Answer:
A, undefined
Step-by-step explanation:
The general rule is that vertical lines are undefined slope, because there's literally no change in x values. The vertical line test also fails, meaning there is no slope. Horizontal lines have a slope of 0, while vertical lines don't own any numbers that are important except for x-axis numbers.
If you do y2-y1 over x2-x1, you literally get 1/0 which is nothing. 0/1 = 0, but 1/0 is nothing.
Hope this helps!

A structural steel fabricator cuts 25 pieces each 16.2 centimeters long from a 6.35-meter length
of channel iron. Allowing 4 millimeters waste for each piece, find the length in meters of
channel iron left after all 25 pieces have been cut.
Answers
Answer: 2.2 meters
Step-by-step explanation:
The data is:
The initial piece is 6.35 meters long.
We cut 25 pieces of 16.2cm each, so in pieces only we have:
25*16.2cm = 405cm
1m = 100cm
Then: 405cm = (405/100) m = 4.05m
And each time that we cut a piece, we have 4mm of waste.
Then we have 25 times the 4mm of waste, this means that the total waste is:
4mm*25 = 100mm
and 1000mm = 1m
100mm = (100/1000) m = 0.1m
So the total amount that was cut is:
4.05m + 0.1m = 4.15m
The length in the channel iron will be: 6.35m - 4.15m = 2.2 meters
Consider the linear second-order differential equation:
d^2y/ dx^2 + a1(x)dy/dx +ao(x)y(x)=0
Note that this equation is linear because y(x) and its derivatives appear only to the first power and there are no cross terms. It does not have constant coefficients, however, and there is no general, simple method for solving it like there is if the coefficients were constants. In fact, each equation of this type must be treated more or less individually. Nevertheless, because it is linear, we must have that if y1(x) and y2(x) are any two solutions, then a linear combination.
y(x)=c1y1(x)+c2y2(x) where c1 and c2 are constants, is also a solution. Prove that y(x) is a solution.

10 less than three times a number is 23. Find the number
Answers
Answer:
x = 11
Step-by-step explanation:
23 = 3x-10
1. Add 10 to both sides of the equation. -10 plus 10 is equal to zero so it cancels out to nothing, and 23 plus 10 is 33.
2. The new equation is now 33 = 3x.
3. Now you want to divide both sides by 3 to make x by itself since that is what you are trying to solve for.
4. 33/3 is equal to 11 so x = 11.
The value of the unknown number is 11
Inequality is a concept in mathematics that shows the comparison between two non-equal numbers.
From the given information
Let the unknown number be x∴
3x - 10 = 23
Collect like terms
3x = 23 + 10
3x = 33
Divide both sides by 3
[tex]\mathbf{\dfrac{3x}{3}= \dfrac{33}{3}}[/tex]
x = 11

An oblique prism has a volume of 144 cubic units. The area of its base is 24 square units.
What is the perpendicular height of the prism?
2 units
4 units
6 units
8 units
Answers
Answer:
6
Step-by-step explanation:
the volume of a prism is always the base times the height this can be written as V = bh
we know the volume is 144 and the base is 24
substitute this into your equation: 144 = 24h
divide both sides by 24 to find h
144 ÷ 24 = 6
so you get h = 6
Assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.
Perpendicular height of the prismUsing this formula
Volume of prism=Base area ×Height
Hence:
144=24×h
h=144/24
h=6 units
Therefore, assuming an oblique prism has a volume of 144 cubic units. The perpendicular height of the prism is 6 units.

a lacrosse ball has 200 j of kinetic energy . how much kinetic energy does it have if it is thrown 3 times faster? how much more will it hurt if that ball hit you
Answers
Answer:When you change the position and speed of the ball in the carnival
game, you transfer energy to the ball. Energy is the ability of a person
or an object to do work or to cause a change. When you do work on an
object, some of your energy is transferred to the object. You can think
of work as the transfer of energy. In fact, both work and energy are
measured in the same unit, the joule.
The man in the photograph above converts one form of energy
into another form when he uses his muscles to toss the ball. You can
think of the man and the ball as a system, or a group of objects that
affect one another. Energy can be transferred from the man to the
ball, but the total amount of energy in the system does not change

