The radius of Deimos to one significant digit in meters is approximately 9.4 m

.

Given the ratio of the Sun-from-Mars distance to Deimos-from-Mars distance is 365,000, the distance between Mars and Deimos can be found to bedeimos distance = Sun-Mars distance / 365,000

Next, we can find the diameter of Deimos by noting that 550 of its diameters is equal to the distance it takes to transit the shadow of Mars during a lunar eclipse.

Let's call the diameter of Deimos "d", so we can

diameter = 1/550 * deimos distance

Finally, the Sun appears about 8.4 times as large as Deimos in the Martian sky. If we call the radius of Deimos "r", then the radius of the Sun is 8.4r.

Using the information given, we can set up the following equation:

deimos distance / (3,000,000 + r) = 8.4r / (3,000,000)Simplifying and solving for r,

we get:r = 9.39 m (rounded to one significant digit)

To determine which of the given Boolean equations describes the action of the circuit, let's analyze each equation step by step.

A. \( X = (\overline{A \cdot B}) + (B \cdot C) \)

In this equation, \( X \) is the output of the circuit. The first term, \( (\overline{A \cdot B}) \), represents the negation of the logical AND operation between \( A \) and \( B \). The second term, \( (B \cdot C) \), represents the logical AND operation between \( B \) and \( C \). The two terms are then summed using the logical OR operation.

B. \( X = (A \cdot B) \cdot (B + C) \)

In this equation, \( X \) is the output of the circuit. The first term, \( (A \cdot B) \), represents the logical AND operation between \( A \) and \( B \). The second term, \( (B + C) \), represents the logical OR operation between \( B \) and \( C \). The two terms are then multiplied using the logical AND operation.

C. \( X = (\bar{A} \cdot \bar{B}) + (B \cdot C) \)

In this equation, \( X \) is the output of the circuit. The first term, \( (\bar{A} \cdot \bar{B}) \), represents the negation of \( A \) ANDed with the negation of \( B \). The second term, \( (B \cdot C) \), represents the logical AND operation between \( B \) and \( C \). The two terms are then summed using the logical OR operation.

To find the exact solutions for the given initial conditions and state the interval of existence, we will solve each problem step by step and plot the solutions on their respective intervals of existence.

19. The differential equation is \(y' = \frac{x}{y}\), and we have two initial conditions: \(y(0) = 1\) and \(y(0) = -1\).

- For the initial condition \(y(0) = 1\):

 - Rearrange the differential equation as \(ydy = xdx\).

 - Integrate both sides to obtain \(\frac{1}{2}y^2 = \frac{1}{2}x^2 + C\).

 - Apply the initial condition \(y(0) = 1\) to find the constant \(C = \frac{1}{2}\).

 - The solution is \(y = \sqrt{x^2 + 1}\), and the interval of existence is \((- \infty, \infty)\).

- For the initial condition \(y(0) = -1\):

 - Follow the same steps as above, but this time the constant \(C = -\frac{1}{2}\).

 - The solution is \(y = -\sqrt{x^2 + 1}\), and the interval of existence is \((- \infty, \infty)\).

20. The differential equation is \(y' = -\frac{x}{y}\), and we have two initial conditions: \(y(0) = 2\) and \(y(0) = -2\).

- For the initial condition \(y(0) = 2\):

 - Rearrange the differential equation as \(ydy = -xdx\).

 - Integrate both sides to obtain \(\frac{1}{2}y^2 = -\frac{1}{2}x^2 + C\).

 - Apply the initial condition \(y(0) = 2\) to find the constant \(C = -2\).

 - The solution is \(y = \sqrt{4 - x^2}\), and the interval of existence is \((-2, 2)\).

- For the initial condition \(y(0) = -2\):

 - Follow the same steps as above, but this time the constant \(C = 2\).

 - The solution is \(y = -\sqrt{4 - x^2}\), and the interval of existence is \((-2, 2)\).

21. The differential equation is \(y' = 2 - y\), and we have two initial conditions: \(y(0) = 3\) and \(y(0) = 1\).

- For the initial condition \(y(0) = 3\):

 - Rearrange the differential equation as \(dy = (2 - y)dx\).

 - Integrate both sides to obtain \(y = 2x - Ce^{-x}\).

 - Apply the initial condition \(y(0) = 3\) to find the constant \(C = -1\).

 - The solution is \(y = 2x + e^{-x}\), and the interval of existence is \((- \infty, \infty)\).

- For the initial condition \(y(0) = 1\):

 - Follow the same steps as above, but this time the constant \(C = 0\).

 - The solution is \(y = 2x + e^{-x}\), and the interval of existence is \((- \infty, \infty)\).

Note: The solutions for both initial conditions in this problem are the same.

We have found the exact solutions and intervals of existence for the given initial value problems. Now, we can plot each exact solution on its corresponding interval of existence. Additionally, we can use a numerical solver to duplicate the solution curve for each initial value problem.

The equation of best fit is y = (-22/5)x + 10.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The following coordinates are given:

Pick two coordinates.

(0, 10) and (25, -100)

The equation of best fit.

y = mx + c

Now,

m = (-100 - 10) / (25 - 0)

m = -110 / 25

m = -22/5

Now,

(0, 10) = (x, y)

10 = (-22/5) x 0 + c

c = 10

Now,

y = mx + c

y = (-22/5)x + 10

Thus,

Using the coordinates the equation of best fit is y = (-22/5)x + 10.

