The position of a particle moving along the x-axis is given by a twice-differentiable function x(t). If x(2) < 0, x'(2) < 0, and x''(2) <0, which of the following statements must be true about the particle at time t=2?
a. The particle is moving toward the origin at a decreasing speed.
b. The particle is moving toward the origin at an increasing speed.
c. The particle is moving away from the origin at a decreasing speed.
d. The particle is moving away from the origin at an increasing speed.
e. The particle is moving away from the origin at a constant speed.
Answer:
c. The particle is moving away from the origin at a decreasing speed.
Step-by-step explanation:
Since x(2) which represents the particles position is less than zero, that is, x(2) < 0, it shows that the particle is at the left of the origin at t = 2.
Also, x'(2) which represents the particle's speed at t = 2 is less than zero, that is, x(2) < 0, the particles speed is negative at t = 2.
Finally, since x"(2) which represents the particle's acceleration at t = 2 is less than zero, that is, x"(2) < 0, the particle's acceleration is negative at t = 2 and thus decreasing.
So, combining these three conditions together shows that the particle is moving away from the origin at a decreasing speed at time, t = 2.
Since [tex]x(2)[/tex], which represents the subatomic particle location, is below zero, that is, [tex]x(2) <0[/tex], it indicates that the particles are to the left of the origin at [tex]t = 2.[/tex]
Therefore, [tex]x'(2)[/tex], which represents the particle's speed at [tex]t = 2[/tex], is less than zero, implying that[tex]x(2) <0[/tex], the subatomic particle speed at [tex]t=2[/tex], is negative.Furthermore, because [tex]x"(2)[/tex], which represents that particle's acceleration at [tex]t = 2[/tex], is less than zero, [tex]x"(2)< 0[/tex], the particle's acceleration at [tex]t = 2[/tex] is negative and consequently declining.Considering these three requirements reveals that at the moment [tex]t = 2[/tex], the particle is moving away from the nucleus at a decreasing speed.Therefore, the answer is "Option C".

Because your Christmas tree is bigger this year, you can decorate it with more ornaments! Last year, you put 35 ornaments on the tree. Since the tree is now bigger, you have room to increase the number of ornaments by 40%.
a. How many more ornaments can you put on the tree?
b. What is the total number of ornaments you are putting on the tree this year?
Answer:
You can put a total of 14 more ornaments this year.
The total number of ornaments you can put are 35+14= 49
Step-by-step explanation:
Answer:
See below :)
Step-by-step explanation:
a. This year, we know that the space increased by 40% of the last years.
Last year: 35 ornaments
This year: 35 ornaments + 40%(35) ornaments
We want to calculate 40%(35) so:
35 * 0.4 = 14
a answer. I can put 14 more ornaments on the tree.
b. In order to calculate the total ornaments, we want to add last year's + the new space
We already calculated 40%(35) is 14 so all we have to do is add 35 and 14:
35 + 14 = 49
b answer. The total number of ornaments I can put on the tree this year is 49.
Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)
(y-4) = 2(X+1)
Step-by-step explanation:
Hey there!
The given eqaution is; y = 2x-5.......(i)
Now; As the eqaution is in the form of y= mx+b.
Slope(m1) = 2.
As per the condition of parallel lines, slope of the 1st equation (m1) = slope of 2nd eqaution (m2).
Therefore, m1= m2= 2
Now, use one point formula for finding the eqaution of the line which passes through the point.
(y-y1) = m2(x-x1)
~ Put all values.
(y-4) = 2(X+1)
You can simply write upto here. But it you want to make it simplified form then, (look below)
~ simplify it.
y = 2x +2+4
The eqaution of the line which is parallel to y = 2x -5 and point (-1,4) is y = 2x + 6.
Hope it helps.....
Answer: y - 4 = 2(x + 1)
Step-by-step explanation:
The point slope form formula says that y - b = m(x-a) where m is the slope,b is the y coordinate of a given point , and a is the x coordinate of the same point.
Remember that parallel lines have the same slopes but different y-intercepts, meaning that m will equal to 2 because the slope for the line y=2x-5 is 2.
m will be 2, b will be 4 , and a will be -1.
y - 4 = 2(x - (-1) which reduces to
y - 4 = 2(x + 1)

