Functions (c) L(1) = C1 + AC and (d) L(1) = C°1 are linear operators on R^n, while functions (a), (b), and (e) do not satisfy the properties of linearity and therefore are not linear operators.

a) L(A) = 1 - 1: This function is not a linear operator because it does not preserve scalar multiplication. Multiplying A by a scalar c would yield L(cA) = c - c, which is not equal to cL(A) = c(1 - 1) = 0.

b) L(A) = 1 + 17: Similar to the previous case, this function is not linear since it fails to preserve scalar multiplication. Multiplying A by a scalar c would result in L(cA) = c + 17, which is not equal to cL(A) = c(1 + 17) = c + 17c.

c) L(1) = C1 + AC: This function is a linear operator since it satisfies both the preservation of addition and scalar multiplication properties. Adding matrices A and B and multiplying the result by scalar c will yield L(A + B) = C(1) + AC + C(1) + BC = L(A) + L(B), and L(cA) = C(1) + cAC = cL(A).

d) L(1) = C°1: This function is a linear operator since it satisfies the properties of linearity. Addition and scalar multiplication are preserved, and L(cA) = C(0)1 = c(C(0)1) = cL(A).

e) L(1) = 1?C: This function is not a linear operator as it does not preserve scalar multiplication. Multiplying A by a scalar c would give L(cA) = 1?(cC), which is not equal to cL(A) = c(1?C).

In summary, functions (c) L(1) = C1 + AC and (d) L(1) = C°1 are linear operators on R^n, while functions (a), (b), and (e) do not satisfy the properties of linearity and therefore are not linear operators.

Step-by-step explanation:

General equation of an ellipse

\(\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1 \quad \textsf{where }(h \pm a,k)\: \textsf{and}\:(h, k \pm b)\: \textsf{are the vertices}\)

Major Axis:  longest diameter of an ellipse

Minor Axis:  shortest diameter of an ellipse

Major radius:  one half of the major axis

Minor radius:  one half of the minor axis

If a > b the ellipse is horizontal, a is the major radius, and b is the minor radius.

If b > a the ellipse is vertical and b is the major radius, and a is the minor radius.

Given equation:

\(\dfrac{(y-4)^2}{25}+\dfrac{x^2}{9}=1\)

\(\implies \dfrac{x^2}{9}+\dfrac{(y-4)^2}{25}=1\)

Comparing with the general equation:

As b > a then the ellipse is vertical and b is the major radius.

⇒ Major axis = 2 × Major Radius

                      = 2b

                      = 2 × 5

The composition of the relations S ◦ R; S ◦ R is the relation {(1, 1), (1, 2), (2, 1), (2, 2), (3, 2), (3, 3)}.

To find the composition of the relations S ◦ R, you need:

1. Identify the pairs in R and S.
2. For each pair in R, find the pairs in S that have the first element equal to the second element of the pair in R.
3. Form new pairs by combining the first element of the pair in R and the second element of the pair in S.

Given relations:
R = {(1, 2), (1, 3), (2, 3), (2, 4), (3, 1)}
S = {(2, 1), (3, 1), (3, 2), (4, 2)}

Now, let's find S ◦ R:

1. For pair (1, 2) in R, we have (2, 1) in S. The new pair is (1, 1).
2. For pair (1, 3) in R, we have (3, 1) and (3, 2) in S. The new pairs are (1, 1) and (1, 2).
3. For pair (2, 3) in R, we have (3, 1) and (3, 2) in S. The new pairs are (2, 1) and (2, 2).
4. For pair (2, 4) in R, we have (4, 2) in S. The new pair is (2, 2).
5. For pair (3, 1) in R, we have (1, 2) and (1, 3) in R. The new pairs are (3, 2) and (3, 3).

Combining all the new pairs, we have:
S ◦ R = {(1, 1), (1, 2), (2, 1), (2, 2), (3, 2), (3, 3)}

So, S ◦ R is the relation {(1, 1), (1, 2), (2, 1), (2, 2), (3, 2), (3, 3)}.

If length of AZ=8 units and the length of ZX=4, then the length of the side XB is 6 units

Consider the triangle ABC

The points X and Y are on the line AB and Y is on the line AC

The lines XY and BC are parallel

Therefore

AX / XB = AY / YC

Similarly, the lines ZY and XC are parallel

AZ /  ZX = AY /  YC

Therefore the the proportion will be

AX / XB = AZ / ZX

The length of the line AX = AZ + ZX

= 8 + 4

= 12 units

Then the proportion will be

12 / XB = 8 / 4

Cross multiply the terms

12 × 4 = 8 × XB

XB = (12 × 4) / 8

XB = 48 / 8

XB = 6 units

Answer:

Step-by-step explanation:

Triangle A, transforms into a smaler size, and goes into full shape. Triangle B, goes into the negative numbers.