The quadratic equation that represents the solution is F: p(x) = x² - 49.

The term "quadratic" refers to functions where the highest degree of the variable (in this example, x) is 2. A quadratic function's graph is a parabola, which, depending on the sign of the leading coefficient a, can either have a "U" shape or an inverted "U" shape.

Algebra, geometry, physics, engineering, and many other branches of mathematics and science all depend on quadratic functions. They are used to simulate a wide range of phenomena, including population dynamics, projectile motion, and optimisation issues.

Given that the solution of the quadratic function are x = -7 and x = 7 thus we have:

p(x) = (x + 7)(x - 7)

Solving the parentheses we have:

p(x) = x² - 7x + 7x - 49

Cancelling the same terms with opposite sign we have:

p(x) = x² - 49

Hence, the quadratic equation that represents the solution is F: p(x) = x² - 49.

The integral: S1 0 (-x³ - 2x² - x + 3)dx is -1/12

An integral is a mathematical operation that calculates the area under a curve or the value of a function at a specific point. It is denoted by the symbol ∫ and is used in calculus to find the total amount of change over an interval.

To evaluate the integral:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx $\)

We can integrate each term of the polynomial separately using the power rule of integration, which states that:

\($ \int x^n dx = \frac{x^{n+1}}{n+1} + C $\)

where C is the constant of integration.

So, we have:

\($ \int_0^1 (-x^3 - 2x^2 - x + 3)dx = \left[-\frac{x^4}{4} - \frac{2x^3}{3} - \frac{x^2}{2} + 3x\right]_0^1 $\)

Now we can substitute the upper limit of integration (1) into the expression, and then subtract the result of substituting the lower limit of integration (0):

\($ \left[-\frac{1^4}{4} - \frac{2(1^3)}{3} - \frac{1^2}{2} + 3(1)\right] - \left[-\frac{0^4}{4} - \frac{2(0^3)}{3} - \frac{0^2}{2} + 3(0)\right] $\)

Simplifying:

\($ = \left[-\frac{1}{4} - \frac{2}{3} - \frac{1}{2} + 3\right] - \left[0\right] $\)

\($ = -\frac{1}{12} $\)

Therefore,

Given the ODE using Frobenius Method x²y"+x²y¹-2y = 0The Frobenius method is used to obtain the power series solution of a differential equation of the form:

xy″+p(x)y′+q(x)y=0Which is given in your question as: x²y"+x²y¹-2y = 0The general form of the Frobenius solution can be expressed as a power series of the form:y(x)=x^r ∑_(n=0)^(∞) a_n x^n+rwhere 'r' is any arbitrary constant and the 'a_n' coefficients are determined from the recurrence relation.

The Frobenius method consists of substituting this power series into the differential equation and equating the coefficient of the same powers of x to zero. This method can be used to solve any second-order differential equation having a regular singular point.

Therefore, substituting the given equation we get:$$ x^2 y'' + x^2 y' - 2y = 0 $$Let the solution of the given equation be:y(x) = ∑_(n=0)^(∞) a_n x^(n + r)Substituting this in the differential equation, we get:$$ x^2y'' + x^2y' - 2y = \sum_{n=0}^\infty a_n [(n+r)(n+r-1)x^{n+r} + (n+r)x^{n+r} - 2x^{n+r}] $$Equating the coefficient of each power of x to zero, we get:Coefficients of x^(r):$$ r(r-1)a_0 = 0 \Rightarrow r=0,1 $$Coefficients of x^(r + 1):$$ (r+1)r a_1 + (r+1)a_1 - 2a_0 = 0 $$Taking r = 0, we get:a_1 - 2a_0 = 0a_1 = 2a_0

The solution becomes:y_1(x) = a_0 [1 + 2x]Taking r = 1, we get:$$ 6a_2 + 3a_1 - 2a_0 = 0 $$a_2 = (1/6) [2a_0 - 3a_1]Substituting the value of a_1 from above, we get:a_2 = a_0/3The second solution is given by:y_2(x) = a_0 [x^2/3 - 2x/3]Therefore, the required solution of the given ODE using Frobenius method is:y(x) = c_1 y_1(x) + c_2 y_2(x)y(x) = c_1 [1 + 2x] + c_2 [x^2/3 - 2x/3]

The Miller index notation for the (100) plane in an FCC crystal structure is [100].

Miller indices are a way to describe crystal planes and directions in a standardized manner. In the case of FCC crystal structure, the (100) plane is parallel to the x-y plane and intersects the x-axis, y-axis, and z-axis at points where the Miller indices are (1,0,0), (0,1,0), and (0,0,1), respectively.

However, to express the (100) plane in a concise and standardized manner, we can use the Miller index notation, which involves taking the reciprocals of the intercepts of the plane with the crystallographic axes and then reducing them to the smallest integer values. In the case of the (100) plane in FCC, all of the intercepts are 1, so the Miller indices are [100].

To transform the left side into the right side, we should use the double angle formula for cosine and simplify the left side.

To verify the given identity, we can start by using the double angle formula for cosine, which states that \(cos 2x = cos^2 x - sin^2 x\).

Substituting this expression into the original equation, we get:

\(sin^2 x + (cos^2 x - sin^2 x) = cos^2 x\)

Simplifying the equation further, we have:

\(sin^2 x + cos^2 x - sin^2 x = cos^2 x\)

The \(sin^2 x\) and\(-sin^2 x\) terms cancel each other out, leaving us with:
