how to solve this separable differential equation?
The solution to the differential equation \(2^{\sqrt{x}}\frac{dy}{dx} = cosce(ln(y))\) is,
\(\frac{y sin(ln(y))}{2} - \frac{y cos(ln(y))}{2} = C - \frac{2 ln(2) \sqrt{x} + 2}{ln^2(2)2^{\sqrt{x}}}\).
What is a differential equation?Any equation with at least one ordinary or partial derivative of an unknown function is referred to as a differential equation.
The given differential equation is \(2^{\sqrt{x}}\frac{dy}{dx} = cosce(ln(y))\).
Now, multiplying both sides by dx we,
\(2^{\sqrt{x}}dy = cosce(ln(y))dx\).
Dividing both sides by \(2^{\sqrt{x}}\) we have,
\(sin(ln(y))dy = \frac{dx}{2^{\sqrt{x}}}\).
\(\[ \int sin(ln(y))dy = \int \frac{dx}{2^{\sqrt{x}}}\).
\(\frac{y sin(ln(y))}{2} - \frac{y cos(ln(y))}{2} = C - \frac{2 ln(2) \sqrt{x} + 2}{ln^2(2)2^{\sqrt{x}}}\).

The heat, (H), required to melt copper is proportional to the copper's mass in grams (g). Suppose the number of calories to melt 1 gram of copper is represented by c Which statements are true for this situation? A) g = Hc B) H = cg H=9. с D) The mass of the substance is the constant of proportionality. E) The number of calories to melt one gram is the constant of proportionality.
The exercise tells you that the heat (H) needed to melt copper is proportional to its mass (g).
"c" represents the number of calories needed to melt 1 gram of copper.
To determine how many calories, c, needed to melt "g" grams of copper, you have to multiply the calories per gram by the number of grams: "cg"
So the heat needed is equal to the number of calories needed to melt one gram (which is the coefficient of variation of the relationship) multiplied by the mass of copper you want to melt.
You can express this as follows:
\(H=cg\)So the true statements are
B) H=cg
E) The number of calories to melt one gram is the constant of proportionality

The distance from the center of the Earth to the point where the net gravitational force is zero is one-ninth the distance from the Earth to the Moon.
Let's assume that the distance from the center of the Earth to this point is denoted as x.
Given:
Mass of the Moon (M\(_{moon}\)) = 1/81 × M\(_{earth}\)
Distance from Earth to Moon (d\(_{moon}\)) = distance on center
According to the principle of gravitational equilibrium, the gravitational force from the Earth and the gravitational force from the Moon acting on an object at that point must balance out. Mathematically, we can express this as:
F\(_{earth}\) = F\(_{moon}\)
The gravitational force between two objects can be calculated using Newton's law of universal gravitation:
F \(_{gravity}\)= G × (m₁ × m₂) / r²
Where:
G is the gravitational constant (approximately 6.67430 x 10⁻¹¹m²/kg/s²)
m₁ and m₂ are the masses of the two objects
r is the distance between the centers of the two objects
Considering the gravitational forces involved:
F\(_{gravity}\)\(_{earth}\) = G ₓ (M\(_{EARTH}\) ₓ m\(_{OBJECT}\)) / (d\(_{earth}\))²
F\(_{gravity}\) \(_{moon}\) = G ₓ (M \(_{moon}\) ₓ m\(_{object}\)) / (d \(_{moon}\))²
Since we are looking for the point where the net gravitational force is zero, we set these two forces equal to each other:
G × (M\(_{earth}\) × m\(_{object}\)) / (d\(_{earth}\))² = G × (M \(_{moon}\) × m\(_{object}\)) / (d \(_{moon}\))²
Canceling out the common factors of G and m\(_object}\), and substituting the given values:
(M\(_{earth}\) × 1) / (d\(_{earth}\))² = (M \(_{moon}\) × 1) / (d \(_{moon}\))²
Rearranging the equation:
(d\(_{earth}\))²/ (M\(_{earth}\)) = (d \(_{moon}\))² / (M \(_{moon}\))
Taking the square root of both sides:
d\(_{earth}\) / √(M \(_{moon}\))) = d_moon / √(M \(_{moon}\))
Substituting the given values:
d\(_{earth}\) /√(M\(_{earth}\)) = d\(_{moon}\) / √(1/81 × M\(_{earth}\))
Simplifying further:
d\(_{earth}\) / √(M\(_{earth}\)) =d\(_{moon}\) / (1/9 × √(M\(_{earth}\)))
Multiplying both sides by √(M\(_{earth}\)):
d\(_{earth}\) = (1/9) × d\(_{moon}\)

