Answer:

Thus, the equation of line for point (-1, 2)  is y = x + 3.

Step-by-step explanation:

Answer:

The equation of the line is y = x + 3.

Step-by-step explanation:

A line that is parallel to y=x+4 and passes through the point (-1,2) will have the same slope as y=x+4. The slope of y=x+4 is 1, so the equation of the line will be in the form y = mx + b, where m=1. To find b, we can plug in x = -1 and y = 2 into the equation and solve for b.

y = mx + b

y = 1 * -1 + b

y = -1 + b

b = y + 1

b = 2 + 1

b = 3

The area of a circular pool having radius 16 units is 804.24772 units².

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

The circular pool has a radius of 16 units.

The formula for the area of circle is πr².

Here, r represents the radius of the circle.

Area = πr²

Substitute the values into the equation -

Area = π(16)²

Find the square of 16 -

Area = π × 256

Use the arithmetic operation of multiplication -

Area = 256 π

The value of π = 3.14159265359

Area = 256 × 3.14159265359

Use the arithmetic operation of multiplication -

Area = 804.24772

Therefore, the area is obtained as 804.24772 units².

Answer:

FV= $34,222.33

Step-by-step explanation:

First, we need to calculate the weekly interest rate:

Weekly interest rate= 0.0289/52= 0.00056

To calculate the future value (FV), we need to use the following formula:

FV= {A*[(1+i)^n-1]}/i

A= weekly deposit

n= 15*52= 780

A= $35

FV= {35*[(1.00056^780) - 1]} / 0.00056

FV= $34,222.33

Answer: -1

Step-by-step explanation:

    We will find the answer to this question by isolating the x variable.

    Given:

2(3x – 1) ≥ 4x – 6

    Distribute the 2 with multiplication:

6x – 2 ≥ 4x – 6

    Add 2 to both sides of the equation, and subtract 4x from both sides of the equation:

2x ≥ – 4

    Divide both sides of the equation by 2:

x ≥ -2

    The only value given that is greater than or equal to -2 is -1, leaving us with an answer of;

The elapsed time between 12:15 A.M. and 2:15 P.M. is 14 hours.

What is elapsed time?

Elapsed time is the amount of time that has passed between a starting point and an ending point. It is the difference between the ending time and the starting time. Elapsed time can be calculated for any duration of time, from seconds to hours, days, or even years.

To find the elapsed time between 12:15 A.M. and 2:15 P.M., we need to calculate the number of hours and minutes that have passed.

First, we need to convert the time to a 24-hour clock format.

12:15 A.M. can be represented as 00:15 and 2:15 P.M. can be represented as 14:15.

We can then subtract the start time from the end time to find the elapsed time:

14:15 - 00:15 = 14 hours

Therefore, the elapsed time between 12:15 A.M. and 2:15 P.M. is 14 hours.

While Piaget, Vygotsky, and Bruner have different perspectives on how learning occurs, they all emphasize the active role of the learner in constructing knowledge and the importance of social interaction and cultural influences in the learning process.

Here's a three-column table evaluating how learning takes place according to Piaget, Vygotsky, and Bruner:

Theorist Approach to Learning Key Concepts

Piaget Constructivism 1. Schema: Individuals actively construct their knowledge through assimilation and accommodation, organizing information into mental structures called schemas. 2. Stages of Development: Learning occurs through cognitive development stages, from sensorimotor to formal operational, where individuals progressively acquire more complex mental abilities. 3. Active Exploration: Children learn best through hands-on exploration and interactions with the physical world.

Vygotsky Sociocultural Theory 1. Zone of Proximal Development (ZPD): Learning takes place within the gap between a learner's actual developmental level and their potential level with guidance from a more knowledgeable other. 2. Social Interaction: Learning is facilitated through social interactions with peers and adults, such as cooperative learning and scaffolding. 3. Cultural Tools: The use of language, symbols, and cultural artifacts plays a central role in cognitive development and learning.

Bruner Constructivism 1. Scaffolding: Instruction should provide support and guidance tailored to the learner's current abilities to help them progress to higher levels of understanding. 2. Discovery Learning: Learners construct knowledge by actively exploring and discovering concepts and relationships on their own. 3. Spiral Curriculum: Learning is organized in a spiral manner, revisiting key concepts and building upon previous knowledge in a progressive and interconnected way.

Answer:

17.7 inches.

Step-by-step explanation:

The equation of the line of best fit is y = - 0.368x + 18.483 .......... (1)

Based on the line of best fit, we have to approximate how many inches of snowfall during the month of January when the average temperature is 2°F.

