√(1- x²) y' = xy
Calculus, please help
Answers
In the given differential equation, the general solution to the differential equation is: y = Ae^(√(1 - x²)), where A is any non-zero constant.
How to solve Differential Equation?To solve this differential equation, we can start by using separation of variables.
√(1 - x²) y' = xy
We can rewrite this equation as:
y' / y = x / √(1 - x²)
Now we can integrate both sides:
∫ (y' / y) dy = ∫ (x / √(1 - x²)) dx
ln|y| = -√(1 - x²) + C
where C is the constant of integration.
Taking the exponential of both sides:
|y| = e^(-√(1 - x²) + C) = e^C / e^(√(1 - x²))
Since we only care about the magnitude of y, we can drop the absolute value signs and write:
y = Ae^(√(1 - x²))
where A = ± e^C is another constant of integration.
Therefore, the general solution to the differential equation is:
y = Ae^(√(1 - x²))
where A is any non-zero constant.
Note that the solution only holds for |x| ≤ 1, since otherwise the expression inside the square root would become negative, and the solution would not be real-valued.

A store pays $2.50 per pound for cat liter. One cubic foot of cat liter weighs about 48 pounds. What is the selling price of cat liter in the container shown when the markup is 20%?
Answers
Answer: The selling price of cat litter in the container shown when the markup is 20% is $3.00 per pound.
Step-by-step explanation:
One cubic foot of cat litter weighs about 48 pounds, so the weight of one pound of cat litter is 1/48 cubic feet.
The store pays $2.50 per pound for cat litter, so the cost of one pound of cat litter is $2.50.
To find the selling price with a 20% markup, we add 20% of the cost to the cost.
20% of $2.50 is $0.50.
So, the selling price per pound is $2.50 + $0.50 = $3.00.

ABCD is a trapezium. P is a point along AC such that AP=4PC. DC=1/4AB.
a) express PB in terms of a and b in its simplest form
b) express DP in terms of a and b in its simplest form
c) does DPB form a straight line?
Answers
Answer:
a) We can use similar triangles to find PB in terms of a and b. Let x be the length of AD. Then, using the fact that AP = 4PC, we have:
PC = CP = x - b
AP = 4(x - b)
Also, using the fact that DC = (1/4)AB, we have:
AD = x
AB = 4DC = x/4
BC = AB - AD = x/4 - x = -3x/4
Now, consider the similar triangles PBC and ABD:
PB/AB = BC/AD
PB/(x/4) = (-3x/4)/x
PB = -3/4(x/4) = -3x/16
Finally, substituting x = a + b, we have:
PB = -3(a + b)/16
b) Using the same similar triangles as in part (a), we have:
DP/DC = PB/BC
DP/(1/4)AB = PB/(-3x/4)
DP = -3/4(PB)(DC/BC)AB
DP = -3/4(PB)(1/4)/(AB - AD)AB
Substituting the expressions for PB, AB, and AD from part (a), we get:
DP = -3(a + b)/16 * 1/4 / (-3(a + b)/4) * (a + b)/4
DP = -3/16 * 1/4 * 4/(3(a + b)) * (a + b)
DP = -3/16
So, DP = -3/16(a + b)
c) To check if DPB forms a straight line, we need to verify if the slopes of DP and PB are equal. Using the expressions we found in parts (a) and (b), we have:
Slope of PB = Δy/Δx = (-3/16(a+b) - 0)/(0 - (-3(a+b)/16)) = 3/16
Slope of DP = Δy/Δx = (-3(a+b)/16 - (-3/16(a+b)))/(1/4 - 0) = -3(a+b)/4
Since the slopes are not equal, DPB does not form a straight line.
solve for x; (a+bx)/(a+b)=(c+dx)/(c+d) if cb=ad
Answers
Answer:
To solve for x, we can start by cross-multiplying the equation to eliminate the denominators:
(a+bx)(c+d) = (c+dx)(a+b)
Expanding the terms on both sides:
ac + adx + bc + bdx^2 = ac + abx + cdx + bd
Simplifying and rearranging the terms:
adx + bdx^2 - abx - cdx = bd - ac
dx(ad - ab - c) = bd - ac
Now, since we know that cb=ad, we can substitute ad=cb into the equation:
dx(cb - ab - c) = bd - ac
dx(cb - ab - c) = b(cd - ac)
x = b(cd - ac)/(d(cb - ab - c))
Therefore, the solution for x is:
x = b(cd - ac)/(d(cb - ab - c))

