Answers

a. The formula for the upper limit (U) is U = 220 - x, where x is the age of the person. The formula for the lower limit (L) is L = 0.65(220 - x).

b. For a 40-year-old person, the lower limit is L = 0.65(220 - 40) = 117 beats per minute and the upper limit is U = 220 - 40 = 180 beats per minute.

c. For a 60-year-old person, the lower limit is L = 0.65(220 - 60) = 104 beats per minute and the upper limit is U = 220 - 60 = 160 beats per minute.

d. Let x be the age of the younger woman and y be the age of the older woman. Since the older woman is 34 years older than the younger woman, we have y = x + 34. Since the older woman is working at the upper limit of her target heart rate zone and the younger woman is working at the lower limit of her target heart rate zone, we have U = L. Substituting the formulas for U and L, we get 220 - y = 0.65(220 - x). Substituting y = x + 34, we get 220 - (x + 34) = 0.65(220 - x). Simplifying and solving for x, we get x = 38. Therefore, the age of the younger woman is approximately 38 years and that of the older woman is approximately 72 years. Their pulse is approximately U = 220 - 72 = 148 beats per minute.

The product of these two matrices is a 3x3 matrix, AB.
AB = [[-9, -7, -1]

To determine AB, we need to multiply matrix A and matrix B. The dimensions of matrix A are 3x1 and the dimensions of matrix B are 1x3. Since the number of columns in matrix A is equal to the number of rows in matrix B, we can multiply these matrices. The resulting matrix will have the dimensions of the number of rows in matrix A and the number of columns in matrix B, which is 3x3.

To multiply the matrices, we take the dot product of each row in matrix A with each column in matrix B. The dot product is the sum of the products of the corresponding entries in the row and column.

AB = [[(-1)(-9) + (-6)(-7) + (7)(-1)], [(-1)(-9) + (-6)(-7) + (7)(-1)], [(-1)(-9) + (-6)(-7) + (7)(-1)]]

Answers

This |x - 32| <= 2 means that the tire pressure can be anywhere between 30 psi and 34 psi.

In order for Ms. Sartain's car to have optimal gas mileage, the tire pressure should remain within 2 psi of 32 psi at all times. This can be modeled with an absolute value inequality.

The absolute value inequality that models this situation is |x - 32| <= 2. This inequality states that the difference between the tire pressure, x, and the optimal pressure, 32, should be less than or equal to 2.

In other words, the tire pressure can be 2 psi above or below the optimal pressure of 32 psi and still be within the acceptable range. This means that the tire pressure can be anywhere between 30 psi and 34 psi.

So the correct answer is |x - 32| <= 2.

What is interest ?

Interest is the fee paid for the use of borrowed money, usually expressed as a percentage of the borrowed amount.

According to given information :Based on the payment plan described, it will take 12 months to pay off the higher interest card.The amount of the last payment on the higher interest card will be $173.01. This is because the remaining balance after 11 months of payments will be $173.01, which is the amount needed to fully pay off the card.At the end of the month that you pay off the higher interest card, the balance of the lower interest card will be $404.17. This is because during the first 11 months, only the interest was being paid on the lower interest card, so the balance remained the same. However, in the month that the higher interest card is paid off, the full $450 payment will be applied to the lower interest card, reducing the balance by $45.83 to $404.17.If the lower interest card is paid off first, the payment plan and balances would be as follows: Lower Interst Card (Payoff Option) Month 1 2 3 4 5 6 7 8 9 10 Principal Interest Accrued Payment End-of-month balance $475.00 $6.46 $6.46 $6.46 $6.46 $6.46 $6.46 $6.46 $6.46 $6.46 $0.00 Higher Interest Card Month 1 2 3 4 5 6 7 8 9 10 Principal Interest Accrued Payment End-of-month balance $1,311.48 $10.69 $10.69 $10.69 $10.69 $10.69 $10.69 $10.69 $10.69 $10.69 $0.00. Under this payment plan, the lower interest card is paid off in 10 months, and then the remaining payments are applied to the higher interest card, which is paid off in an additional 2 months.By paying off the higher interest card first, you save a total of $141.27 in interest charges over the course of the payment plan.