The options that can be used to find m∠abc are:

m∠abc = 180° - m∠bca

m∠abc = m∠bac + m∠bca

To find m∠abc, the measure of angle ABC, you can use the following expressions:

m∠abc = 180° - m∠bca (Angle Sum Property of a Triangle): This expression states that the sum of the measures of the angles in a triangle is always 180 degrees. By subtracting the measures of the other two angles from 180 degrees, you can find the measure of angle ABC.

m∠abc = m∠bac + m∠bca (Angle Addition Property): This expression states that the measure of an angle formed by two intersecting lines is equal to the sum of the measures of the adjacent angles. By adding the measures of angles BAC and BCA, you can find the measure of angle ABC.

The height of the fountain in Luke's drawing is 4 cm. The result is obtained by using the scale on Isabella and Luke's drawing.

A scale of 1 : n means that 1 unit in a drawing is equal to n unit in the real dimension. The formula is

1 : n = dimension in the drawing : dimension in real

If given

What is the height of the fountain in Luke's drawing?

First, we simplify the scale on Isabella's drawing.

The scale on Isabella's drawing is

= 3 cm : 6 m

= 3 cm : 600 cm

= 1 : 200

Then, we find the height of the fountain in real.

The real height

= dimension in the drawing × n

= 200 × 5

= 1.000 cm

The scale on Luke's drawing

= 2 cm : 5 m

= 2 cm : 500 m

= 1 : 250

The height in Luke's drawing is

= the height in real ÷ n

= 1.000 ÷ 250

= 4 cm

Hence, the height of the fountain in Luke's drawing is 4 cm.

In 53,721,360 ways can the sites for the new stores be selected.

A department store chain is expanding into a new market. It is considering 22 different sites on which to locate 6 stores. Let us assume  each site is equally likely to be chosen.

We can find number of ways by multiplying the amount of possibility each store can have.

The store 1, it can be placed on 22 sites. The Store 2 can be placed on 21 sites (since store 1 is already on site 1). The Store 3 can be placed on 20 sites. Store 4 which has 19sites. store 5 which has 18 sites. And  store 6 which has 17 sites.

Therefore the number of ways the sites for the new stores be selected is:

C = 22 × 21 × 20 × 219 × 18 × 17

C = 53,721,360 possibilities

Thus, the sites for the new stores be selected in 53,721,360 ways.

Answer:

\(n = 1230 - 30a\)

Step-by-step explanation:

Given

\(3a + 0.1n = 123\)

Required

Solve for n

\(3a + 0.1n = 123\)

Subtract 3a from both sides

\(3a - 3a + 0.1n = 123 - 3a\)

\(0.1n = 123 - 3a\)

Divide through by 0.1

\(n = \frac{123 - 3a}{0.1}\)

Split the fraction

\(n = \frac{123}{0.1} - \frac{3a}{0.1}\)

\(n = 1230 - 30a\)

The speed of the boat in still water is 12 miles per hour, and the speed of the current is 9 miles per hour.

To solve this problem, we can use the concept of relative speed and the formula: Distance = Speed x Time.

Let's denote the speed of the boat in still water as 's' (in miles per hour) and the speed of the current as 'c' (in miles per hour).

When the boat is traveling downstream (with the current), its effective speed is increased by the speed of the current. Therefore, the speed downstream is s + c.

Similarly, when the boat is traveling upstream (against the current), its effective speed is decreased by the speed of the current. Therefore, the speed upstream is s - c.

Given:

Distance downstream = 210 miles

Time downstream = 10 hours

Using the formula: Distance = Speed x Time, we can write the equation for the downstream journey as:

210 = (s + c) x 10

Simplifying the equation, we have:

21 = s + c

Similarly, for the upstream journey:

Distance upstream = 210 miles

Time upstream = 70 hours

The equation for the upstream journey becomes:

210 = (s - c) x 70

Simplifying:

3 = s - c

Now we have a system of equations:

21 = s + c

3 = s - c

We can solve this system of equations to find the values of 's' and 'c'. Adding the two equations together, we get:

24 = 2s

s = 12

Substituting the value of 's' back into either equation, we find:

3 = 12 - c

c = 9

Therefore, the speed of the boat in still water is 12 miles per hour, and the speed of the current is 9 miles per hour.
