The principal P is borrowed at a simple interest rate r for a period of time t. Find the​ loan's future value​ A, or the total a
Julli [10]

The​ loan's future value​ A, or the total amount due at time t is $1105.

Given, P = ​$1000​, r = 3.5​%, t = 3 months.

We need to find the loan's future value A.

<h3>What is Simple interest?</h3>

Simple interest is computed on the principal amount of a loan or the first deposit in a savings account. Simple interest does not compound, therefore an account holder will only get interest on the principal, and a borrower will never have to pay interest on previously collected interest.

We know that, Simple Interest=\frac{P\times\ T \times\ R }{100}

Now, Simple Interest=\frac{1000\times3\times3.5}{100\times12}

=\frac{10,500}{100} =105

As we know, Amount=Principal+Simple Interest

=1000+105=1105

Hence, the​ loan's future value​ A, or the total amount due at time t is $1105.

(a)

y=-5x^2+21x-3

for x = 2:

y=-5(2)^2+21(2)-3=-20+42-3=19

for x = 5

y=-5(5)^2+21(5)-3=-125+105-3=-23

(b)

The graph is:

(c)

Using the graph:

\begin{gathered} x=1.8,y=18.6 \\ x=0.548,y=7 \\ x=3.65,y=7 \end{gathered}\begin{gathered} x=1.8 \\ y=-5(1.8)^2+21(1.8)-3=-16.2+37.8-3=18.6 \end{gathered}\begin{gathered} y=7 \\ -5x^2+21x-3=7 \\ -5x^2+21x-10=0 \end{gathered}

Using the quadratic formula:

\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ x=\frac{-21\pm\sqrt[]{21^2-4(-5)(-10)}}{2(-5)} \\ x=\frac{-21\pm\sqrt[]{241}}{-10} \\ x=0.54758 \\ or \\ x=3.6524 \end{gathered}