Therefore, 1. 9 months 2) $163.06, because it is the remaining balance after paying off the principal and interest accrued for that month. 3) $348.16, because it is the balance remaining on the lower interest card after paying off the higher interest card and making the monthly payment for that month. 4) 9 months 5) $168.79, because it is the difference between the total amount paid to each card when paying off the higher interest card first versus paying off the lower interest card first.

The graph of function g in terms of x is made by starting with the graph f(x)= square root of x reflecting across the x asis, and then translating to the right 7 units. Write an equation for g (x)

Answers

The equation of the graph of the function g(x) is -√(x-7).

What distinguishes a reflection from a translation?

Turns are frequently used to refer to reflection, which is when an object is flipped over a line without affecting its size or shape. The preimage is flipped over a line in a rigorous transition known as a reflection, but its size and shape are left unchanged. Flips is another name for reflections.

A figure can be translated if it is moved in any direction without altering its size, form, or orientation. A hard transformation called a translation alters the preimage's position but not its size, shape, or orientation. Slides are another name for translations.

Given that, f(x)= square root of x, that is:

f(x) = √x

Reflect the graph over x-axis we have:

Reflecting f(x) across the x-axis gives us -f(x) = -√x.

Translating -f(x) = -√x 7 units to the right gives us -f(x-7) = -√(x-7).

Hence, the equation of the graph of the function g(x) is -√(x-7).

(b) Use the QR factorization of $A$ in part (a) to solve the equation $Ax = b,$ where $b = \begin{bmatrix} 3 \\ 1 \\ 2 \\ 1 \end{bmatrix}.$The Gram-Schmidt algorithm is a numerical method to produce orthonormal basis of a subspace in Hilbert space that spans the same space, which makes the basis more convenient to work with. As for the first part of the question, let us begin by applying the Gram-Schmidt algorithm to $a^1, a^2, a^3.$ We begin by defining $q_1 = a^1 / \|a^1\|.$ Hence,$$q_1 = \frac{1}{3}\begin{bmatrix} 1 \\ 1 \\ 2 \\ 1 \end{bmatrix} = \begin{bmatrix} 1/3 \\ 1/3 \\ 2/3 \\ 1/3 \end{bmatrix}.$$Next, we define $v_2 = a^2 - \langle q_1, a^2 \rangle q_1.$ Therefore,$$v_2 = a^2 - \frac{-1}{3}(1/3)q_1 = \begin{bmatrix} -7/9 \\ 8/9 \\ -2/9 \\ -4/9 \end{bmatrix}.$$Now, we can define $q_2 = v_2 / \|v_2\|.$ Thus,$$q_2 = \frac{1}{3}\begin{bmatrix} -7 \\ 8 \\ -2 \\ -4 \end{bmatrix}.$$Finally, we define $v_3 = a^3 - \langle q_1, a^3 \rangle q_1 - \langle q_2, a^3 \rangle q_2.$ Then,$$v_3 = a^3 - \frac{5}{9}q_1 - \frac{7}{27}q_2 = \begin{bmatrix} -1/27 \\ 5/9 \\ 22/27 \\ -5/27 \end{bmatrix}.$$Lastly, we can define $q_3 = v_3 / \|v_3\|,$ so$$q_3 = \frac{1}{3}\begin{bmatrix} -1 \\ 5 \\ 22 \\ -5 \end{bmatrix}.$$Now, we can write $A = QR$ as $$\begin{bmatrix} a^1 & a^2 & a^3 \end{bmatrix} = \begin{bmatrix} q_1 & q_2 & q_3 \end{bmatrix} \begin{bmatrix} r_{11} & r_{12} & r_{13} \\ 0 & r_{22} & r_{23} \\ 0 & 0 & r_{33} \end{bmatrix}.$$We can obtain the entries of the $R$ matrix by calculating the inner product of each $q_i$ with $a^j.$ Thus,$$r_{11} = \|a^1\| = \sqrt{7},$$$$r_{12} = \langle q_1, a^2 \rangle = \frac{-1}{3}\sqrt{7},$$$$r_{13} = \langle q_1, a^3 \rangle = \frac{5}{9}\sqrt{7},$$$$r_{22} = \|v_2\| = \frac{5}{3}\sqrt{2},$$$$r_{23} = \langle q_2, a^3 \rangle = \frac{-7}{9}\sqrt{2},$$$$r_{33} = \|v_3\| = \frac{2}{3}\sqrt{6}.$$Therefore,$$\begin{bmatrix} a^1 & a^2 & a^3 \end{bmatrix} = \begin{bmatrix} q_1 & q_2 & q_3 \end{bmatrix} \begin{bmatrix} \sqrt{7} & -\frac{1}{3}\sqrt{7} & \frac{5}{9}\sqrt{7} \\ 0 & \frac{5}{3}\sqrt{2} & -\frac{7}{9}\sqrt{2} \\ 0 & 0 & \frac{2}{3}\sqrt{6} \end{bmatrix}.$$Now, let us solve the equation $Ax = b$ by using the QR factorization of $A.$ We can write $Ax = QRx = b.$ Since $Q$ is orthogonal, we can multiply both sides of the equation by $Q^T$ to obtain $Rx = Q^Tb.$ Note that $Q^Tb$ is easy to compute since $Q^T$ is just the matrix with the $q_i$'s as rows. Thus,$$\begin{bmatrix} \sqrt{7} & -\frac{1}{3}\sqrt{7} & \frac{5}{9}\sqrt{7} \\ 0 & \frac{5}{3}\sqrt{2} & -\frac{7}{9}\sqrt{2} \\ 0 & 0 & \frac{2}{3}\sqrt{6} \end{bmatrix} \begin{bmatrix} x_1 \\ x_2 \\ x_3 \end{bmatrix} = \begin{bmatrix} \frac{2}{3} \\ \frac{1}{3} \\ \frac{2}{3} \end{bmatrix}.$$This gives the system of equations$$\begin{cases} \sqrt{7}x_1 - \frac{1}{3}\sqrt{7}x_2 + \frac{5}{9}\sqrt{7}x_3 = \frac{2}{3}, \\ \frac{5}{3}\sqrt{2}x_2 - \frac{7}{9}\sqrt{2}x_3 = \frac{1}{3}, \\ \frac{2}{3}\sqrt{6}x_3 = \frac{2}{3}. \end{cases}$$Solving the last equation for $x_3,$ we obtain $x_3 = 1.$ Substituting this into the second equation, we obtain $x_2 = \frac{1}{5}.$ Finally, substituting these values into the first equation gives us $x_1 = 1.$ Therefore,$$x = \begin{bmatrix} x_1 \\ x_2 \\ x_3 \end{bmatrix} = \begin{bmatrix} 1 \\ \frac{1}{5} \\ 1 \end{bmatrix}.$$

