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".

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.
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

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

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.
Each week as part of her workout, Monica walks 0.5 mile, runs 1.6 miles, and then walks 0.75 mile.
How many total miles will Monica walk and run in a year? Reminder: there are 52 weeks in a year.
Answer:
She will walk and run 148.2 miles in a year
Step-by-step explanation:
She walks: 0.75+0.5=1.25 miles each week
And: 1.25 *52=65 miles a year
She runs : 1.6 miles a week
And: 1.6*52 =83.2 miles a year
Total miles : 83.2+65=148.2 miles

choice that shows the correct setup for long division and answer.
O A. 12)2.568 = 0.214
O B. 12) 2.568 = 2.14
O c. 12)
25.68 = 2.41
O D. 12) 25.68 = 2.14
SUBMIT
Answer:
D. 12) 25.68 = 2.14
Step-by-step explanation:
Given :
Divisor = 1.2
Dividend = 2.568
We can make the divisor a whole number by multiplying the divisor by 10,
i.e. Divisor = 1.2 x 10 = 12
Similarly , dividend = 2.568 x 10 = 25.68
Therefore,
2.14
12 | 25.68
(-) 24
16
(-) 12
48
(-) 48
0
Hence the answer is 2.14
