Larry has 4-cent stamps and 9-cent stamps, which he can combine to produce various amounts of postage. For example, he can make
Tju [1.3M]

Answer:

  • the largest number that cannot be made is 23
  • see below for an explanation

Step-by-step explanation:

<em>Why numbers greater than 23 can be made</em>

From any number that Larry can make that includes an appropriate number of stamps, Larry can ...

  • add 1 by adding 1×9 and taking away 2×4
  • add 2 by adding 2×9 and taking away 4×4
  • add 3 by adding 3×9 and taking away 6×4
  • add 4 by adding 1×4
  • add 5 by adding 4 and 1 (add 9, take away 4)
  • add 6 by adding 4 and 2 (add 2×9, take away 3×4)
  • add 7 by adding 4 and 3 (add 3×9, take away 5×4)
  • add 8 by adding 2×4
  • add 9 by adding 1×9

Clearly, for Larry to be able to continue adding any number, he must start with a number that contains at least 6×4 cents = 24 cents.

Larry can make 24 cents from 6 4-cent stamps. Using the above table, he can add any amount to that.

___

<em>Why 23 cannot be made</em>

For 23 cents, the number of stamps must include 0, 1, or 2 9-cent stamps, so there are 3 cases to try for making 23:

  • 23 cannot be made from 0 9-cent stamps because 23 is not divisible by 4
  • 23 cannot be made using 1 9-cent stamp, because 14 is not divisible by 4
  • 23 cannot be made using 2 9-cent stamps, because 5 is not divisible by 4.

Therefore, 23 cannot be made.

Suppose that $12,724 is invested at an interest rate of 6.1% per year, compounded continuously. Find the exponential function th
olchik [2.2K]

Answer:

Exponential Function: A= P* e ^ {0.061t}

Balance after

t=1 $ 13,524.32

t=2 $ 14,374.99

t=5 $ 17,261.69

t=10 $ 23,417.64

Step-by-step explanation:

Formula used to find amount in the account after time t, given the interest rate is compounded continuously

A= Pe^r^t

where: P= principal amount or amount invested

r= interest rate

t= time

A= amount after time t

in our question we are given:

P=$12,724

r= 6.1% or 0.061

A= 12724 * e ^ (^0^.^0^6^1^)^t

The above equation is exponential function that describes the amount in the account after time t in years

Now, for t = 1

A= 12724 * e ^ {0.061 * 1}

A= $ 13,524.32

t=2

A= 12724 * e ^ {0.061 * 2}

A= $ 14,374.99

t= 5

A= 12724 * e ^ {0.061 * 5}

A= $ 17,261.69

t=10

A= 12724 * e ^ {0.061 * 10}

A= $ 23,417.64
