An object is moving along the x x -axis. At t t = 0 it is at x x = 0. Its x x -component of velocity vx v x as a function of time is given by vx(t)=αt−βt3 v x ( t ) = α t − β t 3 , where α= α = 7.2 m/s2 m / s 2 and β= β = 4.8 m/s4 m / s 4  the nonzero time at which x = 0 is 1.22 seconds.

To find the time at which the object is again at x=0, we need to solve the equation vx(t) = 0, which gives us:

αt - βt^3 = 0

t(α - βt^2) = 0

The solutions to this equation are t = 0 (which corresponds to the initial position) and t = ±√(α/β). Since we're looking for a nonzero time, we can discard the t = 0 solution and take t = √(α/β):

t = √(α/β) = √(7.2 m/s^2 / 4.8 m/s^4) = √(1.5 s^2) = 1.22 s

Therefore, the object is again at x=0 after a time of 1.22 seconds.

The left side of the function, can be simplified using trigonometric identities as follows;

csc²(x)·cos²(x) = csc²(x)·(1 - sin²(x)) = csc²(x) - 1

Trigonometric identities are equations that consists of trigonometric functions that are valid for the values of the input variable of the functions.

The specified trigonometric function is presented as follows;

csc²(x)·cos²(x) = csc²(x) - 1

cos²(x) = 1 - sin²(x)

Therefore;

csc²(x)·cos²(x) = csc²(x) × (1 - sin²(x)) = csc²(x) - csc²(x) × sin²(x)

csc²(x)·cos²(x) = csc²(x) - csc²(x) × sin²(x)

csc²(x) = 1/(sin²(x)), therefore;

csc²(x)·cos²(x) = csc²(x) - csc²(x) × sin²(x) = csc²(x) - (1/(sin²(x))) × sin²(x)

(1/(sin²(x))) × sin²(x) = sin²(x) × (1/(sin²(x))) = 1

csc²(x) - (1/(sin²(x))) × sin²(x) = csc²(x) - (1/(sin²(x))) × sin²(x) = csc²(x) - 1

csc²(x)·cos²(x) = csc²(x) - (1/(sin²(x))) × sin²(x) = csc²(x) - 1

Therefore;

csc²(x)·cos²(x) = csc²(x) - 1

A continuous variable is a variable that can take on any value within a certain range, and often takes the form of real numbers but a discrete variable is a variable that can only take on specific values within a certain range, and often takes the form of integers

Continuous and discrete variables are two types of quantitative variables in statistics.

A continuous variable is a variable that can take on any value within a certain range, and often takes the form of real numbers. Examples of continuous variables include height, weight, time, temperature, and distance. These variables can be measured using instruments with varying degrees of precision, but they can theoretically take on an infinite number of values.

On the other hand, a discrete variable is a variable that can only take on specific values within a certain range, and often takes the form of integers. Examples of discrete variables include the number of siblings a person has, the number of cars in a parking lot, and the number of points a basketball team scores in a game. These variables can only take on a limited number of values, and often represent counts or whole numbers.

The main difference between continuous and discrete variables is the way they can be measured and the number of possible values they can take. Continuous variables can take on an infinite number of values and can be measured with varying degrees of precision, while discrete variables can only take on specific values and are often measured with exact precision.

Answer:

ED = 57 , AB = 19

Step-by-step explanation:

the midsegment FC is half the sum of the parallel bases , that is

[tex]\frac{AB+ED}{2}[/tex] = FC

[tex]\frac{4x+3+18x-15}{2}[/tex] = 38 ( multiply both sides by 2 )

At 7 a.m., the temperature was 2°.

Temperature is a measure of the average kinetic energy of particles in a system, measured in degrees on a specific scale (such as Celsius or Fahrenheit). The higher the temperature, the faster the particles move. Temperature is also related to heat, which is the transfer of energy between two systems at different temperatures. Heat always flows from a higher temperature system to a lower temperature system. In addition, temperature is related to pressure, which is the force exerted by the particles in a system. When the temperature of a system increases, so does the pressure.

At 7 a.m., the temperature was 2°. This is because temperatures dropped by 2° per hour until 2 o'clock in the morning. In the 6 hours (from 2 a.m. to 8 a.m.) there were 12° of decrease in temperature (2° per hour x 6 hours). This means that the temperature at 7 a.m. was -6° (2° - 12° = -6°).

The curve of a normal distribution, also known as a Gaussian distribution, is a bell-shaped curve that is symmetric around the mean.

The shape of the curve is determined by two parameters: the mean (µ) and the standard deviation (σ) of the distribution. The curve is highest at the mean, and falls off gradually as we move away from the mean in either direction.

The standard deviation controls the width of the curve, with larger values of σ resulting in wider, flatter curves, and smaller values of σ resulting in narrower, more peaked curves.

The normal distribution is a continuous probability distribution, and it is widely used in statistics to model many natural phenomena, such as the heights of people, the weights of objects, and the scores on tests. It is also commonly used in statistical inference and hypothesis testing.

