The matrix A of T is given by A = [−4 2;1 -5].

Let T be a linear transformation from R² to R², such that T([1 0]) = [-4 1] and T([0 1]) = [2 -5].

We are to find the matrix A of T.

Linear transformations are functions that satisfy two properties.

These properties are additivity and homogeneity.

Additivity means that the sum of T(x + y) is equal to T(x) + T(y), while homogeneity means that T(cx) = cT(x).

Let A be the matrix of T.

Then, [T(x)] = A[x], where [T(x)] and [x] are column vectors.

This means that A[x] = T(x) for any vector x in R².

We can compute the first column of A by applying T to the standard basis vector [1 0] in R².

That is, [T([1 0])] = A[1 0].

Substituting T([1 0]) = [-4 1], we have -4 = a11 and 1 = a21.

We can compute the second column of A by applying T to the standard basis vector [0 1] in R².

That is, [T([0 1])] = A[0 1].

Substituting T([0 1]) = [2 -5], we have 2 = a12 and -5 = a22.

Therefore, the matrix A of T is given by A = [−4 2;1 -5].

Step-by-step explanation:

Given that P is the midpoint of QR, the length of QR is twice the length of PQ (or PR). Among the options provided, the correct answer is D, which is 43.

Let's assume that P is the midpoint of QR. In a line segment with a midpoint, the distance from one endpoint to the midpoint is equal to the distance from the midpoint to the other endpoint.

So, if P is the midpoint of QR, we can say that PQ is equal to PR. Therefore, the length of QR would be twice the length of PQ (or PR).

Given the answer choices, we need to find the length of QR among the options provided (A, B, C, D). We can eliminate options A and C because they are not even numbers, and it's unlikely for a midpoint to result in a decimal value.

Now, let's check options B and D. If we divide them by 2, we get 19 and 21.5, respectively. Since we're dealing with a line segment, it is more reasonable for the length to be a whole number. Therefore, we can conclude that the correct answer is option D, which is 43.

Hence, the length of QR is 43.

The yield to maturity of a ten-year, $1000 bond with a 5.2% coupon rate and semi-annual coupons, if the =bond is currently trading for a price of $884, is 6.23%. Thus, option a and option b is correct

Yield to maturity (YTM) is the anticipated overall return on a bond if it is held until maturity, considering all interest payments. To calculate YTM, you need to know the bond's price, coupon rate, face value, and the number of years until maturity.

The formula for calculating YTM is as follows:

YTM = (C + (F-P)/n) / ((F+P)/2) x 100

Where:

C = Interest payment

F = Face value

P = Market price

n = Number of coupon payments

Given that the bond has a coupon rate of 5.2%, a face value of $1000, a maturity of ten years, semi-annual coupon payments, and is currently trading at a price of $884, we can calculate the yield to maturity.

First, let's calculate the semi-annual coupon payment:

Semi-annual coupon rate = 5.2% / 2 = 2.6%

Face value = $1000

Market price = $884

Number of years remaining until maturity = 10 years

Number of semi-annual coupon payments = 2 x 10 = 20

Semi-annual coupon payment = Semi-annual coupon rate x Face value

Semi-annual coupon payment = 2.6% x $1000 = $26

Now, we can calculate the yield to maturity using the formula:

YTM = (C + (F-P)/n) / ((F+P)/2) x 100

YTM = (2 x $26 + ($1000-$884)/20) / (($1000+$884)/2) x 100

YTM = 6.23%

Therefore, If a ten-year, $1000 bond with a 5.2% coupon rate and semi-annual coupons is now selling at $884, the yield to maturity is 6.23%.

The cost of each printer is $568.

To find the cost of each printer, we need to use a system of equations.

Let's call the cost of each printer "p" and the cost of each camera "c".

The first equation we can create is: 6p + 3c = 4773

The second equation we can create is: 4p + 6c = 5002

Now we can use the elimination method to solve for one of the variables.

Let's eliminate the "c" variable by multiplying the first equation by -2: -12p - 6c = -9546

And then add the two equations together: -8p = -4544

Now we can solve for "p" by dividing both sides by -8: p = 568

So the cost of each printer is $568.

To find the cost of each camera, we can plug the value of "p" back into one of the original equations and solve for "c":

6(568) + 3c = 4773

3408 + 3c = 4773

3c = 1365

c = 455

So the cost of each camera is $455.

Therefore, the cost of each printer is $568 and the cost of each camera is $455.

Answer:

Factor:

=(3x+8)(3x−8)

3x – 8

The solutions to the equation -30x² + 9x + 60 = 0 are x = 5/2 and x = -4/5.