So, here, x = 2 and we have to calculate y using the equation (1).

So, y = - 0.368 × 2 + 18.483 = 17.747 ≈ 17.7 inches. (Answer)

The solutions to the equations are;

y = 2

x = 7

From the information given, we have that the simultanoeus equation;

x² + y²=53

x²-y²= 45

Make 'x' the subject from equation 1, we have that;

x =√ 53 - y²

Substitute the values, we have;

(√53 - y²)² - y² = 45

find the square root, we have;

53 - y² - y² = 45

collect the like terms, we have;

-2y² = 45 - 53

subtract the values

-2y² = -8

y² = 4

y = 2

Substitute the value, we have;

x = √53 - (2)²

The matrix's inverse is \(\left[\begin{array}{ccc}1&2&3\\3&4&6\\7&8&9\end{array}\right]\)

To find the inverse of a matrix A, you can use the following formula:

A⁻¹ = (1/det(A)) * adj(A)

Where det(A) is the determinant of matrix A, and adj(A) is the adjugate of matrix A. The adjugate of a matrix is the transpose of the cofactor matrix of A.

Once you have found the inverse of matrix A, you can use it to solve a system of linear equations. To express a system of linear equations in matrix form, you can use the following notation:

Ax = b

Where A is the coefficient matrix, x is the vector of unknowns, and b is the vector of constants. In this case, the system of linear equations is:

x + 2y + 3z = 1

3x + 4y + 6z = 2

7x + 8y + 9z = 3

You can write this system in matrix form as:

A =\(\left[\begin{array}{ccc}1&2&3\\3&4&6\\7&8&9\end{array}\right]\)

x = [x; y; z]

b = [1; 2; 3]

Ax = b

Now, to solve for x, you can use the formula:

x = A⁻¹ * b

Where A⁻¹ is the inverse of matrix A, and b is the vector of constants. Once you have found x, you can substitute its values into the original system of linear equations to check your answer.

Answer:The scale factor= 1 : 41.14

Step-by-step explanation:

I did research on it

The angles in the parallel lines are as follows;

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, linear angles, vertically opposite angles etc.

Therefore, let's find the angles m∠1 and m∠2.

Hence,

138 + m∠1 = 180(angles on a straight line)

The sum of angles on a straight line is 180 degrees.

m∠1 = 180 - 138

m∠1 = 42 degrees

Therefore,

m∠1 =  m∠2 (alternate exterior angles)

Alternate exterior angles are the pair of angles that are formed on th outer side of the parallel lines but on the opposite side of the transversal.

Alternate exterior angles are congruent.

Therefore,

m∠1 =  m∠2 = 42 degrees.

distance traveled in 9 hours = 3x

Therefore, the car will travel 3 times the distance it travels in 3 hours when it travels for 9 hours.

The unit rate of computers per day using the graph is that 12 computers are made per day.

The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.

To obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x

So, it is given by:

\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)

\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)

\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)

\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)

\(\bold{Slope = 12}\)

Yes,  This is established by the Rank-Nullity Theorem, A counter-example would be a transformation that is not linear.

Yes, all linear transformations have a matrix representation. The theorem that establishes this is the Matrix Representation Theorem. This theorem states that given a linear transformation T : V → W where V and W are vector spaces over a field F, then there is a unique matrix A such that T(v) = Av for any v in V. This theorem proves that any linear transformation can be represented by a matrix.

A counter-example of a linear transformation that does not have a matrix representation is a transformation that maps a vector in one vector space to a vector in a different vector space. For example, if V is a vector space over the field F, and W is a vector space over another field K, then the linear transformation T : V → W does not have a matrix representation since the size of the matrix would need to be different for each vector in the different vector spaces.

Answer:
the interest rate for the savings account is 15%

Step-by-step explanation:

We can use the formula for simple interest to solve this problem:

Simple Interest = Principal x Rate x Time

Where:

Principal is the amount of money invested

Rate is the interest rate (as a decimal)

Time is the length of time the money is invested

We know that Troy placed $40,000 in a savings account with simple interest for 5 years and earned $30,000 in interest. So we can plug these values into the formula to get:

$30,000 = $40,000 x Rate x 5 years

Simplifying this expression, we get:

Rate = $30,000 ÷ ($40,000 x 5 years)

Rate = 0.15 or 15%

Therefore, the interest rate for the savings account is 15%.
