Answer:

16. Angle C is approximately 13.0 degrees.

17. The length of segment BC is approximately 45.0.

18. Angle B is approximately 26.0 degrees.

15. The length of segment DF "e" is approximately 12.9.

Step-by-step explanation:

By the law of sine, the sine of interior angles of a triangle are proportional to the length of the side opposite to that angle.

For triangle ABC:

[tex]\displaystyle \frac{\sin{C}}{\sin{A}} = \frac{c}{a}[/tex].

[tex]\displaystyle \sin{C} = \frac{c}{a}\cdot \sin{A} = \frac{6}{26}\times \sin{103\textdegree}[/tex].

[tex]\displaystyle C = \sin^{-1}{(\sin{C}}) = \sin^{-1}{\left(\frac{c}{a}\cdot \sin{A}\right)} = \sin^{-1}{\left(\frac{6}{26}\times \sin{103\textdegree}}\right)} = 13.0\textdegree{}[/tex].

Note that the inverse sine function here [tex]\sin^{-1}()[/tex] is also known as arcsin.

By the law of cosine,

[tex]c^{2} = a^{2} + b^{2} - 2\;a\cdot b\cdot \cos{C}[/tex],

where

For triangle ABC:

Therefore, replace C in the equation with A, and the law of cosine will become:

[tex]a^{2} = b^{2} + c^{2} - 2\;b\cdot c\cdot \cos{A}[/tex].

[tex]\displaystyle \begin{aligned}a &= \sqrt{b^{2} + c^{2} - 2\;b\cdot c\cdot \cos{A}}\\&=\sqrt{21^{2} + 30^{2} - 2\times 21\times 30 \times \cos{123\textdegree}}\\&=45.0 \end{aligned}[/tex].

For triangle ABC:

Start by finding the cosine of angle B. Apply the law of cosine.

[tex]b^{2} = a^{2} + c^{2} - 2\;a\cdot c\cdot \cos{B}[/tex].

[tex]\displaystyle \cos{B} = \frac{a^{2} + c^{2} - b^{2}}{2\;a\cdot c}[/tex].

[tex]\displaystyle B = \cos^{-1}{\left(\frac{a^{2} + c^{2} - b^{2}}{2\;a\cdot c}\right)} = \cos^{-1}{\left(\frac{14^{2} + 6^{2} - 9^{2}}{2\times 14\times 6}\right)} = 26.0\textdegree[/tex].

For triangle DEF:

Apply the law of sine:

[tex]\displaystyle \frac{DF}{EF} = \frac{\sin{E}}{\sin{D}}[/tex]

[tex]\displaystyle DF = \frac{\sin{E}}{\sin{D}}\cdot EF = \frac{\sin{64\textdegree}}{39\textdegree} \times 9 = 12.9[/tex].

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We have the following line:

[tex]2x-3y = 12\\2x-12 = 3y\\y = \frac {2} {3} x-4[/tex]

If the line we wish to find is perpendicular to the one given, then its slope is given by:

[tex]m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {\frac {2} {3}}\\m_ {2} = - \frac {3} {2}[/tex]

Then the line is:

[tex]y = - \frac {3} {2} x + b[/tex]

We substitute the point:

[tex]6 = - \frac {3} {2} (2) + b\\6 = -3 + b\\b = 6 + 3\\b = 9[/tex]

Finally, the equation is:

[tex]y = - \frac {3} {2} x + 9[/tex]

Answer:

[tex]y = - \frac {3} {2} x + 9[/tex]

Answer:

(x − 4)2 + ( y + 6)2 = 49

Step-by-step explanation:

The equation of a circle with center (h, k) and radius r is                                (x − h)2 + (y − k)2 = r2.

Define h, k and r using the given values. So, h = 4, k = −6 and r = 7.

Substitute the values into the equation of a circle:

(x − 4)2 + (y − (−6))2 =72

Simplify.

(x − 4)2 + (y + 6)2 = 49

Therefore, the equation of the circle B with center B(4, -6) and radius 7 is   (x − 4)2 + (y + 6)2 = 49.

The equation of the circle B with center B(4,−6) and radius 7 is[tex]\rm (x-4)^2+(y+6)^2=49[/tex], the corrcet option is B.

A circle can be represented as;

[tex]\rm (x-h)^2+(y-k)^2=r^2[/tex]

Where h and k are the centers of the circle and r is the radius of the circle.

The equation of circle B with center B(4,−6) and radius 7.

Substitute all the values in the equation

[tex]\rm (x-h)^2+(y-k)^2=r^2\\\\\rm (x-4)^2+(y-(-6))^2=7^2\\\\\rm (x-4)^2+(y+6)^2=49[/tex]

Hence the equation of circle B with center B(4,−6) and radius 7 is[tex]\rm (x-4)^2+(y+6)^2=49[/tex], the correct option is B.

ANSWER

[tex]y = \frac{1}{3} \cos(x) - 2[/tex]

EXPLANATION

If the graph of y=cos⁡x is transformed to y=a cos ⁡(x−c)+d by a vertical compression by a factor of 1/3 and a translation 2 units down,

then

a=1/3

and d=-2.

The 'c' is a phase shift since it is not given, it means it is zero.

Therefore the new equation is:

y=1/3cos⁡(x-0)−2

This simplifies to:

y=1/3cos⁡x−2

The correct option is C.

