Answer:C
Step-by-step explanation:
A baseball diamond is a square with sides 90 ft long. A batter is at bat, with runners
at first and second base. At the moment the ball is hit, the runner at first base runs to
second base at 25 ft/s. Simultaneously, the runner on second base runs to third base
at 15 ft/s. How fast is the distance between these two runners changing 2 s after the
ball is hit?
The runner on first has distance from second of 90 -25t, where t is the time in seconds since he left 1st base.
The runner on second has a distance from second of 15t, where t is the time in seconds since he left 2nd base
Then the Pythagorean theorem tells us the distance between the runners is :
d = √((90 -25t)² +(15t)²)
The rate of change of distance between the runners is the derivative of this with respect to time.
dd/dt = 2(90-25t)(-25)+2(15t)(15) / (2sqrt(90-25t)^2 + 15t^2)
Replace t with 2 and solve to get: -31
The distance between runners is decreasing at 31 ft/s two second after they leave the bases.

Two new wind-farm tower projects are proposed for a small company that installs them in south western Pennsylvania. Project A will cost $250,000 to complete and is expected to have an annual net cash flow of $75,000. Project B will cost $150,000 to complete and should generate annual net cash flows of $52,000. As a small company, the owner and senior management team are very concerned about their cash flow. Use the payback period method and determine which project is better from a cash flow standpoint. Show your work and include any formulas used to calculate PP.
Answer:
Step-by-step explanation:
The payback period is the time to regain the cost of the investment or DRCI. It is a risk criterion that measures the time needed for the discounted sum of the forecast cash flows to allow the recovery of the cost incurred by the investment. However, the shorter the payback period, the lower the risks associated.
Mathematically;
Payback period = Cost of the investment / Annual Net Cash Flow
From the given question:
For project A;
Cost of investment = $250,000
Annual net Cash Flow = $75000
The payback period for Project A = $250,000 / $75,000
The payback period for Project A = 3.33
For project B;
Cost of investment = $150,000
Annual net Cash Flow = $52000
The payback period for Project A = $150,000 / $52,000
The payback period for Project A = 2.88
Thus, from the calculation, we can deduce that project B is better than project A because there fewer risks associated with it because it has a shorter payback period compared to project A.

How do you think you could represent the number 2,300 as a number times a multiple of 10?
Answer:
23,000
Step-by-step explanation:
A manufacturing company produces electric insulators. You define the variable of interest as the strength of the insulators. If the insulators break when in use, a short circuit is likely. To test the strength of the insulators, you carry out destructive testing to determine how much force is required to break the insulators. You measure force by observing how many pounds are applied to the insulator before it breaks. You collect the force data for 30 insulators selected for the experiment and find out that the mean force is 1670. The population mean force that you try to estimate is_______.
a. a confidence interval.
b. a statistic.
c. a point estimate.
d. a parameter.
e. an interval estimate.
Answer:
b. a statistic.
Step-by-step explanation:
the value 1670 is regarded as a statistic. this is because it is a representation of the value of a sample. from the question we get that destructive testing is being done this shows is that what we have here is a sample.
the mean force 1670 is not a parameter, a point estimate, a confidence interval or interval estimate. therefore option b is the answer.

Write the slope-intercept form for the equation of a line parallel to y = -9 and passes through the point (12, -5)
Answer:
Let's see what to do buddy...
_________________________________
Step-by-step explanation:
_________________________________
STEP (1) :
The slope of the line y = - 9 is 0(zero) because it is a Horizontal line.
So the slope of the line which is parallel to y = -9 is zero .
_________________________________
STEP (2) :
We have this equation to find the slope-intercept form of the linear functions :
[tex]y - y(given \: point) = (slope) \times ( \: x -x(g \: p) \: ) \\ [/tex]
_________________________________
STEP (3) :
Now it is time to put the slope and the given point in the equation :
given point = ( 12 , -5 )
slope = 0
[tex]y - ( - 5) = 0 \times (x - 12) \\ \\ y + 5 = 0 \\ \\ y = - 5[/tex]
_________________________________
And we're done.