58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 82° is changed to 94°, which of the following measures changes the most and what is the new value?
IQR 34°
Range 48°
Mean 81.4°
Median 84°
Answers
Answer:
If we change the value of 82° to 94°, the new data set becomes:
58, 61, 71, 77, 91, 100, 105, 102, 95, 94, 66, 57
IQR:
To find the new interquartile range (IQR), we first need to find the new values of the first quartile (Q1) and the third quartile (Q3). The median of the original data set is 84°, which is between the 6th and 7th values when the data is ordered. So, the first half of the data set consists of the values 58, 61, 71, 77, 82, and 91, and the second half consists of the values 94, 95, 100, 102, 105.
The new Q1 is the median of the first half of the data set, which is (71 + 77) / 2 = 74. The new Q3 is the median of the second half of the data set, which is (100 + 102) / 2 = 101.
The new IQR is Q3 - Q1 = 101 - 74 = 27.
Range:
The range is simply the difference between the largest and smallest values in the data set. Before the change, the range was 105 - 57 = 48. After the change, the range is 105 - 58 = 47.
Mean:
To find the new mean, we add up all the temperatures and divide by the number of temperatures. Before the change, the sum was 980 and there were 12 temperatures, so the mean was 980/12 = 81.7° (rounded to one decimal place). After the change, the sum is 982 and there are still 12 temperatures, so the new mean is 982/12 = 81.8° (rounded to one decimal place).
Median:
The median is the middle value in the data set when it is ordered. Before the change, the median was 84°. After the change, the median is still 84°, since only one value was changed and it did not affect the position of the median.
Therefore, the IQR changes the most, increasing from 34° to 27°. The new value of the IQR is 27.

Med Nail % Abund.

Answers
According to the question the percent abundance of the medium nails in the sample is approximately 18.95%.
Explain medium?Whenever the set of data is presented from least to largest, the median is indeed the number in the middle. For instance, since 8 is in the middle, this would represent the median value here.
To find the percent abundance of the medium nails in the sample, we first need to calculate the total number of nails in the sample:
Total number of nails = 67 + 18 + 10 = 95
Next, we can calculate the percent abundance of the medium nails using the formula:
Percent abundance = (number of medium nails / total number of nails) x 100%
Using the values from of the table as inputs, we obtain:
Percent abundance of medium nails = (18 / 95) x 100% ≈ 18.95%
As a result, the sample's average percentage of medium nails is roughly 18.95%.

A dilation centered at the origin maps the point (4,6) to the point (5/2,15/4). What is the scale factor of the dilation
Answers
We may be confident that this is the correct scale factor because both equation equations yield the same value of k. As a result, the dilatation has a scale factor of 5/8 and is centered at the origin.
What is equation?An equation is a statement in mathematics that states the equality of two expressions. An equation has two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the value "9". The purpose of equation solving is to determine which variable(s) must be changed in order for the equation to be true. Simple or complex equations, regular or nonlinear equations, and equations with one or more elements are all possible. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are employed in a variety of mathematical disciplines, including algebra, calculus, and geometry.
Let (x,y) be a point on the plane and k be the dilation scale factor centred at the origin. The image of (x,y) under dilation is thus given by (kx, ky).
The dilation is given as (4,6) to (5/2,15/4). That is to say:
[tex]k(4) = 5/2 \sk(6) = 15/4\\k = 5/8 \sk = 5/8[/tex]
We may be confident that this is the correct scale factor because both equations yield the same value of k. As a result, the dilatation has a scale factor of 5/8 and is centered at the origin.

Write your answer as a fraction or whole number.
P(on time)=
Answers
The experimental probability that the next train to arrive at Danville Station will be on time is 3/4 or 0.75.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
The experimental probability of the next train to arrive at Danville Station being on time is given by the number of on-time trains divided by the total number of trains that arrived -
experimental probability = number of on-time trains / total number of trains
From the information given, we know that out of the last 20 trains to arrive, 15 were on time. Therefore -
number of on-time trains = 15
total number of trains = 20
Substituting these values into the equation, we get -
experimental probability = 15 / 20
Simplifying the fraction, we get -
experimental probability = 3/4
Therefore, the experimental probability value is obtained to be 3/4 or 0.75.

