Answer:
C is the correct answer.
Step-by-step explanation:
first look at the first "kite". You got to times 30.5 x 4 ,since all of the sides are equal to each other. If you do the you will get (122).
Now onto the next one. you got to do the same but instead you got to times 40.75 x 2, and you'll come up with (81.5). Then you need to take the other number and do the same. 20.25 x 2, and that will equal to (40.5).
When you get those numbers you need to add them. So, 81.5 + 40.5= 122.
In the end you'll end up with C.
And when they ask for "What did he do wrong?"
He didn't do anything wrong, they are just trying to throw you off.

If f(x)=x^3-x, what is the average of change of f(x) over the interval [1,5]
Answers
Given:
The function is:
[tex]f(x)=x^3-x[/tex]
To find:
The average of change of f(x) over the interval [1,5].
Solution:
We have,
[tex]f(x)=x^3-x[/tex]
At x=1, we have
[tex]f(1)=(1)^3-(1)[/tex]
[tex]f(1)=1-1[/tex]
[tex]f(1)=0[/tex]
At x=5, we have
[tex]f(5)=(5)^3-(5)[/tex]
[tex]f(5)=125-5[/tex]
[tex]f(5)=120[/tex]
The average of change of f(x) over the interval [a,b] is
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Now, the average of change of f(x) over the interval [1,5] is
[tex]m=\dfrac{f(5)-f(1)}{5-1}[/tex]
[tex]m=\dfrac{120-0}{4}[/tex]
[tex]m=\dfrac{120}{4}[/tex]
[tex]m=30[/tex]
Therefore, the average of change of f(x) over the interval [1,5] is 30.
a) What type of correlation is shown in diagram A?
b) What type of correlation is shown in diagram B?
c) What type of correlation is shown in diagram C?
Answers
Answer:
A = strong negative correlation
B = positive correlation
C = very weak or no correlation
Step-by-step explanation:
Scatter plot A:
A clear linear trend line could be observed having a negative slope ; the nature of the slope gives the nature of the correlation (positive or negative). Since the slope is negative then we have a negative correlation. The linear trend line is almost straight with only few points marginally missing the best fit line. Hence. We can conclude to have a strong negative correlation.
Scatter plot B :
Has a positive slope, and hence a positive correlation. The best fit line miss a few points but the linear trend of the plot is still observable. Hence, we can conclude to having a fairly strong positive correlation.
Scatter plot C :
From the graph, no linear trend can be observed and hence it is fit to say that no correlation exists between the points.

A mass weighing 9 lb stretches a spring 1.5 in. The mass is displaced 5 inch in the downward direction from its equilibrium position and released with no initial velocity. Assuming that there is no damping, and that the mass is acted on by an external force of 5 cos(6t) lb, solve the initial value problem describing the motion of the mass. For this problem, please remember to use English units: ft, lb, sec.
Answers
Answer:
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]
Step-by-step explanation:
Given
[tex]w =9lb[/tex] --- weight
[tex]L = 1.5in[/tex] --- stretch
[tex]u(0) =5in[/tex] --- initial position
[tex]u'(0) =0[/tex] --- initial velocity
[tex]\gamma =0\ lbs/ft[/tex] --- no damping
[tex]F(t) = 5cos(6t)\ lb[/tex] -- External force
Required
Solve the initial value problem
The initial value problem is calculated using:
[tex]mu" + ku = F(t)[/tex]
First, convert all lengths to ft
[tex]L = 1.5in[/tex]
[tex]L = \frac{1.5}{12}ft[/tex]
[tex]L = \frac{1}{8}ft[/tex]
[tex]u(0) =5in[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex]
Weight is calculated as:
[tex]w = mg[/tex] and [tex]w = kL[/tex]
Where
[tex]g = 32fts^{-1}[/tex]
Make m the subject in [tex]w = mg[/tex]
[tex]m = \frac{w}{g}[/tex]
[tex]m = \frac{9}{32}[/tex]
Make k the subject in [tex]w = kL[/tex]
[tex]k = \frac{w}{L}[/tex]
[tex]k = \frac{9}{1/8}[/tex]
[tex]k = 72[/tex]
Recall that: [tex]mu" + ku = F(t)[/tex]
[tex]\frac{9}{32}u" + 72u = 5cos(6t)[/tex]
Multiply through by 32
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]
Joanna is reading a storybook. The ratio of the number of pages she read to
the pages that remain to be read is 7:3. If the book contains 500 pages in all,
how many pages did Joanna read and how many pages remain to be read?
Answers
Answer:
The amount of pages that remain to be read is 150 pages
Step-by-step explanation:
Okay if we know it's in 7:3 ratio we can easily add them both to get 10, then divide 10 by 500 to get 50. SO we now know that 50 is 1 unit and since the ratio says 3 units is the answer, we multiply 50 by 3 to get 150.
The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?
Answers
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8

A flight with 104 passengers takes off at 1:15. The plane travels 560 miles in 1 hour. At that speed, how far will the plane travel in 3 hours? What information is needed to answer the question?
Answers
Answer:
To find how far the plane will travel, we need the time and length it traveled previously to form the MPH (miles per hour)
Using this information we can make an equation
560/1 = 560 miles in 1 Hour
x/3 = X miles in 3 Hours
560/1 = X/3
X= 1680
