Which number is the discriminant of a quadratic equation that has no solution?

Mathematics
1 answer:
harkovskaia [24]3 years ago
8 0

Answer:

-4

Step-by-step explanation:

If the discriminant is negative there can be no real number solution because the square root of a negative number does not exist (in real numbers).

In the Quadratic Formula, if  b^2-4ac  is negative, then you can't find  \sqrt{b^2-4ac}.

Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.What amount of change did Chloe
KatRina [158]

Answer:

Chloe received $11 as change if she gave the clerk $50

Step-by-step explanation:

We are given that Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.

Cost of sweater = $24

Cost of shirt =\frac{5}{8} \times 24 = 15

So, Total cost of shirt and sweater = 24+15=39

Now She gave $50 to clerk

So, Change received by her = 50-39=11

So, Chloe received $11 as change if she gave the clerk $50

A long spring is attached to a wall at one end. A pulse is sent down the spring. When the pulse reaches the wall it bounces back
Vika [28.1K]

It is given that at the moment the first pulse reaches the wall, a second pulse is sent down the spring. Now, when the two pulses meet they will be subject to the principle of superposition and as one is upside down (the reflected pulse) and the other is up (the second pulse), there will be a nullifying effect and the spring will appear straight for that split moment. Thus we can say that there will be a destructive interference where one pulse will destroy the other or in other words nullify the other's existence. After that moment the pulses will move towards their respective ends as if nothing happened.

Hence, Option B is the correct option.