Answer:
If B is between A and C, AB = x, BC = 2x + 2, and AC = 14, find the value of x. Then find AB and BC.
Step-by-step explanation:
AB=x
BC = 2x + 2BC=2x+2
AC =14AC=14
Required
Determine x, AB and BC.
Since B is between A and C;
AB + BC = ACAB+BC=AC
Substitute x for AB; 2x + 2 for BC and 14 for AC
x + 2x + 2 = 14x+2x+2=14
3x + 2 = 143x+2=14

3. By using the properties of determinant, evaluate the following if
a. We have \(\det(A^\top) = \det(A)\) for any square matrix A, so the determinant is the same, 10.
b. If a row or column is multiplied by some number, then the determinant of that matrix is equal to that number times the determinant of the original matrix. In this case, the second row is multiplied by 3 and the third row by 2, so the determinant is 2•3•10 = 60.
c. The same property in (b) is involved here (first row multiplied by -1, second by 3) but the second and third columns have been swapped relative to the original matrix. When rows or columns get permuted like this, the value of the determinant changes by a power of (-1). The power depends on how many tranpositions are needed to recover the original matrix.
\(\begin{vmatrix}-a&-c&-b\\3d&3f&3e\\g&i&h\end{vmatrix} = -3\begin{vmatrix}a&c&b\\d&f&e\\g&i&h\end{vmatrix} = 3\begin{vmatrix}a&b&c\\d&e&f\\g&h&i\end{vmatrix}\)
and we end up with a determinant of 3•10 = 30.
The defect length of a corrosion defect in a pressurized steel pipe is normally distributed with mean value 28 mm and standard deviation 7.6 mm.(a)What is the probability that defect length is at most 20 mm
Answer:
14.69% probability that defect length is at most 20 mm
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
\(\mu = 28, \sigma = 7.6\)
What is the probability that defect length is at most 20 mm
This is the pvalue of Z when X = 20. So
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{20 - 28}{7.6}\)
\(Z = -1.05\)
\(Z = -1.05\) has a pvalue of 0.1469
14.69% probability that defect length is at most 20 mm

The side of a triangle are in the ratio 4:4:3 what kind of triangle is it (b) calculate the smallest angle of the triangle to the nearest degree
The smallest angle of the equilateral triangle is 60 degrees
If the sides of a triangle are in the ratio 4:4:3, it implies that the lengths of the sides are proportional.
To determine the type of triangle, we examine the side lengths. Since all three sides are equal in length, we have an equilateral triangle.
For an equilateral triangle, all angles are equal. To calculate the smallest angle, we divide the total sum of angles in a triangle (180 degrees) by the number of angles, which is 3:
Smallest angle \(= \frac{180}{3} = 60\)\) degrees.
Therefore, the smallest angle of the equilateral triangle is 60 degrees (to the nearest degree).

In a sample of 560 adults, 336 had children. Construct a 95% confidence interval for the true population proportion of adults with children.
Give your answers as decimals, to three places
< p <
What is the expected value of �?
The confidence interval is 0.559 < p < 0.641 and expected value is 0.600
Confidence IntervalTo construct a confidence interval for the true population proportion, we can use the formula:
p ± Z * √((p × (1 - p)) / n)
Where:
p = sample proportion (336/560)
Z = critical value for the desired confidence level
95% confidence = Z-value of approximately 1.96
n = 560
Let's calculate the confidence interval:
p = 336/560 ≈ 0.600
Z ≈ 1.96 (for a 95% confidence level)
n = 560
Plugging these values into the formula:
p ± Z × √((p × (1 - p)) / n)
0.600 ± 1.96 × √((0.600 × (1 - 0.600)) / 560)
0.600 ± 1.96 × √((0.240) / 560)
0.600 ± 1.96 × √(0.0004285714)
0.600 ± 1.96 × 0.020709611
0.600 ± 0.040564459
The confidence interval is:
0.559 < p < 0.641
Therefore, the 95% confidence interval for the true population proportion of adults with children is 0.559 < p < 0.641.
The expected valueFor proportions, the expected value is simply the sample proportion, which is approximately 0.600.
