The savings in a bank account can be modeled using S = 1250e^0.45t, where t is the number of years the
morpeh [17]

Using the given exponential function, it is found that it will take 1.5 years for the  amount of savings to double from the initial amount deposited of $1250.

<h3>Exponential function:</h3>

The <em>exponential function</em> that models the savings in the bank account is given by:

S(t) = 1250e^{0.45t}

  • In which t is the time in years that the money has been in the account.

The time to double from the initial amount deposited of $1250 is t for which S(t) = 2(1250) = 2500, hence:

S(t) = 1250e^{0.45t}

2500 = 1250e^{0.45t}

e^{0.45t} = \frac{2500}{1250}

e^{0.45t} = 2

\ln{e^{0.45t}} = \ln{2}

0.45t = \ln{2}

t = \frac{\ln{2}}{0.45}

t = 1.5

It will take 1.5 years for the  amount of savings to double from the initial amount deposited of $1250.

Answer:

Radius of park r = 282.04 ft (Approx)

Step-by-step explanation:

Given:

Number of people = 50,000

Each person needs area = 5 ft²

Park's is in shape of circle

Find:

Radius of park r

Computation:

Total area required = 50,000 x 5

Total area required = 250,000 ft²

Area of circular park = Total area required

πr² = 250,000

(22/7)r² = 250,000

r² = 79545.4545

r = 282.04 ft

Radius of park r = 282.04 ft (Approx)
