By solving a system of two simultaneous linear equation, it can be calculated that

There are 6 1p coin, 8 2p coin, 5 5p coin and 1 10p coins in the pot

What is simultaneous linear equation?

At first it is important to know about linear equation

Equation shows the equality between two algebraic expressions by connecting the two algebraic expressions by an equal to sign.

A one degree equation is known as linear equation.

Two or more linear equations, which can be solved together to obtain common solution are known as simultaneous linear equation.

Here a system of two simultaneous linear equation needs to be solved

Number of coins in a pot = 20

The coin are 1p, 2p,5p and 10p

Probability of 1p coin is \(\frac{3}{10}\)

So number of 1 p coins = \(\frac{3}{10} \times 20 = 6\)

Probability of 2p coin is \(\frac{2}{5}\)

So number of 2 p coins = \(\frac{2}{5} \times 20 = 8\)

Let the number of 5p coin be x and number of 10p coins be y

6 + 8 + x + y = 20

x + y  =20 - 14

x + y = 6 ..... (1)

Value of 6 1p coin = 6 \(\times\) 1 = 6p

Value of 8 2p coin = 8 \(\times\) 2 = 16p

Value of x 5p coin = x \(\times\) 5 = 5x p

Value of y 10p coin = y \(\times\) 10 = 10y p

Total value = 6 + 16 + 5x + 10y

                   = 5x  + 10y + 22

By the problem,

5x + 10y + 22 = 57

5(x + 2y) = 57 - 22

x + 2y = \(\frac{35}{5}\)

x + 2y = 7 ....... (2)

Subtracting (1) from (2)

y = 1

Putting the value of y in  (1)

x + 1 = 6

x = 6 - 1

x = 5

There are 6 1p coin, 8 2p coin, 5 5p coin and 1 10p coins in the pot.

Step-by-step explanation:

The relation 2 represents a function.

In order to determine which relation in the below table represents a function, we need to first understand what a function is.A function is a relationship in which each input value corresponds to exactly one output value.

To put it another way, each x-value has one and only one y-value. The most typical method to determine whether a relation is a function is to use the vertical line test.

The vertical line test is a way to determine if a relation is a function graphically. To test if a graph is a function, we draw a vertical line through each x-value on the graph. If a vertical line crosses the graph more than once, it is not a function.

If, on the other hand, the graph passes the vertical line test and no vertical line crosses the graph more than once, it is a function.Now let's look at the table below to determine which relation is a function.

We will first plot the x and y values of each relation on a coordinate system and then apply the vertical line test to each relation.

Relation 1: x | y0 | 10 | 11 | 22 | 23 | 34 | 35 | 4Relation 1 does not represent a function since we can draw a vertical line through x = 3 and the line will cross the graph more than once.

Relation 2: x | y2 | 33 | 34 | 45 | 46 | 57 | 5Relation 2 represents a function since we can draw a vertical line through each x-value on the graph and it will only cross the graph once.

Answer:

the difference between the highest and lowest values in a set of numbers.

Step-by-step explanation:

It's important to note that this calculation assumes that the interest rate remains constant and that no additional charges are added to the balance. In reality, the time it takes to pay off the balance could be longer due to these factors.

Assuming the minimum payment is calculated as a percentage of the balance, we can use the following formula to determine the time it would take to pay off the balance:

t = (-1/12) * log(1 - (r/12) * b/p) / log(1 + r/12)

where t is the time in years, r is the annual percentage rate (APR), b is the balance, and p is the minimum payment.

Substituting the given values, we get:

t = (-1/12) * log(1 - (0.14/12) * 1000/20) / log(1 + 0.14/12) = 94.5 months

It would take approximately 94.5 months or 7.9 years to pay off the balance with only minimum payments.

Step-by-step explanation:

it is complating squer method that used for solving x in a quadratic equetion . in this step you will add

(y/2)^2 if y is the cofitient of x .

The graph of n(x) is a reflection, 1 unit up, and a translation 2 units to the right of the graph of f(x).

The function f(x) = ∛x is the cube root function, which has a basic graph passing through the origin and increasing as x increases.

When we consider the function n(x) = ∛(-8x) - 1, we notice that the negative sign in front of the argument of the cube root function implies a reflection about the y-axis.

This means that the graph of n(x) will be a mirror image of the graph of f(x) with respect to the y-axis.

Next, the -1 outside the cube root function implies a vertical shift of 1 unit downwards.

Therefore, the graph of n(x) will be shifted 1 unit down from the graph of f(x).

Finally, the factor of -8 in front of x implies a horizontal stretch by a factor of 1/8.

This means that the graph of n(x) will be compressed horizontally by a factor of 1/8 compared to the graph of f(x).

Overall, the graph of n(x) is a reflection, 1 unit up, and a translation 2 units to the right of the graph of f(x).

Answer:

Step-by-step explanation:

Let the height of the lantern = x.