Step-by-step explanation:

Since the hexagon is regular, all of its sides have the same length. Therefore, each side has a length of 57 inches / 6 = 9.5 inches.

To find the area of the hexagon, we can use the formula:

Area = (3√3 / 2) × s^2

where s is the length of a side.

Substituting s = 9.5 inches, we get:

Area = (3√3 / 2) × (9.5 inches)^2

Area ≈ 244.3 square inches

Rounding to the nearest tenth, the area of the hexagon is 244.3 square inches.

For a regular pentagon, the apothem is the distance from the center of the pentagon to the midpoint of one of its sides. We can use the formula for the area of a regular pentagon to find the apothem:

Area = (5/4) × apothem × side length

Substituting the given values, we get:

118.25 square meters = (5/4) × apothem × (4.3 meters)

apothem = 118.25 square meters / (5/4) / (4.3 meters)

apothem ≈ 8.4 meters

Therefore, the length of the apothem is approximately 8.4 meters.

Since the hexagon is regular, all of its sides have the same length. Therefore, each side has a length of 90 feet / 6 = 15 feet.

To find the area of the hexagon, we can use the same formula as in the first problem:

Area = (3√3 / 2) × s^2

Substituting s = 15 feet, we get:

Area = (3√3 / 2) × (15 feet)^2

Area ≈ 1161.4 square feet

Rounding to the nearest tenth, the area of the hexagon is 1161.4 square feet.

In reference to the question given, the mean absolute deviation of the set {6, 8, 8, 12, 16} is 2.4.

To find the mean absolute deviation of a set of numbers, we first need to calculate the deviations of each number from the mean of the set, then take the absolute value of each deviation, and finally calculate the average of all the absolute deviations.

To find the mean of the set {6, 8, 8, 12, 16}, we first need to calculate the mean:

mean = (6 + 8 + 8 + 12 + 16) / 5 = 10

Next, we calculate the deviations of each number from the mean:

|6 - 10| = 4

|8 - 10| = 2

|8 - 10| = 2

|12 - 10| = 2

|16 - 10| = 6

Taking the absolute value of each deviation gives us:

4, 2, 2, 2, 6

Finally, we calculate the mean of these absolute deviations:

mean absolute deviation = (4 + 2 + 2 + 2 + 6) / 5 = 2.4

The rank-nullity theorem states that the rank of a matrix plus the dimension of its null space equals the number of columns.

Thus, if the null space of a 4 x 5 matrix is three-dimensional, then the rank of the matrix is 5 - 3 = 2.

Answer to Question 2:

The dimension of the solution space of A x = 0 is 6 - 2 = 4, since the number of columns of A is 6 and its rank is 2. The solution space of A x = 0 is the null space of A, which has dimension 4 by the rank-nullity theorem.

Answer to Question 3:

No, the columns of A do not necessarily have to be linearly independent. The column space of A is the span of its columns, which has dimension p. However, the columns of A may be linearly dependent, which means that some columns can be expressed as linear combinations of the others.

Answer to Question 4:

To prove that H + K is a subspace of V, we need to show that it satisfies three conditions:

It contains the zero vector: 0 = 0 + 0 belongs to H + K, since it can be expressed as the sum of the zero vectors in H and K.

It is closed under vector addition: if w1 and w2 belong to H + K, then there exist h1 and k1 in H and K such that w1 = h1 + k1, and there exist h2 and k2 in H and K such that w2 = h2 + k2. Therefore, w1 + w2 = (h1 + h2) + (k1 + k2) belongs to H + K, since it can be expressed as the sum of vectors in H and K.

It is closed under scalar multiplication: if w belongs to H + K and c is a scalar, then there exist h and k in H and K such that w = h + k. Therefore, c w = c h + c k belongs to H + K, since it can be expressed as the sum of vectors in H and K.

We can expect 40 defective parts in a shipment of 1,000 parts.

We can use proportions to solve this problem.

The proportion of defective parts in the first shipment is:

16/400 = 0.04

This means that 4% of the parts in the first shipment are defective.

We can use this proportion to estimate the number of defective parts in a shipment of 1,000 parts.

If 4% of the parts are defective, we can set up the following proportion:

4/100 = x/1000

where x is the number of defective parts in the shipment of 1,000.

Simplifying the proportion, we get:

0.04 = x/1000

To solve for x, we can multiply both sides by 1000:

Let P be the initial value of the investment.

According to the problem, the investment grows to three times the initial value after t years. This can be expressed mathematically as:

P * e^(0.05t) = 3P

where e is the mathematical constant e (approximately 2.71828).

Simplifying this equation:

e^(0.05t) = 3

Taking the natural logarithm of both sides:

ln(e^(0.05t)) = ln(3)

0.05t = ln(3)

Dividing both sides by 0.05:

t = ln(3) / 0.05 ≈ 13.86

Rounding to the nearest hundredth, we get:

t ≈ 13.86 years.

Compound interest is a type of interest calculation where the interest earned on an investment is added to the principal (the initial amount invested), and then the total amount is used to calculate the interest earned for the next time period.
