Reflecting across Both Axes Suppose (-7,3) is reflected across the x-axis, and then the y-axis. What will be the new coordinates? A. (-7,-3) B. (-7,3) C. (7,-3) D. (7,3)

Answers

Answer 1

The coordinates after the reflection of the points will be(7, -3).

What is reflection over axes?

The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse.

Given that, (-7,3) is reflected across the x-axis, and then the y-axis.

When reflected across x-axis, it will be (-7, -3)

And again when reflected across y-axis it will be (7, -3)

Hence, The coordinates after the reflection of the points will be(7, -3)

What is the solution of the system of equations? y= x + 2, y = 3x

Answers

Answer:

[tex]x = 1 , y = 3[/tex]

Step-by-step explanation:

Note that each equation is equal to y. Set the equations equal to each other:

[tex]y = x + 2\\y = 3x\\\\x + 2 = y = 3x\\x + 2 = 3x[/tex]

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

[tex]x + 2 = 3x\\x (-x) + 2 = 3x (-x)\\2 = 3x - x\\2 = 2x[/tex]

Next, divide 2 from both sides of the equation:

[tex]2x = 2\\\frac{2x}{2} = \frac{2}{2} \\x = \frac{2}{2} = 1\\x = 1[/tex]

Next, plug in 1 for x in one of the given equations:

[tex]y = x + 2\\\\x = 1 \\[/tex](given).

[tex]y = (1) + 2\\y = 3[/tex]

[tex]x = 1 , y = 3[/tex] is your answer.

In a Roth IRA account, the $1000.00
investment is taxed at 10%. Which
plan reduces the overall tax burden?
A. The Traditional will reduce the tax burden because it's applied at a
higher percentage.
B. Both tax burdens will come out the same since both tax
calculations start with a $1000.00 account.
C. The Roth IRA reduces the tax burden because its taxes are
calculated in a lower bracket.
D. The Traditional IRA reduces the tax burden because its taxes are
calculated in a lower bracket.

Answers

C. The Roth IRA reduces the tax burden because its taxes are calculated in a lower bracket.

In a traditional IRA, contributions may be tax-deductible in the year they are made, but withdrawals in retirement are taxed as ordinary income. This means that the $1000.00 investment in a traditional IRA would be taxed at the investor's ordinary income tax rate when it is withdrawn in retirement. If the investor's ordinary income tax rate is 12%, then the tax burden on the $1000.00 investment in a traditional IRA would be $120.00.

In a Roth IRA, contributions are not tax-deductible, but withdrawals in retirement are tax-free. This means that the $1000.00 investment in a Roth IRA would be taxed at the investor's ordinary income tax rate when it is made, but it would not be taxed when it is withdrawn in retirement. If the investor's ordinary income tax rate is 10%, then the tax burden on the $1000.00 investment in a Roth IRA would be $100.00.

Overall, the tax burden on the $1000.00 investment in a Roth IRA is lower than the tax burden on the same investment in a traditional IRA because the taxes on the Roth IRA are calculated in a lower bracket (10% vs 12%).

Division C has received a quote of $58 from an outside supplier for a component part that is comparable to the one that Division B makes. If the company’s divisional managers are evaluated based on their division’s profits and Division B is currently selling 15,000 units on the outside market, what is Division C’s highest acceptable transfer price if it were to buy 4,000 units from Division B?

Answers

Division C’s highest acceptable transfer price if it were to buy 4,000 units from Division B should be $58.

What is the transfer price?

The transfer price is the price that Division B should charge Division C for the internal supply of goods or services.

Ordinarily, the transfer price equals the outlay cost (production cost) plus the opportunity cost (profit from selling outside).

The highest acceptable transfer price that Division C should reflect the market price at which Division C could acquire the parts from outside.

Division B:

Outside market selling price per unit = $60

Variable cost per unit = $44

Fixed cost per unit = $8

Capacity in units = 20,000 units

Units sold outside by Division B = 15,000 units

Excess units = 5,000 units (20,000 - 15,000)

Units required by Division C = 4,000 units

Outside supplier's price per unit = $58

Thus, the highest acceptable transfer price should be $58 and not $60.

Answers

A rectangle's greatest area is 32 square units.

Given:

A parabola's equation is y = 12 - x2, which is an even function

As a result, its rectangular shape is also even at the origin.

We are aware that the area of a rectangle is equal to its length times its width.

Here,

width = y, length = 2x

A = 2x, where (12 -  [tex]x^{2}[/tex])

⇒ A = 24x - 2[tex]x^{3}[/tex]

Consider the A derivative with regard to x.

⇒ A' = 24 - 6 [tex]x^{2}[/tex]

When A' = 0, the area is the largest.

⇒ 24 - 6x2 = 0

⇒ [tex]x^{2}[/tex] = 4

⇒ x = 2

Replace x with its value in y = 12 -  [tex]x^{2}[/tex].

⇒ y = 12 - 4

The U.S. Bureau of the Census prediction for the percentage of the population 65 years and older can be modeled as p(x) = −0.00022x3 + 0.014x2 − 0.0033x + 12.236 percent where x is the number of years since 2000, data from 0 ≤ x ≤ 50.

Answers

Part 1: The point of maxima is 21.212

Part 2: x = 21.212 is approximately equal to the year 2022

Part 3: The percentage at that time is 16.37%

Part 4: The rate of change of the percentage at that time is 0.294

Part 1:

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

where x is the number of years since 2000, data from 0<=x<=50

Differentiating the function with respect to x and equating it to 0

p'(x) = -0.00066x^2 + 0.028x - 0.0033

We will find the critical points of p'(x)

p''(x) = dp'(x)/dx  = -0.00132x + 0.028

Critical points of p'(x) lies at x where p''(x) = 0

Thus, -0.00132x + 0.028 = 0

x = 0.028/0.00132 = 21.212

Now, p'''(x) = -0.00132<0

x = 21.212 is a point of maxima of p'(x)

Therefore, the maximum possible values of x could lie at x = 21.212 as well as the extreme points of the domain p'(x), i.e. at x = 0 and 50

p'(0) = -0.00066(0)^2 + 0.028(0) - 0.0033 = -0.0033

p'(21.212) = -0.00066(21.212)^2 + 0.028(21.212) - 0.0033 = 0.2936

p'(50) = -0.00066(50)^2 + 0.028(50) - 0.0033 = -0.2533

Hence p'(x) attains maxima at x = 21.212

Therefore, p(x) increases most rapidly at x = 21.212

Part 2:

From the given condition in the question, x = 0 corresponds to the year 2000

Thus x = 21.212 is approximately equal to year 2022

Part 3:

The percentage at that time:

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

p(21.212) = -0.00022(21.212)^3 + 0.014(21.212)^2 - 0.0033(21.212) + 12.236

= 16.365

= 16.37%

Part 4:

Rate of change of the percentage at that time

p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236

p'(21.212) = -0.00066(21.212)^3 + 0.028(21.212) - 0.0033

= 0.2936

=0.294

the evaluation of the expression 2x−yz is 69.2.

What is polynomials?

Using variables and coefficients, polynomials are algebraic expressions. The term "indeterminates" is sometimes used to describe variables. For polynomial expressions, addition, subtraction, multiplication, and positive integer exponents are all arithmetic operations that are possible, however division by variables is not one of them. The polynomial x2+x-12 is an illustration of one with one variable. Three terms—x2, x, and -12—are included in this case.

the expression 2x−yz , where x=34 , y=−0.2 , and z = 6.

So putting the value of x,y and z.

2(34)- (-0.2*6) = 68+1.2

=69.2

Hence the evaluation of the expression is 69.2.
