Answer:
x = 6
Step-by-step explanation:
In triangle ABC, BD is the bisector of angle ABD.
Therefore by angle bisector property:
[tex] \frac{x}{8} = \frac{3}{4} \\ x = \frac{8 \times 3}{4} \\ x = 2 \times 3 \\ \huge \red{ \boxed{ x = 6}}[/tex]
A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.
Explain how to find the arc length exactly, and then approximate it to one decimal place.
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
What is the second step in sketching the graph of a rational function?
A. Sketching the function's graph and plotting additional points as guides when needed
B. Using test numbers to find where the function is positive and where it is negative
C. Choosing test numbers to the left and right of each of the function's zeros and finding the value of the function at each test number
D. Finding the function's zeros and vertical asymptotes and plotting them on a number line
Answer:
C. Choosing test numbers to the left and right of each of the function's zeros and finding the value of the function at each test number
Step-by-step explanation:
Rational function: In mathematics, the term "rational function" is determined as any specific function that can be described through any "rational fraction", in other words, an algebraic fraction, involving both the denominator and the numerator are considered as polynomials. Therefore, the coefficients of specific polynomials are ought not to be in rational numbers and can be considered in the K field.
In the question above, the given statement represents option C is correct.
Final answer:
The second step in sketching the graph of a rational function involves identifying and plotting the function's zeros and vertical asymptotes on a number line.
Explanation:
The second step in sketching the graph of a rational function is (D) Finding the function's zeros and vertical asymptotes and plotting them on a number line. This step is crucial before sketching the graph because it gives an initial outline of where the function will not be defined (vertical asymptotes) and where it crosses the x-axis (zeros of the function). After identifying these critical points, one can choose appropriate test numbers around each zero and asymptote to determine the behavior of the function in those regions, which can later aid in sketching the graph with more accuracy.

Find an equation equivalent to r = 10 sin theta rectangular coordinates.
We have been an equation in polar coordinates [tex]r=10\text{sin}(\theta)[/tex]. We are asked to write our equation in rectangular coordinates.
We know that the equation [tex]r=2b\text{sin}(\theta)[/tex] is equation of a circle with a radius [tex]|b|[/tex] and center at [tex](0,b)[/tex].
Let us find the value of b.
[tex]2b\text{sin}(\theta)=10\text{sin}(\theta)[/tex]
[tex]\frac{2b\text{sin}(\theta)}{2\text{sin}(\theta)}=\frac{10\text{sin}(\theta)}{2\text{sin}(\theta)}[/tex]
[tex]b=5[/tex]
We know that equation of a circle in rectangular coordinates is [tex](x-h)^2+(y-k)^2=r^2[/tex]
Since [tex]b=5[/tex], so radius is 5 and center is at point (0,5).
[tex](x-0)^2+(y-5)^2=5^2[/tex]
[tex]x^2+(y-5)^2=25[/tex]
Therefore, our required equation would be [tex]x^2+(y-5)^2=25[/tex].

What are the Tree Numbers
Answer:
679.
Step-by-step explanation:
There is either a 1, 4 or 7 in the number.
From the second guess, 189, 1 cannot be in the number , either 8 or 9 are in right place. Also 4 or 7 are in the number.
9 6 4: 9 may be in the number, also 4 or 6.
No 2,3 or 5.
2 8 6 this tells us there is no 8 , and 9 is the last digit.
As there is no 2 there must be a 6 in the number
So the number contains a 9 and a 6.
The third number is either a 4 or a 7, but from the 964 result it cannot be a 4 because 6 is included.
So it either 679 or 769.
But 964 had 6 in the wrong place so the number is 679.
I think the answer is 679 because you every numbers make sense except for 679.

Write an equation of the line that passes through (0,3) and (4,2).
Answer:
y= [tex]\frac{-1}{4}[/tex]x+3
Step-by-step explanation:
To write an equation for a line, we will first need to find the slope of the graph. This can be done by using the slope formula:
m= [tex]\frac{y_{2-y_{1}} }{x_{2}-x_{1}}[/tex]
Now, we can plug these points in this equation.
m= [tex]\frac{2-3}{4-0}[/tex] --> m= [tex]\frac{-1}{4}[/tex] .
Since we have derived the slope, we can simply use one of the points listed to solve for our other values by plugging them into the line formula:
y= mx+b
------------
2= [tex]\frac{-1}{4}[/tex](4)+b
2=-1+b
3= b
Therefore, the equation we get is:
y= -[tex]\frac{-1}{4}[/tex]x+3

What is the answer? To this question
Answer:
D.
Step-by-step explanation:
Firstly, we must look at the absolute value symbol. This means that if d is positive, it must be a number greater than 3. If d is negative, the number must be less than -3 (for the absolute value to be greater than 3.)
This results in A and D being possible solutions. HOWEVER, we must look at the ">" symbol.
Notice how the symbol solely represents "Greater than", and not "Greater than OR equal to".
This means that the number line must have OPEN circles at -3 and 3. This will give you solution D.

What is the absolute deviation of Victoria’s quiz score from the mean?
A. 0 points
B. 2 points
C. −1 point
D. 1 point
Please give the right answer
Answer:
B. 2 points(Approximately)
Step-by-step explanation:
The mean absolute deviation (MAD) is defined as
[tex]MAD=\frac{\Sigma |x_{i}-\mu| }{N}[/tex]
Where [tex]\mu[/tex] is the means and [tex]N[/tex] is the total number of elements.
First, we need to find the mean:
[tex]\mu = \frac{\Sigma x_{i} }{N} =\frac{18+12+15+10+13+20+16+12+18+6}{10}= \frac{140}{10}\\ \mu=14[/tex]
Then, we calculate the difference between each value and the mean, from that difference, we are gonna use the absolute value.
18 - 14 = |4|
12 - 14 = |-2|
15 - 14 = |-1|
10 - 14 = |-4|
13 - 14 = |-1|
20 - 14 = |6|
16 - 14 = |2|
12 - 14 = |-2|
18 - 14 = |4|
6 - 14 = |-8|
Now, we sum all terms and divide them by the total number of elements, which are 14.
[tex]MAD=\frac{4+2+1+4+1+6+2+2+4+8}{14}= \frac{34}{14}\\ MAD \approx 2.4[/tex]
Therefore, the absolute deviation is about 2 points. The right answer is B.

You and some friends buy tickets to a raffle at your school. You can each buy one ticket. In total 150 tickets were sold. The probability that on of your friends win the raffle is 1/30. How many friends of yours bought tickets
Answer:5
Step-by-step explanation:
Given
There are total of 150 ticket
If the probability to win a raffle is [tex]\frac{1}{30}[/tex]
[tex]Probability =\frac{\text{Favorable outvome }}{\text{Total outcome}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{\text{Total no of tickets}}[/tex]
[tex]\frac{1}{30}=\frac{\text{no of tickets bought}}{150}[/tex]
no of tickets bought[tex]=\frac{150}{30}=5[/tex]
and no of tickets bought=No of friends
Therefore there 5 persons who bought tickets

PLEASE HELP!! S is the center of the circle. Suppose that JK=12, LK=12, NS=8, and PS= 2x - 6. Fine the following
Answer:
x = 7
LP = 6
Step-by-step explanation:
JK = 12
LK = 12
NS = 8
PS = 2x - 6
radius bisects the chords JK and LK because it is perpendicular to them.
JK = JN + NK = 6 + 6 = 12
LK = LP + PK = 6 + 6 = 12
LP = 6
radius= root(6^2 + 8^2) = 10 then PS = 8 = 2x -6,
8 = 2x - 6
14 = 2x
x = 7
