what is the arcsin of 3

A mx n matrix with more rows than columns has full rank if and only if the columns are linearly independent. It is a common requirement in statistical theory that a matrix be of full rank.

The rank should be as large as possible. Let us consider the system Ax = 0, where A is an m x n matrix with m > n. The correct answer is option A. Here's the explanation:

Since the rank of A is the number of pivot positions that A has and A is assumed to have full rank, rank A= n. By the Rank Theorem, dim Nul A= n-rank A= 0. So Nul A does not contain only the trivial solution. This happens if and only if the columns of A are linearly independent.

Hence, option A is the correct answer.

Answer:

(1, - 1.5 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then

midpoint = ( \(\frac{x_{1}+x_{2} }{2}\) , \(\frac{y_{1}+y_{2} }{2}\) )

here (x₁, y₁ ) = (4, 0 ) and (x₂, y₂ ) = (- 2, - 3 ) , then

midpoint = ( \(\frac{4-2}{2}\) , \(\frac{0-3}{2}\) ) = ( \(\frac{2}{2}\) , \(\frac{-3}{2}\) ) = (1, - 1.5 )

(1, -1.5).

Step-by-step explanation:

The midpoint of a segment with endpoints (x1, y1) and (x2, y2) is given by the following formula:

((x1 + x2)/2, (y1 + y2)/2)

So, for the given endpoints (4,0) and (-2,-3), the midpoint is:

((4 + (-2))/2, (0 + (-3))/2) = (1, -1.5)

The midpoint of the segment is (1, -1.5).

The largest area a rectangle can have when inscribed in a semicircle of radius 2 is 4 square units.

The dimensions of this rectangle are 2 units by 2 units. This occurs when the sides of the rectangle are parallel to the diameter of the semicircle, so that each vertex of the rectangle lies on the circumference of the semicircle.

The length of the rectangle is equal to the diameter of the semicircle, or 2 units, and its width is half the diameter, or 2/2 = 1 unit. The area of this rectangle is equal to the length times the width, or 2 * 1 = 2 square units.

Since the rectangle is inscribed in a semicircle, its dimensions must be equal, so the largest area rectangle that can be inscribed in a semicircle of radius 2 has sides of length 2 units and an area of 4 square units.

Step-by-step explanation:

Signed and unsigned integer expressions differ in how they interpret and represent numerical values. Signed integers can represent both positive and negative values, while unsigned integers can only represent non-negative values.



1. Signed Integer Expressions: Signed integers are capable of representing positive, negative, and zero values. They allocate a bit for the sign, typically using the leftmost bit (the most significant bit). The remaining bits are used to represent the magnitude of the number. The sign bit is set to 0 for positive or zero values and set to 1 for negative values. This representation allows for a wider range of values, but half of the possible bit patterns are reserved for negative numbers, limiting the maximum positive value that can be represented.

2. Unsigned Integer Expressions: Unlike signed integers, unsigned integers do not allocate a bit for the sign. Instead, all bits are used to represent the magnitude of the number, allowing for a wider range of non-negative values. As a result, unsigned integers can represent larger positive values than their signed counterparts. However, they cannot represent negative values or zero, as there is no reserved bit to indicate the sign.

The choice between signed and unsigned integer expressions depends on the specific requirements of a program. Signed integers are typically used when negative values need to be represented or when arithmetic operations may result in negative values. On the other hand, unsigned integers are useful when dealing with quantities that are always expected to be positive, such as array indices or lengths of data structures. It's important to consider the range of values required and the potential impact of overflow or underflow when selecting between signed and unsigned integer expressions.

The equation of the plane is ⟨0, 0, -xt, -y⟩. ⟨(x-1), y, z, t⟩ = 0.

Given that the equation for the line is x, y, z, t.

The equation for the plane perpendicular to the given line can be calculated as follows:

Firstly, we know that the vector which is perpendicular to both the line and the plane is the direction of the plane.

Hence the direction of the plane is the cross product of the vector with the given line direction:⟨1, 0, 0, 0⟩ × ⟨x, y, z, t⟩= ⟨0t - 0z, 0z - 0t, 0y - xt, 0x - y⟩= ⟨0, 0, -xt, -y⟩Hence the direction of the plane is ⟨0, 0, -xt, -y⟩.

Now, we need to find any point (x0, y0, z0, t0) on the plane.

Let's assume that the point is (1, 0, 0, 0) since it lies on the line.

Then the equation of the plane can be obtained as:⟨0, 0, -xt, -y⟩ .

⟨(x-x_0), (y-y_0), (z-z_0), (t-t_0)⟩ = 0⟨0, 0, -xt, -y⟩ . ⟨(x-1), y, z, t⟩ = 0

The equation of the plane perpendicular to the line x, y, z, t is given as ⟨0, 0, -xt, -y⟩. ⟨(x-1), y, z, t⟩ = 0.

Therefore, the equation of the plane is ⟨0, 0, -xt, -y⟩. ⟨(x-1), y, z, t⟩ = 0.

Step-by-step explanation:

Option A

Option A is false because the opposite of -12 is 12. -1/12 is the reciprocal of -12. Hence, Option A is false.

Option B

Option B is true because the opposite of -12 is 12 and the opposite of 12 is -12. Hence, Option B is true.

Option C

Option C is false because it is not located on the same side of zero on a number line. Positives and negatives are separated. Hence, this is false.

Option D

Option D is true because if we take -1 as an example, the opposite of -1 is 1. We can clearly see that both numbers are 1 away from 0. Hence, Option D is true

After working on the problem, we can conclude that Option B and D are true.

We have the following equation

so the percent increase is 25%

The speed of the particle when it is moving parallel to the y-axis is approximately 17.88 m/s.

When the particle moves parallel to the y-axis, its velocity component in the x-direction is zero. Therefore, we need to find the value of t for which the x-component of the velocity becomes zero.

Given that the x-component of the velocity is (2t - 8), we set it equal to zero and solve for t:

2t - 8 = 0

2t = 8

t = 4

At t = 4 seconds, the particle is moving parallel to the y-axis. To determine the speed of the particle at this instant, we calculate the magnitude of its velocity:

v = √[(2t - 8)^2 + ((2/t^2) - 18)^2]

v = √[(2(4) - 8)^2 + ((2/(4^2)) - 18)^2]

v = √[0^2 + ((2/16) - 18)^2]

v = √[0 + (-17.875)^2]

v ≈ 17.88 m/s

Therefore, the speed of the particle when it is moving parallel to the y-axis is approximately 17.88 m/s.

20 ft/sec must she let out the string when the kite is 500 ft away from her.

What is rate?

A rate is a unique ratio where the two words are expressed in several units.

For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. Cents and ounces are the two dissimilar units in this ratio.

Let x = distance of girl from the point on the ground directly below the     kite at time t

y = length of string at time t

At time t, we have a right triangle with horizontal leg of length x, vertical leg of length 300, and hypotenuse of length y.

Given:  dx/dt = 25

Find:  dy/dt when y = 500

By the Pythagorean Theorem, \(x^2 +300^2 = y^2\)

Differentiating both sides, with respect to t,

\((2x)\frac{dx}{dt} = 2y\frac{dy}{dt}\)           ...(1)

Since, \(x^2 +300^2 = y^2\),  y = 500,

So, x = 400

Plug these values in equation (1).

\(2(400)(25) = 2(500)\frac{dy}{dt}\)

After solving,

\(\frac{dy}{dt} = 20 ft/sec\)

Therefore, 20 ft/sec must she let out the string when the kite is 500 ft away from her.

The condition for a portfolio to be self-financing in the Black-Scholes model is that the portfolio's value does not change due to trading (buying or selling) costs or external cash flows. In other words, the portfolio's value remains constant over time, excluding the effects of the underlying assets' price changes.

For the given portfolio, a = -t (units of the stock) and b = S_t (units of the savings account). To determine if this portfolio is self-financing, we need to check if its value remains constant over time. Using Ito's lemma, we can express the value of the portfolio as:

d(Vt) = a_t * d(St) + b_t * d(Ct)

Substituting the values of a and b, we have:

d(Vt) = -t * (2St * dt + 4St * dBt) + S_t * d(t)

Simplifying this expression, we get:

d(Vt) = -2tSt * dt - 4tSt * dBt + S_t * dt

The portfolio is self-financing if d(Vt) = 0. However, in this case, we can see that the terms involving dBt do not cancel out, indicating that the portfolio is not self-financing.

The ladder needs to make an angle of approximately 54.7 degrees with the house in order for Brigid to reach 18 feet up the side of the house.

To determine the angle the ladder needs to make with the house, we can use the tangent function.

First, we'll need to determine the opposite side (the height that the ladder needs to reach) and the adjacent side (the distance from the base of the ladder to the house) of the triangle formed by the ladder and the house.

Opposite side = 18 feet

Adjacent side = 25 feet

We can then use the tangent function to find the angle:

tan(angle) = opposite / adjacent

Solving for the angle, we get:

angle = arctan(18/25) = approximately 54.7 degrees

Therefore, the ladder needs to make an angle of approximately 54.7 degrees with the house in order for Brigid to reach 18 feet up the side of the house.

The measure of angle EBF is  80° .

In the question ,

it is given that ,

point A, B and C lie on a straight line .

and G , B and F lie on a different straight line .

angle GBA = 24° so ,

GBA + GBC = 180°   ...because linear pair

So , GBC = 180 - 24 = 156°

angle CBF = 24°          ......because vertically opposite angles are equal .

from the figure , we see that angle GBC and angle ABF are vertically opposite angles , so ,

156° = ABE + EBF         .....(1)

Since the line AC and DF are parallel and BE is the transversal

So  , angle DEB + angle ABE = 180°

104° + ABE = 180°

ABE = 180-104

ABE = 76°

Substituting ABE = 76° in the equation (1) ,

we get ,

156 = 76+ EBF

EBF = 156 - 76

EBF = 80°

Therefore , The measure of angle EBF is  80° .
