Answer:

5.0 days

Step-by-step explanation:

From the question given above, the following data were obtained:

Initial mass (N₀) = 46 g

Constant (K) = 0.1374 /day

Half life (t₁/₂) =?

The half life (t₁/₂) is related to the decay constant according to the following equation:

t₁/₂ = 0.693 / K

With the above equation, we can obtain the half-life of the substance as follow:

Constant (K) = 0.1374 /day

Half life (t₁/₂) =?

t₁/₂ = 0.693 / K

t₁/₂ = 0.693 / 0.1374

t₁/₂ = 5.04 ≈ 5.0 days

Thus, the half-life of the substance is 5.0 days

Anna starts a fixed deposit with $178000, the bank offers 9.5% per year simple interest for 8 months. she has the option of rest
soldier1979 [14.2K]

Using simple interest, we have that:

A) The interest due after 8 months is $11,272.33.

B) The total value of the investment will be of $189,986.24.

The amount of interest earning using <em>simple interest</em>, after <u>t years</u>, with an <u>yearly interest rate of i</u> and an <u>initial investment of P</u> is given by:

E = Pit

In this problem:

  • Deposit of $178,000, hence P = 178000.
  • Interest rate of 9.5% per year, hence i = 0.095.
  • 8 months, the time is in years, hence t = \frac{8}{12} = \frac{2}{3}

Item a:

E = Pit

E = 178000(0.095)\frac{2}{3} = 11272.33

The interest due after 8 months is $11,272.33.

Item b:

For the second interest, we consider P = 11272.33, hence:

E_2 = Pit

E_2 = 11272.33(0.095)\frac{2}{3} = 713.91

The total value will be composed by:

  • The initial deposit of $178,000.
  • The first interest of $11,272.33.
  • The second interest of $713,91.

Hence, it will be:

T = 178000 + 11272.33 + 713.91 = 189986.24

The total value of the investment will be of $189,986.24.
