Show that an implicit solution of 2x sin2(y) dx - (x2 + 11) cos(y) dy = 0 is given by ln(x2 + 11) + csc(y) = C.
Differentiating ln(x2 + 11) + csc(y) = C we get 2x/ x2 + 11 (__) dy/dy=0 or
2x sin2(y) dx + (______)dy = 0.
Find the constant solutions, if any, that were lost in the solution of the differential equation. (Let k represent an arbitrary integer.)
y =_______
Answer:
From the question we are told that
The equation is [tex]2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0[/tex]
Generally the goal of this solution is to prove that the implicit solution of the differential equation above is [tex]ln(x^2 + 11) + csc(y) = C.[/tex]
First Step
Differentiate the solution with respect to x
[tex]0 = \frac{2x}{ x^2 + 11} + [-cot * csc(y) ]\frac{dy}{dx}[/tex]
=> [tex]0 = \frac{2x}{ x^2 + 11} + [-\frac{cos(y)}{ sin(y) }* \frac{1}{sin(y)} ]\frac{dy}{dx}[/tex]
=> [tex]0 = \frac{2x}{ x^2 + 11} + [-\frac{cos(y)}{ sin^2(y) }]\frac{dy}{dx}[/tex]
=>
multiply through by [tex]sin^2(y)[/tex] , [tex] x^2 + 11[/tex], [tex]dx[/tex]
So
=> [tex]2 x (sin^2(y) dx + [-cos(y) (x^2 + 11)]dy = 0[/tex]
Looking at the equation obtained we see that it is equivalent to the differential equation hence the implicit solution of [tex]2x sin^2(y) dx - (x^2 + 11) cos(y) dy = 0[/tex] is [tex]ln(x^2 + 11) + csc(y) = C.[/tex]

2x+2y=42/2
x+y=21 x+y=21
x+2x=21
3x=21/÷3
x=7
7+y=21
y=21-7=14
7×14=98 the area of a rectangle
Answer: 98 ft²
Step-by-step explanation:
Length (L) = 2w
width (w) = w
Perimeter (P) = 2L + 2w
42 = 2(2w) + 2w
42 = 4w + 2w
42 = 6w
7 = w
L = 2w
= 2(7)
= 14
Area = L · w
= 14 · 7
= 98

Step-by-step explanation:
The coordinate which satisfies the inverse of function f(x) is that f⁻(x) are (–3, 2),(6, –1), and (1, 0) so options (A),(B), and (E) will be correct.
What is the inverse of a function?The inverse of a function is basically a reverse function or undo of the function.
For example y = f(x) then inverse will be x = f(y).
It means in the inverse function we need to interchange x and y.
Given points have been labeled in 2 a 2-column table with 6 rows.
The coordinate of any function is given as (x,y) or ( x,f(x) ).
First coordinate of functin f(x) is (0,1) second(2,-3) and so on.
If we do the inverse of the function f(x) is that f⁻(x) then coordinate will interchange is that x will interchange with f(x) then first coordinate (1,0) second (-3,2) and so on.
So if we look at all coordinates which is available among the options are (–3, 2),(6, –1), and (1, 0).
Hence "The coordinate which satisfies the inverse of function f(x) is that f⁻(x) are (–3, 2),(6, –1), and (1, 0)".

One of the assumptions underlying the theory of control charting is that successive plotted points are independent of one another. Each plotted point can signal either that a manufacturing process is operating correctly or that there is some sort of malfunction. Even when a process is running correctly, there is a small probability that a particular point will signal a problem with the process. Suppose that this probability is 0.05. What is the probability that at least one of 10 successive points indicates a problem when in fact the process is operating correctly? What is the probability that at least one of 40 successive points indicates a problem when in fact the process is operating correctly?
Answer:
a) the probability that at least one of 10 successive points indicates a problem when in fact the process is operating correctly is 0.4013
b) the probability that at least one of 40 successive points indicates a problem when in fact the process is operating correctly is 0.8715
Step-by-step explanation:
following how the independence multiplication rule works,
i.e finding p(A)' which is 1 - p(No problem) because what we need is an intersection not a union so;
a) 10 successive points
probability (problem) = 0.05
probability (No problem) = 0.95
required probability = 1 - [probability (No problem)]^10
= 1 - (0.95)^10
= 1 - 0.5987
= 0.4013
the probability that at least one of 10 successive points indicates a problem when in fact the process is operating correctly is 0.4013
b) 40 successive points
probability (problem) = 0.05
probability (No problem) = 0.95
required probability = 1 - [probability (No problem)]^40
= 1 - (0.95)^40
= 1 - 0.1285
= 0.8715
the probability that at least one of 40 successive points indicates a problem when in fact the process is operating correctly is 0.8715
A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a 50-50 chance of getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for 80% of the successful bids and 35% of the unsuccessful bids the agency requested additional information. a. What is the prior probability of the bid being successful (that is, prior to the request for additional information)
Answer:
[tex]Probability = 0.50[/tex]
Step-by-step explanation:
Given
[tex]Probability = 50\ 50\ chance[/tex]
[tex]Successful\ Bids = 80\%[/tex]
[tex]Unsuccessful\ Bids = 35\%[/tex]
Required
Determine the probability before the request of past experience
In this case, we only consider the 50 50 chance probability
[tex]Probability = \frac{50}{50 + 50}[/tex]
[tex]Probability = \frac{50}{100}[/tex]
[tex]Probability = 0.50[/tex]
SOMEONE PLEASE HELP ME WITH THIS QUESTION !!!
Slope can be thought of as the average rate of change in one quantity per unit change in another.
Use the concept of slope to answer the following question: The price of computers has been dropping
for the past ten years. If a desktop PC cost $6000 ten years ago and the same computing power
cost $300 two years ago find the rate of decrease per year. Assume that a linear model applies and
round your answer to the nearest cent.
Answer:
$700
Step-by-step explanation:
Given that:
Cost of desktop PC 10 years ago = $6000
Cost of desktop PC 2 years ago = $300
Linear model applies.
To find the rate of decrease per year, we need to find the slope.
One quantity is cost of PC here and second quantity here is number of years.
[tex]\text{Rate of decrease per year = }\dfrac{\text{Change in Price}}{\text{Change in Number of years}}[/tex]
[tex]\Rightarrow \dfrac{6000-300}{10-2}\\\Rightarrow \dfrac{5700}{8}\approx \bold{\$700}[/tex]
So, the answer is:
There is a decrease of $700 per year.
OR
Rate of decrease per year is $700.
Answer:
700$

If Ari, Ben and Carol each choose a number at random between 1 to 5, inclusive, what is the probability that all pf them choose different number?
Answer:
12/25
Step-by-step explanation:
If one person chooses a number from 1-5 already, they basically have any choice between 1-5 at their disposal. Therefore, there is not much of a probability for them. If the next individual's number will be different, there will be 4 numbers left. Additionally, this means that the next person (let's say Ben) will have a probability 4/5 since that is if he chooses a different number. There will be 3 numbers remaining, so the last person who picks will have a probability of 3/5.
3/5 and 4/5 are boh probabilities, so multiply them together to get one, which is 12/25.

In the diagram below, points A and B are 3 inches apart. Try to find two points that are 1 inch from point A
and 1.5 inches from point B. Why do you think it is impossible to find such points?
A______________________B
3"
Answer:
It is impossible to find two points that are both 1 inch and 1.5 inches from the point A simultaneously as shown in the following proof
From segment addition postulate given a point C that is between the points of a segment AB, we have;
AC + CB = AB
Therefore, where AC = 1 inch and CB = 1.5 inches, we have;
AC + CB = 1 inch + 1.5 inches = 2.5 inches ≠ AB = 3 inches
However it is possible to find two points in which one of the points is 1 inch from the point A while the other point is 1.5 inches from the point B