Answer:
Angle 1 is 140.
Step-by-step explanation:
Set angle 1 and angle 3 equal to each other since they are congruent to each other to get this equation 20x+60=30x+20. Subtract 20x on both sides to get this equation 60 = 10x + 20. Subtract 20 on both sides to get to 40 = 10x. Divide 10 on both sides to get your x-variable which is 4. Since you are solving for angle 1, plug in the x-value to get 20(4)+60. You should get 140 degrees as your final answer.
g(x)=x^2-3 and h(x)=2x+5
find h(g(x))
We know that [tex]g(x) = x^2-3[/tex] and [tex]h(x) = 2x+5[/tex]. So, [tex]h(g(x))[/tex] is equal to [tex]h(x^2-3)[/tex], which is [tex]2(x^2-3)+5[/tex]. This can be simplified to [tex]2x^2-1[/tex].

Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m
The speed of a wave is the product of the wavelength and its frequency.
The speed of the wave is 20m/s
Given
[tex]\lambda = 10m[/tex] --- the wave length
[tex]f =2Hz[/tex] --- the frequency
[tex]A = 3m[/tex] --- the amplitude
The speed of wave (v) is calculated as follows:
[tex]v =f\lambda[/tex]
Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]
[tex]v = 2Hz \times 10m[/tex]
[tex]v = 20ms^{-1}[/tex]
Hence, the speed of the wave is 20m/s

Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
Answer:
The result of the correct substitution gives:
x = 3/7 and y = 27/7
Step-by-step explanation:
From the given information:
y = 2x + 3 ---- (1)
3x + 2y = 9 ---- (2)
By using substitutional method
Substitute the value of y = 2x +3 into equation (2)
So,
3x + 2(2x + 3) = 9
3x + 4x + 6 = 9
7x = 9 - 6
7x = 3
x = 3/7
From equation (1), let replace the value of x to be 3/7
So,
y = 2x + 3
y = 2(3/7) + 3
y = 6/7 + 3
y = 27/7

Some people have been complaining that the children's playground at a municipal part is too small and is in need of repair. Managers iof the pard decide to survey city residents to see if they believe the playground should be rebuild. They hand out questionnaires to parents who bring children to the park and asked: "Do you think the playground should be repaired and expanded even if that means raising the entrance fee to the park?" Which type of bias is most likely to have occurred in this situation?
a
Voluntary Bias
b
Wording Bias
c
Response Bias
d
Non-Response Bias
Answer:
c . Response Bias
Step-by-step explanation:
This is a convenience sampling and it could lead us to a response bias. Those parents who bring their children to play in the park would most likely to support rebuilding the park while the parents those who do not bring their children would not be sampled and thus would not be included in the sampling. This sample method involved is not representative of the entire population. So it is a responsive bias.

You purchased concentrated cleaner that must be diluted (watered down) before use. Container A is the cleaner, which is a 20% solution. Container B is pure water. You are mixing together the contents of Container A and Container B to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution? Write your answers as integers only.
Container A: 20% Cleaning Solution =
gallons
Container B: Pure Water =
gallons
Answer:
Amount of chemical solution = 18 gallon
Amount of pure water = 22 gallon
Step-by-step explanation:
Assume;
20% of solution = x
So,
Amount of pure water = 40 gallons - x
Amount of pure water = 40 - x
Computation:
20% of x = 9% of 40 gallon
0.2 x = 3.6
x = 3.6 / 0.2
x = 18 gallon
So,
Amount of chemical solution = 18 gallon
Amount of pure water = Total solution - Amount of chemical solution
Amount of pure water = 40 -18
Amount of pure water = 22 gallon

The expression 2y + 2.6 is equal to ? for y = 1.4
Answer:
5.4 :))
Step-by-step explanation:
ok so first you take 2*1.4=2.8 (you replace the Y with the number)
so now you have 2.8+2.6 which is equal to 5.4
Answer:
5.4
Step-by-step explanation:
2*1.4 is 2.8. Now the expression is y2+2.6=. Now, that we figured out what 2y is, which is 2.8, we need to add on 2.6. 2.6 + 2.8 is equal to 5.4. Now, to write out the whole equation, it would look like this.
2y+2.6=?
y2+2.6=?
2.8+2.6=?
5.4
So in the end:
2y+(2.6)= 5.4