Factor the following polynomial given that it has a zero at 5 with multiplicity 2 . z^(4)-3z^(3)-63z^(2)+355z-450

Answers

Given that the polynomial has a zero at 5 with multiplicity 2, its complete factorization is (x - 5)²(z + 9)(z - 2).

To factor the given polynomial z⁴ - 3z³ - 63z² + 355z - 450, given that it has a zero at 5 with multiplicity 2, we can use the fact that (z - 5)² is a factor of the polynomial. We can then use synthetic division to find the other factors.

First, we divide the polynomial by (z - 5) using synthetic division:
5   |   1  -3  -63  355  -450
    |       5    10  -265  450
        1   2  -53    90       0

The result of the division is z³ + 2z² - 53z + 90 . Divide it by (z - 5) again since the multiplicity is 2.
5   |   1   2  -53    90
    |       5    35   -90

        1   7   -18      0

The result of the second division is z² + 7z - 18. This polynomial can still be factorized as (z + 9)(z - 2).

So, the final answer is:

z⁴ - 3z³ - 63z² + 355z - 450 = (x - 5)²(z + 9)(z - 2).

How would you modify the statement of the limit of a rational function?

Answers

This would give us a modified statement of the limit, which would be "the limit of the rational function as x approaches 4".

What is rational function?

A rational function is a type of mathematical function that can be expressed as the ratio of two polynomials. It can be written in the form f(x) = p(x)/q(x), where p(x) and q(x) are polynomials with q(x) not equal to zero. Rational functions are used to model many real-world phenomena, such as the rate of change of a quantity with respect to another. They can also be used to solve complex equations and to analyze the behavior of a system.

The statement of the limit of a rational function can be modified by substituting different values for the variable and determining the resulting limit. For example, if the limit of the rational function is as x approaches 3, then we can substitute x = 4 and determine the resulting limit. This would give us a modified statement of the limit, which would be "the limit of the rational function as x approaches 4".

