What are some conversion factors?

When sales are under $15,000, the current job pays less than the new offer. The new job offer is therefore favoured for sales below $15,000.

a)   Wc = 2000+.07S

b)  Wn =2300+.05S

c)  When the totals are similar, the sales level at which she would not care

   2000 + .07S = 2300 + .05S

   subtract .05S from both sides

    2000 +.02S = 2300

   subtract 2000 from both sides

    .02S = 300

   divide both sides by .02

   S = 300/.02 = 15000

Sales of $15,000 equate to identical pay.

If we apply the same calculation, substituting less than for the = sign... The result of our equation is

2000 + .07S < 2300 + .05S

S < 15000

The present employment pays less than the new offer when sales are under $15,000. Therefore, the new job offer is preferred for sales below $15,000.

check:  Let S = 10,000

Wc = 2000+.07(10000) = $2700

Wn = 2300 + .05(10000) = $2800

As can be seen, at sales of $10,000 the new job earns more.

The complete question is:

A salesperson receives a monthly salary $2000 plus commission of 7% of sales. she is offered a new job at $2300 per month plus commission of 5% os sales.

b)write a linear equation for her monthly wage W of the job offer in terms of her monthly sales S.

Answer:

Step-by-step explanation:

So if they sell approximately 376 pizzas the first shift and then the same amount for the second, all you have to do is add 376 by 367 or multiply by 2 because adding the same number twice is like multiplying the number by 2.

Answer: 564

Step-by-step explanation: From 10-2 they sell 376 pizzas. So, in 4 hours they sell 376 pizzas, and they sell 94 pizzas per hour, because 376/4 is 94. So from 5-7, 2 hours, they should sell 94 times 2 pizzas, which is 188 pizzas. So 188+376 is 564.

Parabola A and parabola B are similar in that they are both vertically oriented parabolas with the x-axis as their axis of symmetry. However, they differ in their vertex, focus, and directrix, which means they have different equations and open in different directions.

Both parabola A and parabola B are examples of vertically oriented parabolas that have the x-axis as their axis of symmetry. However, they differ in their vertex, focus, and directrix.

Parabola A has its vertex at (0, 0) and its focus at (0, 4). The directrix is the line y = -4, which is a horizontal line 4 units below the vertex. This means that any point on parabola A is equidistant to the vertex and the focus, and the distance between any point on the parabola and the directrix is equal to the distance between the point and the focus.

Parabola B has its vertex at (0, 0) and its focus at (0, -6). The directrix is the line y = 6, which is a horizontal line 6 units above the vertex. This means that any point on parabola B is equidistant to the vertex and the focus, and the distance between any point on the parabola and the directrix is equal to the distance between the point and the focus.

In terms of their equations, the equation of parabola A is y^2 = 16x, while the equation of parabola B is y^2 = -24x. Notice that parabola B has a negative coefficient of x, which means it opens to the left instead of the right like parabola A.

Answer:

To solve this problem, we need to start by setting up an equation. The equation should express the fact that the result of the two operations on the fractions is both 4 and 5/4.

We can do this by writing:

4x/(x-2) = 4

5x/2(x-2) = 5/4

Solving for x, we get x=16. Therefore, the fraction we are looking for is 4/14, since 4 times 16 divided by 16 minus 2 equals 4 and 5 times 16 divided by 2 times 16 minus 2 equals 5/4.

Part (a)

The error happens on the 2nd step.

The student multiplied both sides by the LCD (x+3)(x-3) to clear out the fractions, but forgot about the first "1" at the very left.

It is calculated by dividing the required value by the total value and multiplying it by 100.

To determine if the purchase of negative points is a wise decision, we first need to calculate Millie's monthly payment with and without the negative points.

Without negative points:

Principal = $600,000

Interest rate = 3.49%

Loan term = 25 years or 300 months

Now,

Monthly Payment = $2,967.27

With negative points:

Millie needs to purchase 2 negative points to cover the bank's closing cost. Each negative point will increase her APR by 0.125%, so the new interest rate will be:

New interest rate.

