Ursula could have drawn a pentagon because all angles of a pentagon are obtuse angles.

An angle greater than 90° is called an obtuse angle.

Trapezoid: A quadrilateral with at least one pair of parallel sides is called

a trapezoid.

In a trapezoid, all the angles are not greater than 90° i.e. all the angles are not obtuse angles.

Similarly, In triangles and parallelograms, all the angles are not obtuse angles.

Pentagon: In a pentagon, all angles are greater than 90° i.e. obtuse angles.

Final answer:

The square root of -9 is not -3 but 3i, indicating the need for complex numbers to describe the square root of negative numbers, with 'i' denoting the imaginary unit.

Explanation:

The value of the square root of -9 is not -3 because the square root operation defined for real numbers does not apply to negative numbers in the same way. Instead, when dealing with the square root of a negative number, we enter the realm of complex numbers.

A complex number is a combination of a real part and an imaginary part. The square root of -1 is defined as i, the imaginary unit. Therefore, the square root of -9 is correctly expressed as 3i, not -3. This is a critical distinction because the result provides a basis for complex arithmetic, expanding the scope of mathematical operations into the complex plane.

Complex numbers and imaginary numbers are fundamental in various fields of science and engineering, particularly in situations involving quadratic equations with no real roots or in the analysis of electrical circuits. Recognizing the utility of the imaginary unit, i, allows for solving equations that otherwise would not have solutions within the set of real numbers.

Answer: Rational numbers are any numbers that can be expressed by a fraction with integers in both the numerator and the denominator. The amount of time and paper it takes to put them into an increasing line depends on how many numbers there are and how big of a range they have.

1.Rewrite improper fractions

An improper fraction is a fraction with a bigger numerator than denominator. These numbers can be difficult to compare. For example, numbers such as 26/7, 31/9, 12/5, 8/3 and 22/13 do not have an obvious highest or lowest term. Rewrite improper fractions as mixed numbers or as numbers with decimals. To turn an improper fraction into a decimal, divide the numerator by the denominator. If the denominator is large or a prime number greater than five, use a calculator. For example, divide the numbers 26/7, 31/9, 12/5, 8/3 and 22/13 to create 3.71, 3.44, 2.4, 2.67 and 1.69.

2.Find the highest and lowest terms

Figure out where your number line starts and ends. Put the lowest term on the far left and the highest term on the far right. Remember, negative numbers are lower than positive numbers, and the greater a negative number's distance from zero, the lower it is.

3.Mark benchmark terms

Draw a line extending through your lowest and highest points. Figure out some major points between these values and mark them on your line. For example, if your lowest number is negative 25 and your highest number is 50, find where zero and 25 would be. Mark these as benchmarks or guides.

4.Fill in the remaining numbers

Using your guides, fill in the rest of the numbers. Start with the lowest values on the left and work your way up.  

Rational and irrational numbers can be ordered from least to greatest by converting them into decimal forms. Once in decimal form, they can be compared and ordered just like regular real numbers.

To order rational and irrational numbers from least to greatest, first you need to understand what these numbers are. Rational numbers are numbers that can be expressed as a ratio of two integers, while irrational numbers cannot be expressed as such ratio and their decimal expansions are non-repeating and non-terminating.

If you are given both rational and irrational numbers, you can start by converting all of the numbers to decimal form if they are not already. Then, you can simply order them from least to greatest, just like how you order regular real numbers.

For example, if you are given the numbers 3/2, √2, and 1. You would convert 3/2 to 1.5 and approximate √2 as 1.414. Then you would order them as 1 (1.0), √2 (1.414), and 3/2 (1.5).

Answer:

12.25 or 49/4

Step-by-step explanation:

12.25 is the decimal version because 1/4 is equal to 0.25 as a decimal and then add the 12 on.

13/4 is the improper fraction. To get an improper fraction, you multiply the main number (12) by the denominator (4) this gives you 48. Then, you have to add your numerator (1), leaving you with 49 over 4.

The value of the mixed fraction number 12 ¹/₄ will be 12.25.

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The mixed fraction number is given below.

⇒ 12 ¹/₄

Convert the mixed fraction number into a decimal number. Then we have

⇒ 12 ¹/₄

⇒ 12 + ¹/₄

⇒ 12 + 0.25

⇒ 12.25

The value of the mixed fraction number 12 ¹/₄ will be 12.25.

Answer:

The correct option is D.

Step-by-step explanation:

It is given that

[tex]\sin \theta =\frac{-77}{85}[/tex]

[tex]\cos \theta =\frac{36}{85}[/tex]

The angle of terminal ray is θ, it means the angle between x-axis and terminal ray is θ.

[tex]\sin \theta =\frac{perpendicular}{hypotenuse}[/tex]

[tex]\cos \theta =\frac{base}{hypotenuse}[/tex]

Therefore the length of perpendicular is 77 and the base of the triangle is 36.

Since sinθ is negative and cosθ is positive, it means point must be lies on fourth quadrant because in fourth quadrant cosine in positive but sine is negative.

The point of terminal ray is (base, perpendicular) and the sign are used according to the quadrant.

Therefore the point of terminal ray is (36,-77) because in fourth quadrant x is positive but y is negative. Option D is correct.

The coordinates of the point (x, y) on the terminal ray of angle theta are (36, -77).

Given

Three trigonometric functions for a given angle are shown below.

sin theta = -77/85, cos theta=36/85, tan theta=77/36.

A ray is defined as the initial side of the angle.

The second ray which  is called the terminal side of the angle.

The value of the sin and cos theta then, the co-ordinate lies in the fourth quadrant.

Therefore, the coordinates of the point (x, y) on the terminal ray of angle theta are (36, -77).

Mean of resulting data = 7 times mean of original data=7a

Step-by-step explanation:

Given that all values in a data set are multiplied by 7. to find the mean of the new set.

Let {x1,x2....xn} be the original data set.

The mean of this data set a= [tex]\frac{x1+x2+...+xn}{n}[/tex]

Now multiply all values by 7

New data set

= {7x1, 7x2...7xn}

Sum of these = 7(x1+x2+..+xn) = 7 times sum of original data set

No of element = n for both the sets

Hence new mean = 7 * mean of original set.=7a

in other words, if the mean of the values in a data set is a. If each of the values in the data set were multiplied by 7, new mean would be 7a.

Final answer:

The weekly take-home pay from a $45,000 annual salary with a 22% total tax burden is approximately $675.00 after taxes.

Explanation:

To calculate the take-home pay from a paycheck when you know the annual salary and the total tax rate, you must first determine the amount of money deducted for taxes and then subtract that from the gross (before-tax) pay. If a job pays $45,000 per year and the total tax burden is 22%, we can find the annual take-home salary and then divide by the number of pay periods per year to get the weekly take-home pay.

First, calculate the total annual taxes: $45,000 * 0.22 = $9,900.

Next, subtract the annual taxes from the annual salary to get the annual take-home salary: $45,000 - $9,900 = $35,100.

Since there are 52 weeks in a year, divide the annual take-home salary by 52 to find the weekly take-home pay: $35,100 / 52 \\approx $675.00.

Therefore, the weekly take-home pay would be approximately $675.00.

Step-by-step explanation:

We are shifting the absolute value function

f(x) = |x| to

g(x) =  | x +h| + k

where  h is a shift left if h >  0

                               right if h < 0

 and  k is a shift up if k> 0

                           down if k< 0

Since the graph is shifted down and to the right

k is <0 and h < 0

where k = -4 and h=-5
