SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define a quadratic equation that does not passes through the x-axis

When a quadratic function never crosses the x-axis, then it has no real roots or solutions. Hence, the discriminant must be negative. meaning the solutions are imaginary/complex.

Hence, the answer will be:

The function has two imaginary roots

Answer:5in

Step-by-step explanation:

1. Identify the triangle

you are given a right triangle with the hypotonus missing and are given the side lengths 3 and 4 you know the hypotonus is 5 by the 3,4,5 Pythagorean tripe, if you do not notice this it can be solved with the Pythagorean theorem a^2+b^2=c^2

2. solve (if not done with 3,4,5 triple)

3^2+4^2=c^2

9+16=c^2

25=c^2

5=c | square root both sides to cancel the square

we have the equation

i will assume

a=2

b=5

c=3

d=5

solve for x

substitute the given values

subtract 3 both sides

Divide by 2 both sides

squared both sides

the values of x are

x=-4 and x=-6

Verify each solution

For x=-4

x=-4 ------> is a solution

Verify x=-6

Is not true

therefore

x=-6 --------> is an extraneous solution

On 300 call the station first give away all three prizes to one caller.

The smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm), lowest common multiple (lcm), or smallest common multiple of two numbers a and b in mathematics and number theory. The LCM method is used to determine the least multiple of two or more numbers. Least Common Multiple is referred to as LCM. The LCM of two numbers can be divided by both of them. The LCM of 6 and 8 is 24, for instance. 24 can be divided by both 6 and 8.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other. Congruent refers to things that are exactly the same size and shape.

For these items, the word equal is frequently used in place of congruent. If two line segments are the same length, they are said to be congruent. If two angles have the same measure, they are said to be congruent. If two circles have the same diameter, they are congruent.

While equality deals with numbers, congruence deals with shapes (also known as objects). Neither "two shapes are equal" nor "two numbers are congruent" are statements that you make. If one shape can be perfectly superimposed on the other, then two shapes are said to be congruent. While equality deals with numbers, congruence deals with shapes (also known as objects).

Gestures are logical and consistent with what is being spoken. Despite not being the same, both ideas are entirely consistent. We play a game, say things we don't mean, and act contrary to our ideals. The choice is more challenging if the hip appears to be in congruence even with the

Given:

f(X) will be differentiated by chain rule.

Answer:

  no universal test point

Step-by-step explanation:

You want to know if there is or is not a universal test point that can be used for testing the shading for a linear inequality.

The purpose of a test point for the graph of an inequality is to determine whether the shaded area includes the test point or not. A single inequality will divide the universal set into two parts: one part that is the solution set, and one part that is not the solution set.

A point that is well inside the solution set (or not-a-solution set) will tell you which side of the boundary is shaded. Any point that always meets that requirement could be considered a universal test point.

The boundary point(s) between these sets may or may not be shaded, but its(their) shading, or lack of it, will not tell you which half of the universal set is the solution set. That is, any point that falls on the boundary of the solution set is not a suitable test point.

The boundary can be anywhere, so there is no single universal test point.

__

Additional comment

A set of three non-collinear points can be considered to be a universal test set. Together, they can tell you which part of the universal set is the solution set. At most, the boundary line can pass through two of them, so the third can tell you which half of the universe it lies in.

The combination of two shirts and six hats will maximize the amount of money the shopper can spend.

An inequality results from the comparison of two or more algebraic expressions using the symbols <, > ≤, or ≥. They are mathematical expressions with unequal sides.

Let's assume x is the number of shirts and y is the number of hats brought then,

Total amount spend = 21x + 16y

It is given that the total amount the shopper can spend is $140.

So, 21x + 16y ≤ 140,

As x and y are the number of shirts and the number of hats so x and y will assume positive integral values only, to find out the values of x and y plot the region 21x + 16y ≤ 140 with x ≥ 0, y ≥ 0 as shown in the graph.

From the graph, it is clear that the highest integer value which is close to the boundary of 21x + 16y ≤ 140 is x = 2 and y = 6.

The amount spend when x = 2 and y = 6 is 21(2) + 16(6) = 138

Hence, two shirts and six hats will maximize the amount of money the shopper can spend.

In Mathematics, a function simply refers to a mathematical expression which is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (Set A) to an output variable (Set B).

The non-real solutions of the polynomial expression are x = (2 + i√26)/3 and  x = (2 - i√26)/3

The equation of the polynomial expression is given as:

3x^3 + 14x^2 - 14x + 60 = 0

From the question, we have

Real solution = -6

Rewrite the above equation as

x = -6

Add 6 to both sides of the equation

So, we have

x + 6 = 0

The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0

This is represented as

3x^3 + 14x^2 - 14x + 60/x + 6

Using a graphing calculator, we have

3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10

Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula

So, we have

x = (-b ± √(b² - 4ac))/2a

This gives

x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3

So, we have

x = (4 ± √-104)/6

This gives

x = (4 ± 2√-26)/6

Divide

x = (2 ± √-26)/3

Rewrite as

x = (2 ± i√26)/3

Split

x = (2 + i√26)/3 and  x = (2 - i√26)/3

So, the conclusion is that
