The coordinates of the remaining vertices exists (2√(13),1) and (-2, 4√(13)).

A group of values that exhibit precise positioning The first number on a graph represents the distance along, while the second number represents the distance up or down.

To find the coordinates of the remaining vertices of square ABCD, we can use the information given about diagonal AC and the properties of a square. Since a square has equal side lengths and right angles, we know that the distance between opposite vertices on a diagonal must be equal to the side length of the square.

Given the coordinates of vertex A and C, we can use the distance formula to find the length of AC :

Let the equation be Distance [tex]$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$[/tex] substitute the values in the above equation, we get

[tex]$\mathrm{AC}=\sqrt{\left((2-(-2))^2+(4-1)^2\right)}$$[/tex]

simplifying the equation, we get

[tex]$A C=\sqrt{ }(4+9)=\sqrt{ }(13)$$[/tex]

We can utilize the knowledge of the square's side length to determine the locations of the remaining vertices. Vertex B is known to have the same y-coordinate as vertex A, while vertex C is two units to the left in terms of the x-coordinate. Therefore, the coordinates of vertex B exists (-2 + 2√(13), 1).

Similar to vertex A, vertex D is known to have an identical x-coordinate, but its y-coordinate is four units below vertex C. Therefore, the coordinates of vertex D exists (-2, 4√(13))

Therefore, the coordinates of the remaining vertices exists (2√(13),1) and (-2, 4√(13)) respectively.

The complete question is:

Square ABCD has a diagonal AC with vertices A(-2, 1) and C(2, 4). Find the coordinates of the remaining vertices. Express your answers as decimals, if necessary.

Answer:

To verify that [n+3]! / n! = (n+1), we can use the definition of factorial:

[n+3]! = (n+3) * (n+2) * (n+1) * n!

And we can cancel out n! from both sides of the equation:

(n+3) * (n+2) * (n+1) = n+1

Which is true, and thus [n+3]! / n! = (n+1) holds true.

Another way to verify this is by simplifying the RHS and LHS

(n+1) = (n+1)

And the LHS,

(n+3)! = (n+3)(n+2)(n+1)n! = (n+1)(n+2)(n+3)n! = (n+1)(n+2)(n+3)!/n!

which is also equal to (n+1)

So, [n+3]! / n! = (n+1) is true.

Answer: The value of x is 0 and y is -5 using the elimination method.

Step-by-step explanation: To use the elimination method, we will remove one variable and find the value of the other one. Rewriting the equation -

-2y + 5x = 10 : equation 1

-3y + 4x = 15 : equation 2

Multiplying equation 1 with 4 and equation 2 with 5

-8y + 20x = 40 : equation 3

-15y + 20x = 75 : equation 4

Subtracting equation 3 from equation 4 to eliminate variable y

-7y = 35

y = - 35/7

y = -5

Keep the value of y in Equation 1 to find the value of x

-2(-5) + 5x = 10

10 + 5x = 10

5x = 10 - 10 5x = 0

x = 0

So, the value of x is 0 and y is -5.

Answer:5=y

Step-by-step explanation:

10 − 5x=−2y

15 − 4x =−3y

• (10 − 5x=−2y)4

         (40 - 20x=−8y)

          15 − 4x =−3y

         (15 − 4x =−3y)5

El número de este problema es 72, y la suma de sus cifras da 9.

En este problema tenemos un numero de dos cifras, que podemos escribir como:

a*10 + b

Donde a y b son numeros enteros entre 0 y 9, y son las cifras de nuestro número.

Sabemos que si a este número le aumentamos 3 veces la cifra de decenas, resulta en 93, entonces podemos escribir:

a*10 + b + 3*a = 93

The speed of the boat against the current is (13+x)mph and with the current is (13-x) mph.

If boat goes along the stream flow (downstream), then the speed of boat will be increased as stream will help boat go faster. In contrast, the upstream flow of boat will be slower than its speed in normal flow due to stream resistance.

Speed of boat with the current = Speed of boat + Speed of current

Speed of boat against the current = Speed of boat - Speed of current

Given that the speed of a boat in still water is 13 mph. Also, the speed of the water current is x mph. Therefore, the speeds in the given cases can be written as,

Gradient-based optimization: This method is commonly used for more complex models, such as deep neural networks. The goal is to find the set of model parameters that minimizes a loss function.

Generally, There are a variety of ways to estimate mathematical models, depending on the type of model and the available data. Some common methods include:

Least squares: This method is commonly used for linear regression models, where the goal is to find the line of best fit through a set of data points. The least squares method finds the line that minimizes the sum of the squared differences between the predicted values and the actual values.

Maximum likelihood: This method is commonly used for probabilistic models, such as those used in statistics and machine learning. The goal is to find the set of model parameters that maximizes the likelihood of the observed data.

