Neporo4naja [7]3 years ago

4 0

Answer:

No real roots

Step-by-step explanation:

Given

$6x^2 + 6x + 3 = 0$

Required

The number of solution

The discriminant (d) for $ax^2 + bx + c = 0$ is:

$d = b^2 - 4ac$

So, we have:

$d = 6^2 - 4*6*3$

$d = 36 - 72$

$d = -36$

<em>Since </em> $d$ <em>, then the equation has no real roots</em>

attashe74 [19]

<h2>The bond will be worth in total after 10 years is =$1,950</h2>

Step-by-step explanation:

Given,

Nora invested $1,500 in at a bond simple interest rate of 3%

here P= $1500 R= 3% and t = 10year

Simple interest(I) = $\frac{P\times R \times t }{100}$

=$ $\frac{1500\times 3 \times 10}{100}$

=$ 450

<h3>The bond will be worth in total after 10 years is = $1,500+ $450</h3><h3> =$1,950</h3>
