How do you work at where the straight lines are going to be?

The difference quotient for the given function is 9 -2/h.

The difference quotient for the given function can be calculated as:

[f(x+h) - f(x)]/h

= [(3(x+h)² - 2(x+h) + 5) - (3x² - 2x + 5)]/h

= (3x² + 6xh + 3h² - 2x - 2h + 5 - 3x² + 2x - 5)/h

= (6xh + 3h² - 2h)/h

= (6x + 3h -2)/h

Simplifying the expression further, we get:

(6x + 3h -2)/h = 6 + 3h/h -2/h

= 6 + 3 -2/h

= 9-2/h

Therefore, the difference quotient for the given function is 9 -2/h.

Answer:

The expression (8-i)/(2+i) in standard form is, 3 - 2i

Step-by-step explanation:

The expression is,

(8-i)/(2+i)

writing in standard form,

\((8-i)/(2+i)\\\)

Multiplying and dividing by 2+i,

\(((8-i)/(2+i))(2-i)/(2-i)\\(8-i)(2-i)/((2+i)(2-i))\\(16-8i-2i-1)/(4-2i+2i+1)\\(15-10i)/5\\5(3-2i)/5\\=3-2i\)

Hence we get, in standard form, 3 - 2i

The expression (8-i)/(2+i) in standard form a+bi is (15 - 10i) / (3 + 4i).

To write the expression (8-i)/(2+i) in standard form a+bi, we need to eliminate the imaginary denominator. We can do this by multiplying the numerator and denominator by the conjugate of the denominator.

The conjugate of 2+i is 2-i. So, we multiply the numerator and denominator by 2-i:

(8-i)/(2+i) * (2-i)/(2-i)

Using the distributive property, we can expand the numerator and denominator:

(8(2) + 8(-i) - i(2) - i(-i)) / (2(2) + 2(i) + i(2) + i(i))

Simplifying further:

(16 - 8i - 2i + i^2) / (4 + 2i + 2i + i^2)

Since i^2 is equal to -1, we can substitute -1 for i^2:

(16 - 8i - 2i + (-1)) / (4 + 2i + 2i + (-1))

Combining like terms:

(15 - 10i) / (3 + 4i)

Therefore, the expression (8-i)/(2+i) in standard form a+bi is (15 - 10i) / (3 + 4i).

The diameter of the circle is 12.5 inches

The circumference (or) perimeter of a circle = 2πr units. The area of a circle = πr2 square units. Where r is the radius of the circle. The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by the circle.

Given here: 157 breaks required to make a circular garden and cover the boundary.

Now each brick is 4 inches long

Thus total length of the circumference of the circular garden we get

157/4=39.25 inches long

Thus the circumference of the circle is given by

Answer:

The area of the triangle is 70.805 ft squared

Step-by-step explanation:

The parcel is 30 acres in size, calculated as 10 acres for the NW 1/4 of the SE 1/4 and 20 acres for the S 1/2 of the SW 1/4 of the NE 1/4.

To solve the problem, we need to know the size of the quarter sections that are being referred to. In the United States, a quarter section is 160 acres.

Using this information, we can break down the given parcel as follows:

NW 1/4 of the SE 1/4: This represents 1/16 of a section, or 10 acres (160 acres / 16 * 1 = 10).

S 1/2 of the SW 1/4 of the NE 1/4: This represents 1/8 of a section, or 20 acres (160 acres / 8 * 1/2 = 20).

To find the total size of the parcel, we simply add these two areas together:

(10 + 20 )acres = 30 acres

Therefore, the parcel is 30 acres in size.

In the United States, a section of land is a unit of area measurement used in land surveys, and it is equal to 640 acres. A quarter section is, therefore, one-fourth of a section, or 160 acres.

The given parcel is described as two parts. The first part is the northwest quarter of the southeast quarter, which is equivalent to one-sixteenth of a section or 10 acres (1/4 x 1/4 x 160 acres = 10 acres).

The second part is the south half of the southwest quarter of the northeast quarter, which is equivalent to one-eighth of a section or 20 acres (1/4 x 1/4 x 1/2 x 160 acres = 20 acres).

To find the total size of the parcel, we add the area of the two parts: 10 acres + 20 acres = 30 acres. Therefore, the parcel is 30 acres in size.

