Determine whether the statement is always, sometimes, or never true:

Mathematics
1 answer:
Rzqust [24]4 years ago

Answer:

The statement 'A quadratic function with real coefficients has real roots' is some times true and some times false.

Step-by-step explanation:

The quadratic function in the form ax² + bx + c = 0, has real roots when the discriminant, given by D = b² - 4ac is greater than or equal to zero.

And the equation has imaginary roots when D = b² - 4ac is less than zero.

So, even a quadratic equation has real coefficients can have non-real roots depending on the value of the discriminant.  

Hence, the statement 'A quadratic function with real coefficients has real roots' is some times true and some times false. (Answer)

Suppose yoko borrows $3500 at an interest rate of 4% compounded each year Find the amount owed at the end of 1 year
olchik [2.2K]

Amount owed at the end of 1 year is 3640

<h3><u>Solution:</u></h3>

Given that yoko borrows $3500.

Rate of interest charged is 4% compounded each year

Need to determine amount owed at the end of 1 year.

In our case :

Borrowed Amount that is principal P = $3500

Rate of interest r = 4%

Duration = 1 year and as it is compounded yearly, number of times interest calculated in 1 year n = 1

<em><u>Formula for Amount of compounded yearly is as follows:</u></em>

A=p\left(1+\frac{r}{100}\right)^{n}

Where "p" is the principal

"r" is the rate of interest

"n" is the number of years

Substituting the values in above formula we get

\mathrm{A}=3500\left(1+\frac{4}{100}\right)^{1}

\begin{array}{l}{A=\frac{3500 \times 104}{100}} \\\\ {A=35 \times 104} \\\\ {A=3640}\end{array}

Hence amount owed at the end of 1 year is 3640
