For initial speeds of 30, 35 and 40 mph, displacement, velocity and acceleration can be computed.

The single mass - single energy absorber model of a 2021 Volkswagen ID.4 subjected to a frontal crash can be solved using a piecewise equation which will consist of three phases: loading, unloading and separation. The loading stiffness is 993.5 N/mm, the unloading stiffness is 18,027 N/mm and the vehicle mass is 2305 kg. The closed form solution for displacement, velocity and acceleration as a function of vehicle mass, initial velocity and energy absorber spring constants can be written as follows:

Displacement:

Loading phase:

$x_1(t) = \frac{F_{crash}}{m}t^2 + v_{in}t$

Unloading phase:

$x_2(t) = \frac{F_{crash}}{m}t^2 + v_{in}t - \frac{K_u}{m}t^2$

Separation phase:

$x_3(t) = \frac{F_{crash}}{m}t^2 + v_{in}t - \frac{K_u}{m}t^2 - \frac{K_u}{m}t^3$

Velocity:

Loading phase:

$v_1(t) = \frac{2F_{crash}}{m}t + v_{in}$

Unloading phase:

$v_2(t) = \frac{2F_{crash}}{m}t + v_{in} - \frac{2K_u}{m}t$

Separation phase:

$v_3(t) = \frac{2F_{crash}}{m}t + v_{in} - \frac{2K_u}{m}t - \frac{3K_u}{m}t^2$

Acceleration:

Loading phase:

$a_1(t) = \frac{2F_{crash}}{m}$

Unloading phase:

$a_2(t) = \frac{2F_{crash}}{m} - \frac{2K_u}{m}$

Separation phase:

$a_3(t) = \frac{2F_{crash}}{m} - \frac{2K_u}{m} - \frac{6K_u}{m}t$

For initial speeds of 30, 35 and 40 mph, displacement, velocity and acceleration can be computed and plotted versus time. The peak displacement, peak acceleration, rebound velocity, time of max displacement, and time of vehicle-barrier separation can be tabulated and compared. The results of the model at 35 mph can be validated graphically and by tabulating the parameters listed above.

The time taken to read 3 books is 8 weeks.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, Christian read 1/4 book every 2/3 week.

Time taken to read 1 complete book is

1 × 2/3 ÷ 1/4

= 2/3 ÷ 1/4

= 2/3 × 4/1 (To divide two fractions, keep the first fraction same and change division to multiplication and inverse the second fraction)

= 8/3

Now, time taken to read 3 complete is

= 8/3 ×3

= 8

Therefore, time taken to read 3 books is 8 weeks.

The angular speed of the pulley in rad/sec is 7.95 rad/sec, and the linear speed of the chain in cm/sec is 495.6 cm/sec.

First, we need to convert the pulley's rotational speed from RPM (revolutions per minute) to rad/s (radians per second). To do this, we can use the formula:

angular speed (in rad/s) = 2π × rotational speed (in RPM) / 60

Substituting the given values, we get:

angular speed (in rad/s) = 2π × 38 / 60 = 7.95 rad/s

Next, we can use the formula for linear speed of a point on the circumference of a circle:

linear speed = radius × angular speed

Substituting the values we have, we get:

linear speed = 26 cm × 7.95 rad/s = 206.7 cm/s

However, this is the linear speed of the pulley's circumference. Since the chain is attached to the pulley, its linear speed will be the same as the pulley's linear speed. Thus, the final answer for the linear speed of the chain is:

linear speed of chain = 206.7 cm/s × 2.4 = 495.6 cm/s

Here, 2.4 is the gear ratio of the chain to pulley.

A valid inference is a conclusion that is true about the subject based on the evidence or premises provided.

Mathematically, we can represent a valid inference using logical notation. In the example above, we can use the following notation:

Premise 1: All humans are mortal.

Premise 2: Samantha is a human.

Conclusion: Samantha is mortal.

We can use the logical connective "if-then" to represent a valid inference. In this case, we can say, "If all humans are mortal, and Samantha is a human, then Samantha is mortal." This statement is true based on the premises provided.

To determine the validity of an inference mathematically, we can use rules of logic such as the law of detachment or the law of syllogism. The law of detachment states that if we have a conditional statement, "If p, then q," and we know that p is true, then we can validly infer that q is also true.

