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.
Answers
Answer:
c cuz differential of position is velocity, velocity is negative so moving away, differential of velocity is acceleration, negative acc is decreasing velocity
The candy produced by a company has a sugar level that is normally distributed with a mean of 16.8 grams and a standard deviation of 0.7 grams. The company takes readings of every 10th bar off the production line. The reading points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4. Is the process in control or out of control and why?
Answers
Answer:
It is not in control because at least two of the of the data points are more than 2 standard deviations from the mean are far apart.
18.3,18.4 > 18.2 Upper Control limit
14.9, > 15.4 Lower Control Limit
Step-by-step explanation:
Find the limits using μ ± 3σ and μ ± 2σ
Using μ ± 3σ
Upper Control Limit = μ + 3σ = 16.8 + 3(0.7)= 16.8 + 2.1= 18.9
Lower Control Limit = μ - 3σ =16.8 - 3(0.7)= 16.8 - 2.1= 14.7
Using μ ± 2σ
Upper Control Limit = μ + 2σ = 16.8 + 2(0.7)= 16.8 + 1.4= 18.2
Lower Control Limit = μ - 2σ =16.8 - 2(0.7)= 16.8 - 1.4= 15.4
The data points are 17.3, 14.9, 18.3, 16.5, 16.1, 17.4, 18.4.
Rearranging these data points 14.9, 16.1, 16.5, 17.3, 17.4, 18.3,18.4.
We see from the above that it is out of control because the values jump above and below the mean.
It is not in control as two of the of the data points are more than 2 standard deviations from the mean are far apart.

Given six consecutive integers with a sum of seven times the
second number, write an algebraic equation for this situation.
Answers
Answer:
x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)
Step-by-step explanation:
Equations
The situation can be written as an algebraic equation by setting the variables as follows:
x = first integer
x + 1 = second integer
x + 2 = third integer
x + 3 = fourth integer
x + 4 = fifth integer
x + 5 = sixth (and last) integer
The sum of all six numbers must be equal to 7 times the second number, thus:
x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 = 7(x + 1)

Need help I need to do this right now!
Answers
Answer: Okay, well first lets find the quotient 345 ÷ 8:
It is 43. 125, but we're going to simplify it to 43
Now this is the really easy part, so lets find a number greater than 43, which would be 44.
Now that we have that, we need to find a decimal that's lower than 43, which would be 42.
So our numbers would be 44 and 42.

The Valley High School student council is planning a dance. The
school has 480 students. The lowest possible ticket price is $3.00,
and they estimate that for every $0.20 increase in ticket price, 20 fewer
students will attend. What ticket price will maximize
the student council's profit?
SELECT ONE OPTION BELOW:
$4.20
$3.90
$3.50
$4.00
Answers
Answer:
$3.90
Step-by-step explanation:
its B
The price of the ticket at which the student councils will maximize the profit is $3.90.
Option B is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Number of students = 480
Lowest ticket price = $3
Ticket price = $4.20
This means,
4.20 - 3 = 1.20
There is an increase of $1.20 which is 0.20 x 6 = $1.20.
The number of students who attended when the ticket price is $4.20.
= 480 - (6 x 20)
= 480 - 120
= 360
Profit:
= 360 x 4.20
= $1512
Ticket price = $3.90
This means,
3.90 - 3 = 0.90
There is an increase of $0.90 which is 0.20 x 4.5 = $0.90.
The number of students who attended when the ticket price is $3.90.
= 480 - (4.5 x 20)
= 480 - 90
= 390
Profit:
= 390 x 3.90
= $1521
Now,
Ticket price = $3.50
This means,
3.50 - 3 = 0.50
There is an increase of $0.50 which is 0.20 x 2.5 = $0.50.
The number of students who attended when the ticket price is $3.50.
= 480 - (2.5 x 20)
= 480 - 50
= 430
Profit:
= 430 x 3.50
= $1505
Now,
Ticket price = $4.00
This means,
4 - 3 = 1
There is an increase of $1 which is 0.20 x 5 = $1.
The number of students who attended when the ticket price is $4.20.
= 480 - (5 x 20)
= 480 - 100
= 380
Profit:
= 380 x 4.20
= $1520
We see that,
The profit is highest when the ticket price is $3.90.
Thus,
$4 ticket price will maximize the student council's profit.
