Answer: Second option.
Step-by-step explanation:
Given the function f(x), which is:
[tex]f(x)=x[/tex]
And given the function g(x), which is:
[tex]g(x)=2[/tex]
You need to substiute the function [tex]g(x)=2[/tex] into the function [tex]f(x)=x[/tex] in order to find [tex](fog)(x)[/tex].
Therefore, through this procedure, you get this answer:
[tex](fog)(x)=(2)[/tex]
[tex](fog)(x)=2[/tex]
You can observe that this matches with the second option.
For this case we have the following functions:
[tex]f (x) = x\\g (x) = 2[/tex]
We must find [tex](f_ {0} g) (x).[/tex]
By definition of composite functions we have to:
[tex](f_ {0} g) (x) = f (g (x))[/tex]
We substitute g (x) into f (x), then we have:
[tex]f (g (x)) = 2[/tex]
Answer:
[tex]f (g (x)) = 2[/tex]

midpoint of the line segment (-1,5) (-8,-4)
Answer:
(- [tex]\frac{9}{2}[/tex], [tex]\frac{1}{2}[/tex] )
Step-by-step explanation:
Using the midpoint formula
Given 2 points (x₁, y₁ ) and (x₂, y₂ ), then midpoint is
([tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex])
with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (- 8, - 4), then midpoint
= ([tex]\frac{-1-8}{2}[/tex], [tex]\frac{5-4}{2}[/tex] )
= ( - [tex]\frac{9}{2}[/tex], [tex]\frac{1}{2}[/tex] )
Answer:-4.5,0.5
Step-by-step explanation:midpoint =x1+x2/2, y1+y2/2
-1+-8/2=x,-4+5/2=y
-9/2=x,1/2=y
-4.5=x, 0.5=y
What is the converse of the following true conditional? If the converse is true, rewrite the statements as a biconditional. If either is false, give a counterexample.
If two lines are parallel, they do not intersect.
Select one:
a. If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.
b. If two lines do not intersect, they are parallel. One statement is false. If two lines are parallel, they may intersect twice.
c. If two lines do not intersect, they are parallel. Both statements are true. Two lines are parallel if (and only if) they do not intersect.
d. If two lines do not intersect, they are not parallel. Both statements are true. Two lines are not parallel if (and only if) they do not intersect.
Answer: A
Step-by-step explanation: The converse of a conditional is when the two statements switch spots, for example:
Conditional: If someone like ice cream, they have brown hair
Converse: If someone has brown hair, they like ice cream
The converse of our given conditional would be:
If two lines do not intersect, they are parallel
This eliminates Option D
Next, the converse is false.
Skew lines (example attached) do not intersect and are also not parallel, meaning if two lines do not intersect, they could be either parallel or skew.
This eliminates Option C and B, leaving us with Option A
We want to find the converse statement to one given statement and see if it is true.
We will see that the correct option is a:
If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.
A general statement is written as:
If P then Q.
Where P and Q are two given propositions.
The converse statement to the above shown is:
If Q then P.
For this question, we have the statement:
If two line are parallel, they do not intersect.
Then we can write the converse statement as:
If two lines do not intersect, they are parallel.
Which is false, in 3-dimensions we can have two non-parallel lines that don't intersect each other (parallel lines must not intersect and also live on the same plane).
Then the correct option is the first one:
a: If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.

Find three consecutive numbers such that the sum of one-fourth the first and one-fifth the second is five less than one-seventh the third
Answer:
The numbers are -16,-15 and -14
Step-by-step explanation:
Let
x ----> the first number
x+1 ----> the second number
x+2 ---> the third number
we know that
(1/4)x+(1/5)(x+1)=(1/7)(x+2)-5
Multiply by (4*5*7) both sides
35x+28(x+1)=20(x+2)-140*5
35x+28x+28=20x+40-700
43x=-688
x=-16
so
x+1=16+1=-15
x+2=-16+2=-14
The numbers are -16,-15 and -14

Which angle of rotation is an angle of rotational symmetry for all figures?
Answer:
there isn't a direct answer for that because it depends on the shape.
but it has rotational symmetry if it can be rotated by an angle between 0° and 360°
The measure of A is 10° greater than the measure of B. The two angles are complementary. Find the measure of each angle.
The m A is ° and m B is °.
since its complementary, the sum if both angles equals 90 degrees.
you do x+x+10 so you combine like terms to get 2x+10=90
then you subtract 10 to get
2x=80
and divide by 2
x=40
angle a=50 degrees
angle b=40 degrees
Answer:
m < A = 50 degrees, m < B = 40 degrees.
Step-by-step explanation:
Complementary angles sum to 90 degrees, so:
A + B = 90
As A = B + 10:
B + 10 + B = 90
2B = 80
B = 40.
So A = 40 + 10 = 50.