3.1. No, {b} is not necessarily in the Sigma Algebra if {a} is.

3.2. No, {c} is not necessarily in the Sigma Algebra if {a} and {b} are.

In the context of the sample space S = {a, b, c, d} and the Sigma Algebra, we cannot conclude that {b} is necessarily in the Sigma Algebra if {a} is. Similarly, we cannot conclude that {c} is necessarily in the Sigma Algebra if both {a} and {b} are.

A Sigma Algebra, also known as a sigma-field or a Borel field, is a collection of subsets of the sample space that satisfies certain properties. It must contain the sample space itself, be closed under complementation (if A is in the Sigma Algebra, its complement must also be in the Sigma Algebra), and be closed under countable unions (if A1, A2, A3, ... are in the Sigma Algebra, their union must also be in the Sigma Algebra).

In 3.1, if {a} is in the Sigma Algebra, it means that the set {a} and its complement are both in the Sigma Algebra. However, this does not guarantee that {b} is in the Sigma Algebra because {b} may or may not satisfy the properties required for a set to be in the Sigma Algebra.

Similarly, in 3.2, even if {a} and {b} are both in the Sigma Algebra, it does not necessarily imply that {c} is also in the Sigma Algebra. Each set must individually satisfy the properties of the Sigma Algebra, and the presence of {a} and {b} alone does not determine whether {c} meets those requirements.

Minors and Cofactors of the matrix are found through these steps:Step 1: Find the determinants of 2 × 2 matricesStep 2: Create a matrix of cofactorsStep 3: Transpose the matrixStep 4: Multiply the 1/determinant by the transposed matrix (adjugate) to get the inverse.Step 1: Find the determinant of the matrix to get the minors of the matrix:

\(\[\left| \begin{matrix}-2 & 1 & 3\\6 & 4 & 5\\3 & -2 & 1\end{matrix}\right| = -2 \left| \begin{matrix}4 & 5\\-2 & 1\end{matrix}\right| -1 \left| \begin{matrix}6 & 5\\3 & 1\end{matrix}\right| + 3 \left| \begin{matrix}6 & 4\\3 & -2\end{matrix}\right|\] \[\left| \begin{matrix}-2 & 1 & 3\\6 & 4 & 5\\3 & -2 & 1\end{matrix}\right| = -2 (4-(-10)) -1(6-15) +3(-12-10) = -2 (14) +1(9) -3(22) = -96\]\)

Therefore:

\(M11 = -96, M12 = -49, M13 = 22, M21 = 22, M22 = 7, M23 = -14, M31 = 4, M32 = -5, M33 = 14\)

Step 2: Creating a matrix of cofactors, we have

\(\[\left[ \begin{matrix}M_{11}&-M_{12}&M_{13}\\-M_{21}&M_{22}&-M_{23}\\M_{31}&-M_{32}&M_{33}\end{matrix}\right]\] \[\left[ \begin{matrix}-96&49&22\\-22&7&14\\4&5&14\end{matrix}\right]\]\)

Step 3: Transpose the matrix to

\(\[\left[ \begin{matrix}-96&-22&4\\49&7&5\\22&14&14\end{matrix}\right]\]\)

Step 4:  Multiply the 1/determinant by the transposed matrix (adjugate) to get the inverse.

\(\[\frac{1}{-96} \left[ \begin{matrix}-96&-22&4\\49&7&5\\22&14&14\end{matrix}\right] = \left[ \begin{matrix}\frac{1}{24}&\frac{11}{96}&-\frac{1}{24}\\\frac{-49}{96}&\frac{-7}{96}&\frac{5}{24}\\-\frac{11}{48}&\frac{-7}{48}&\frac{7}{48}\end{matrix}\right]\]\)

Therefore, the minors of the matrix are M11 = -96, M12 = -49, M13 = 22, M21 = 22, M22 = 7, M23 = -14, M31 = 4, M32 = -5, M33 = 14. The cofactors are shown in the cofactor matrix, and the transpose of the cofactor matrix is the adjugate matrix.

Answer:

To find the tens and units digit of the product, we only need to focus on the last two digits of the product.

First, we multiply 8 x 6, which gives us 48. So the units digit is 8 and we carry-over the 4 to the tens digit.

Next, we multiply 7 x 6, which gives us 42. We add the carry-over 4, which gives us 46. So the tens digit is 6 and we carry-over the 4.

Continuing with the multiplication, we get:

6 x 0 = 0 (no carry-over)

6 x 7 = 42 (carry-over 4)

6 x 2 = 12 (carry-over 1)

Adding the carry-over, we get:

4 + 4 + 1 = 9

Therefore, x+y= 8 + 6 = 14
