Question 13 (5 points)
m_1 = (4x + 9)º and m_2 = (x - 14)° in the given figure. Find x.

Answers

Answer:

x=19°

Step-by-step explanation:

Line n and l form a right angle. We know that because line m and l are parallel to each other and line n crosses through them as a vertical line.

Right angles always add up to 90°.

So, Angle 1 add Angle 2 equals 90°.

4x+9+x-14=90°

Collect the like terms:

Like terms are terms with the same variables and powers.

4x+x=5x

9-14= -5

Form an equation:

5x-5=90°

Do inverse operations to isolate x.

90+5=95°

95÷5=19° (We divide by 5 because, in algebra, when a number is next to a letter, it means times, so we have to do the opposite and divide).

So, x=19°

Evaluate (cot90)(cos45) + sec45 exactly. No decimals allowed, rationalize if necessary

Answers

Answer:  [tex]\sqrt{2}[/tex]

======================================================

Explanation:

Rewrite each trig function terms of sine and/or cosine. Then use the unit circle to find that,

[tex]\cot(90^{\circ})\cos(45^{\circ}) + \sec(45^{\circ})\\\\\frac{\cos(90^{\circ})}{\sin(90^{\circ})}\cos(45^{\circ}) + \frac{1}{\cos(45^{\circ})}\\\\\frac{0}{1}*\frac{\sqrt{2}}{2} + \frac{1}{(\sqrt{2})/2}\\\\\frac{2}{\sqrt{2}}\\\\[/tex]

Now rationalize the denominator

[tex]\frac{2}{\sqrt{2}}\\\\\frac{2\sqrt{2}}{\sqrt{2}*\sqrt{2}}\\\\\frac{2\sqrt{2}}{\sqrt{2*2}}\\\\\frac{2\sqrt{2}}{\sqrt{4}}\\\\\frac{2\sqrt{2}}{2}\\\\\sqrt{2}[/tex]

Which is the exact value of [tex]\sec(45^{\circ})[/tex]

The portion [tex]\cot(90^{\circ})*\cot(45^{\circ})[/tex] evaluates to 0 and goes away.

Answer:

y^3+9y^2+27y+27

Step-by-step explanation:

Step 1: Start by understanding FOIL. First. Outer. Inner. Last.

Step 2: In this case we have three sets of parenthesis not 2. So we have to do the same thing but multiply 2 (y+3) sets by y and 3 instead of only multiplying y and 3 by one set.

Step 3: So we get y^3+6y^2+9y+3y^2+18y+27.

This simplifies to y^3+9y^2+27y+27

Answers

Answer:

First of all take lcm u get

4 + 3 / 12k = 1

7 = 12k

k = 7/12

ques solved

Answer:

k = 7/12 or approximately 1.71

Step-by-step explanation:

We first need to convert both fractions denominators to their LCM (Lowest Common Multiple)

Multiples of 4: 4, 8, 12, 16

Multiples of 3: 3, 6, 9, 12

12 is the LCM

Then we convert both fractions to have a denominator of 12. Remember, whatever you do to the numerator must be done to the denominator.

1/3 x 4/4 = 4/12

1/4 x 3/3 = 3/12

The equation is now: 4/12k + 3/12k = 1

Add up both variables to get: 7/12k = 1

Divide both sides by 7/12: (12/7)7/12k = 1(12/7)

k = 12/7 or approximately 1.71

Which transformation can NOT be used to prove that ABC is congruent to
DEF?

O A. dilation
B. rotation
C. reflection
ОО
D. translation

Answers

Answer

A. dilation

Step-by-step explanation:

if we dilate the diagram it will be enlargedd so cannot be proved as congruent

The transformation that can not be used to prove that ABC is congruent will be dilation. The correct option is A.

What is transformation?

Transformation a process by which one figure, expression, or function is converted into another one of similar value. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

When the triangle is rotated its original shape and size will not change it only changes its position then the triangle will remain congruent.