How many solutions does the equation have? How do you know?
6x – 2 = 2(3x – 1)
Answer:
infinite solutions
Step-by-step explanation:
First, solve the equation.
6x - 2 = 2(3x - 1)
6x - 2 = 6x - 2
By this point, no further work needs to be done because you have your answer. If these two equations are the exact same and are equal to each other, then there is an infinite number of solutions for x.
This is what'll happen if you continue to solve for x:
6x = 6x
x = x
This is infinite because if you substitute any real number, the equation is true.
For example: 1 = 1 or 176 + 59 = 176 + 59.

A statistics instructor wants to see if allowing students to use a notecard on exams will affect their overall exam scores. The instructor thinks that the results could be affected by the type of class: traditional, Web-enhanced, or online. He randomly selects half of his students from each type of class to use notecards. At the end of the semester, the average exam grades for those using notecards is compared to the average for those without notecards.
Required:
a. What type of experimental design is this?
b. What is the response variable in this experiment?
c. What is the factor that is set to predetermined levels? What are the treatments?
d. Identify the experimental units.
Answer:
Throughout the clarification section elsewhere here, the definition of the concern is discussed.
Step-by-step explanation:
This seems to be an experimental analysis where the students were purposely administered an assessment and treatment of someone using notecards towards examine a potential improvement in the answer or calculated indicator that is average scores. Overall test scores are the answer component. Through the use of notecards seems to be the explanatory component. The vector degree is 'Used' either 'Not Used.' The participants offering the test seem to be the experimental groups.She paid with a $100 bill and received $32.16 in change.

15. A student graphed f(x) = x and g(x) = f(x) + 3 on the same coordinate grid. Which
statement describes how the graphs of fand g are related?
A. The graph of f is shifted 3 units up to create the graph of g.
B. The graph of f is steeper than the graph of g.
C. The graph of f is shifted 3 units down to create the graph of g.
D. The graph of f is less steep than the graph of g.
Answer:
The graph of f is shifted 3 units up to create the graph of g.
Here we have a problem with translations, where we define a translation as an operation that moves the graph of a function in a given direction.
We will see that the correct option is A.
"The graph of f is shifted 3 units up to create the graph of g."
To get this, we first need to describe vertical translations.
For a function f(x) we define a vertical translation (or vertical shift) of N units as:
g(x) = f(x) + N
If N is positive, the translation is upwards
if N is negative, the translation is downwards.
So here we have:
g(x) = f(x) + 3
So we can see that this is a translation of 3 units upwards, then the correct option is A, the graph of f(x) is shifted (or translated) 3 units up to greater the graph of g(x).
And the graphs of g(x) = x + 3 and f(x) = x can be seen below, where you can see this, where the grey line is g(x).

One hundred students go to the cafeteria to eat lunch. Six tables held the same amount of students while an additional 10 students stood in line. Which equation can be used to find the number of students sitting at each table?
Answer:
6x + 10 = 100
Step-by-step explanation:
Given
Six tables held the same amount of students
let the number of student held by 1 table = x
since there are 6 table holding same number of students
number of student held by 6 table = 6*x = 6x
given that
number of students held in a line = 10
therefore
total number of students = number of student held by 6 table + number of students held in a line
total number of students in cafeteria = 6x + 10
also given
One hundred students go to the cafeteria to eat lunch
6x + 10 = 100
6x = 100 - 10 = 90
x = 90/6 = 15
thus,
the number of student held by 1 table = 15
thus, required equation can be used to find the number of students sitting at each table is 6x + 10 = 100

The national debt was about $6.9 trillion at the end of 2003. Express this quantity as the number of dollars per person. Assume a U.S. population of 280 million.
Answer:
$24642.85 per person.
Step-by-step explanation:
6.9T/280M
The average amount of debt on each person in U.S is $24,642.86.
What is average?An average is a single number taken as representative of a list of numbers, usually the sum of the numbers divided by how many numbers are in the list.
Total debt = $6.9 trillion = $6.9 * [tex]10^{12}[/tex]
Total population = 280 million = 280 * [tex]10^{6}[/tex]