What is the definition of a function?

In mathematics, a function is a relation between two sets of elements, called the domain and the range, such that each element in the domain corresponds to exactly one element in the range.

More specifically, a function is a rule that assigns each element of the domain (input) to a unique element in the range (output). The notation for a function f with domain D and range R is typically written as:

f: D → R

f is a function mapping elements from the domain D to elements in the range R.

Now,

To find the y-intercept of a function, we set x = 0 and evaluate the function.

For [tex]f(x) = -4(1.09)^x[/tex], when x = 0, we get:

[tex]f(0) = - 4(1.09)^0 = - 4[/tex]

So, the y-intercept of f(x) is -4.

For g(x), we are given a table of values, and we can see that when x = 0, g(x) = -4. Therefore, the y-intercept of g(x) is also -4.

Hence,

          The first option "The y-intercept of f(x) is equal to the y-intercept of g(x)" is the correct answer.

In a coordinate plane, shade the region that consists of all points that have positive x-and y-coordinates whose sum is less than 5. Write a system of three inequalities thatdescribes this region.

Answers

The system of three inequalities that describes this region is:x > 0y > 0x + y < 5

In a coordinate plane, the region that consists of all points that have positive x-and y-coordinates whose sum is less than 5 is the triangular region in the first quadrant bounded by the x-axis, y-axis, and the line x + y = 5. The system of three inequalities that describes this region is:x > 0y > 0x + y < 5Explanation:To find the region that consists of all points that have positive x-and y-coordinates whose sum is less than 5, we need to first graph the line x + y = 5 on a coordinate plane. This line has a slope of -1 and passes through the points (0,5) and (5,0). The region that we are looking for is the triangular region in the first quadrant bounded by the x-axis, y-axis, and this line.To write a system of three inequalities that describes this region, we need to consider the following facts:- All points in this region have positive x-coordinates, so x > 0.- All points in this region have positive y-coordinates, so y > 0.- All points in this region have x-and y-coordinates whose sum is less than 5, so x + y < 5.Therefore, the system of three inequalities that describes this region is:x > 0y > 0x + y < 5

What is the weighted mean, if each unit has the following weightings? (4 pts) Trigonometry counts for 25% Algebra counts for 15% Statistics counts for 10% Financial Math counts for 12% Linear Functions counts for 20 % Quadratic Functions counts for 18% Use the chart provided to organize your work for this question.

Answers

The weighted mean is a type of average that takes into account the relative importance of each data point. In this case, each unit has a different weighting, so we need to take that into account when calculating the weighted mean. Here is how to calculate the weighted mean:

1. Multiply each unit's weighting by its corresponding value.

2. Add up all of the products from step 1.

3. Divide the sum from step 2 by the sum of all the weightings.

Using the chart provided, here is how to calculate the weighted mean for this question:

Unit Weighting Value Product

Trigonometry 25% x 0.25x

Algebra 15% y 0.15y

Statistics 10% z 0.1z

Financial Math 12% a 0.12a

Linear Functions 20% b 0.2b

Quadratic Functions 18% c 0.18c

Weighted mean = (0.25x + 0.15y + 0.1z + 0.12a + 0.2b + 0.18c) / (0.25 + 0.15 + 0.1 + 0.12 + 0.2 + 0.18)

Weighted mean = (0.25x + 0.15y + 0.1z + 0.12a + 0.2b + 0.18c) / 1

Weighted mean = 0.25x + 0.15y + 0.1z + 0.12a + 0.2b + 0.18c

So the weighted mean is a combination of the values of each unit, weighted by their relative importance.

Two​ trains, Train A and Train​ B, weigh a total of 184 tons. Train A is heavier than Train B. The difference of their weights is 90 tons. What is the weight of each​ train?

Answers

Answer:

A: 137 tonsB: 47 tons

Step-by-step explanation:

You want the weights of trains A and B if the sum of their weights is 184 tons and the difference of their weights is 90 tons.

Equations

We can write the equations for the weights as ...

  A +B = 184

  A -B = 90

Solution

Adding the two equations gives ...

  2A = 274

  A = 137

Subtracting the second equation from the first gives ...

  2B = 94

  B = 47

Train A weighs 137 tons; train B weighs 47 tons.

