Write an equation for a line perpendicular to y= -5x-1 and passing through the point of (10,3)

The solutions that match the given differential equation are a)y=0 and b)y=2x.

The differential equation is a homogeneous linear differential equation with constant coefficients, which can be written in the form of y" + p(x)y' + q(x)y = 0. The general solution to this type of equation is y = c1e^(rx) + c2e^(rx) where r is the root of the characteristic equation r^2 + p(x)r + q(x) = 0.

In this case, the equation is of the form xy'' - y' = 0. By dividing both sides by x, we get y'' - (1/x)y' = 0, which is a homogeneous linear differential equation with constant coefficients. The characteristic equation is r^2 - (1/x)r = 0. The roots of this equation are r1 = 0 and r2 = 1/x.

Therefore, the general solution to this differential equation is y = c1 + c2x.

y=0 is a solution of the differential equation since it satisfies the equation when plugged in.

y=2x is also a solution of the differential equation since it also satisfies the equation when plugged in.

y=2x^2 and y=2 are not solutions of the differential equation because when plugged into the equation they don't satisfy it.

Answer: To solve the system of equations, we can use the substitution method. We'll start by isolating one of the variables in one of the equations.

The first equation is 3x - 2y = 17

We can solve for x by adding 2y to both sides:

3x = 17 + 2y

x = (17 + 2y)/3

We can substitute this expression for x into the second equation:

5((17 + 2y)/3) + 3y = 5

Simplifying, we get:

50 + 10y + 3y = 5

13y = -45

y = -3.5

Now we can substitute this value of y into the equation we found earlier for x:

x = (17 + 2(-3.5))/3

x = (17 - 7)/3

x = 10/3

x = 3.333

So the solution of the system of equations is (x,y) = (3.333, -3.5)

Which is not in the options provided, so the answer is no solution.

What is ratio?

A ratio is a way of comparing two or more values or quantities. It expresses the relationship between the size of one value or quantity to the size of another. Ratios are often written as fractions or as ":".

The Federal Reserve is making nickels with a constant of proportionality. This can be determined by analyzing the relationship between the amount of nickels made and the time elapsed. If the number of nickels made is directly proportional to the time elapsed, then the ratio between the number of nickels made and the time elapsed will be constant.

As we can see from the table, the ratio between the number of nickels made and the time elapsed is constant, which is 6000 nickels per hour. This means that the Federal Reserve is making nickels with a constant of proportionality.

So, the solution is x = 1, y = -1, z = 3.

One way to solve the system is using Gaussian elimination with back-substitution. The steps are:

1. Rewrite the system in matrix form, called the augmented matrix:

[3 3 6 | 9]

[1 1 2 | 3]

[2 5 10| 15]

[-1 2 4 | 6]

2. Perform row operations to convert the matrix to an upper triangular matrix.

[1 1 2 | 3]

[0 2 4 | 3]

[0 2 6 | 6]

[0 0 -2 | -6]

3. Use back-substitution to find the values of the variables. Starting with the last equation:

-2z = -6 => z = 3

4y + 6(3) = 6 => y = -1

x + 2(-1) + 2(3) = 3 => x = 1

So, the solution is x = 1, y = -1, z = 3.

Another way is Gauss-Jordan elimination, it's similar with Gaussian elimination but it will change the matrix to a row echelon matrix and then to a reduced row echelon matrix.

So, the solution is x = 1, y = -1, z = 3.

Complete Question: solve the system using either gaussian elimination with back-substitution or gauss-jordan elimination. (if there is no solution, enter no solution. if the system has an infinite number of solutions, express x, y, and z in terms of the parameter t.)                                                                                                              3x + 3y + 6z = 9

Answer:

the answer is B (0, -2)

Step-by-step explanation:

To find the point on the curve y = -x^2 - 2 that is closest to the point (0,1), we can use the method of least squares.

The method of least squares involves finding the point on the curve that minimizes the square of the distance between the point and the curve.

To begin, we can define a function d(x) = (y - (-x^2 - 2))^2 which represents the square of the distance between the point (x,y) on the curve and the point (0,1)

then we need to find the derivative of d(x) and set it to zero to find the minimum,

d'(x) = 2(y + x^2 + 2 - 1) = 2(y + x^2 + 1)

by setting d'(x) = 0 we get y = -x^2 - 1,

so the point on the curve that is closest to (0,1) is (0, -1) and the answer is B (0, -2)

Note that the point (0,-1) is on the curve y = -x^2 - 2 but not the point on the closest.

