Step-by-step explanation:
Segment AB falls on line 2x − 4y = 8. Segment CD falls on line 4x + 2y = 8. What is true about segments AB and CD?
They are perpendicular because they have the same slope of −2.
They are perpendicular because they have slopes that are opposite reciprocals of −2 and .
They are lines that lie exactly on top of one another because they have the same slope and the same y-intercept.
They are lines that lie exactly on top of one another because they have the same slope and a different y-intercept.
Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −2 and .Step-by-step explanation:
The given lines are
[tex]2x-4y=8[/tex]
[tex]4x+2y=8[/tex]
Let's rewrite each equation in the form [tex]y=mx+b[/tex]
[tex]2x-4y=8\\2x-8=+4y\\y=\frac{2x-8}{4} \\y=\frac{x}{2}-2[/tex]
[tex]4x+2y=8\\2y=8-4x\\y=\frac{8-4x}{2}\\ y=4-2x[/tex]
Now, let's use the perpendicular rule
[tex]m_{1} \times m_{2} =-1\\\frac{1}{2} \times (-2)=-1 \implies -1=-1[/tex]
As you can observe, the slopes satisfy the perpendicular rule, that means the lines are perpendicular.
Therefore, the right answer is the second choice because it states the rule of perpendicularity between the given lines.
Answer:
They are perpendicular because they have slopes that are opposite reciprocals of −2 and .

c) mean number of teachers in a car is 2.5
Step-by-step explanation:
modal number is 3 because that is the highest frequency of numbers of carsmedian number is 3 because it is the middle number when you expand the frequency table.mean number is 2.5 because that is the approximate average of all the numbers.Given: circle: k(O), m∠A = 101° m∠L = 79°, m LK = 122° Find: m AJ
Answer:
m arc AJ = 78°
Step-by-step explanation:
If angle A is 101° that means arc LKJ is 202° (the measure of an arc that an inscribed angle intercepts is twice the angle measure). If arc LKJ is 202° and arc LK is 122°, then arc KJ is 80° (m arc LK + m arc KJ = m arc LKJ).
If angle L is 79°, then the m arc AJK = 158° (the measure of an arc that an inscribed angle intercepts is twice the angle measure). If m arc AJK = 158° and m arc KJ is 80°, then the m arc AJ is 158 - 80 = 78º

If a boy 5 feet tall casts a shadow 14 feet long, what will be the length of the shadow of a tree that is 25 feet high?
Answer:
70 feet
Step-by-step explanation:
This problem can be answered by using proportions based on similar triangles.
Notice that a person and its shadow on the ground form a right angle (therefore they can be considered the two "legs" of a right angle triangle)
The same runs for the tree and its shadow.
Since the inclination of the rays of the sun are the same at the same time for both objects (the boy and the tree), their hypothenuses form the same angles with the ground and therefore belong to similar triangles.
We can create the following proportion to solve for the shadow of the tree (ST) using the information provided: the height of the boy (HB), the shadow of the boy (SB), and the height of the tree (HT)
[tex]\frac{SB}{HB} =\frac{ST}{HT}\\\frac{14}{5} =\frac{ST}{25}\\\frac{ST}{25}=\frac{14}{5} \\ST=\frac{14*25}{5}\\ST=70\,\,ft[/tex]

ry=–x(x, y) → (–y, –x)
ry=x(x, y) → (y, x)
ry=–x(x, y) → (y, x)
Answer:
R(y=x) = (x, y) → (y, x)
Step-by-step explanation:
The coordinates of A are (-2, 1).
The coordinates of A' are (1, -2).
Clearly, the values have been swapped in accordance with ...
(x, y) → (y, x)

What is an angle?In mathematics and geometry, an angle is a measure of the amount of rotation or turn between two lines or line segments that meet at a common endpoint, called the vertex of the angle.
Angles are typically measured in degrees (°) or radians (rad).
A full rotation around a point is 360 degrees or 2π radians.

Examine the diagram.
A triangle has angles A, 60 degrees, 55 degrees. A line is at the top of the triangle and forms angles B, C, and 65 degrees. Angle C is opposite to angle with measure 60 degrees.
The diagram shows parallel lines cut by two transversal lines creating a triangle. Which statement can be made from the diagram?
mAngleB + mAngleC + 55° = 180°
mAngleA + 60° + 55° = 180°
mAngleC = 55°
mAngleA = 55°
Answer:
mAngleA + 60° + 55° = 180°Step-by-step explanation:
As two angles of the triangle are 60° and 55°, the measure of ∠A is:
180° - (60° + 55°) = 65°So the angles C and B measure 60° and 55°.
∠C is opposite to 60°, so is 60° as well, therefore m∠B = 55°

mAngleB + mAngleC + 55° = 180°

Answer:
x=15(1/3√y)
Step-by-step explanation:
X varies indirectly with the cube root of y
x=k/3√y
x=3 when y=125
3=k/3√125

which two functions are inverses of each other
Answer:
f(x) = 4x, g(x) = [tex]\frac{1}{4}x[/tex]
Step-by-step explanation:
Inverse function is when you switch the x and the y and solve for x
f(x) = 4x
y = 4x
x = 4y
Now solve for x
y = [tex]\frac{1}{4}x[/tex]
g(x) = [tex]\frac{1}{4}x[/tex]
If you try that with the other functions, none of them work.
Answer:
C. f(x)= 4x, g(x)= 1/4x
Step-by-step explanation:
inverse functions are flipping x and y corrdinates so let's plug in x=1 into f(x) and get y = 4

A spinner has four equal sections, with one letter from the word "MATH" in each section.
Type your response in each blank below.
1. You spin the spinner 20 times. About how many times do you expect it will land on A?
2. You spin the spinner 80 times. About how many times do you expect it will land on something other than A?
Explain your reasoning.
Answer:
1. 5 times
2. 60 times
Step-by-step explanation:
there is only one a so its 1/4 times 20 and 4 because that is the total
20/4= 5
there is 3 because there is letters that are not a
3/4 times 80
240/4
1. The number of times expected that should be landed on A should be 5 times.
2. The number of times expected should be 60 times.
Calculation of the number of times:1. Since A spinner has four equal sections, with one letter from the word "MATH" in each section.
So, here the number of times should be
= [tex]20\div 4[/tex]
= 5
2. The number of times should be
[tex]= 3/4 \times 80\\\\= 240\div 4[/tex]

find points of discontinuity y=x-8/x^2+6x-7
Answer:
Step-by-step explanation:
You'll need to use parentheses here to remove ambiguity regarding what's in your denominators:
x - 8 x - 8
y = ------------------ = -----------------
x^2 + 6x - 7 (x + 7)(x - 1)
This last result becomes undefined at x = -7 and x = 1, and thus its graph is discontinuous at those x- values.
The points of discontinuity is x = -7, x = 1
Use parentheses to remove ambiguity considering the denominators
[tex]y=x-8/x^{2} +6x-7[/tex]
= x-8 ÷ (x+7)(x-1)
The result becomes undefined at x = -7
and x = 1,
thus its graph is discontinuous at those x values.

Answer:
[tex]V=150cm^3[/tex]
Step-by-step explanation:
First we need to find area of the triangle with a base of 4 cm and a height of 5cm, and then multiply that by the length of the prism of 15cm.
The area of the triangle is given by the formula:
[tex]A_T=\frac{bh}{2}[/tex]
where b is the base: [tex]b=4cm[/tex] and h is the height: [tex]h=5cm[/tex]
thus, in this case we have:
[tex]A_T=\frac{(4cm)(5cm)}{2}\\ \\A_T=\frac{20cm^2}{2} \\\\A_T=10cm^2[/tex]
And now, the volume will be the area of the triangle multiplied by the length [tex]l=15cm[/tex] of the prism:
[tex]V=A_T*l[/tex]
Substituting the known values:
[tex]V=10cm^2*15cm\\V=150cm^3[/tex]
The volume in cubic centimeters is 150.
