Just copy the image down onto your paper

According to the given image, the given function is increasing at (C) x > 2.

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.

The sets X and Y are collectively referred to as the function's domain and codomain, respectively.

The relationship between the input or domain and the output or range is known as the function rule.

If and only if there is a single value in the range for each domain value, a relation is a function.

A function is denoted by the notation f x, where x is the input value.

A function has the general form y = f x.

So, let's consider the given image:

The function is increased from the point +2 on the x-axis.

Which can be the point x > 2.

Therefore, according to the given image, the given function is increasing at (C) x > 2.

What are similar triangles?

If two triangles' corresponding angles and sides are identical and their corresponding sides are proportional, or if the ratios between the lengths of the corresponding sides are comparable, then two triangles are said to be similar.

From the figure,

AB= 21.15 meters

AE = AB - BE = 21.15 - 16.8 = 4.35 meters

BC= height, h

The triangles ABC and ADE are similar triangles

So,

AE/DE  = AB/BC

4.35 / 1.55 = 21.15/  h

h = ( 21.15 * 1.55 ) / 4.35

  = 32.78/4.35 = 7.54 m

So, the height of the tree to the nearest hundredth of a meter = 7.54 m

Micah increased his practice time by 80%.

What is percent?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

Given:

Micah is preparing for a piano recital .

He practices for 50 minutes on Monday and 90 minutes on Wednesday.

Micah increased his practice time by 40%.

%increase = (Final value - starting value) / |starting value| x 100

                 = (90 - 50) / |50| x 100

                  = 40/50 x 100

%increase = 80%

Melinda will have painted 56 percentage of a wall for the time taken by Desiree, when she has finished painting 1 wall.

The computation of the difference between the time taken by Desiree and Melinda to paint walls at their respective speeds can be shown using the generalized calculations, as expressed hereunder,

Desiree will take 4x the time for painting 1 wall completely (25x4=100%). Thus, the amount of time taken by Melinda will also be 4x of her actual time, as below,

14×4= 56%

There are 365 more general parking spots than accessible parking spots.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, the ratio of accessible parking spots to general parking spots is 2:75.

A parking lot is designed to hold 385 parking spots.

So, 2+75=77

Number of general parking spots

= 75/77 ×385

= 75×5

= 375

Number of accessible parking spots

The vertical distance of the balloon from the ground will be 960.50 feet.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

From a sight-seeing balloon, Justin estimates a 34° point of sadness to a milestone that is 1424 feet away, estimating on a level plane.

The vertical distance of the balloon from the ground will be given as,

tan 34° = h / 1424

Simplify the equation, then we have

h = 1424 tan 34°

h = 960.50 feet

The value of test statistic for test of independence is 62.5

The Chi-square test of independence checks that two variables are related or not. We have to count for two nominal variables. We also believe that the two variables are unrelated. The test allows us to determine whether or not our idea is plausible.

The sections that follow go over what we need for the test, how to perform it, understanding the results, statistical details, and p-values.

Given,

the table shows the beverage preferences for random samples of teens and adults.

For calculating the test statistics,

First wee need to calculate the expected values of every observed values.

Expected values for teens,

[tex]E(50)=\frac{250*400}{1000}=100\\\\E(100=)\frac{250*400}{1000}=100\\\\E(200)=\frac{400*400}{1000}=160\\\\E(50)=\frac{100*400}{1000}=40[/tex]

Expected values for adults,

[tex]E(200)=250-100=150\\\\E(150)=250-100=150\\\\E(200)=400-160=240\\\\E(50)=100-40=60[/tex]

Now, the test statistic is given by:

[tex]X^2=\frac{\sum\limits^n_{i=1}(O_i-E_i)^2}{E_i}[/tex]

Where, Ei=expected value and Oi = observed value

[tex]X^2=\frac{(50-100)^2}{100}+\frac{(100-100)^2}{100}+...\frac{(200-240)^2}{240}+\frac{(50-60)^2}{60}=62.5[/tex]

Step-by-step explanation:

Let's start with what we know:

6 red

10 purple

5 green

So, we have 25 total and 5 green. But we are trying to find the probability it won't be green, in which we have 20 marbles. So the probability it won't be green is 20/25 = 4/5.

The equation is 128 + 2x = 180.

The angles that are in the same position on two parallel lines intersected by a transversal line on the parallel lines.

Corresponding angles are equal.

We have,

The sum of the same-side interior angles between two parallel lines is supplementary

This means,

128 + 2x = 180

2x = 180 - 128

2x = 52

x = 26

The value of x is 26.

The solutions to the inequalities are x ≤ -5, x ≥ 1 and x > 1

From the question, we have the following parameters that can be used in our computation:

-4x ≥ 20

8 ≤ -4(x - 1)

3x - 2 > 4 - 3x

Next, we solve the inequalities

Inequality 1

-4x ≥ 20

Divide both sides of the inequality by -4

So, we have the following representation

x ≤ -5

Inequality 2

8 ≤ -4(x - 1)

Divide both sides of the inequality by -4

So, we have the following representation

-2 ≥ -x - 1

Rewrite as

x + 1 ≥ 2

Evaluate the like terms

x ≥ 1

Inequality 3

3x - 2 > 4 - 3x

Add to both sides of the inequality 3x

So, we have the following representation

6x - 2 > 4

Add to both sides of the inequality 2

So, we have the following representation

6x  > 6

The set of input values (x) for which a function generates an output value is known as the domain of the function (y).

we can write [tex]y = f(x).[/tex]

domain is the full set of x-values that can be plugged into a function to produce a y-value.

The most effective approach to finding a domain will depend on the type of function.

The domain is expressed using an open bracket or parenthesis, the domain's two endpoints separated by a comma, and then a closed bracket or parenthesis.

To find domain of function we should know the property of that function like what the function can take inside it.

The basic difference between the addition and subtraction of polynomials has been explained below.

A polynomial is a mathematical expression containing two or more algebraic terms containing variables and their coefficients that involve operations such as addition, subtraction, and multiplication.

The basic difference between the addition and subtraction of polynomials is that since subtraction is the inverse of addition, all terms get the opposite sign upon subtraction. For example -

In addition - 2x²+3x+4 and 3x²+7x+9 are added and we get = 6x²+10x+13

In subtraction - The same polynomials are subtracted = -x²-7x-5

Henceforth, we see that the signs have changed to the opposite.
