SOLUTION:

Step 1:

In this question, we are given the following:

Can you give me two examples of an absolute value parent function?

Step 2:

What is the parent function for absolute value?

An absolute value function is a function that contains an algebraic expression within absolute value symbols. Recall that the absolute value of a number is its distance from 0 on the number line.

Examples include:

1. The absolute value parent function, written as: f(x)=| x |, is defined as:f(x)={x if x>00 if x=0−x if x<0.

, is defined as:

2. The second example of absolute value function is:

Scale factor means ratio of the sides of the triangle then the measures of the indicated sides, and the scale factor of CB and AB exists ΔDEF - ΔABC; x = 1.5; CB = 3.9; AB = 3.

A scale factor is the amount by which an object is multiplied to produce a second object of different size but with the same appearance. The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Each pair of given polygons are similar.

Similarity statement for the given polygons:

In ΔDEF and ΔABC,

∠D = ∠A (Angle)

∠E = ∠B  (Angle)

Therefore, ΔDEF  ΔABC (by AA similarity)

If two triangles are similar, then their sides are proportional.

[tex]$\Rightarrow \frac{D F}{A C}=\frac{D E}{A B}$[/tex]

[tex]$\Rightarrow \frac{2.4}{3.6}=\frac{2}{2 x}$[/tex]

By using cross multiplication, we get

⇒ 2.4 × 2x = 2 × 3.6

simplifying the above equation, we get

⇒ 4.8x = 7.2

⇒ x = 1.5

Therefore, the value of x = 1.5.

Substitute x = 1.5 in CB and AB,

CB = 3x – 0.6 = 3(1.5) – 0.6 = 3.9

AB = 2x = 2(1.5) = 3

Scale factor means ratio of the sides of the triangle.

⇒ DF/AC = 2.4/3.6 = 2/3

Therefore, the correct answer is option a) ΔDEF - ΔABC; x = 1.5; CB = 3.9; AB = 3.

The complete question is:

Each pair of polygons is similar. Write a similarity statement for the polygons. Then, find the measure of x, the measures of the indicated sides, and the scale factor.

[tex]$\overline{C B}$[/tex] and [tex]$\overline{A B}$[/tex]

a) ΔDEF -  ΔABC; x = 1.5; CB = 3.9; AB = 3;

b) ΔDEF - ΔCBA; x=3 ; C B=3 ; A B=3.9 ; 2/3

c) ΔDEF -  ΔCBA; x=1 ; C B=3.9 ; A B=3 ; 2/3

d) ΔDEF -  ΔABC; x=1.5 ; C B=3 ; A B=3.9 ; 3/2

1. The simple interest rate is 80%

2. The interest earned on the account after 10 years is $75

Simple interest can be defined as a mathematical or arithmetic method of calculating the charge of interest on a given loan.

The formula for simple interest is expressed as;

I = PRT/100

Where;

From the information given, we are to determine the interest rate, R

Substitute the values into the formula, we have;

320 = 200 × R × 2/100

Now, cross multiply, we have;

320(100) = 400R

Find the product of the values

400R = 32000

Divide both sides by the coefficient of the interest rate, we get

R = 32000/400

Find the quotient

R = 80%

If the interest for 2 years is $15

Then in 10 years = $x

cross multiply

x = 150/2

Find the quotient

x = $75

Hence, the rate is 80%

The student that has the higher standing in the class is Jill

The given parameters are:

Number of students = 200

Jill's position =80th

Nathan's position = Percentile rank  of 80

The above means that

Nathan's position = 80 percentage of the number of students in the class

Substitute the known values in the above equation

So, we have the following equation

Nathan's position = 80 percentage of 200

Rewrite as

Nathan's position = 80 percentage * 200

Express as percentage

Nathan's position = 80% * 200

Express 80% as decimal

Nathan's position = 0.80 * 200

Demonstrating that the limit doesn't exist

What is Limits?

The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are used to define continuity, derivatives, and integrals.

The limit exists only if the value of the limit along every direction that leads to (1,1) is same.

So by calculating,

                             lim   xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2

                             x->1

calculating the limit along the line x = 1

Similarly,

              lim   xy -x-y + 1 / x^2 + y^2 - 2x - 2y + 2

             x->1

calculating the limit along the line y = 1

And the last limit you calculated is along line y=x.

To answer your question, the calculation of the limit along y=1 would not have been necessary. It is sufficient to demonstrate the absence of a limit by giving just two cases in which it appears to vary along several directions.

It should be noted that when the graph of a relationship is a line that passes through the origin, then it is proportional.

A connection is proportional if its graph is a line that goes through the origin. The ratio is not proportionate if it is not a line or ray that doesn't accomplish this. K = y/x is the equation for the proportionality constant. The equation for the slope of a straight line with respect to the origin is the same as this.

Calculate the restaurant's scale drawing area. Such is:

([tex]\frac{1inch}{12feet}[/tex]) ² = [tex]\frac{1inch^{2} }{144feet^{2} } }[/tex]

We can set up this percentage and then solve for "x" to determine the precise location of the restaurant because the restaurant's location is indicated on the map.

By solving the equation, we get the cost of sheet metal =$20 per sq. feet

What is an equation?

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.

Given equation 8.2x-3.7x = 90

The absolute value function as piecewise function of y = -3(x + 24)/4 and y = 3(x - 38)/4

The absolute value function is commonly understood as a function providing the distance the number is from zero on a number line.

y = 3/4|x-6|-8

y = 3/4(-(x-6))-8

y= 3/4( -x + 6) -8

y = 3(-x + 6 - 32)/4

4y = -3x - 24

y = -3(x + 24)/4

For another function of y

y = 3/4|x-6|-8

y= 3/4( x - 6) -8

y = 3(x - 6 - 32)/4

4y = 3(x - 38)

y = 3(x - 38)/4
