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:

- 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:








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

the triangle is isosceles
Answer:

Step-by-step explanation:

100 is divided by 4, so you will get 25.
25 multiply 3, you will get 75%
So, the answer is 75%.