Answer:

The new equation is y = 1/3 cos(x) - 2 ⇒ 3rd answer

Step-by-step explanation:

* Lets revise the trigonometry transformation

- If the equation is y = a cos(x - c) + d

# a is the scale factor of a vertical stretch or compression  

# c is the phase shift  (negative is to the right, positive is to the left)

# d is the vertical shift

- If y = cos(x)

∴ a = 1 , c = 0 , d = 0

* Now lets solve the problem

∵ There is a vertical compression by a factor of 1/3

∴ a = 1/3

∵ There is a translation 2 units down (vertical translation)

∴ d = -2

∵ There is now phase shift (horizontal translation)

∴ c = 0

* Now lets write the new equation

∴ y = 1/3 cos(x) - 2

* For more understand look to the attached color graph

Answer:

I need to know the data to answer the question

Step-by-step explanation:

Adding a score of 0 to your data will lower both the mean and median, and could potentially increase the standard deviation and affect the percentile rankings.

Adding a score of 0 to your data set will affect both the mean (average) and the median (middle value) of the scores.  Thus, adding a zero will decrease the mean. The median is the middle score when all the scores are arranged in order. If you add a score that is lower than the current median score, the median will either stay the same or decrease, depending on the number of scores. If the number of scores is odd, the median will remain the same, if the number is even, the median will decrease.

The standard deviation is a measure of the variability or dispersion of a set of scores. If all values are the same, the standard deviation is zero. The standard deviation is small when the scores are close to the mean and larger when the scores vary more from the mean. Adding a score of zero could increase the standard deviation, depending on the other scores.

The percentiles in your data represent the value below which a given percent of data falls. Adding a score of 0 could potentially affect the percentile rankings of the other scores.

Answer:

999

Step-by-step explanation:

Regrouping used to be called borrowing. Since no single column can have a digit larger than 9, then you would have the number 999 where you would never have to "borrow", or "regroup

Final answer:

A three-digit number that requires no ungrouping for subtraction should have each digit greater than the corresponding digit in the number being subtracted. For example, subtracting 234 from 453 requires no ungrouping because each digit in 453 is greater than the corresponding digit in 234.

Explanation:

The student's question pertains to the process of subtraction without requiring ungrouping, also known as regrouping or borrowing, when subtracting from a three-digit number. To avoid ungrouping, the number we subtract from should have each digit larger than the corresponding digit of the number being subtracted. For simplicity, let's consider subtracting a three-digit number of the form XYZ, where X, Y, and Z are individual digits. To ensure there's no need for ungrouping, the number from which we are subtracting should have each place value (hundreds, tens, and ones) greater than or equal to those in XYZ.

For example, if we take the number 453 and subtract 234 from it, no ungrouping is needed because 4 is greater than 2, 5 is greater than 3, and 3 is greater than 4. Hence, any three-digit number with digits greater than those of the subtrahend in the corresponding place values would satisfy the condition of needing no ungrouping to subtract from. By following this rule, the process of subtraction becomes straightforward without the complication of borrowing across place values.

= 4x + 5

The algebraic expression that represents the total weight of all the suitcases (Anna's and Tamara's) is 6x + 5.

To find the total weight of all the suitcases, we need to add the weights of Anna's four suitcases and Tamara's four suitcases.

Anna's suitcases' weights: x + 4 and 4x - 5

Tamara's suitcases' weights: -3x + 2 and 2x + 4

The total weight can be represented by the algebraic expression:

Total weight = (x + 4) + (4x - 5) + (-3x + 2) + (2x + 4)

Now, let's simplify the expression:

Total weight = x + 4x - 3x + 2x + 4 - 5 + 2 + 4

Total weight = 6x + 5

After calculating the total involuntary deductions for FICA, Federal withholding, and State withholding, we subtract this total from the gross pay to determine the amount available for housing and fixed expenses, which is $2023.63.

To find out how much you are allowed for housing and fixed expenses, we first need to calculate the total involuntary deductions. This is done by applying the given percentages to the gross pay.

For the FICA it would be: $2759.00 * 7.65% = $211.16

Federal withholding would be: $2759.00 * 12% = $331.08

And for the State withholding: $2759.00 * 7% = $193.13

You'll then add all the deductions together: $211.16 + $331.08 + $193.13 = $735.37

The final step is to subtract the total deductions from the gross pay: $2759.00 - $735.37 = $2023.63

Hence, you are allowed $2023.63 for housing and fixed expenses.

To calculate the amount allowed for housing and fixed expenses, subtract the involuntary deductions from the gross pay which is $2,023.19

To calculate the amount allowed for housing and fixed expenses, we need to subtract the involuntary deductions from the gross pay. First, calculate the FICA deduction by multiplying the gross pay by 7.65% (0.0765). Next, calculate the federal withholding by multiplying the gross pay by 12% (0.12). Finally, calculate the state withholding by multiplying the gross pay by 7% (0.07). Subtract the sum of these deductions from the gross pay to find the amount allowed for housing and fixed expenses.

Gross pay: $2,759.00

FICA deduction: $2,759.00 x 0.0765 = $211.60

Federal withholding: $2,759.00 x 0.12 = $331.08

State withholding: $2,759.00 x 0.07 = $193.13

From any point (x, y) on the parabola the focus and directrix are equidistant.

Using the distance formula

[tex]\sqrt{(x-4)^2+(y-1)^2}[/tex] = | y - 5 |

Squaring both sides

(x - 4)² + (y - 1)² = (y - 5)² ← distribute the factors in y

(x - 4)² + y² - 2y + 1 = y² - 10y + 25 ( subtract y² - 10y + 25 from both sides )

(x - 4)² + 8y - 24 = 0  ( subtract (x - 4)² from both sides )

8y - 24 = - (x - 4)² ← add 24 to both sides )

8y = - (x - 4)² + 24 ( divide both sides by 8 )

y = - [tex]\frac{1}{8}[/tex] (x - 4)² + 3

Hence

f(x) = - [tex]\frac{1}{8}[/tex] (x - 4)² + 3 → C
