In 138 years time, john will reach to the top scale and the total amount he would earn during this period will be $1380000.

We have John who started his employment with a salary of $120,000 per annum which was increased by $10,000 every year up to the top of the scale of $1,500,000 per annum.

We can write the equation governing the increase as -

y = 120000 + 10000x

For -

y = 1500000, we can write -

1500000 = 120000 + 10000x

10000(12 + x) = 1500000

x + 12 = 150

x = 138 years

The total amount he would earn during this period will be -

A = 10000 x 138 = $1380000

Therefore, in 138 years time, john will reach to the top scale and the total amount he would earn during this period will be $1380000.

If {v1, v2, v3} is an orthogonal basis for W, then multiplying v3 by a scalar c gives a new orthogonal basis {v1, v2, cv3 } is false statement.

Orthogonal basis:

Linear algebra, the orthogonal basis V of the inner product space is the basis of V whose vectors are mutually orthogonal.

When a vector of orthogonal basis is normalized, the resulting basis is an orthonormal basis.

let W be a vector space. The set S= {v₁,v₂,v₃} is an orthogonal basis for W.

The number of basis elements in W = 3 that is the dimensions of W is three.

If we multiply v₃ by c =0, then the set becomes

{v₁, v₂, cv₃} = {v₁, v₂,0}. The dimension of the set is 2, that is less than the dimension of W. If the scalar factor is 0, then it will not give a new orthogonal basis. Since in this case the number of basis elements will be reduced by 1 hence will change dimension of W.

Therefore, The statement is False.

Answer: .29

Step-by-step explanation:

The absolute maximum and absolute minimum of f(x,y) = 3 + xy -x - 2y is f(0,0) and f(1,1) respectively.

The absolute maximum point is a point where the function obtains its greatest possible value.

And Absolute minimum is a point where the function obtains its least possible value. This is the smallest value that a mathematical function can have over its entire curve.

Given equation is, f(x,y) = 3 + xy - x - 2y

we will check absolute maximum and absolute minimum of f(x,y) at the points (0,0), (1,0), (1,1).  

f(0,0) = 3 + (0)(0) - 0 - 2(0) = 3

f(1,0) = 3 + (1)(0) - 1 - 2 (0) = 2

f(1,1) = 3 + (1)(1) - 1 - 2(1) = 1

Therefore we get absolute maximum at f(0,0) and absolute minimum at f(1,1).

An absolute minimum also called a global minimum, occurs when a point of the function is lower any other point on the function within the function's domain. A local minimum also called relative minimum occurs when a point is lower than the points surrounding it.

Given question is incomplete. Complete question is:

We take carry 1 if there is more then 9 when we are adding or subtracting in the regrouping 4 digit number.

Given that,

We have to find how do we regroup 4 digit numbers.

We know that,

When performing operations like subtraction and addition, regrouping is accomplished by creating groups of tens. Regrouping refers to rearranging integers into place value-based groupings to facilitate operations. Because you must rearrange the numbers into place value to complete the procedure, it is known as regrouping.

Addition with regrouping or addition with carryover refers to additions where the addends' digit sums exceed 9 in any of the columns. Finding the digit sum of two integers requires regrouping. Only the units place digit of the total is then written in the appropriate column.

The least squares estimated regression line is  0.5x+1.667

If your data shows a linear relationship between the X and Y variables, you will want to find the line that best fits that relationship. That line is called a Regression Line and has the equation ŷ= a + b x. The Least Squares Regression Line is the line that makes the vertical distance from the data points to the regression line as small as possible. It’s called a “least squares” because the best line of fit is one that minimizes the variance (the sum of squares of the errors).

Data rarely fit a straight line exactly. Usually, it is satisfactory with rough predictions. Typically, you have a set of data whose scatter plot appears to “fit” a straight line. This is called a Line of Best Fit or Least-Squares Line.

a. The equation for the transformed function is y = -2(x + 4)^2 - 3.

b. The graph of the transformed function will be a parabola with a vertex located at (x,y)=(-4,-3). The parabola will open downwards, have a maximum at -3, and have a line of symmetry along the x-axis. The parabola will have an x-intercept at x=-4, and will stretch outwards to the right and left infinitely. The graph will look like a U-shaped curve that is shifted down 3 units and has a maximum at -3.

To begin, we can start with the equation of a standard parabola, y=x^2. To shift the parabola 4 units to the left, we can add a -4 to the x term in the equation, giving us y=x^2-4. To stretch the parabola vertically by a factor of 2, we can multiply the equation by -2, giving us y=-2(x^2-4). To reflect the parabola over the x-axis, we can multiply the equation by -1, giving us y=-2(x^2-4) -3. This gives us the equation y=-2(x+4)^2 - 3, which is the equation of the transformed function.

Two angles are called linear pairs if they are supplementary, that is, if the sum of their measures is of 180º.

In this problem, we have that two angles form a linear pair, hence:

The length of the rectangle is calculated to be 9 inches if the length of the rectangle is 3 inches greater than its width

The formula for the perimeter of a rectangle can be given as follows;

perimeter = 2 ( x + y )

Here x represents length and y represents width;

Since the length of a rectangle is 3 Inches more than its width, therefore;

x = y + 3

Since the perimeter of the rectangle is 30 inches, therefore;

2 ( x + y ) = 30

Simplifying by dividing both sides by 2 as follows;

2 ( x + y ) / 2 = 30 / 2

x + y = 15

As x = y + 3; substituting this value in x + y = 15 as follows;

y + 3 + y = 15

Rearranging;

y + y + 3 = 15

2y + 3 = 15

2y = 15 - 3

2y = 12

y = 12 / 2

y = 6