The law of syllogism is another rule of logic that helps us determine the validity of an inference. This rule states that if we have two conditional statements, "If p, then q," and "If q, then r," we can infer that "If p, then r" is true.

If the surface area of a cube is 160 in2, then which best describes the length of an edge of the cube?

product of diagonal elements is 10 x -2 = -20.

To find the value of the determinant of the coefficient matrix, perform row operations to reduce it to an echelon form. First, multiply the first row by -3, the second row by 5, and the third row by 2. This yields the following matrix:

(-9)x + (0)y - 18z = -33

(25)x - 10y + 15z = 85

(4)x - (2)y - 14z = -6

Next, subtract the first row from the second row and the first row from the third row. This yields the following matrix:

(0)x + (10)y - (18)z = 52

(4)x - (2)y - (14)z = -6

Finally, subtract 4 times the second row from the third row. This yields the following matrix:

(0)x + (10)y - (18)z = 52

(0)x - (0)y - (2)z = -24

This matrix is in echelon form. The value of the determinant is simply the product of diagonal elements, which is 10 x -2 = -20.

Whole distance refers to the actual travel distance between the origin and destination locations of the item.

We can use the given scale to convert the distance between City A and City B to feet:

500 miles = 500 * 5280 feet = 2,640,000 feet

Since 1.6 feet represents this distance on the wall map, we have:

1.6 feet = 2,640,000 feet / x

where x is the actual distance represented by 1.6 feet on the map. Solving for x, we get:

x = 2,640,000 feet / 1.6 feet = 1,650,000 feet per foot

Therefore, the  total distance between City C and City D, which is 2.56 feet on the map, corresponds to:

Assuming the number of people who listen to the video increases by 45% each day, there would be approximately 24 new people who listen to the video on the 7th day after the initial 8 people.

According to the problem, the number of people listening to the video increases by 45% each day. Therefore, we can use the formula for compound interest to calculate the number of new people who listen to the video on the 7th day.

Let P be the initial number of people who listened to the video, which is 8.

Let r be the daily increase rate, which is 45% or 0.45 as a decimal.

Let n be the number of days, which is 7.

Then, the formula for compound interest is:

A = P(1 + r)^n

where A is the final number of people who listen to the video.

Plugging in the values, we get:

A = 8(1 + 0.45)^7

Let v1, v2, ..., vn be the vectors in S1 ∩ S2 and let a1, a2, ..., an be the coefficients in the linear combination a1v1 + a2v2 + ... + anvn = 0.

Since v1, v2, ..., vn are in S1 ∩ S2, they are also in S1 and S2. Therefore, the linear combination a1v1 + a2v2 + ... + anvn = 0 is also a linear combination of vectors in S1 and S2.

Expressions are commonly used in programming to perform calculations, manipulate data, and make decisions based on the results of evaluations.

To represent the parking fee using the function p(t), we need to consider the different rates depending on the number of hours parked. Here are the different cases we need to consider:

If t ≤ 2, the parking fee is P35.00

If 2 < t ≤ 12, the parking fee is P35.00 plus P15.00 for each hour (or fraction of it) after the first two hours. This can be represented by the equation:

p(t) = P35.00 + P15.00 × (t - 2)

If t > 12, the parking fee is a flat rate of P250.00.

We can combine these cases into a single function using a piecewise function. Here is the function p(t):

p(t) = {

P35.00 if t ≤ 2

P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12

P250.00 if t > 12

}

This function represents the parking fee in terms of the number of hours parked (t). To use it, simply substitute the number of hours parked into the function and calculate the resulting fee. For example, if you parked for 4 hours, the fee would be:

p(4) = P35.00 + P15.00 × (4 - 2) = P65.00

Therefore, p(t) = {

P35.00 if t ≤ 2

P35.00 + P15.00 × (t - 2) if 2 < t ≤ 12

To find the margin of error for a 90% confidence interval, we can use the formula:

Where z is the z-score for a 90% confidence level, p is the sample proportion, and n is the sample size.

In this case, the z-score for a 90% confidence level is 1.645, the sample proportion is 387/900 = 0.43, and the sample size is 900.

Plugging these values into the formula, we get:
