The identity function on A, idA: A →A is defined by idA(a) = a.
1. (a) We defined a function as a relation with a particular property, thus
we can talk about properties of relations. Prove that if f : A →A
is reflexive, then f =idA.
(b) Prove that if f is symmetric then the function f^2 : A →A defined
by f^2(a) = f (f (a)) is the identity.
(c) Prove that if f is transitive then the function g : im(f) →im(f) given
by g(f (a)) = f (f (a)) is the identity on im(f) .
These are just sketches, you should polish them yourself. In analogy to relations, I will write aFb to mean the statement f(a) = b.
(a) aFa, so f(a) = a. This is the definition of the identity function.
(b) aFb => bFa, so f(a) = b and f(b) = a. Therefore f(f(a)) = a by substitution, and hence f^2 is the identity function.
(c) aFb and bFc => aFc. So f(f(a)) = c, and f(a) = c. Thus f(c) = c, which is the identity. Make sure you sort out the im(F) stuff when you clean this up.
Ms.Rodriguez will conduct a survey at her school about students and
how best to complete make-up work. She will select a random
sample of students at the school to take the survey. Which survey
method should she use?
Answer: Choice C
This is conducting a simple random sample (SRS) which is often the most effective way to form a sample. The other methods have some kind of bias to them, which means the sample won't represent the population.
If a coin is tossed 4 times, and then a standard six-sided die is rolled 4 times, and finally a group of three cards are drawn from a standard deck of 52 cards without replacement, how many different outcomes are possible?
Answer:
89,820,057,600.
Step-by-step explanation:
For the number of ways 5 cards can be taken from a standard 52 card deck, there are 52 choices for the first card. After the first card is chosen, there are 51 choices remaining for the second card. Following this pattern, you will the total number of ways the 5 cards can be chosen being 52 x 51 x 50 x 49 x 48 = 311,875,200. Or, you can also use the permutation of 52 cards taken 5 at a time which is 52!/(52 – 5)! = 311,875,200.
Hence, the total number of outcomes for all the above is 8 x 36 x 311,875,200 = 89,820,057,600.

8
Answer:
x = -8, x = 8
Step-by-step explanation:
|x| = 8
The absolute value turns the negative value inside the positive.
When given an absolute value like this, there are two cases.
If the absolute value is equal to something greater than 0, it has two solutions. If less than 0, it has no solutions. If it is equal to 0 it has 1 solution.
Since 8 is greater than 0, there are two solutions.
On solution is the positive version, one is the negative
So:
|x| = 8x = 8, x = -8-Chetan K
Solution:
Note that:
Given equation: IxI = 8If a question is saying to find the absolute value of a number, that number will always result in positive.This can lead to two solutions:
IxI = 8 ⇒ x = 8IxI = 8 ⇒ x = -8What is the perimeter of the triangle?

What is a triangle?A triangle is a polygon with 3 sides.
Given the quadrilateral ABCD.
The sum of the interior angles of a triangle is 180°, therefore,
44° + 38° + m∠C = 180°
m∠C = 180° - 44° - 38°
m∠C = 98°
Now, using the sine law in triangle BDC, it follows:
sin44°/ BC = sin98°/10
BC = (10·sin44°)/ sin98°
BC ≈ 7
The area of a triangle is half the product of its two sides and the sine of the included angle, therefore, the area of triangle BDC is:
A₁ = (1/2)× 10×7× sin38°
A₁ = 21.5
Now, in triangle ABD,
cos55° = AD/10
AD = 10 cos55°
Similarly,
sin55° = AB/10
AB = 10sin 55°
Hence, the area of the triangle ABD is:
A₂ = (1/2) × (10 cos55°) ×(10sin 55°)
A₂ = 23.5
Therefore, the total area of the figure is:
A = A₁ + A₂
A = 21.5 + 23.5
A = 45.0
Hence, the area of the figure is about 45 square cm.

Given the triangle ABC with points:
A - (1, 3)
B - (-2, 2)
C - (4, 0)
Rotate ABC 180 degrees clockwise about the origin and then translate the resulting triangle five units down. Determine the ordered pairs for A', B', and C'.
Rotating and translating the triangle are illustrations of transformations
The ordered pairs for A', B' and C' are (-1, -8), (2, -7) and (-4, -5)
How to transform the triangleThe coordinates of the pre-image of the triangle are:
A = (1, 3)
B = (-2, 2)
C = (4, 0)
When the triangle is rotated 180 degrees, the rule of transformation is:
(x,y)→(−x,−y)
So, we have:
A' = (-1, -3)
B' = (2, -2)
C' = (-4, 0)
When the triangle is translated 5 units down, the rule is:
(x,y)→(x,y-5)
So, we have:
A' = (-1, -8)
B' = (2, -7)
C' = (-4, -5)
Hence, the ordered pairs for A', B' and C' are (-1, -8), (2, -7) and (-4, -5)

4. Cindy is designing a rectangular fountain in the middle of a courtyard. The rest of the courtyard will be covered in stone. The part of the courtyard that will be covered in stone has an area of 246 square feet. Show your work. b. What fraction of the courtyard will be occupied by the fountain?
Answer:
12 x 22 = 264 so that would be 264 - 246 = 18
The answer is 18 square feet.
Step-by-step explanation:
You'll need to simplify 18/264, then divide that number into 18/264 such as 18/264 divided by 2/2 or 3/3.

What is the area of a triangle with vertices at (−4, −6), (1, −6), and (1, 2)?
Answer:
20
Step-by-step explanation:
firstly let's find out the side lengths of the triangle using formula
[tex]length \: = \: \sqrt{(y₂-y1) + ( y₂-y1)}[/tex]
length of AB
[tex] \sqrt{( - 6 - 2) {}^{2} + ( - 4 - 1) {}^{2} } = \sqrt{89} [/tex]
length of AC
[tex] \sqrt{( - 6 - 2) {}^{2} + (1 - 1) {}^{2} } = 8[/tex]
length of BC
[tex] \sqrt{( - 6 - ( - 6)) {}^{2} + (1 - ( - 4)) {}^{2} } = 5[/tex]
Now we have all three side lengths:
a =√89 b = 8 and c = 5
using this formula to find the semi perimeter where a, b and c are the side lengths, input them in
[tex]s \: = \: \frac{a + b + c}{2} [/tex]
[tex]s = \frac{ \sqrt{89} + 8 + 5 }{2} = \frac{13 + \sqrt{89} } {2} [/tex]
Use heron's formula
[tex]area = \sqrt{s(s - a)(s - b)(s - c)} [/tex]
[tex]area = \sqrt{ \frac{13 + \sqrt{89} }{2}(\frac{13 + \sqrt{89} }{2} - \sqrt{89})( \frac{13 + \sqrt{89} }{2} - 8)(\frac{13 + \sqrt{89} }{2} - 5 } = 20[/tex]
area = 20

Last year, Jose opened an investment account with $6600. At the end of the year, the amount in the account had decreased by 28.5%. How much is this decrease in dollars? How much money was in his account at the end of last year?
Answer:
decrease: $1881ending value: $4719Step-by-step explanation:
The decrease is found by multiplying the original amount by the percentage decrease:
$6600 × 28.5% = $6600 × 0.285 = $1881
Jose's account decreased by $1881.
__
The remaining value is the original amount, less the amount of decrease.
$6600 -1881 = $4719
At the end of last year, Jose had $4719 in his investment account.

Let x = unknown number