To solve the equation, we can start by bringing all the terms to one side to have a quadratic equation equal to zero. Let's go step by step:

-5/3 x² + 3x + 11 = -9 + 25/3 x²

First, let's simplify the equation by multiplying each term by 3 to eliminate the fractions:

-5x² + 9x + 33 = -27 + 25x²

Next, let's combine like terms:

-5x² - 25x² + 9x + 33 = -27

-30x² + 9x + 33 = -27

Now, let's bring all the terms to one side to have a quadratic equation equal to zero:

-30x² + 9x + 33 + 27 = 0

-30x² + 9x + 60 = 0

Finally, we have the quadratic equation in standard form:

-30x² + 9x + 60 = 0

Dividing each term by 3, we get:

-10x² + 3x + 20 = 0

(-2x + 5)(5x + 4) = -10x² + 3x + 20

So, the factored form of the equation -30x² + 9x + 60 = 0 is:

(-2x + 5)(5x + 4) = 0

Now we can set each factor equal to zero and solve for x:

-2x + 5 = 0 --> x = 5/2

5x + 4 = 0 --> x = -4/5

a) the dimension of its column space is also 2. b) the rank of A is 2. c) the nullity of matrix A is 1. d) the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

(a) The dimension of the row space of a matrix is equal to the dimension of its column space. So, if the dimension of the row space of matrix A is 2, then the dimension of its column space is also 2.

(b) The rank of a matrix is defined as the maximum number of linearly independent rows or columns in the matrix. Since the dimension of the row space of matrix A is 2, the rank of A is also 2.

(c) The nullity of a matrix is defined as the dimension of the null space, which is the set of all solutions to the homogeneous equation Ax = 0. In this case, the matrix A is a 3 x 3 matrix, so the nullity can be calculated using the formula:

nullity = number of columns - rank

nullity = 3 - 2 = 1

Therefore, the nullity of matrix A is 1.

(d) The dimension of the solution space of the homogeneous system Ax = 0 is equal to the nullity of the matrix A. In this case, we have already determined that the nullity of matrix A is 1. Therefore, the dimension of the solution space of the homogeneous system \(A_x = 0\) is also 1.

Vector equation of the line tangent to the graph of r(t) at the point p0 on the curve r(t) = (3t - 1) i + 13t j + 4 k.

To find a vector equation of the line tangent to the graph of r(t) at the point P0 on the curve r(t) = (3t - 1) i + 13t j + 16 k, where P0 is given as (-1,4), we can use the following steps:

Step 1: Find the derivative of r(t) with respect to t:

r'(t) = 3 i + 13 j

Step 2: Evaluate the derivative at the point P0:

r'(-1) = 3 i + 13 j

Step 3: Use the point P0 and the vector r'(-1) to form the vector equation of the tangent line:

r(t) = P0 + r'(-1) t

where t is a scalar parameter.

Plugging in the values, we get:

r(t) = (-1)i + 4j + (3i + 13j)t

Simplifying, we get:

r(t) = (3t - 1) i + 13t j + 4 k

Therefore, the vector equation of the line tangent to the graph of r(t) at the point P0 on the curve

r(t) = (3t - 1) i + 13t j + 16 k  is

The GRE score at the upper quartile is approximately A) 613.

To find the GRE score at the upper quartile Q3, we need to first find the z-score of Q3 and then convert it back into the original units using the formula:

z = (x - μ) / ơ

where z is the standard score, x is the GRE score, μ is the mean, and ơ is the standard deviation.

The upper quartile Q3 is the 75th percentile of the distribution, which means that 75% of the scores in the distribution fall below Q3 and 25% of the scores fall above it. Using a standard normal table or a calculator, we can find the z-score corresponding to the 75th percentile, which is approximately 0.67.

Plugging in the values of μ, ơ, and the z-score into the formula for z, we get:

0.67 = (x - 544) / 103

Solving for x, we get:

x = 103(0.67) + 544

x = 613.01

Given the following :

Amount Noah borrowed from his mother = $17

Amount paid = $8

Change in the amount of money Noah's mother has :

Let initial amount her mother has = x

Hence, the amount she has after Noah paid $8 to her will be :

Initial amount - amount borrowed + amount paid

= x - $17 + $8.

The simplified amount = x - $9

The amount Noah still owes :

Total amount owed - amount paid

$17 - $8 = $9

The change in the amount of money that Noah's mother will be $ 9.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Noah borrowed $17 from his mother. He then paid back $8 of the amount he owed.
