In order to find the quadratic equation, let's use the standard form of a quadratic equation:

Using the point (0, 2) from the table, we have:

Now, using the points (-1, -2) and (1, 22):

Adding both equations, we can solve for a:

Therefore the equation is y = 8x² + 12x + 2

A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

As per the given linear equation, y = 2/3x + 1

To be a point of its solution the point must satisfy the given equation.

Substitute (6,5)

5 = (2/3)6 + 1

5 = 2(2) + 1 = 5

Therefore, the (6,5) is the solution of the equation.

Substitute,(9,8)

(2/3)9 + 1 = 7

8 ≠ 7

So,(9,8) is not the solution of the equation.

Hence "A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution".

The ladder will not reach a window that is 21.5 feet above the ground if the length of the ladder is 25 feet.

It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.

From the data:

The right angle triangle can be drawn:

From the diagram:

Applying Pythagoras' theorem:

BC² = AB² +  AC²

25² = 15² +  AC²

After solving

AC = 20 feet

AC < 21.5 feet

Thus, the ladder will not reach a window that is 21.5 feet above the ground if the length of the ladder is 25 feet.

The equation that could model the given situation is y = -x + 30.25. The correct option is B. y = -x + 30.25

From the question, we are to determine the equation that could model the given situation

The perimeter, P, of a rectangle is given by the formula,

P = 2(l + w)

Where P is the perimeter

l is the length

and w is the width

From the given information,

The perimeter of a rectangular room is 60.5 feet.

∴ P = 60.5 feet

Also,

x is the width of the room and y is the length of the room

That is,

l = y

and

w = x

Thus,

The equation becomes

60.5 = 2(y + x)

2(y + x) = 60.5

Divide through by 2

y + x = 30.25

y = -x + 30.25

Hence,

y = -x + 30.25 is the equation that might be used to model the circumstance.

1. each ounce of fruit will supply zero units of protein, 3 units of carbohydrates, 2 units of fat and will contain 20 calories

2. each ounce of nuts will supply 3 units of protein, 2 units of carbohydrates and 4 units of fat, and will contain 50 calories

3. Every package must provide at least 9 units of protein, at least 18 carbohydrates, and no more than 22 units of fat

To get at least 9 units of protein, we take at least 3 ounces of nut

3 ounces of nut will give 3 times each unit, and they are as follows

Another restriction is no more than 22 units of fat and we have 12 already remaining 10 units of fat

fruits has lesser calories hence we use it to get the required fats

10 units of fat ÷  2 units of fat in fruit = 5

5 ounces of fruit will give 5 times each unit, and they are as follows

Combining 3 ounces of nut and 5 ounces of fruit will give

The Bank discount and proceeds of the given information is:

$2365.27 and $47634.73 respectively.

Given the face value is $50,000

Discount rate = 13%

No.of term days = April 5 to August 14

= 131 days.

Bank discount = ?

Proceeds = ?

First calculate the bank discount using the formula:

Bank discount = face value × discount rate × time

Bank discount = $50,000 × 0.13 × 131/360

= 50,000×0.13×0.36388

= $2365.27

now calculate the proceeds using the formula :

Proceeds = face value - bank discount

= 50,000 - 2365.27

= $47634.73

Hence the bank discount and proceeds are $2365.27 and $47634.73 respectively.

The inverse of the function → f(x) = [tex]\sqrt{11x+12}[/tex] is

f⁻¹(x) = (x² - 12)/11

We have -

y = f(x) = [tex]\sqrt{11x+12}[/tex]

We have to find its inverse function.

Inverse of a function can be calculated by following the steps mentioned below -

Step 1 -  Replace 'y' with 'x' and vice - versa.

Step 2 - Rewrite the equation by solving for 'y'.

Step 3 - Replace 'y' with f⁻¹(x).

According to the question -

y = f(x) = [tex]\sqrt{11x+12}[/tex]

x = [tex]\sqrt{11y+12}[/tex]

x² = 11y + 12

x² - 12 = 11y

y = (x² - 12)/11

f⁻¹(x) = (x² - 12)/11

Therefore, the inverse of the function → f(x) = [tex]\sqrt{11x+12}[/tex] is

real number can be a complex number but a complex number can not be a real number, verified.

the lengths of the complex number and its conjugate are equal but the converse is not necessarily true., verified.

Not all complex numbers are real numbers, despite the fact that every complex number is a real number.

In fact, determining whether the complex number z = a + bi is real is one of the complex conjugate's most useful applications. If and only if z = a + 0i, a complex number is real. In other words, a complex number is real if it contains an imaginary part.

Mathematical proof:

Let z = a+bi, where a and b = real numbers.

Let z* =complex conjugate of z.

Then the magnitude (absolute value) of z is:

|z| = √(a²+b²).

And the value of z* is:

|z*| = √[a²+(-b)²] = √(a²+b²).

So |z| = |z*|.

This Completes the Proof.
