Rewriting,

Check to see if this is an exact DE by taking the partial derivative of M with respect to y and N with respect to x.
[tex]M=(-y+x-2)dx[/tex]
=> [tex]M_{y} =-1[/tex]
[tex]N=(y-x)dy[/tex]

Only Euna successfully constructed an equilateral triangle inscribed in a a circle.
What is equilateral triangle?An equilateral triangle's sides are congruent, which indicates that they are all the same length. The inner angles are all equal (60°), as well. Equilateral is a compound word made up of the words "equi," which means equal, and "lateral," which means side. Thus, an equilateral triangle is one that has three sides of equal length. An equilateral triangle in geometry is a triangle whose three sides are equal in length. An equilateral triangle is also equiangular in the conventional Euclidean geometry, meaning that each of the three internal angles is 60 degrees and that all three are congruent with one another.

What is inequality?An inequality in mathematics is a relationship between two expressions or values that is not equal. Thus, imbalance leads to inequality. An inequality creates the link between two values that are not equal in mathematics. Egality is distinct from inequality. When two values are not equal, most commonly use the not equal sign (). Different inequalities are used to contrast values, no matter how little or large. Many simple inequalities may be resolved by modifying the two sides until the variables are all that remain. But a number of things contribute to inequality: Negative values on both sides are divided or added. Trade off the left and right.

Weights of newborn babies were gathered for a study last month at the local hospital. What is the level of measurement of the data?
The level of scale of measurements is the ratio scale for the data of the average weight of newborn babies in ounces.
What is level of Measurement of data?A ratio scale is a numerical scale with a genuine zero and uniform distances between adjacent points. A zero on a ratio scale, in contrast to an interval scale, indicates complete lack of the variable being measured. Examples of ratio scales include length, area, and population.
As, There are four scales of measurement: Nominal, Ordinal, Interval, and Ratio.
First, The categories in this scale are given names, hence the label "nominal." There is no innate hierarchy among the categories. Simply said, it is impossible to say that one category is superior to or better than another.
Ordinal scale: It is possible to rationally organise the various categories in a meaningful order. The distinction between the categories is not "meaningful," nevertheless.
Interval scale: Doubling has no significance, but values (not categories) can be arranged and have substantial differences. The lack of a "absolute zero" is the reason of this.
Scale of ratios: The values can be arranged in a way that makes a meaningful difference, and doubling also makes a difference. "Absolute zero" exists.
As a result, the ratio scale for the level of measurements is used to determine the average weight of newborn babies.

Add write each sum in simplest form 5/12+1/4
Before solving for fractions, you must know what you're doing. This will list information you should know to solve fraction problems.
A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters
Step by Step Answer Explanation[tex]\frac{5}{12} + \frac{1}{4}[/tex] is our equation, so let's solve this step by step,
Common Denominator
As you can see, the fractions have unlike denominators. An unlike denominator is when 2 or more fractions have different denominators. One of our denominators is 12 and the other is 4, so this shows we have unlike denominators. The way we get the denominators to be the same is multiplying. Its a quicker method to easily make them the same. We can also skip count until the numbers meet:
12: 12,
4: 4, 8, 12
The fraction denominator can be 12. We can also prove that it is 12 by showing the Least Common Denominator, or LCD. LCD (5/12, 1/4) = 12.
[tex]\frac{5}{12}[/tex] × [tex]\frac{1}{1}[/tex] = [tex]\frac{5}{12}[/tex] . We multiply this by [tex]\frac{1}{1}[/tex] because the denominator is already 12.
[tex]\frac{1}{4}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{3}{12}[/tex]. We multiply this by [tex]\frac{3}{3}[/tex] so we can make the denominator 12.
Adding the fractions
Now that we have our equation, [tex]\frac{5}{12}[/tex] + [tex]\frac{3}{12}[/tex], we can easily add the fractions.
We do not add the denominators, however, we do add the numerators. We can express this as [tex]\frac{5+3}{12}[/tex]. 5 + 3 = 8. So, the numerator is 8. This means our answer is [tex]\frac{8}{12}[/tex].
Reduce
As your question says the sum must be in simplest form, you must reduce the answer to get it in simplest form. To reduce, you must divide. [tex]\frac{8}{12}[/tex] can be reduced, or divided by 4 to get it to simplest form. [tex]\frac{8}{12}[/tex] ÷ [tex]\frac{4}{4}[/tex] = [tex]\frac{2}{3}[/tex].

Prove that cosec (A+B) = sinA cosB - cosA sinB ÷ ( sinA + sinB ) ( sinA - sinB )
The formula cosec (A + B) = sinA cosB - cosA sinB ÷ (sinA + sinB)(sinA - sinB) can be proven using the trigonometric identities.
How to prove this?Starting with the definition of cosecant:
cosec (A + B) = 1/sin (A + B)
Using the sum-to-product identity:
sin (A + B) = sinA cosB + cosA sinB
Substituting this expression into the definition of cosecant:
cosec (A + B) = 1 / (sinA cosB + cosA sinB)
Using the difference-to-product identity:
sinA - sinB = 2sin((A - B)/2)cos((A + B)/2)
Dividing both numerator and denominator by 2sin((A - B)/2)cos((A + B)/2), we get:
cosec (A + B) = (sinA cosB - cosA sinB) ÷ (sinA + sinB)(sinA - sinB)
Therefore, the formula cosec (A + B) = sinA cosB - cosA sinB ÷ (sinA + sinB)(sinA - sinB) has been proven.