After cutting the squares, the length of each shorter side (and the side length of each triangular quilt piece) is approximately 14√2 inches i.e. B.
What are squares?
A square is a two-dimensional shape with four straight sides that are of equal length and four right angles (90-degree angles) at the corners. It is a special case of a rectangle, where all four sides are the same length. A square can also be thought of as a special type of rhombus, where the angles are all right angles.
Now,
Since the hypotenuse of each triangle is 28 inches long, we know that this is also the longest side of the right triangle formed by the two shorter sides of the triangle. Let's call one of the shorter sides x.
Using the Pythagorean Theorem, we can find the length of the other shorter side:
c²= a² + b²
28² = x² + x²
784 = 2x²
x² = 392
x = √(392)
x=14√2 in
Therefore, the length of each shorter side (and the side length of each triangular quilt piece) is approximately 14√2 inches (rounded to two decimal places).

A health club surveyed its members to determine if they worked out alone or with a personal trainer. The survey shows that 111 members work out alone, 67 work out with a personal trainer, and 41 sometimes work out alone and sometimes work out with a personal trainer.
Answers
The probability that a randomly selected member always works out alone or always works out with a personal trainer is 0.5393.
What is probability?
The idea of probability can be used to determine if an event is possible. It is solely useful for calculating the likelihood that an event will occur. a scale from 0 to 1, where 0 represents impossibility and 1 represents a specific occurrence.
We are given that 111 members work out alone, 67 work out with a personal trainer, and 41 sometimes work out alone and sometimes work out with a personal trainer.
So, the number of members who always work out alone is 111 - 41 = 70.
Similarly, the number of members who always work out with a personal trainer is 67 - 41 = 26.
Therefore, 96 members are there who either exercise alone or always exercise with a personal trainer.
Number of people surveyed = 111 + 67 - 41 = 137
Let A be the event where a member always exercises alone and B be the event where a member always exercises with a personal trainer.
From this, we get
P (A) = [tex]\frac{70}{137}[/tex]
P (B) = [tex]\frac{26}{137}[/tex]
P (A and B) = [tex]\frac{26}{137}[/tex]
So,
⇒ P(A or B) = P(A) + P(B) - P(A and B)
⇒ P(A or B) = [tex]\frac{70}{137}[/tex]+ [tex]\frac{26}{137}[/tex]- [tex]\frac{26}{137}[/tex]
⇒ P(A or B) = [tex]\frac{70}{137}[/tex]
Hence, the probability that a randomly selected member always works out alone or always works out with a personal trainer is 0.5393.

Mean:The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values. The formula for the mean of a population is
[tex]\mu = \frac{{\sum}x}{N}[/tex]
The formula for the mean of a sample is

[tex]\frac{3432}{8} = 429[/tex]
Median:The median of a data set is found by putting the data set in ascending numerical order and identifying the middle number. If there are an odd number of data values in the data set, the median is a single number. If there are an even number of data values in the data set, the median is the average of the two middle numbers. Sorting the data set for the values entered above we have:
[tex]134, 185, 193, 217, 471, 580, 799, 853[/tex]
Since there is an even number of data values in this data set, there are two middle numbers. With 8 data values, the middle numbers are the data values at positions 4 and 5. These are 217 and 471. The median is the average of these numbers. We have

Without a graph provided, it's difficult to determine which of the given functions represents the graph on the right. However, we can analyze each function to see if it has any characteristics that match the shape of the graph.
f(x) = x(x – a)(x – b)2
This function has one x-intercept at x = 0 and a double root at x = b. If b > a, then the function will have a local maximum at x = a and a local minimum at x = b. This function may represent a graph with a single x-intercept, a double root, and a local maximum and minimum.
f(x) = (x – a)(x – b)2
This function has one x-intercept at x = a and a triple root at x = b. If b > a, then the function will have a local minimum at x = a and a local maximum at x = b. This function may represent a graph with a single x-intercept, a triple root, and a local minimum and maximum.
f(x) = x(x – a)³(x – b)
This function has one x-intercept at x = 0 and a triple root at x = a. If a < b, then the function will have a local minimum at x = b. This function may represent a graph with a single x-intercept, a triple root, and a local minimum.
f(x) = x²(x – a)²(x – b)²
This function has two x-intercepts at x = 0 and x = a and a double root at x = b. If b > a, then the function will have a local maximum at x = a and a local minimum at x = b. This function may represent a graph with two x-intercepts, a double root, and a local minimum and maximum.

