If the value the discriminant is exactly 0, what is true about the graph of the quadratic equation?

Answers

A discriminant of zero means the quadratic equation has one real root. In other words, the only part of the parabola touch the x axis is the vertex. The vertex is the bottom of the parabola.

An example is provided in the attached picture

The truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

What is a quadratic equation?

The quadratic equation is defined as a function containing the highest power of a variable is two.

When discriminant D of a quadratic equation,

D = 0

Roots are equal and real

D > 0

Roots are real and different

D < 0

Roots have not existed.

When the discriminant is zero, there is only one real root to the quadratic equation. In other words, only the vertex of the parabola connects the x-axis. The vertex is the parabola's base.

Therefore, the truth about the graph of the quadratic equation would be the vertex of the parabola connects the x-axis when the value of the discriminant is exactly zero.

Answers

Answer:

Part A - Yes; y=5/3w        Part B - No; e=h+2

Step-by-step explanation:

The tables show the numbers of white and yellow flowers Cara and Hector used in 5 different arrangements.

Cara’s Flower Arrangements            Proportional

White 3 6 9 12 15

Yellow 5 10 15 20 25

Hector’s Flower Arrangements          Not Proportional

White 4 8 12 16 20

Yellow 6 10 14 18 22

Part A

Are the numbers of white and yellow flowers in Cara’s arrangements proportional?

Which equation relates the number of white flowers, w, to the number of yellow flowers, y?

Yes; y=3/5w

Yes; y=5/3w CORRECT ANSWER

No; y=3w+5w

No; y=5+3w

Part B

Are the numbers of white and yellow flowers in Hector’s arrangements proportional?

Which equation relates the number of white flowers, h, to the number of yellow flowers, e?

Yes; e=3/2h

Yes; e=2/3h

No; e=h+2 CORRECT ANSWER

No; e=h−2

They are correct because Part A is 1.666667  thats more than 1 so it cant be the first, and Part B, its the White flowers plus 2 to be Yellow flowers, not -.

Following are the solution to the given question:

Using the proportionate connection theory to model these two tables, we may conclude the first table is proportionate whereas the second is not.Clara's configuration:

                   [tex]\bold{White (w) }\\\\\bold{Yellow (y)}[/tex]

To determine whether a relationship is proportionate, perform the following tests:

                    [tex]\bold{y = kw } \\\\\bold{5 = 3k}[/tex]

Yes, there seems to be a proportional relationship. Hector's set-up is as follows:

                  [tex]\bold{White (h) }\\\\\bold{Yellow (e)}\\\\[/tex]

The number of yellow flowers always out-numbers the number of white blooms by a factor of 2. As a result, the relationship could be modeled as follows;

               [tex]\to \bold{e = h + 2}[/tex]

As a result, the relationship is not proportionate.

Suppose that under your health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay. You get sick and are hospitalized for 4 days, and the bill (after your insurance discounts are applied) comes to $6,250. How much of that hospital bill will you have to pay yourself?

Answers

Answer:

$4900

Step-by-step explanation:

It is given that,

According to health insurance policy, hospital expenses are subject to a $750 deductible and $150 per day copay.

If a person hospitalized for 4 days, it would mean that charges will be ($150 × 4 = $600 per day).

Total amount given by insurance policy = $750 + $600 = $1350

The bill for 4 days come out to be $6,250.

The person have to pay ($6,250-$1350) = $4900 itself.

If a translation is described as (x -5, y), how has the original image changed?

Answers

Answer:

It moves the x value 5 units to the left.

Step-by-step explanation:

"x - 5" means that we are subtracting 5 to whatever x value we are given. The "y" value doesn't change.

Since we are subtracting to the x value, we are going to move left 5 units.

Let's say we had the point (5, 5).

If we use the translation rule;

(5 - 5, 5)

(0, 5)

We moved the x value 5 units to the left.

Translation involves changing the position of a shape or line or point.

The value of k is -3

The given parameter is:

[tex]\mathbf{g(x) = f(x) + k}[/tex]

From the attached graph, we can see that the line of f(x) is shifted down by 3 units to form g(x).

This means that:

[tex]\mathbf{g(x) = f(x) - 3}[/tex]

By comparing: [tex]\mathbf{g(x) = f(x) - 3}[/tex] and [tex]\mathbf{g(x) = f(x) + k}[/tex]

We have:
