Step-by-step explanation: IT'S NOT A OR D.. ig
1: Recall that a function from a set to a set is a relation that assigns to each element in the set exactly one element in the set . The set is the domain (or set of inputs) of the function and the set contains the range (or set of outputs).
The general characteristics of functions are:
A. Each element in A must be matched with an element in B.
B. Some elements in B may not be matched with any element in A.
C. Two or more elements in A may be matched with the same element in B.
D. An element in A (the domain) can not be matched with two different elements in B.
________________________________________________
Solving this problem we have:
1. The mapping diagram is represented in Figure 1. As you can see this is a function. Each element in A is matched with an element in B. All the elements in A are matched with the same element in B. So, this fulfills with the definition of function.
2. The mapping diagram is represented in Figure 2. This is not a function. Notice that an element in A (the domain) is matched with two different elements in B, that is, -8 is matched with -6 and 1.
2: #1) This is a function.
#2) This is not a function.
(The mapping diagrams are not present to match to these.)
Explanation:
A function is a relation in which each element of the domain is matched to no more than one element of the range; in other words, no x gets mapped to more than 1 y.
In #1, no x is mapped to more than 1 y, so it is a function. However, in #2, -8 is mapped to both -6 and to 1; this x is used more than once, so this is not a function.

4: Answer:
Option D is correct.
The relation {(-8, -6) (-5, 2) (-8, 1) (7, 3)} is not a function.
Step-by-step explanation:
Given the relation: {(-8, -6) (-5, 2) (-8, 1) (7, 3)}
Domain is the set of all possible inputs of a relation i.e { -8, -5 , -8 , 7}
Range is the set of output values of a function i.e, {-6, 2 , 1 , 3}
The mapping as shown below in the figure:
A function is a relation in which every element of the domain is matched to not more than one element of the range.
In other words, we can say that ,no value of x gets mapped to more than 1 value of y.
Since, from the mapping you can see that the domain value -8 paired with -6 and 1; as x is used more than once.
Therefore, this relation is not a function

Step-by-step explanation:
Sum , 1 + 5/12 = (12 + 5) / 12

find the measure of all of the angles on the diagram
Answers
Answer:
Angle 1: 135*
Angle 2: 45*
Angle 3: 45*
Angle 4: 135*
Angle 5: 135*
Angle 6: 45*
Angle 7: 45*
Angle 8: 135*
Step-by-step explanation:
So we have angle 2, 45*, we can subtract 45 from 180 to get the angle for 1. Since everything is the same size as either 1 or 2 we can just plug in the bigger angle number we have for it, ex 4= 135 and so is 7.
If you don't understand something please don't hesitate to ask.
Answer:
Step-by-step explanation:
∠2 = 45
∠3 = ∠2 {Vertically opposite angles}
∠3 = 45
∠7 = ∠3 {Corresponding angles}
∠7 = ∠45
∠6 = ∠7 {Vertically opposite angles}
∠6 = 45
∠1 + ∠2 = 180 {Linear pair}
∠1 + 45 = 180
∠1 = 180 -45
∠1 = 135
∠4 =∠1 {Vertically opposite angles}
∠4 = 135
∠8 = ∠4 {Corresponding angles}
∠8 = 145
∠5 = ∠4 {Alternate interior angles}
∠5 = 145

Step-by-step explanation:
Side length of the square is also the diameter of the semicircle so:
r = 0.5 * 12 m = 6 m
Since you want the area of the shaded area, you have to subtract the area of both semi circles from the area of the square:
Square Area - Semi Circle Area - Semi Circle Area = Shaded Region Area
(12 m * 12 m) - (0.5 * 3.14 * 6^2 m) - (0.5 * 3.14 * 6^2 m)
= 144 - 56.52 - 56.52
= 30.96 m^2

x=a+b+4 and a is inversely proportional to y²; b is inverseley propotional to 1/y. when y = 2 x = 18 and when y = 1 x = -3. find x when y = 4
Answers
Answer:
When y = 4, x is equal to 39
Step-by-step explanation:
The given parameters are;
x = a + b + 4
a ∝ 1/y²
b ∝ 1/(1/y) = y
When y = 2, x = 18
When y = 1, x = -3
Therefore, we have;
a·y² = j
a = j/y²
b ∝ 1/(1/y)
∴ b ∝ y
b = k·y
When y = 2, x = 18, we have;
a = j/y² = j/2² = j/4
b = k·y = k·2
x = a + b + 4
∴ 18 = j/4 + k·2 + 4...(1)
When y = 1, x = -3, we have;
a = j/y² = j/1² = j
b = k·y = k·1 = k
x = a + b + 4
∴ -3 = j + k + 4...(2)
Making 'j', the subject of equation (1) and (2) gives;
From equation (1), we have;
18 = j/4 + k·2 + 4
∴ j = (18 - 4 - k·2) × 4 = 56 - 8·k
From equation (2), we have;
-3 = j + k + 4
∴ j = -3 - 4 - k = -7 - k
Equating the two values of 'j', gives;
56 - 8·k = -7 - k
56 + 7 = 8·k - k
63 = 7·k
k = 63/7 = 9
k = 9
From equation (2), we get;
-3 = j + k + 4
k = 9
∴ -3 = j + 9 + 4
j = -3 - 9 - 4 = -16
j = -16
When y = 4, we get;
x = a + b + 4
a = j/y²
b = k·y
∴ x = j/y² + k·y + 4
Plugging in the values of 'j', and 'k' and y = 4, gives;
x = (-16)/y² + 9·y + 4
∴ x = (-16)/4² + 9 × 4 + 4 = 39
x = 39
Therefore;
When y = 4, x = 39.