When the triangle is reflected it means that its mirror image is formed then the size and shape will again remain unchanged the triangle will be congruent.

When the triangle is translated then also its size will not change only it changes its position. The triangle will be congruent.

When the triangle is dilated it means that the shape of the triangle is increased or decreased then the triangle will not be congruent when it is dilated.

Answers

Part A: 23

Part B: 13

Part C: Median for the males

Mean for the females

Part D: The day the movie premiered

Process to arrive at the above answers

The likely missing part of the question; The Box Plots are to compare The Number of Males and The Number of Females attending the latest superhero movie every day in a given month

The known parameters

The 5 number summary in a are;

[tex]\begin{array}{lcc}\mathbf{Summary}&\mathbf{Males}&\mathbf{Females}\\\\Minimum &0&0\\First \ Quartile, \ Q_1&2&5\\Second \ Quartile, \ median, Q_2&20&7\\Third \ Quartile, Q_3&25&10\\Maximum &50&18\\Outlier&&46\end{array}[/tex]

Part A: The Inter Quartile Range, IQR = Q₃ - Q₁

For the males, we have, IQR = 25 - 2 = 23

Part B: The difference between the median values for the males and females is given as follows;

Difference between median = Q₂ Males - Q₂ Females

Difference between median = 20 - 7 = 13

The difference between the median values for the males and females = 13

Part C:

The distribution of the data for the males is skewed left, with almost all the data in the first half

The better measure of center for the skewed data is the median, given

that three quarter of the data have values that are less than half of the

range of values in the data set, and that the median is close to the third

quartile, the mean will be located further towards the minimum value of

the data than the median

The distribution of the data for the females consists of the interquartile

range located approximately in the middle between the max and the min

values with the median being close to the first quartile, therefore, the

mean will be a better measure of center as it will be located further from

the first quartile and closer midway in the IQR

Part D;

The possible reason for the outlier in the data set may be due to the first day the latest super hero movie is premiered

a1=10 and an-1+3 for n is greater than and equal to 2

Answers

Answer:  10, 13, 16, 19

Explanation:

The notation [tex]a_1 = 10[/tex] says that the first term is 10.

The notation [tex]a_n = a_{n-1}+3[/tex] is the recursive rule that says "to find the nth term, we add 3 to the previous term". So we add 3 to each term to get the next one.

first = 10second = first+3 = 10+3 = 13third = second+3 = 13+3 = 16fourth = third + 3 = 16+3 = 19

Directions: Read the following selection, and answer the question that follows.Blue-Screen TechnologyThe camera rolls as an actor stands in front of a blue screen. The actor stands alone, saying his lines. However, when you see the actual movie, he is talking to a formidable seven-foot-tall monster in a creepy dark forest. A process called blue-screen technology is used to insert images into a background. Today, moviemakers use this process to combine digitally created, or computer-generated, characters with real people on the screen. Here's how it works:The scene calls for a real character to interact with a seven-foot-tall digitally created monster. First, the real character's part must be filmed. He may rehearse with another actor who plays the part of the monster. During the rehearsal, the "monster" might wear a tall hat to represent the stature of the monster. The real actor practices looking at the top of the hat during the scene so that it seems that he is looking up at a very tall creature. The actor gets used to where the monster stands and moves. The monster's movements are marked on the floor so that the actor doesn't walk on top of the monster during the scene. Then it is time for the scene to be shot. The actor stands alone in front of a blue screen and delivers his lines as if the monster were there. Eventually, the blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.Which of the following is a reasonable conclusion to draw from the reading?a.Scenes with seven-foot-tall monsters are easy to add with blue-screen technology.b.Movies are more fun to watch because of blue-screen technology.c.Adding special effects to movies using blue-screen technology isn't worth the effort.d.As a result of blue-screen technology, adding special effects to movies is easier and faster. 5-5 TIME TO REACH A FINANCIAL GOAL You have $33,556.25 in a brokerage account, and youplan to deposit an additional $5,000 at the end of every future year until your account totals$220,000.