[tex] 1. \begin{cases} y = -\dfrac{1}{2}x+2\\\\ y = -3x - 3 \end{cases}[/tex]
Firstly let's make a table;
[tex]\boxed{\begin{array}{c|c|c} x & 0 & 1 \\ y & 2 & 1.5 \end{array}}[/tex]
Now plot the points , (0,2) and (1,1.5) .
Similarly make another table for second equation [tex] y = -3x - 3[/tex] as ,
[tex]\boxed{\begin{array}{c|c|c} x & 0 & 1 \\ y & -3 & -6\end{array}}[/tex]
Now draw the lines joining the points. Hence from the graph the line intersects at (-2,3)
So the solution to equations are ,
[tex]x = - 2[/tex][tex]y = 3[/tex]_________________________________
Similarly we will solve the second set of equations as ,
[tex] 2. \begin{cases} x-4y=12\\\\ 7x-4y=12 \end{cases}[/tex]
make a table for plotting equation [tex] x-4y=-12[/tex]
[tex]\boxed{\begin{array}{c|c|c} x & 12 & 16 \\ y & 0 & 1\end{array}}[/tex]
make a table for plotting equation [tex] 7x-4y=12[/tex]
[tex]\boxed{\begin{array}{c|c|c} x & 0 & 2 \\ y & -3 & 0.5\end{array}}[/tex]
Now we see that the equations intersect at point (4,4) So the solution to the given equation is ,
[tex]x = 4[/tex][tex]y = 4[/tex]________________________________
[tex] 3. \begin{cases} -8x-4y = 12 \dots (1)\\\\ x=y\dots(2)\end{cases}[/tex]
substitute value of equation 2 in 1
[tex]\longrightarrow -8x - 4x = 12 \\ [/tex]
simplify,
[tex]\longrightarrow -12x = 12[/tex]
Divide both sides by 12 ,
[tex]\longrightarrow\underline{\underline{ x = -1}} [/tex]
Substitute this value in equation 2 as ,
[tex]\longrightarrow x = y \\ [/tex]
[tex]\longrightarrow\underline{\underline{ y = -1}} [/tex]
Hence our required solution is ,
[tex]x = - 1[/tex][tex]y = - 1[/tex]___________________________________
[tex] 4. \begin{cases} 2x + 4y = -10 \dots (1)\\\\ -7x -y = 22(2)\end{cases}[/tex]
Taking equation 2 ,
[tex]\longrightarrow y = -7x -22 [/tex]
substitute this value in equation 1,
[tex]\longrightarrow 2x + 4(-7x-22)=-10\\[/tex]
[tex]\longrightarrow 2x -28x -88 = -10\\ [/tex]
[tex]\longrightarrow -26x = 78\\[/tex]
divide both sides by 26,
[tex]\longrightarrow\underline{\underline{ x = -3}} [/tex]
Again, substitute this value in equation 2 , as ;
[tex]\longrightarrow y = -7(-3) -22\\ [/tex]
[tex]\longrightarrow y = 21 -22\\ [/tex]
[tex]\longrightarrow\underline{\underline{ y = -1}} [/tex]
hence our required solution is ,
[tex]x = - 3[/tex][tex]y = - 1[/tex]And we are done!

Given that, the average high temperatures in degrees for a city are 58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57.
Now, average = (58+61+71+77+91+100+105+102+95+82+66+57)/12
= 965/12
= 80.42
If a value of 101° is added to the data, then the new average is
(965+101)/(12+1)
= 1066/13
= 82
Therefore, for the given scenario the mean changes from 80.42 to 82.

Enlarge shape A by scale factor 2 with centre of enlargement (1, 5)
The coordinates of the vertices of the image include the following: (-1, 3), (-1, -1), (5, -1), and (7, 3).
How to enlarge shape A by a scale factor of 2?In this exercise, we would have to dilate (enlarge) the coordinates of the pre-image by using a scale factor of 2 centered at the point (1, 5) by using this mathematical expression:
(x, y) → (k(x - a) + a, k(y - b) + b)
For coordinate 1, we have;
Coordinate 1 = (2, 4) → (2(2 - 1) + 1, 2(4 - 5) + 5)
Coordinate 1 = (2, 4) → (2(-1) + 1, 2(-1) + 5)
Coordinate 1' = (-1, 3).
For coordinate 2, we have;
Coordinate 2 = (2, 2) → (2(2 - 1) + 1, 2(2 - 5) + 5)
Coordinate 2 = (2, 2) → (2(-1) + 1, 2(-3) + 5)
Coordinate 2' = (-1, -1).
For coordinate 3, we have;
Coordinate 3 = (3, 2) → (2(3 - 1) + 1, 2(2 - 5) + 5)
Coordinate 3 = (3, 2) → (2(2) + 1, 2(-3) + 5)
Coordinate 3' = (5, -1).
For coordinate 4, we have;
Coordinate 1 = (4, 4) → (2(4 - 1) + 1, 2(4 - 5) + 5)
Coordinate 1 = (4, 4) → (2(3) + 1, 2(-1) + 5)
Coordinate 1' = (7, 3).

A function f(x) is said to have a jump……
A function f(x) is said to have a jump discontinuity at x = a if:
3. The left and right limits are not equal.
The function has a jump discontinuity at x = 6 because:
lim x -> 6^- f(x) = 17.lim x -> 6^+ f(x) = 2/13.The different lateral limits are the reason given for the jump discontinuity, as shown in the graph presented at the end of the answer.
What is the continuity concept?A function f(x) is continuous at x = a if it is defined at x = a, and the lateral limits are equal, that is:
[tex]\lim_{x \rightarrow a^-} f(x) = \lim_{x \rightarrow a^+} f(x) = f(a)[/tex]
If the lateral limits are different, the limit does not exist and the function is not continuous at x = a, being said to have a jump discontinuity.
The function has a jump discontinuity at x = 6 because:
lim x -> 6^- f(x)= 4(6) - 7 = 17. (left of 6 is less than 6).lim x -> 6^+ f(x) = 2/(6 + 7) = 2/13. (right of 6 is more than 6).More can be learned about the continuity of a function at https://brainly.com/question/24637240

please i really need help
here is the picture
step by step
Hector manages Food Plaza, a small grocery store. Based on the previous year's sales data, he estimates that Food Plaza can sell
a = -2000p + 7540 lemons this year, where p is the price of a single lemon and a is the total amount of lemons sold at price p.
Walt supplies Food Plaza with all the fruits and vegetables they sell. Walt can sell Hector at most 5000 lemons in a single year.
If Food Plaza pays Walt $1.60 per lemon on average, how many lemons should Hector buy from Walt in order to maximize the
store's profit?
To maximize the store's profit, Hector should aim to sell as many lemons as possible while paying the lowest price possible for them. Since Hector estimates that he can sell a maximum of -2000p + 7540 lemons at price p, and Walt can supply at most 5000 lemons, Hector should buy all of the 5000 lemons from Walt.
To determine the price at which Hector should buy the lemons from Walt, we need to consider the average cost of the lemons. If Hector buys 5000 lemons at $1.60 per lemon, he will spend a total of 5000 x $1.60 = $8000 on lemons.
If he sells all 5000 lemons at the price p, his revenue will be (-2000p + 7540) x 5000 = -10,000,000p + 37,700,000.
His profit will be the difference between revenue and cost, which is given by:
Profit = -10,000,000p + 37,700,000 - $8000
To maximize profit, we need to take the derivative of the profit function with respect to p and set it equal to zero:
dProfit/dp = -10,000,000 = 0
Solving for p, we get:
p = $1.00
Therefore, Hector should buy 5000 lemons from Walt at $1.00 per lemon to maximize the store's profit.
A coin that lands on heads with probability p is continually flipped. Compute the expected number of flips X that are made until a string of r heads in a row is obtained. (string of r heads means a successive sequence of r heads. For example, if r = 2 and you flipped the coins such that you obtained HTHTHHTTHHH, then X=6) Hint: Condition on the time of the first occurrence of tails to obtain the equation E[X] = (1-p) ∑ Pi-1(I + E[X]) + (1-P) ∑ Pi-1r
The expected number of flips to get a string of r heads in a row, given that the probability of getting heads in each flip is p.
What do you mean by probability?Probability is a scale between 0 and 1 that represents the possibility of an event happening. An event with probability 1 is guaranteed to happen, while an event with probability 0 is impossible. The number of favorable outcomes divided by the total number of potential outcomes in the sample space yields the probability of an event A, commonly denoted as P(A). The sample space, for a fair six-sided die, is the set of all potential outcomes, such as 1, 2, 3, 4, 5, and 6. The probability of rolling a 4 is 1/6. Numerous disciplines employ probability to make predictions, deduce conclusions, and make judgments in the face of uncertainty.
We can use a recursive formula to find the expected number of flips X.
Let X_i be the expected number of flips to get a string of r heads in a row, starting from the i-th flip. Then, X_i can be expressed in terms of X_{i+1}:
X_i = (1 - p) + p(1 + X_{i+1})
Here, (1 - p) represents the case where the i-th flip results in tails, and p(1 + X_{i+1}) represents the case where the i-th flip results in heads and we have to continue flipping until we get a string of r heads in a row.
To find the expected number of flips X, we need to sum over all X_i, starting from the first flip:
E[X] = X_1 = (1 - p) + p(1 + E[X])
Solving for E[X], we get:
E[X] = 1/(1 - p)
This formula gives us the expected number of flips to get a string of r heads in a row, given that the probability of getting heads in each flip is p.