Jochebed wants to buy a piece of land, and the owner will sell it to her for R20 000 cash. Alternatively, he will let her pay for it with five annual installments of R5 000 each, the first one being due right now. What is the implied interest rate here?
Answers
Answer:25% interest or $5,000
5\100= .05
.05 / 20= .0025
5,000/1,000=0.5
0.5 / 20=.25
Step-by-step explanation:
Answer:
Step-by-step explanation:
To determine the implied interest rate in this scenario, we can use the concept of present value (PV) and future value (FV).
If Jochebed decides to pay the full amount of R20 000 cash right now, then the PV is R20 000 and the FV is also R20 000. Therefore, the implied interest rate on this option is 0%.
If Jochebed decides to pay in five annual installments of R5 000 each, then the PV of the land is equal to the sum of the present values of each installment. Using the formula for present value of an annuity, we can calculate the PV as:
PV = R5 000 x ((1 - (1 + r)^-5) / r)
where r is the implied interest rate. Solving for r, we get:
r = 7.18%
Therefore, the implied interest rate on the installment plan is 7.18%.
A charity organization has to sell a few tickets to their fundraiser just to cover necessary production costs. After selling 10 tickets they were still at a net loss of $800 (due to the production costs). They sold each tickets for $70.
Answers
the organization needs to sell at least 22 tickets to break even.
What is the arithmetic operation?
The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.
Let C be the total production cost and n be the number of tickets sold.
From the problem, we know that the organization had a net loss of $800 after selling 10 tickets, so we have:
10(70) - C = -800
Simplifying, we get:
C = 1500
This means that the total production cost was $1500.
The revenue from selling n tickets at $70 per ticket is given by:
R = 70n
Substituting the values of R and C, we get:
70n = 1500
Solving for n, we get:
n = 1500/70 = 21.43
Since we can't sell a fraction of a ticket, we need to round up to the nearest whole number.
Therefore, the organization needs to sell at least 22 tickets to break even.

Applying the angle addition postulate, the value of x in the image given is calculated as: 49.
What is the Angle Addition Postulate?The Angle Addition Postulate states that for any angle, the sum of its adjacent angles is equal to the angle formed by combining them.
Therefore, we have:
x + 11 + x + 23 = 132
Combine like terms to find the value of x:
2x + 34 = 132
2x = 132 - 34
2x = 98
2x/2 = 98/2

Find the Perimeter of the given figure. Remember that this is a composite figure. Be sure to show your work or explain how you found your answer in question
Answers
Answer:
Start off with the 20ft sides
20x2 =40ft
40ft + 8ft = 48ft
Now we need to find the perimeter of the half circle.
Since we know the diameter of the half circle is 8ft, we can use the following formula: Diameter x Pi = Circumference
Plug in:
8ft x 3.14159 = 25.132ft
25.132 /2 gives us the perimeter of the half circle
25.132 / 2 = 12.566
Rounded = 12.57 ft
48 ft + 12.57 ft = 60.57 feet perimeter.
The perimeter of the given solution is 76.56 feet.
We need to find the perimeter of the figure by splitting the figure into a rectangle and a semi-circle. The radius for the semi-circle is found by dividing the diameter by 2, Radius = 8 ÷ 2 = 4.
Therefore, the formula for finding the Perimeter of the given rectangle is
P = 2( l+b )
P = 2( 20 + 8)
P = 56 feet.
now, the formula for the circumference of a semi-circle is
C = [tex]\pi[/tex]r + 2r
C = 3.14( 4) + 2 (4)
C = 20.56 feet.
Therefore, the perimeter of the given figure is
The perimeter of the rectangle + circumference of the Semi-circle
= 56 + 20.56
= 76.56 feet
Therefore, the perimeter of the given solution is 76.56 feet.
