The average rate of change of the inductor's energy between t = 0.0 to t = 1 .0 is 6
The term circuit in defined as an inductor and a resistor is called an RL-circuit here the inductor resists any current change in the circuit and the resistor dissipates energy, then the resulting in the exponential decay of current if no current or voltage source is present.
Here we need to calculate the average rate of change for the inductor's energy,
Here we know that the values of t1 = 0, and t2 = 1
Similarly, here we know the value of flow of current as f(t1) = 12 and f(t2) = 18.
Now, the average rate of change is calculated as
=> [18 - 12]/1 - 0
When we simplify the expression, then we get,
=> 6/1
=> 6

How to find duplicate numbers in an array if it contains multiple duplicates?
The pigeonhole principle can be used to demonstrate that there must be at least one duplicate in the set nums. Each possible number that can appear in nums is a "pigeonhole" in this context, and each number within nums is a "pigeon."
Method or evidence to confirm that Nums must contain multiple duplicate number: Simple Strategy: Utilizing nested loops, it is intended to determine whether or not each element appears in the array more than once for each element.
Put it in a hash-map if it is there. Otherwise, keep looking at the other components.Duplicate data might be valuable in some situations, but it can also make your data more difficult to analyze.Find and highlight duplicate data using conditional formatting.You can then examine the duplicates and determine whether you wish to eliminate them.The duplicate data will be permanently removed when you use the Remove Duplicates functionality. It's a good practice to copy the original data to another worksheet before deleting the duplicates so you don't unintentionally lose any data.Choose the range of cells where the duplicate values should be eliminated.To remove duplicates, select Data, and then Check or uncheck the columns you want to have the duplicates removed from under Columns.Learn more about duplicate number Visit: brainly.com/question/15323323

What is a Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Given data ,
Let the triangle be represented as ΔABC
Now , the value of the sides of the triangle is
AB = 54 m
BC = 78 m
AC = 90 m
Now , for the triangle to be right angle triangle , it should satisfy the Pythagoras Theorem
So , For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substitute the values in the equation , we get
AC² = AB² + BC²
90² = 54² + 78²
8100 = 2916 + 6084
8100 ≠ 9000
Therefore , the triangle ΔABC is not a right angle triangle

⭐ What is the multiplicative rate?
The multiplicative rate is the number each consecutive y-value gets multiplied by.The multiplicative rate can only be found in exponential functions.To find the multiplicative rate of this exponential function, we need to make an equation to see what each y-value gets multiplied by to get the next y-value.
I am picking the y-values 2 and 2/5, but you can choose any two consecutive y-values.
Equation (let x= the multiplicative rate of change):
[tex]2x = \frac{2}{5}[/tex]
Solve for x:

how do I convert 5 rows of ribbons to inches
You may use the expression to convert the length of 5 rows of ribbons to inches: length = 5w + (5 - 1)s inches, where w is the width of the ribbons and s is the spacing between the rows.
To convert 5 rows of ribbons to inches, you need to know the width of the ribbons and the spacing between the rows.
Let's say the width of the ribbons is w inches, and the spacing between the rows is s inches. In this case, the total length of the ribbons in 5 rows would be 5w + 4s inches, since there are 5 ribbons and 4 spaces between them.
For example, if the width of the ribbons is 0.5 inches and the spacing between the rows is 0.1 inches, the total length of the ribbons in 5 rows would be :5 × 0.5 inches + 4 × 0.1 inches = 2.5 inches + 0.4 inches = 2.9 inches.

Speed of object = 40 feet per second
What is speed and its formula?Speed is calculated as follows: speed = distance * time. Knowing the units for distance and time is necessary to calculate the units for speed. The units will be in metres per second (m/s) in this example since the distance is measured in metres (m) and the time is measured in seconds (s).Speed is what it means. the speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar number.Based on the distance travelled in a certain amount of time. These automobiles can travel at speeds of more than 150 kilometres per hour (km/h). Meters per second (m/s) is the fundamental unit of speed in the metric system.Given data :

For a sample population of size, n =5, sx = 20 and sx² = 120, the sum of squared deviation is 40.
Therefore, the answer is 40.
Given a sample population of 5 scores, that is n = 5.
sx = ∑x = 20
sx² = ∑x² = 120
Thus mean can be calculated by
mean, x⁻ = ∑x/ n
x⁻ = 20/ 5
x⁻ = 4
The sum of squared deviations
ss = ∑( x - x⁻)²
ss = ∑( x² -2×x×x⁻ + x⁻²)
ss = ∑x² -2×x⁻×∑x + ∑x⁻²

If d/dx (g(x)) = 0
then d/dx (g(x)sin(x)) = ?
Answer:
Step-by-step explanation:
If the derivative of g(x) with respect to x (denoted d/dx g(x)) is equal to 0, then the derivative of the product g(x)sin(x) with respect to x can be found using the product rule for derivatives.
The product rule states that if f(x) and g(x) are two functions, then the derivative of the product f(x)g(x) with respect to x is given by:
d/dx (f(x)g(x)) = f(x) * d/dx g(x) + g(x) * d/dx f(x)
In our case, f(x) is g(x) and g(x) is sin(x). Substituting these values into the equation above, we get:
d/dx (g(x)sin(x)) = g(x) * d/dx sin(x) + sin(x) * d/dx g(x)
Since the derivative of sin(x) with respect to x is cos(x) and the derivative of g(x) with respect to x is 0, we can simplify this expression to:
d/dx (g(x)sin(x)) = 0 * cos(x) + sin(x) * 0
Which simplifies to:
d/dx (g(x)sin(x)) = 0
Therefore, if the derivative of g(x) with respect to x is equal to 0, then the derivative of the product g(x)sin(x) with respect to x is also equal to 0.

Harry's soccer team is trying to raise $2,520 to travel to a tournament in florida, so they decided to host a pancake breakfast. Each person must pay $15 for the breakfast. How many people need to attend their breakfast in order to raise $2520?.
Harry's soccer team needs 168 people to attend their pancake breakfast in order to raise $2,520.
To find the number of people that need to attend the pancake breakfast, we can set up the following equation:
Number of People x Cost per Person = Total Cost
We know that the total cost is $2,520 and the cost per person is $15, so we can substitute those values into the equation:
Number of People x $15 = $2,520
We can solve for the number of people by dividing both sides of the equation by $15:
Number of People = $2,520 / $15
This gives us the number of people that need to attend the pancake breakfast in order to raise the desired amount of money. In this case, the number of people is 168.
Therefore, Harry's soccer team needs 168 people to attend their pancake breakfast in order to raise $2,520.
