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

The elements in the set A'∩B is { z } .

Set theory is a branch of mathematical logic that studies sets, which are essentially collections of objects.

Given universal set U = {q, r, s, t, u, v, w, x, y, z}

set A = {q, s, u, w, y}

∴A' = {r, t, v, x, z}

set B =  {q, s, y, z}

Now A'∩B = { z }

Hence the elements in the set A'∩B is { z } .

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

The first step to find the value of 'x' in this expression is to calculate the product with the parenthesis term:

Then, we need to isolate in one side of the equation the terms with the variable 'x', and in the other side the terms without the variable 'x'. Then, we can calculate the value of x:

So the value of x in this expression is -7

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.

The mapping diagram above does not represent a function since

for each number in Set A (the input) where there are multiple mappings

from Set B (the output).

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).

Based on the mapping diagram shown above, we can reasonably infer and logically deduce that Set A with inputs (-4, 8), (1, 8) and (1, -3) are ordered pairs which does not represent a function because they indicate multiple mappings in Set B (the output).

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

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

The constant of proportionality for the equation y = 2x is k = 2.

The number of pieces of fruit the monkey can eat is two times the amount of time the monkey takes.

The equation y = 2x can be used to represent a monkey eating 24 pieces of fruit in 12 hours.

The constant of proportionality, which is a fixed value that represents the rate at which two or more ratios rise or decrease, is used to compare them. The result of dividing the denominator by the numerator when a ratio is expressed as a fraction is the constant of proportionality.

When a ratio is expressed as a fraction, the constant of proportionality is found by dividing the denominator by the numerator. The constant of proportionality, k, can be calculated from the equation if x is the ratio's numerator and y is its denominator.

k = y/x

Therefore, the constant of proportionality in this case is:

y = 2x

k = y/x = 2

The constant of proportionality in this case represents that the number of pieces of fruit a monkey eats is two times the amount of time the monkey takes.

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.