Which of the following is NOT a possible value of the correlation coefficient?
A. negative 0.9
B. zero
C. positive 0.15
D. positive 1.5
E. negative .05
Answer:
positive 1.5
Step-by-step explanation:
by definition, the possible values for correlation coefficients are
-1 ≤ correlation coefficient ≤ 1
+1.5 lies outside this range and hence is not valid.
The correlation coefficient measures the strength and direction of a linear relationship between two variables, ranging from -1 to +1. Therefore, a value of positive 1.5, as listed in option D, is not a possible value for a correlation coefficient.
Explanation:In mathematics, particularly in statistics, a correlation coefficient is a measure of the strength and direction of the linear relationship between two variables on a scatterplot. The value of a correlation coefficient ranges from -1 to +1. A correlation coefficient of +1 indicates a perfect positive linear relationship, a correlation coefficient of -1 indicates a perfect negative linear relationship, and a correlation coefficient of 0 indicates no linear relationship.
Therefore, the answer to the question is: D. positive 1.5. This is not a possible value for a correlation coefficient because it lies outside the acceptable range of -1 to +1.

Answer:
The range for the equation is all real numbers.
Step-by-step explanation:
The range of an equation is the set of y-values that you can get by plugging in all possible x-values.
Another way to put it is, when you graph the equation, whatever y-values the line produces, is its range.
Graphing y=2x-3, you can see it is a graph with a positive slope that extends from negative infinity y-value to positive infinity x-value.

Kyra and her twin sister share shoes. In there closet they have four pairs of Sandals,five pairs of tennis shoes, and three pairs of boots. What is the probability that kyra selects a pair of sandals, put them on and then her sister selects a pair of tennis shoes?
Answer:
Step-by-step explanation:
The total number of shoes they share is
4 + 5 + 3 = 12
Kyra: 4/12 = 0.333333
Tennis Shoes: There are now 11 shoes. 5/11 = 0.46
The probability that Kyra selects a pair of sandals and her sister selects a pair of tennis shoes is 3/20.
Explanation:To find the probability that Kyra selects a pair of sandals and her sister selects a pair of tennis shoes, we need to determine the total number of possible outcomes and the number of favorable outcomes.
There are 4 pairs of sandals, 5 pairs of tennis shoes, and 3 pairs of boots in the closet. Assuming Kyra selects a pair of sandals first, she has 4 options. After Kyra selects the sandals, there will be 3 pairs of sandals left.
Since the sandals are chosen without replacement, her sister will have 5 options for the pair of tennis shoes. The total number of possible outcomes is the product of the options for each step: 4 * 5 = 20.
Therefore, the probability that Kyra selects a pair of sandals and her sister selects a pair of tennis shoes is 3/20.

Which graph represents the function p(x) = |x – 1|?
Answer:
The last one
Step-by-step explanation:
Your equation is p(x) = |x - 1|
The function equation can be represented by f(x) = a|x - h| + k
To find the vertex, you have to find (h,k)
In the equation p(x) = |x - 1|, 1 is h [since its (+h,k) not (-h,k)]
k is 0 since there is no +k after |x-1|.
So, your vertex will be at (1,0)
Thus, the answer is the last graph.
[I also graphed it on a graphing calculator so you can check. :) ]
The vertex will be at (1, 0).
Functions of graphs
The given equation is p(x) = |x - 1|
The function equation can be defined by f(x) = a|x - h| + k
To calculate the vertex, you have to identify (h, k)
In the given equation p(x) = |x - 1|, 1 exists h
[since its (+h, k) not (-h, k)]
k exists 0 since there does not exist +k after |x-1|.
So, the vertex will be at (1, 0).
Therefore, the graph represents the function p(x) = |x – 1| is option (d).

Answer:
89.95 + 4x =628.35
x = 134.60
Step-by-step explanation:
The trip to the dentist had a flat fee plus 4 cavities for a total cost of 628.35
fee + 4 * cost of cavity = 628.35
Let x = the cost of each cavity
89.95 + 4x =628.35
Subtract 89.95 from each side
89.95-89.95 + 4x =628.35-89.95
4x =538.40
Divide each side by 4
4x/4 =538.40/4
