Given equation is a first-order nonlinear ordinary differential equation (ODE): y' - (x + y - 1)^2 = 0

What is differential equation ?

A differential equation is an equation that contains at least one derivative of an unknown function, either a normal differential equation or a partial differential equation.

This equation can be solved using various methods, such as numerical methods or analytical methods like the implicit function theorem or the method of characteristics. However, finding an exact solution can be challenging and may not always be possible.

If you would like to find an approximate solution to this ODE, you could use numerical methods such as Euler's method, Runge-Kutta method, or the finite difference method. These methods can provide a numerical approximation to the solution for a given range of x and a specified initial condition.

Answer:6

Step-by-step explanation:

Let the number be x.

Now, 3x+6=24

3x=24-6

3x=18

x=18/3

x=6

Answer:

6

Step-by-step explanation:

We can work the problem backwards

Since something gives 24 that means it equals 24

= 24

Something increased by 6, so something added by 6

Something + 6 = 24

Making something = x

x + 6 = 24

If we subtract 6 from both sides

x = 18

Trice a number, so divide this number by 3

x = 6

Trice of 6 is 18... 18 increased by 6 gives 24

The volume of the rectangular prism given the length, width and height is 6 14/27 cubic feet.

The correct answer choice is option B

Volume of a rectangular prism= length × width × height

Length= 1 5/6 ft

Width = 1 1/3 ft

Height = 2 2/3 ft

Volume of a rectangular prism= length × width × height

= 1 5/6 × 1 1/3 × 2 2/3

= 11/6 × 4/3 × 8/3

The required point of intersection of the two lines is (-2, 7/3).

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

The equation "y = 2/3x + 3" represents a line in the coordinate plane. It has a slope of 2/3 and a y-intercept 3. The equation "x = -2" represents a vertical line. It has no slope and the x-coordinate of all its points is -2.

Since the two equations represent lines, we can find their point of intersection by setting the two equations equal to each other and solving for y.

So, we have:

2/3x + 3 = y

and

x = -2

Substituting x = -2 into the first equation, we get:

2/3(-2) + 3 = y

Solving for y:

y = -2/3 * -2 + 3 = 4/3 + 3 = 7/3

Thus, the point of intersection of the two lines is (-2, 7/3).

The triangle PQR is an equilateral triangle

From the question, we have the following parameters that can be used in our computation:

PQ=QR.

m/P = (2x - 26) and m/R= (x+17)

When two sides of a triangle are congruent, then the triangle is an isosceles triangle

Using the above as a guide, we have the following:

2x - 26 = x + 17 --- base angles of an isosceles triangle

So, we have

x = 43

This gives

m/P = 2 * 43 - 26 = 60

m/R= 43 + 17 = 60

If two angles of a triangle measure 60 degrees, then the third angle is 60 degrees

Step-by-step explanation:

The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

The area enclosed by the curve y = -x² and y = x² - i is the difference of the areas between these two curves.

To find the area enclosed by the curve y = x², we need to find its definite integral with respect to x from -∞ to ∞.

The definite integral of y = x² with respect to x from -∞ to ∞ is:

∫[-∞,∞] x² dx = (x³/3) from -∞ to ∞

Since the definite integral of an infinite function from -∞ to ∞ is undefined, we cannot find the exact value of the area enclosed by the curve y = x².

However, we can use the definite integral of y = x² - i with respect to x from -∞ to ∞ to find the area enclosed by the curve y = x² - i:

∫[-∞,∞] (x² - i) dx = (x³/3 - i * x) from -∞ to ∞

Again, the definite integral of an infinite function from -∞ to ∞ is undefined, so we cannot find the exact value of the area enclosed by the curve y = x² - i.

Since the area enclosed by the curve y = -x² is the same as the area enclosed by the curve y = x² but with the opposite sign, the difference of the areas enclosed by the two curves is equal to 56:

Area enclosed by y = x² - i - Area enclosed by y = -x² = 56

The first equation, y = -x^2, is a parabola that opens downwards.

The second equation, y = x^2 - i, is also a parabola but is translated downward by i units.

The area enclosed by the two curves will be the difference between the area under y = -x^2 and the area under y = x^2 - i.

The area under y = -x^2 can be calculated as follows:

A = ∫[-a,a] -x^2 dx = -(1/3) x^3 |^a_-a = (1/3) a^3

Where a is the x-value at which the two curves intersect.

The area under y = x^2 - i can be calculated as follows:

B = ∫[-a,a] (x^2 - i) dx = (1/3) x^3 - i x |^a_-a = (1/3) a^3 - i a

The area enclosed by the two curves is then given by:

C = B - A = (1/3) a^3 - i a - (1/3) a^3 = -i a

Since we know that the area enclosed by the curves is 56, we can set up the equation:

-i a = 56

So,

i = -56/a

Since a value is unknown, we cannot determine the exact value of i. However, we can use this equation to find the value of i for different values of a.

Therefore, The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

Again, the definite integral of an infinite function from -∞ to ∞ is undefined, so we cannot find the exact value of the area enclosed by the curve y = x² - i.

Since the area enclosed by the curve y = -x² is the same as the area enclosed by the curve y = x² but with the opposite sign, the difference of the areas enclosed by the two curves is equal to 56:

The area enclosed by the two curves will be the difference between the area under y = -x^2 and the area under y = x² - i.

The area under y = -x^2 can be calculated as follows:

A = ∫[-a,a] -x²dx = -(1/3) x³ |^a_-a = (1/3) a³

Where a is the x-value at which the two curves intersect.

The area under y = x^2 - i can be calculated as follows:

B = ∫[-a,a] (x² - i) dx = (1/3) x³ - i x |^a_-a = (1/3) a³ - i a

The area enclosed by the two curves is then given by:

C = B - A = (1/3) a³ - i a - (1/3) a³ = -i a

Since we know that the area enclosed by the curves is 56, we can set up the equation:

-i × a = 56

So,

i = -56/a

Since a value is unknown, we cannot determine the exact value of i. However, we can use this equation to find the value of i for different values of a.

Therefore, The value of i is -56/a, Since the value of a is unknown, we cannot determine the exact value of i.

QUESTION CORRECTION: Find the value of i for which the area enclosed by the curve =−x² and =x²− i equal to 56.

The correct answer is log(x^(x)) = x * log(x).

The logarithmic rule states that log(a^b) = b * log(a).

So, let's apply this rule to log(x^(x)):

log(x^(x)) = x * log(x)

On the right side of the equation, x represents the exponent and log(x) represents the base.

This equation states that the logarithm of x raised to the power of x is equal to x times the logarithm of x.

Now let's simplify the other options:

x * log(x) is already simplified from the equation above, so we don't need to change it.

log(x) * log(x) is simply the logarithm of x raised to the power of 2, which is not equal to the logarithm of x raised to the power of x.

log(x) is the logarithm of x with a base of 10, and log(x) log(x) does not have a valid mathematical interpretation.

Therefore, the correct answer is log(x^(x)) = x * log(x).
