what is the difference between a line spectrum and a continuous spectrum? provide an example of each.

Answer:

$31.56

Step-by-step explanation:

We know

Skateboard cost: $37.50

20% off, so 80% left = 0.8

5.2 tax + 100% = 105.2% = 1.052

So, we have the equation

37.50 (0.8) (1.052) = $31.56

So, Petra will pay $31.56 for the skateboard deck in all!

When measuring height or distance, it is important to consider different perspectives when the measurement is influenced by factors such as angles, elevation, or relative positions, which can affect the accuracy of the measurement.

Different perspectives should be considered when measuring height or distance in situations where there are variables that can impact the measurement. These variables may include the angle from which the measurement is taken, the elevation or relative position of the observer, or other factors that can introduce errors or inconsistencies.For example, when measuring the height of a tall building, if the observer is at a significant distance or at a different angle than the base of the building, it can lead to inaccurate measurements. In such cases, it is important to consider different perspectives, possibly by using tools like surveying instruments or multiple observers at different locations, to ensure a more accurate measurement. Similarly, when measuring distances across uneven or hilly terrain, considering different perspectives becomes crucial. The line of sight between two points may be obstructed or require adjustments to account for the elevation changes

When two tables have a one-to-many relationship, you typically need to add a foreign key to the table on the "many" side to link the records to the corresponding record in the "one" table.

In a one-to-many relationship, the table on the "one" side is usually the primary key table, and the table on the "many" side is usually the foreign key table. The foreign key is used to link the records in the "many" table to the corresponding record in the "one" table. This is done by adding a column to the "many" table that contains the primary key value from the "one" table.

When designing a database, it is important to establish relationships between tables to ensure data integrity and avoid redundant data. In a one-to-many relationship, one record in the primary key table can be associated with many records in the foreign key table. To establish a one-to-many relationship, you need to create a primary key in the "one" table and a foreign key in the "many" table. The foreign key is a column that contains the primary key value from the "one" table. For example, if you have a "customers" table and an "orders" table, the "customers" table would be the primary key table and the "orders" table would be the foreign key table. Each record in the "orders" table would have a foreign key column that contains the customer ID from the "customers" table.

Answer:

x = -2, y = 3

Step-by-step explanation:

Given equations are,

4x + 5y = 7 ---------(1)

3x - 2y = -12 ----------(2)

Multiply equation (1) by 3

12x + 15y = 21 ------(3)

Multiply equation (2) by (-4)

-12x + 8y = 48 --------(4)

Now add equations (3) and (4),

(12x + 15y) + (-12x + 8y) = 21 + 48

(12x - 12x) + (15y + 8y) = 69

23y = 69

y = 3

From equation (2),

3x - 2(3) = -12

3x - 6 = -12

3x = 6 - 12

x = -2

Therefore, x = -2 and y = 3 will be the answer.

Mariam will have purchased 3.5 pounds of fruit if she purchases 3 pounds of apples and 0.5 pounds of strawberries.

Mariam will purchase a total of (x + y) pounds of fruit if she purchases x pounds of strawberries and y pounds of apples.

The arithmetic operations were used to arrive at the answer.

The four basic operations—often referred to as "arithmetic operations"—are thought to be able to describe all real numbers. Divide, multiply, add, and subtract are the four mathematical operations that result in the quotient, product, sum, and difference.

We are given that Mariam buys 0.5 pounds of strawberries and 3 pounds of apples.

So, the total pounds of fruit bought = 0.5 + 3 = 3.5

Similarly, if she buys x pounds of strawberries and y pounds of apples, then the total amount of pound of fruits  = (x + y)

Hence, the required solution has been obtained.

We may deduce from the average speed that the aircraft must have at least once during the flight attained a speed of 478.72or higher.

This implies that the aircraft must have surpassed 100 mph once while descending to its average speed following takeoff.

So,

We can write,

The speed of the aircraft decreased throughout the arrival from its usual speed to 100 miles per hour before returning to zero at the destination.