= 3.49% + (2 x 0.125%)

= 3.49/100 + (2 x 0.125/100)

= 3.74%

Monthly Payment = $2,998.84

The breakeven time.

This is the amount of time it takes for the cost of the negative points to be offset by the savings in monthly payments.

The total cost of the negative points.

We see that,

Each negative point costs 1% of the principal.

Cost of negative points,

= 2 x $6,000

= $12,000

The breakeven time.

Monthly savings.

= $2,967.27 - $2,998.84

= -$31.57

i.e

The value is negative because the new monthly payment is higher.

So,

Breakeven time.

= $12,000 ÷ -$31.57

= 380.2 months

This is,

1 year = 12 months

so,

31.7 years

Thus,

Breakeven's time is 31.7 years.

The loan term is only 25 years, so it does not make sense to purchase the negative points.

Less than half as many students own 3 or more devices as compared to students who own 1 device is true because 18 students own 1 device, the half of them is 9, and the number of students own 3 or more devices is 7 which is less than 9.

About 10 more students own 1 device than own 3 or more devices is true because the difference between students own 1 device and those own 3 or more devices = 18 - 7 = 11 which is about 10 more.

No, a matrix does not have to be symmetric to be orthogonally diagonalizable. Orthogonal diagonalization is a property of square matrices that can be used to simplify calculations and solve certain types of problems.

A square matrix A is orthogonally diagonalizable if there exists an orthogonal matrix P and a diagonal matrix D such that A = PDP^T, where D contains the eigenvalues of A and P contains the corresponding eigenvectors.

A symmetric matrix is always orthogonally diagonalizable, meaning that there exists an orthogonal matrix P such that A = PDP^T, where D is a diagonal matrix containing the eigenvalues of A. However, not all matrices are symmetric and still can be orthogonally diagonalizable.

For a non-symmetric matrix, the eigenvectors and eigenvalues may not have certain symmetrical properties that make orthogonal diagonalization straightforward, but it is still possible to diagonalize the matrix. In such cases, we can use other techniques, such as the Schur decomposition, to obtain a similar diagonal form.

In summary, a matrix does not have to be symmetric to be orthogonally diagonalizable, but symmetric matrices are always orthogonally diagonalizable. Other techniques may be used for diagonalizing non-symmetric matrices.

2) 12 degrees

Step-by-step explanation:

1)

We can start by drawing a diagram of the situation. Let's label the height of the tower as "h", the distance from the airplane to the tower as "d", and the angle of depression as 56°.

  C (top of tower)

               /|

              / |

             /  |h

            /   |

           /θ   |

    A_____/_____|

        d   B

In this diagram, point A represents the airplane, point B represents the base of the tower, and point C represents the top of the tower. The angle θ is the angle of depression from the airplane to the top of the tower.

We can use trigonometry to solve for the distance "d" from the airplane to the tower. In particular, we know that:

tan(θ) = h / d

We can rearrange this equation to solve for "d":

d = h / tan(θ)

Substituting the values we know, we get:

d = 320 / tan(56°)

Using a calculator, we can evaluate this to get:

d ≈ 215.8 feet

However, the airplane is flying at an altitude of 7,450 feet, so we need to add this to the height of the tower to get the total distance from the airplane to the ground:

total distance = d + 320 + 7,450

Plugging in the value we found for "d", we get:

total distance ≈ 7995.8 feet

Rounding to the nearest tenth, we get:

total distance ≈ 7995.8 ≈ 7995.9 feet

2)

We can use the tangent function to find the angle of depression. Let theta be the angle of depression. Then:

tan(theta) = (275 / 1324)

We can solve for theta by taking the inverse tangent (or arctan) of both sides:

theta = arctan(275 / 1324)

Using a calculator, we find:

theta ≈ 11.92 degrees

Rounding to the nearest whole number, we get:

The angle of depression is approximately 12 degrees.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5