Bayesian inference: This method is similar to maximum likelihood, but it also incorporates prior knowledge or beliefs about the model parameters into the estimation process. This can be done by specifying a prior distribution over the parameters, which is then updated based on the observed data to give a posterior distribution.

These are just a few examples, and there are many other methods available depending on the type of model and the data available.

Answer: To find the coordinates of the remaining vertices of square ABCD, we can use the information we have been given about the diagonal AC and its vertices. The diagonal AC has been given as having the vertices A(-4, -1) and C(2, 5). Since a square has right angles, we know that the other two vertices of the square must form a right angle with the diagonal AC.

To find the coordinates of vertex B, we know that it must have the same y-coordinate as vertex A, but a different x-coordinate. Since the x-coordinate of vertex A is -4, we can deduce that the x-coordinate of vertex B must be the same as the x-coordinate of vertex C, which is 2. Therefore, the coordinates of vertex B are (2, -1).

To find the coordinates of vertex D, we know that it must have the same x-coordinate as vertex A, but a different y-coordinate. Since the y-coordinate of vertex A is -1, we can deduce that the y-coordinate of vertex D must be the same as the y-coordinate of vertex C, which is 5. Therefore, the coordinates of vertex D are (-4, 5).

In summary, the coordinates of the remaining vertices of square ABCD are B(2, -1) and D(-4, 5)

Step-by-step explanation:

A function assigns the value of each element of one set to the other specific element of another set. The value of the function when the value of x is -4 is 92.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

Given that F(x)=3x²-10x+4, therefore, the value of the function can be calculated by substituting the value of x as -4.

Therefore, the value of the function when the value of x is -4  can be calculated as shown below,

F(x) = 3x² - 10x + 4

F(-4) = 3(-4)² - 10(-4) + 4

= 3(16)  + 40 + 4

= 48 + 40 + 4

= 92

Hence, the value of the function when the value of x is -4 is 92.

The rule for the exponential function is y=42(1/2)^x

A exponential decay is a function that, as the name implies, decays exponentially. So it decays fast at the beginning and slower as the value of the variable increases.

Here,

general form of exponential function is y=a(b)^x

a= y-intercept ,  b = multiplier

The initial y value 42 is multiplied by 1/2, we get next y value 21 as given in the graph, So, b = 1/2

y=a(1/2)^x

consider (x,y)=( 0,42)

=> x=0 and y=42

So 42=a(1/2)^0

=> 42=a

Thus, the rule for the function is y=42(1/2)^x

Answer: Circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π is a constant.

We know that the diameter is twice the radius (d = 2r).

So when we increase the circumference of the circle from 12π cm to 18π cm, we are increasing the radius from r to r'.

To find the increase in diameter, we can use the formula for the diameter, and subtract the original diameter from the new diameter.

d' = 2r' and d = 2r

d' - d = 2r' - 2r

We know that the relationship between circumference and radius is C = 2πr.

So we can write:

12π = 2πr and 18π = 2πr'

r = 6/π and r' = 9/π

then

d' - d = 2r' - 2r = 2(9/π) - 2(6/π) = 18/π - 12/π = 6/π

Therefore, the diameter must increase by 6/π cm in order to increase the circumference of the circle from 12π cm to 18π cm.

Answer:

b) The bond Sandy purchased has a face value of $2500 and a coupon rate of 7%. The coupon rate is the interest rate paid on the bond, which is typically paid semiannually. To find how much interest Sandy will receive semiannually, we can use the formula:

Interest = Face value x Coupon rate / 2

Interest = $2500 x 7% / 2 = $87.50

So Sandy will receive $87.50 in interest semiannually from the bond.

c) The fund Sandy invested in is expected to grow by 3.5% per year. To find how long it will take for the fund to be worth $10,000, we can use the formula:

Future value = Present value x (1 + Interest rate)^Years

We can solve for Years by dividing both sides of the equation by the present value and taking the natural logarithm of both sides:

Years = ln(Future value/Present value) / ln(1 + Interest rate)

Years = ln(10000/5000) / ln(1.035)

Years = 7.19

Therefore, the fund will take about 7.19 years to be worth $10,000.

d) Sandy's gross annual income is $51,350. She is paid biweekly, and 5% of her paycheck is deducted for her 403(b). Her employer matches her deduction, up to 4%. To find how much is deposited into Sandy's 403(b) each payday, we can use the following formula:

Contribution = (Gross pay x Contribution rate) + (Employer match x Employee contribution)

Gross pay = $51,350/26 (for bi-weekly paycheck) = $1977.50

Contribution = ($1977.50 x 5%) + ($1977.50 x 5% x 4%) = $98.87

So, $98.87 is deposited into Sandy's 403(b) each payday.