Based on the given conditions,

Total distance of the flight = 2250 miles

Flight takeoff time = 2:00 pm

Arrival time of the flight = 7:40 pm

So,

The total time taken by the flight to cover 2250 = 4 hours 40 minutes

The total time is taken by the flight to cover 2250 = 4.7 hours

Then,

The average speed of the plane =Total distance/ total time

We can substitute values,

total distance = 2250,

total time = 4.7 hours

The average speed of the plane = 2250÷4.7

The average speed of the plane  is 478.72 miles per hour

From the average speed we can analyze that the plane must have reached the speed of 478.72 or more at least once during the journey this also concludes that the plane must have reached the speed of 100 miles per hour once while reaching to the average speed after the takeoff.

Hence,

During the arrival, the speed of the plane also reached went from the average speed to 100 miles per hour and then zero at the arrival destination

Therefore,

There were at least two times during the flight when the speed of the plane was 100 miles per hour.

Given that three charges (-25 nC, 79.1nC, and −55.9nC) are placed at three of the four corners of a square with sides of length 22.2 cm. We need to determine the value of the electric potential (in V) at the empty comer if the positive charge is placed in the opposite corner.

The formula for the electric potential at a point in space is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) + ….. ]where;k = Coulomb's constant (8.99 × 10^9 Nm²/C²)q1, q2, q3,…. are the charges at the cornersr1, r2, r3,…. are the distances from the corner to the point whose potential is being calculated Now we can calculate the electric potential at the empty corner as follows;The three charges can be represented as shown below:Charges at corners of a square

The distance from any corner to the opposite corner (where the positive charge is placed) is given by d = √[ (22.2 cm)² + (22.2 cm)² ] = 31.4 cmTherefore, the electric potential at the empty corner is given by;V = k [ (q1 / r1) + (q2 / r2) + (q3 / r3) ]Here, q1 = -25 nC, q2 = -55.9 nC, q3 = 79.1 nC, r1 = r2 = r3 = d = 31.4 cm = 0.314 mPlugging in the values we get;V = 8.99 × 10^9 [ (-25 × 10^-9 / 0.314) + (-55.9 × 10^-9 / 0.314) + (79.1 × 10^-9 / 0.314) ]= 8.99 × 10^9 [ -0.0795 - 0.1783 + 0.252 ]= 8.99 × 10^9 × 0.0052= 46.8 VTherefore, the value of the electric potential at the empty comer if the positive charge is placed in the opposite comer is 46.8 V.

Step-by-step explanation:

To show that oc is an irregular singular point of the modified Bessel equation, we can analyze the coefficients of the equation.

The modified Bessel equation is given by:

2²y + - (1²+1²) y = 0

The coefficient of the y'' term is 2², which is nonzero, indicating that oc is a singular point.

Now, let's prove the leading behavior of the modified Bessel function using the power series expansion.

The power series expansion of the modified Bessel function is given by:

I(x) = ∑ ((x/2)^(2n) / (n!(n!)(2^2n)))

To find the leading behavior, we need to consider the term with the highest power of x, which corresponds to n → +∞.

As n approaches infinity, the term (x/2)^(2n) becomes dominant, and other terms become negligible. Therefore, we can approximate the leading behavior as:

I(x) ~ (x/2)^∞

This approximation indicates that the modified Bessel function grows exponentially as x increases.

Based on this result, we can make an educated guess about the asymptotic expression for the Hankel function (cylindrical). The Hankel function is defined as the linear combination of the modified Bessel functions of the first kind (I(x)) and second kind (K(x)).

H(x) ~ C1 * I(x) + C2 * K(x)

The asymptotic expression for the Hankel function is expected to have a similar form to the modified Bessel function, with exponential growth as x increases.

Please note that the above explanations provide an overview of the concepts and a rough understanding of the behavior. For a more rigorous and detailed analysis, further mathematical analysis and proofs may be required.
