The slope of a line perpendicular to the line passing through the points (0,4) and (-3,0) is -3/4.

To find the slope of a line perpendicular to a given line, we need to take the negative reciprocal of the slope of the given line.

Given the points (0,4) and (-3,0), we can calculate the slope of the given line using the slope formula:

slope = (y2 - y1) / (x2 - x1)

Let's substitute the values:

slope = (0 - 4) / (-3 - 0)

= -4 / -3

= 4/3

The slope of the given line is 4/3.

To find the slope of a line perpendicular to this line, we take the negative reciprocal of 4/3:

slope of perpendicular line = -1 / (4/3)

= -1 * (3/4)

= -3/4

Given : Initial value problemd

²x/dt² + 4x

= -2sin(2t) + 5cos(2t)x(0)

= -1, x'(0)

= 1

The solution for the differential equation

d²x/dt² + 4x = -2sin(2t) + 5cos(2t)

is given by,

x(t)

= xh(t) + xp(t)

where, xh(t)

= c₁ cos(2t) + c₂ sin(2t)

is the solution of the homogeneous equation. And, xp(t) is the solution of the non-homogeneous equation. Solution of the homogeneous equation is given by finding the roots of the auxiliary equation,

m² + 4 = 0

Or, m² = -4, m = ± 2i

∴xh(t) = c₁ cos(2t) + c₂ sin(2t)

is the general solution of the homogeneous equation.

The particular integral can be found by using undetermined coefficients.

For the term -2sin(2t),

Let, xp(t) = A sin(2t) + B cos(2t)

Putting in the equation,

d²x/dt² + 4x

= -2sin(2t) + 5cos(2t)

We get, 4(A sin(2t) + B cos(2t)) + 4(A sin(2t) + B cos(2t))

= -2sin(2t) + 5cos(2t)Or, 8Asin(2t) + 8Bcos(2t)

= 5cos(2t) - 2sin(2t)

Comparing the coefficients of sin(2t) and cos(2t),

we get,

8A = -2,

8B = 5Or,

A = -1/4, B = 5/8

∴ xp(t) = -1/4 sin(2t) + 5/8 cos(2t)

Putting the values of xh(t) and xp(t) in the general solution, we get the particular solution,

x(t) = xh(t) + xp(t

)= c₁ cos(2t) + c₂ sin(2t) - 1/4 sin(2t) + 5/8 cos(2t)

= (c₁ - 1/4) cos(2t) + (c₂ + 5/8) sin(2t)

Putting the initial conditions,

x(0) = -1, x'(0) = 1 in the particular solution,

we get, c₁ - 1/4 = -1, c₂ + 5/8 = 1Or, c₁ = -3/4, c₂ = 3/8

∴ The solution of the differential equation is given byx(t)

= (-3/4)cos(2t) + (3/8)sin(2t) - 1/4 sin(2t) + 5/8 cos(2t)

= (-1/4)cos(2t) + (7/8)sin(2t)

Therefore, x(t) = (-1/4)cos(2t) + (7/8)sin(2t).

To reverse the order of integration, we need to rewrite the limits of integration in terms of the other variable.
The value of the given integral by reversing the order of integration is (5/12)(\(e^{24}\) - 1).

The given integral is ∫∫ \(5e^{(2x)}\) dx dy, where the limits of x are from 0 to 4 and the limits of y are from 0 to 3y.
To integrate with respect to y first, we need to express the limits of y in terms of x.
From the limits of y given, we have 0 ≤ y ≤ 3y, which simplifies to 0 ≤ y.
Now we need to find the upper limit of y. To do this, we set the expression for the upper limit equal to the constant 12, which is the upper limit of x.
So we have 3y = 12, which gives y = 4.
Thus, the limits of integration become ∫∫ \(5e^{(2x)}\) dy dx, where the limits of y are from 0 to 4 and the limits of x are from 0 to 3y.
Now we can integrate with respect to y:

∫∫ \(5e^{(2x)}\) dy dx = ∫ 0^4 ∫ 0^(3y) \(\int\limits^4_0 \int\limits^{(3y)}_0 5e^{(2x)} dx dy\)
= \(\int\limits^4_0  [5/2 e^{(2x)}]_0^{(3y)} dy\)
= \(\int\limits^4_0  [5/2 (e^{(6y)} - 1)] dy\)
= \([5/12 (e^{(6y)} - 1)]_0^4\)
= \((5/12)(e^{24} - 1)\)
Note that the order of integration can be reversed if the integrand is continuous on a rectangular region that contains the original region of integration.

The maximum height that the object will reach is 8 feet.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Here, The function of height is,

⇒ f (t) = -16t² + 16t + 4

Notice that, the function is a negative parabola. The maximum of the function is located at the vertex of the parabola. At the vertex, the line tangent to that point is horizontal, i.e., its slope is zero. The slope of the tangent line is the derivative of the function and it also expresses the velocity of the object:

Hence, We get;

df/dt = -32t + 16

At the maximum point, the slope of the tangent line is zero (it is the same as to say that at the maximum height, the velocity of the object is zero), then:

df/dt = 0

0 = -32t + 16

Solving the equation for t:

32t = 16

t = 16/32

t = 0.5 s

Then, the maximum height will be f (0.5):

f (t) = -16 t² + 16t + 4

f (0.5) = -16(0.5)² + 16(0.5) + 4

f (0.5) = - 16 × 0.25 + 8 + 4

f (0.5) = - 4 + 8 + 4

f (0.5) = 8 feet

Thus, The maximum height that the object will reach is 8 feet.

For the required value of the given complex numbers z₁z₂ = 32(cos 255° + isin 255°).

Complex numbers are those that expand on the idea of real numbers by incorporating an illogical element.

The formula for a complex number is "a + bi," where "a" and "b" are real numbers and "i" is the imaginary unit, which is equal to the square root of -1.

"A" stands for the complex number's real component, and "b" stands for the imaginary component.

We multiply the magnitudes of two complex numbers and add their arguments to determine their product.

Let's compute z₁z₂ with the supplied values.

Given:

z₁ = 8(cos 45° + isin 45°)

z₂ = 4(cos 210° + isin 210°)

We add the arguments and multiply the magnitudes to find z₁z₂:

Magnitude of z₁ = 8

Magnitude of z₂ = 4

Argument of z₁ = 45°

Argument of z₂ = 210°

Now, let's calculate z₁z₂:

Magnitude of z₁z₂ = (Magnitude of z₁) × (Magnitude of z₂) = 8 × 4 = 32

Argument of z₁z₂ = (Argument of z₁) + (Argument of z₂) = 45° + 210° = 255°

Therefore, z₁z₂ = 32(cos 255° + isin 255°).

The slope of a line is undefined when the line is vertical. In this case, the line does not have a well-defined slope because its rise (change in y) would be infinite while its run (change in x) would be zero.

In general, the slope of a line represents the rate at which the line rises or falls as it moves from left to right. It is defined as the change in y divided by the change in x between any two points on the line.

If the slope of a line is positive, the line is sloping upward from left to right, and if the slope is negative, the line is sloping downward from left to right. If the slope is zero, the line is horizontal. When the slope is undefined, it means that the line is vertical, and it has no well-defined rate of rise or fall as it moves from left to right.

Answer: 1/50

Step-by-step explanation:

Step 1: We need to multiply the numerator and denominator by 100 since there are 2 digits after the decimal.

0.02 = (0.02 × 100) / 100

= 2 / 100 [ since 0.02 × 100 = 2 ]

Step 2: Reduce the obtained fraction to the lowest term

Since 2 is the common factor of 2 and 100 so we divide both the numerator and denominator by 2.

2/100 = (2 ÷ 2) / (100 ÷ 2) = 1/50

Systematic Sampling is the probability sampling method involves selecting large, broad groups rather than individuals.

Systematic sampling is a type of probabilistic sampling technique that selects sample members from a larger population according to random starting points, but with regular periodic intervals. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.

Systematic sampling is a type of probabilistic sampling technique that selects sample members from a larger population at regular periodic intervals according to random starting points. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size. Systematic sampling is considered random if the regular intervals are predetermined and the starting point is random, even though it preselects the sample population.

Systematic sampling, when performed correctly on large populations of a defined size, allows researchers, including marketing and sales professionals, to obtain representative results on large groups of people. without having to contact each individual. Example, if we select a random group of 1,000 people from a population of 50,000 by systematic sampling, we should list all potential participants and choose a starting point. When the list is created, every 50th of her on the list (starting counting from the starting point you chose) will be selected as participants because 50,000 ÷ 1,000 = 50.

When 293 college students are randomly selected and surveyed, it is found that 114 own a car. The upper limit for the 90% confidence interval for the percentage of all college students who own a car is 46.3%.

The given problem is an example of confidence intervals in statistics. The formula for finding the confidence interval in percentage is given below:

Confidence Interval in Percentage = P ± Z Score x √ (PQ/n)

where

P = Sample proportion

Q = 1 - P

n = Sample Size

Z Score is obtained from the Z-Table where the confidence level is given.

To obtain the upper limit, the following formula should be used:

Upper Limit of the Confidence Interval = P + Z Score x √ (PQ/n)

Substitute the given values of the question into the formula:

P = 114/293 = 0.3891

Q = 1 - 0.3891 = 0.6109

n = 293

The upper limit for the 90% confidence interval is given by the Z-Table at 1.645:

Upper Limit of the Confidence Interval = 0.3891 + 1.645 x √ [(0.3891 x 0.6109)/293]

≈ 0.3891 + 1.645 x 0.0467

≈ 0.3891 + 0.07701

≈ 0.4661 = 46.3%

Therefore, the answer is 46.3%.

A linear transformation is a function between two vector spaces that preserves the structure of the space, namely the operations of addition and scalar multiplication. More specifically, a function T:V->W is a linear transformation if it satisfies the following properties:

T(u+v) = T(u) + T(v) for all u,v in V (additivity)

T(cu) = cT(u) for all u in V and scalar c (homogeneity)

In other words, a linear transformation preserves vector addition and scalar multiplication. It takes vectors as inputs and outputs new vectors that are also in the vector space. Additionally, a linear transformation must satisfy the following properties:

T(0) = 0, where 0 is the zero vector in V (preservation of the zero vector)

If T is a linear transformation from V to W, then T must map the basis vectors of V to linearly independent vectors in W.

Some examples of linear transformations include rotation, scaling, and projection.

Linear transformations are important in many areas of mathematics and science, including linear algebra, calculus, and physics. They are used to study a wide variety of phenomena, from the motion of planets to the behavior of complex systems.