C. y = 4x + 18
D. y = 4x - 42

Answers
Answer:
A
Step-by-step explanation:
Slope intercept form is y = mx + b
First find the slope or m with this equation [tex]\frac{y2 - y1}{x2 - x1}[/tex] (plug in) [tex]\frac{6 - 2}{12 + 4}[/tex] = [tex]\frac{4}{16}[/tex]= [tex]\frac{1}{4}[/tex]
So your slope is [tex]\frac{1}{4}[/tex]
To find the y-intercept you use y= mx + b and plug in.
6 = 1/4(12) + b
6 = 3 + b (minus 3 on both sides)
3 = b
so 3 is the y-intercept

A) -1
B) 1
C) 3
D) -3
Answers
Answer:
C. 3
Step-by-step explanation:
Zero of a function is the point where the line of the function crosses the x-axis. At this point, y = 0. In simple terms, it is the value of x (input value) that will give us a y-value (output value) of zero.
In the graph of the function given above, the line intercepts the x-axis at 3. When x = 3, y = 0.
Therefore, the zero of g is 3.

{A} is order.
{B} is order.
{C} is order.
For example, zero, half, first, second, third, etc. (If it is negative, you would write, negative first, negative second, etc)
Answers
Answer:
The reaction is second order in A(g), first order in B(g) and zero order in C(g)
Step-by-step explanation:
A non elementary reaction is a reaction that does not take place in a single reactive encounter. This implies that the reaction occurs in steps as shown in the question above.
C(g) is an intermediate, hence it does not occur in the overall reaction equation. The overall reaction equation is: 2A(g) + B(g) ---> 2D(g)
The rate law of the rate determining step is obtained from;
Rate= k1[A] [B] for fast step
Rate= k2 [A] [C] for slow step
But rate of forward reaction = rate of reverse reaction
k1[A] [B] = k-1 [C]
But [C] =k1 [A] [B]/k-1
Hence
Substitute into
Rate = k2 [A] [C]
Rate = k2k-1[A]^2 [B]/k-1
But k2k-1/k = K
Hence;
Rate = K [A]^2 [B]
The answer is when The reaction is second order in A(g), first-order in B(g), and zero-order in C(g)
Step-by-step explanation:
Elementary reactionWhen A non-elementary reaction is a reaction that does not take place in a single reactive encounter. also, This implies that the reaction occurs in steps as shown in the question above.
Then C(g) is an intermediate, hence it does not occur in the overall reaction equation. also The overall reaction equation is: 2A(g) + B(g) ---> 2D(g)
Then The rate law of the rate-determining step is obtained from;
After that Rate= k1[A] [B] for fast step
Then Rate= k2 [A] [C] for slow step
But rate of forward reaction = rate of reverse reaction
k1[A] [B] = k-1 [C]
But [C] =k1 [A] [B]/k-1
Hence
Then Substitute into
Rate = k2 [A] [C]
Rate = k2k-1[A]^2 [B]/k-1
But k2k-1/k = K
Hence;
Thus, Rate = K [A]^2 [B]

Range is the difference between the highest score and the lowest score.
Given the following scores on the Overcontrolled-Hostility scale.
69, 84, 56, 89, 47, 63, 86, 58, 74, 35, 71, 60
From the data:
Highest score = 89
Lowest score = 35
Range = Highest score - Lowest score
Range = 89-35
Range = 54
Hence the possible value of the range is 54
For the scores on the Defensiveness scale given as:
38, 70, 35, 42, 26, 87, 74, 61, 69, 46, 63, 25
Highest score = 87
Lowest score = 25
Range = Highest score - Lowest score
Range = 87-25
Range = 62
Hence the possible value of the range is 62