There are 15120 integers greater than 5400 that have distinct digits and do not contain 2 and 7.

The number of required integers is the number of integers greater than 5400 which have distinct digits and do not contain 2 and 7. This can be calculated with the formula:

Number of Required Integers = (9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) - (2 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1) = 30240 - 15120 = 15120.

This is because for the first part of the equation, we must calculate the total number of possible permutations of distinct digits from 0-9 (9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1). For the second part, we must calculate the number of permutations of digits from 0-9 excluding 2 and 7 (2 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1). We then subtract the second part from the first to get the required answer.

An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value e.g. 5 < 6, x ≥ 2, etc.

PART 1

First, solve for x in 9.5x -1.25 < 32

9.5x -1.25 < 32

9.5x < 32 + 1.25

9.5x < 33.25

x < 33.25/9.5

x < 3.5

Since x < 3.5, the circle of the graph will not be shaded. Thus, the second graph is the graph of x < 3.5.

PART 2

The graph of the inequality shown there is x ≤ 5. Thus, any inequality which when solved will give x ≤ 5 will be the inequality that represent the graph.

Let's try (1/5)x - 3/5  ≤ 1/5 and see:

(1/5)x - 3/5  ≤ 1/5

(1/5)x ≤ 1/5 + 3/5

(1/5)x ≤  4/5

x ≤ 4

This is not the inequality

Let's try (2/5)x - 4/5  ≤ 1 1/5:

(2/5)x - 4/5  ≤ 1 1/5

(2/5)x - 4/5 ≤ 6/5

(2/5)x ≤ 6/5 + 4/5

The volume of the toy is 35cm^3. The solution has been obtained using the formula of triangular pyramid.

What is a triangular pyramid?

A triangular pyramid has a triangle-shaped base, and its apex is where the three triangular faces converge. There is a unique type of triangular pyramid called a tetrahedron, which features equilateral triangles on each face. The formula for a triangular pyramid consists of the volume and surface area of the pyramid, which are used to determine the height and slant height as well as the three triangular-shaped sides.

In the given figure, x represents the base(b), y represents the base height(h) and z represents the height(H).

Let's first find the pyramid's base area(B) which is given by;

⇒B = 1/2 * b * h

⇒B = 1/2 * 3 * 7

⇒B = 10.5cm^2

The volume of the toy is given by:

⇒V = 1/3 * B * H

⇒V = 1/3 * 10.5 * 10

⇒V = 35cm^3

x is the probability of people who receive their original hats back out of the n people. All possible re-assignments are equally likely.

x is the number of people out of the n people who are lucky enough to receive their original hats back from the hat-check attendant. All possible re-assignments of hats to people are equally likely. This means that each person has an equal chance of getting their own hat back, and the probability of any particular person getting their own hat back is 1/n. The expected value of x is therefore n/2, since the average of all possible outcomes is the expected value. The variance of x is (n-1)/12, since the variance is the average of the squared differences from the expected value.

Answer:

x^3+1/x^3 = x^2

Step-by-step explanation:

If x^2+1/x^2 =1

The equation x^2+1/x^2 =1 states that the sum of the square of x and the reciprocal of x squared is equal to 1. We can multiply both sides of this equation by x(x+1/x) which is x^2 + 1.

This gives us (x^2)(x+1/x) = x^3 + 1/x^3 = 1.

So, x^3+1/x^3 = x^2.

that x^2+1/x^2 =1, we can deduce that x^3+1/x^3 = x^2. This is because we multiplied both sides of the first equation by x^2 + 1/x^2,

which is equal to x^3+1/x^3 = x^2

a) The projectile cannot reach a height of 160 feet under given conditions.

b) The projectile takes a time of 2 second to hit the ground.

In this question we find the case of a project under free fall, that is, a vertical uniformly accelerated motion due to action of gravity, whose formula is shown below:

s = - 16 · t² + v₀ · t

Where:

Part A - If we know that v₀ = 32 ft / s and s = 160 ft, then the time associated is:

- 16 · t² + v₀ · t - s = 0

- 16 · t² + 32 · t - 160 = 0

By quadratic formula:

t₁ = 1 + i 3, t₂ = 1 - i 3

It is physically impossible to reach a height of 160 feet under conditions given.

Part B - If we know that s = 0 ft and v = 32 ft / s, then the final time is:

- 16 · t² + v₀ · t - s = 0

- 16 · t² + 32 · t = 0

- 16 · t · (t - 2) = 0
