What is value of x?
Enter your answer in the box.
x=
Answers
Answer:
[tex]x=27[/tex]
Step-by-step explanation:
Notice that Angle A is being bisected.
Hence, we can use the Angle Bisector Theorem to write the following proportion:
[tex]\frac{x+8}{10}=\frac{2x-5}{14}[/tex]
Solve for x. Cross-multiply:
[tex]10(2x-5)=14(x+8)[/tex]
Distribute:
[tex]20x-50=14x+112[/tex]
Subtract 14x from both sides:
[tex]6x-50=112[/tex]
Add 50 to both sides:
[tex]6x=162[/tex]
Divide both sides by 6. Hence, the value of x is:
[tex]x=27[/tex]

Answer:
data points or values are nearer to the mean
Step-by-step explanation:
Given that mean absolute deviation tells you how to spread out or how clustered around the mean a set of data is.
Hence, in a comparison of sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean.
On the other hand, a lower mean absolute deviation indicates that the data points are nearer to the mean than a data set with a higher mean absolute deviation

In which situation below would you want to use the Explicit Formula instead of the Recursive Formula?
A. Find the 4th term when the first term is 7 and the common difference is -2.
B.Find the 7th term when the first term is -1 and the common difference is 10.
C.Find the 106th term when the first term is 2 and the common difference is 5.
D.Find the 11th term when the first term is -3 and the common difference is 4.
Answers

Answer:
all of them, possibly excepting the 4th term
Step-by-step explanation:
The recursive formula is good if you have terms near the one of interest. It might be used for the 4th term, but that would require that you compute the three previous terms:
7, 5, 3, 1 . . . . requires 3 subtractions
It can be about as easy to calculate ...
a4 = 7 -2(3) = 1 . . . . requires two* subtractions and a multiplication
__
However, for the 7th, 11th, and 106th terms, it is impractical to list all previous terms. The explicit formula is a better choice.
A. a4 = 7 -2(3) = 1
B. a7 = -1 +10(6) = 59
C. a106 = 2 +5(105) = 527
D. a11 = -3 +4(10) = 37
_____
* The explicit formula is ...
an = a1 +d(n -1)
The operations identified in this formula (in the order required by the Order of Operations) are subtraction, multiplication, and addition. For a negative common difference, that amounts to two subtractions and a multiplication.
For manual evaluation, the work involved in using the recursive or explicit formulas for the 4th term is about the same, if the arithmetic is easily done mentally (as here).

Find f^-1(x) (the inverse)
Answers
9514 1404 393
Answer:
does not exist
Step-by-step explanation:
The notation f^-1(x) usually refers to the inverse function. That is, if we have the functional relation
y = f(x)
Then the inverse function f^-1(x) will give you ...
x = f^-1(y)
__
In order for an inverse function to exist, the original function must pass the "horizontal line test." That is, any horizontal line can intersect the function's graph in, at most, one point.
Here, the function f(x) = 245 is a horizontal line, so the horizontal line test fails. The horizontal line at y=245 will intersect f(x) in an infinite number of points.
So, f(x) = 245 does not have an inverse function. f^-1(x) does not exist.
_____
Alternate interpretation of the question
Sometimes, an exponent is applied to a function name when the intended operation is application of the exponent to the function value. For example, you may see sin²(x) when the intended meaning is sin(x)². The application of an exponent to the function name could be confused with multiple applications of the function: sin²(x) = sin(sin(x)), as the notation is sometimes used for this purpose, too.
If what you intend by f^-1(x) is really f(x)^-1, then you can say ...
f(x)^-1 = 1/245

by 8:00 a.m., the snack bar had made $3,256 in sales. By noon, the snack bar's total sales were $8,821. On average how much money did the snack bar take in each hour between 8:00 a.m. and noon?
Answers
Answer:
$1,391.25
Step-by-step explanation:
Noon would be 12:00 PM which would be 4 hours ahead of 8:00 AM
We subtract $8,821 by $3,256 to get the amount earned between 8:00 AM and 12:00 PM
$8,821 - $3,256
= $5,565
The find the average taken in within those 4 hours we will have to divide the money earned by the hours
$5,565/4
= $1,391.25

In the diagram below, what is the equation that represents the relationship between the number of triangles and the perimeter of the figure they form? Use this table to help you create an equation.
Answers
Answer:
The perimeter of the figure as a function of the number of triangles is [tex]y = 6 + 4\cdot x[/tex].
Step-by-step explanation:
According to the diagram, we get the following facts:
i) For one triangle ([tex]x=1[/tex]), the total perimeter is ([tex]y=2\cdot 3 + 1\cdot 4 = 10[/tex]).
ii) For two triangles ([tex]x = 2[/tex]), the total perimeter is ([tex]y = 2\cdot 3 +2\cdot 4 = 14[/tex])
iii) For three triangles ([tex]x = 3[/tex]), the total perimeter is ([tex]y = 2\cdot 3 +3\cdot 4 = 18[/tex])
iv) For four triangles ([tex]x = 4[/tex]), the total perimeter is ([tex]y = 2\cdot 3 +4\cdot 4 = 22[/tex])
From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is [tex]y = 6 + 4\cdot x[/tex].

Courtney is twice as old as Andre and three years older than Natalie. Courtney is half Shari's age. The difference between Shari's age and Natalie's age is the same as the sum of Courtney's age and Andre's age. The equation below represents their ages.
Answers
The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.
Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:
C = 2A
C = N + 3
C = S/2
S - N = C + A
S = 2C, N = C - 3 and A = C/2, therefore we have
2C - (C - 3) = C + C/2
C + 3 = C + C/2
C/2 = 3 and C = 6
A = C/2
A= 6/2
A = 3
N = C - 3
N = 6 - 3
N = 3
S = 2C
S = 2 x 6
S = 12.
C = 6, A = 3, N = 3 and S = 12

Answers
Answer:
Check the explanation.
Step-by-step explanation:
The slope-intercept form of the equation is
[tex]y=mx + b[/tex]
where m is the slopeb is the y-interceptLine A:
[tex]y = 1 2 x + 2[/tex]
The slope of line A:
[tex]m_A=12[/tex] ∵ comparing with [tex]y=mx + b[/tex]
Line B:
[tex]y = -1 2 x + 7[/tex]
[tex]m_B=-12[/tex] ∵ comparing with [tex]y=mx + b[/tex]
Line C:
[tex]y = -2x + 4[/tex]
[tex]m_C=-2[/tex] ∵ comparing with [tex]y=mx + b[/tex]
Line D:
[tex]y = 12x + 5 4[/tex]
[tex]m_D=12[/tex] ∵ comparing with [tex]y=mx + b[/tex]
As we know that the product of the slopes of perpendicular lines is -1.
i.e. their slopes are opposite of the reciprocal of each other.
Now, let us check the OPTIONS:
Option A) A and B
Check:
[tex]m_A=12[/tex]
[tex]m_B=-12[/tex]
As the product of the slopes A and B is NOT -1, so the lines A and B are not perpendicular. Hence, option A is NOT true.
Option B) A and C
[tex]m_A=12[/tex]
[tex]m_C=-2[/tex]
As the product of the slopes A and C is NOT -1, so the lines A and C are not perpendicular. Hence, option B is NOT true.
Option C) B and C
[tex]m_B=-12[/tex]
[tex]m_C=-2[/tex]
As the product of the slopes B and C is NOT -1, so the lines B and C are not perpendicular. Hence, option C is NOT true.
Option D) A and D
[tex]m_A=12[/tex]
[tex]m_D=12[/tex]
As the product of the slopes A and D is NOT -1, so the lines A and D are not perpendicular. Hence, option D is NOT true.
Therefore, NO OPTION is correct.

Done
Hey
Answers
Answer:
D. Grant did not regroup the 4 tens when he subtracted 7.
Step-by-step explanation:
In the process of subtraction, regrouping is important so that each digit in the given numbers are placed appropriately before the required arithmetic operation is performed.
The correct step to Grant's solution are:
360 - 100 = 260
260 - 20 = 240
240 - 7 = 233
Grant's final answer ought to have been 233.
Going through his solution, he made a mistake while subtracting 7 from 240. He failed to regroup the 4 tens when he subtracted 7 from 240. Thus the essence of his wrong answer.
