Answer:

6. see attached

7. (a, b) = (-2, 3)

8. equation has issues

Step-by-step explanation:

6. Matrix addition is defined for corresponding terms, so the usual associative and commutative properties of addition apply. That is, ...

A₁₁ +B₁₁ = (A+B)₁₁ . . . . . and the same for other corresponding terms

The attachment shows the sums are equal. (It is convenient to let a spreadsheet do the tedious repetitive work.)

7. To find 'a' and 'b', we only need to consider the matrix elements that involve those variables.

element 11: 5 = b +2 ⇒ b = 3

element 21: a = 2 +2a ⇒ a = -2 (add -a-2 to both sides to get this)

8. There are issues with this equation. It is incomplete and inconsistent.

element 11: p = p+4 ⇒ no solution

element 21: r = 0 +(2r s) ⇔ missing math symbol; problem is incomplete

element 12: q = 6 + (p +q) ⇒ p = -6; q = anything

element 22: s = 2s +2 ⇒ s = -2 (add -s-2 to both sides)

Additional comment

When a problem has issues of the kind that show up in question 8, I suggest that you have your teacher show you how to work the problem. If they're paying attention, they will discover the issues for themselves.

If they are able to work the problem, it will be because they filled in the missing information and resolved the inconsistencies. This will let you see the intended question.

Which of the following decimals is equal to 3 1/40 ? Select TWO that apply

A 3.0025
B 3.025
С 3. overline 0025
D 3.overline 025
E 3.0025 overline0
F. 3.025overline0

Answers

Answers: Choice B, Choice F

=======================================================

Explanation:

Use long division or your calculator to find that 1/40 = 0.025

Add on 3 to get 3 & 1/40 = 3 + 1/40 = 3 + 0.025 = 3.025 which is choice B

For some reason, your teacher has decided to add on a string of 0's onto this to form [tex]3.025\overline{0}[/tex] that horizontal line over the '0' means the 0's go on forever. So, [tex]3.025 = 3.025\overline{0} = 3.025000000...[/tex], but we can always chop off the trailing zeros to make life simpler. I'm not sure why your teacher has decided to use this fairly strange format.

The decimal value is equivalent to 3.025.

What are decimal numbers?A decimal is a number that consists of a whole and a fractional part. Decimal numbers lie between integers and represent numerical value for quantities that are whole plus some part of a whole.

We have the following fraction -

3 [tex]\frac{1}{40\\}[/tex]

We can write the mixed fraction as -

3 [tex]\frac{1}{40\\}[/tex]

(40 x 3 + 1)/40

121/40

3.025

Therefore, the decimal value is equivalent to 3.025.

Graph the polygon and its image after a dilation centered at C(1,1)
with scale factor k=0.5
.

J(3,1), K(5,−3), L(5,5), M(3,7)

Answers

Now we proceed to present the graphs of the polygon and its image with the help of a graphing tool. The original polygon is highlighted in red and the image is highlighted in blue.

DIlations are defined by the follwing operation:

[tex]P'(x,y) = O(x,y) + k\cdot [P(x,y)-O(x,y)][/tex] (1)

Where:

[tex]O(x,y)[/tex] - Center of dilation.[tex]k[/tex] - Dilation factor.[tex]P(x,y)[/tex] - Original point of the polygon.[tex]P'(x,y)[/tex] - Dilated point of the polygon.

If we know that [tex]O(x,y) = (1,1)[/tex], [tex]k = 0.5[/tex], [tex]J(x,y) = (3,1)[/tex], [tex]K(x,y) = (5, -3)[/tex], [tex]L(x,y) = (5,5)[/tex] and [tex]M(x,y) = (3,7)[/tex], then the coordinates of the new polygon are:

[tex]J'(x,y) = (1,1) + 0.5\cdot [(3,1)-(1,1)][/tex]

[tex]J'(x,y) = (1,1)+0.5\cdot (2,0)[/tex]

[tex]J'(x,y) = (1,1) +(1,0)[/tex]

[tex]J'(x,y) = (2,1)[/tex]

[tex]K'(x,y) = (1,1) + 0.5\cdot [(5,-3)-(1,1)][/tex]

[tex]K'(x,y) = (1,1) +0.5\cdot (4,-4)[/tex]

[tex]K'(x,y) = (1,1) +(2,-2)[/tex]

[tex]K'(x,y) = (3,-1)[/tex]

[tex]L'(x,y) = (1,1) + 0.5\cdot [(5,5)-(1,1)][/tex]

[tex]L'(x,y) = (1,1) + 0.5\cdot (4,4)[/tex]

[tex]L'(x,y) = (1,1) + (2,2)[/tex]

[tex]L'(x,y) = (3,3)[/tex]

[tex]M'(x,y) = (1,1) + 0.5\cdot [(3,7)-(1,1)][/tex]

[tex]M'(x,y) = (1,1) +0.5\cdot (2,6)[/tex]

[tex]M'(x,y) = (1,1) +(1,3)[/tex]

[tex]M'(x,y) = (2,4)[/tex]
