If the discriminant, b^2-4ac is ___, a quadratic will have two real roots, two points of intersection with the x-axis.

den301095 [7]

If the discriminant, b² - 4ac is positive

<h3>How to complete the statement?</h3>

From the question, we have the following equation of discriminant

The discriminant (d) is calculated as

d = b² - 4ac

The solutions of a quadratic equation are dependent on the following conditions

If d = 0, the quadratic equation has 1 real solution
If d < 0, the quadratic equation has imaginary solutions
If d > 0, the quadratic equation has 2 different real solutions

This means that "d > 0, the quadratic equation has 2 different real solutions" implies that the discriminant is positive

Hence, the complete statement is (b) positive

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally. How long will each k

Harman [31]

Answer:

Each knight will guard 288 minutes in one day.

Step-by-step explanation:

Given:

A castle has to be guarded 24 hours a day. Five knights are ordered to split each day's guard duty equally.

Now, to find the minutes will each night spend on guard duty in one day.

As, in 1 hour there are 60 minutes.

Thus, in 24 hour there are 60 × 24 = 1440 minutes.

Total minutes for guarding = 1440 minutes.

So, there are knights ordered for guarding are = 5.

And each day's guard duty equally.

Now, to get the minutes will each night spend on guard duty in one day we divide the total minutes for guarding by number of knights that is 5:

$1440\div5$

$=288\ minutes.$

Therefore, each knight will guard 288 minutes in one day.