Set the ratios:

Ratio of the lantern & shadow: (x/72)

Ratio of the man & shadow: (6/18)

*Note: Remember to consistently set the ratio. For me, I set it as the thing/man over the shadow. You can do the opposite, but both must be the same either (thing/person)/shadow, or shadow/(thing/person).

Set the ratios equal to each other, and cross multiply

(x/72) = (6/18)

(18x) = (6 * 72)

18x = 432

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 18 from both sides:

(18x)/18 = (432)/18

x = 432/18

x = 24

24 ft is the height of the lightpost.

we have

x tetras

3 goldfish

5 platies.

the total number of fishh in the bowl is x + 3 + 5

The probability of removing a gold fish is equal to the number of gold fish divided by the total number of fish, this is:

p = 3/(x + 3 + 5) = 1/3

3 = (1/3)(x + 3 + 5) = x/3 + 1 + 5/3

9 = x + 3 + 5

x = 9 - 8 = 1

then wemust have that x = 1

because 1 + 3 + 5 = 9

and 3/9 = 1/3

Let daughter be x years old. Then, Shyam is (x + 28) years old.

So,

x(x + 28) = 204

=> x² + 28x = 204

=> x² + 28x - 204 = 0

=> x² - 6x + 34x - 204 = 0

=> x(x-6) + 34(x-6)

=> (x - 6) (x + 34) = 0

=> x - 6 = 0 or x + 34 = 0

=> x = 6 or x = -34

The equation to determine the number of hours it will take to fill the pool, given the current level of the pool, the rate at which the pool is being filled, and the pool's capacity can be found using the following steps.

To write an equation that can be used to find the number of hours it will take to fill the pool from its current level, we need to use the following information:

The pool's capacity: 43,000 gallons

The current level of the pool: 20,000 gallons

The rate of filling the pool: 130 gallons per minute

We can start by using the formula:

time = (amount needed to fill)/(rate of filling)

The amount needed to fill the pool is the difference between the pool's capacity and the current level of the pool.

amount needed to fill = 43,000 - 20,000 = 23,000 gallons

Now we can substitute this value in the formula above:

time = (23,000 gallons)/(130 gallons/minute)

To convert the time to hours, we divide the time in minutes by 60

time = (23,000 gallons)/(130 gallons/minute) × (1 hour/60 minutes)

So, the equation that can be used to find h, the number of hours it will take to fill the pool from its current level is:

h = (23,000 gallons) / (130 gallons/minute) × (1 hour/60 minutes)

Note that this equation is not simplified, you can simplify it by canceling out common factors, you'll get:

h = (23000 / 130) × (1/60)

This equation can be used to find the number of hours it will take to fill the pool, given the current level of the pool, the rate at which the pool is being filled, and the pool's capacity.

The term "arc" is used to describe units of measure for angular distance because it refers to the length of an arc on a circle.

Angular distance is the measure of the separation between two points on a circle or an arc. The term "arc" is used to describe this measure because it refers to the length of the arc connecting the two points on the circle.

This length is a fraction of the circumference of the circle and is proportional to the angle between the two points. The use of the term "arc" in this context is a nod to the geometric origins of angular measurement, which is based on the properties of circles and their angles.

The most common units of angular measurement are degrees, minutes, and seconds, which are all based on the division of a circle into 360 equal parts (degrees) and further subdivisions (minutes and seconds).

Other units of angular measurement, such as radians and gradians, are also based on the properties of circles and their angles.

The Laplace transform of the function f(t) = e^(3t) - 18h(t-6) can be found using the properties of the Laplace transform and the definition of the unit step function.

To find the Laplace transform, we split the function into two parts. The first part is e^(3t), which has a Laplace transform of 1/(s-3) due to the Laplace transform property e^(at) ⇔ 1/(s-a). The second part is -18h(t-6), where h(t-6) is the unit step function shifted by 6 units to the right. The Laplace transform of the unit step function h(t-a) is 1/s multiplied by e^(-as), which gives us 1/s * e^(-6s) in this case.

Combining the two parts, the Laplace transform of f(t) is given by F(s) = 1/(s-3) - 18/(s) * e^(-6s).

In summary, the Laplace transform of f(t) = e^(3t) - 18h(t-6) is F(s) = 1/(s-3) - 18/(s) * e^(-6s), where F(s) is the Laplace transform of f(t) with respect to the variable s.

The time complexity of finding a source in a directed graph or determining such a source does not exist if the graph is represented by its adjacency matrix is V².

If a directed graph is represented by an adjacency matrix, the following approach may be used to either discover a source inside the network or establish that there isn't one:

This approach has an O(V²) time complexity, where V is the number of graph vertices. This is due to the fact that it takes O(V²) time to traverse the whole adjacency matrix in order to determine each vertex's in-degree. The next step requires traversing the inDegree array in O(V) time in order to discover a vertex with in-degree 0. In the worst scenario, it takes O(V²) time to determine if there is a path connecting this vertex to every other vertex.
