are to decide whether Radric's definition is valid or not.

Parallel lines are defined as lines in a plane which never meets or any two lines in a plane which do not intersect each other at any point are called parallel.

Thus, Radric's definition is valid.