Add: (x^(2)-4x+9)/(x^(2)+9x+20)+(x-37)/(x^(2)+9x+20) Solution These two fractions have the same denominator, s

Answers

The polynomial is  (x - 4)(x - 7)/(x + 4)(x + 5).

The question asks to add the two fractions (x^(2)-4x+9)/(x^(2)+9x+20) and (x-37)/(x^(2)+9x+20). To solve this problem, we can first simplify the denominator by factoring the polynomial:

Denominator: (x^(2)+9x+20) = (x + 4)(x + 5)


Now, we can rewrite the two fractions with this new denominator:

(x^(2)-4x+9)/(x + 4)(x + 5) + (x-37)/(x + 4)(x + 5)


Then, we can use the distributive property to expand the fractions and combine like terms:

(x^(2)-4x+9 + x-37)/(x + 4)(x + 5)

= (x^(2) - 3x - 28)/(x + 4)(x + 5)


Finally, we can simplify the numerator by combining like terms:

= (x^(2) - 3x - 28)/(x + 4)(x + 5)

= (x - 4)(x - 7)/(x + 4)(x + 5)

Find the remainder. r when a is divided by b. Write th numerical value only Given: a=-233,b=11. Answer

Answers

The remainder when -233 is divided by 11 is 9. To find the remainder when a is divided by b, we can use the formula:

r = a % b

Where % is the modulo operator, which gives the remainder when one number is divided by another.

In this case, we have a = -233 and b = 11. Plugging these values into the formula, we get:

r = -233 % 11

Using a calculator or doing the division by hand, we find that the remainder is -2. However, since we are looking for the positive remainder, we can add b to this value to get the correct answer:

r = -2 + 11 = 9

A P^(5),000 debit to be made to the Purchaser account was debited to Accounts payabhe instead.

Answers

The error that occurred is called a transposition error.

A transposition error is when two digits are reversed or transposed in an accounting transaction. In this case, the debit that was supposed to be made to the Purchaser account was instead debited to the Accounts Payable account.

To correct this error, we need to make a journal entry that reverses the incorrect entry and then make the correct entry. The journal entry to reverse the incorrect entry would be:

Debit: Accounts Payable $5,000
Credit: Purchaser $5,000

This entry reverses the incorrect debit to Accounts Payable and the incorrect credit to Purchaser.

Next, we need to make the correct entry, which is:

Debit: Purchaser $5,000
Credit: Accounts Payable $5,000

This entry correctly debits the Purchaser account and credits the Accounts Payable account.

After these two journal entries are made, the accounts will be correctly balanced and the error will be corrected.

Find the standard matrix for the stated composition of linear
operators on R2.
A rotation of 270∘ (counterclockwise), followed by a
reflection about the line y = x.

Answers

The standard matrix for the stated composition of linear operators on R2 is:

| -1  0 |
|  0 -1 |

The standard matrix for the stated composition of linear operators on R2 can be found by multiplying the matrices for each individual operation.

First, let's find the matrix for a rotation of 270° counterclockwise:

| 0 -1 |
| 1  0 |

Next, let's find the matrix for a reflection about the line y = x:
| 0  1 |
| 1  0 |

Now, let's multiply these two matrices to find the standard matrix for the composition of these two operations:
| 0 -1 |   | 0  1 |   | -1  0 |
| 1  0 | * | 1  0 | = |  0 -1 |

Therefore, the standard matrix for the stated composition of linear operators on R2 is:
| -1  0 |

The graph is symmetric about the y-axis, so its a even function.

Define the even and odd function?The function is even if it is exactly what it was that originally started with (it is, if f (-x) = f (x), with all the signs remaining the same. The function is odd if it is exactly the opposite of just what it started with (it is, if (−x) = −f (x), with all the signs switched.

EVEN function:

This is "symmetric around the y-axis," meaning that what ever the graph is now doing with one side of such y-axis is replicated on the other, if I graph it.A distinguishing feature of even functions is this duplication about the y-axis.

ODD function:

This is "symmetric around the origin," as can be shown if I graph it; to do this, I would start at a point on the graph that is across one side of the y-axis, draw a line through the origin, then extend that same line for the opposite side of the y-axis.The peculiar symmetry of odd functions is well known.

Thus, the graph is symmetric about the y-axis, so its a even function.
