The regular pay amount for the first week of July is $344
The overtime pay amount for the first week of July is $193.50
The gross pay amount for the first week of July is $537.50
How to find the earnings of sam?Total hours Sam worked = 55 hoursTotal regular hours = 40 hoursOvertime hours = Total hours Sam worked - Total regular hours
= 55 - 40
= 15 hours
Amount Sam earn per hour for regular hours = $8.60
Total regular pay amount = Total regular hours × Amount Sam earn per hour for regular hours
= 40 × $8.60
= $344
Amount Sam earn per hour for overtime hours = $8.60 × 1.5
= $12.90 per overtime hour
Total overtime pay amount = Overtime hours × Amount Sam earn per hour for overtime
= 15 × $12.90
= $193.50
Total gross pay = Total regular pay amount + Total overtime pay amount
= $344 + $193.50
= $537.50
In conclusion, the regular, overtime and gross pay of Sam for the first week of July is $344, $193.50 and $537.50 respectively.

The mapping diagram represents a relation where x represents the independent variable and y represents the dependent variable.
A mapping diagram with one circle labeled x-values containing values negative 4, negative 2, 0, 1, and 3 and another circle labeled y values containing values negative 5, negative 4, negative 3, negative 2, and negative 1 and arrows from negative 4 to negative 5, negative 2 to negative 3, 0 to negative 4, 0 to negative 2, 1 to negative 3, and 3 to negative 1.
Is the relation a function? Explain.
No, because for each input there is not exactly one output
No, because for each output there is not exactly one input
Yes, because for each input there is exactly one output
Yes, because for each output there is exactly one input
Answer:
This relation is not a function. For each input, there is not exactly one output.
The relationship in the given diagram is not a function, because for each input there is not exactly one output. So Option A is correct
What are functions?Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).
Vertical line test:-
Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.
If we get more images then it will not be a function.
For example, let us take, y² = 4ax
y = ±√4ax
For single value of x we get two values of y
Hence, it will not be a function.
Given that,
Values of x and values of y
In given diagram,
for x = 0,
there are two values of y, -4 and -2

identify the table that would correctly graph the equation y=3x
To be able to determine which table would correctly graph the equation y = 3x, let's one pair of data in the table and substitute it to the equation. The data that satisfies the equation is therefore the one that would correctly graph the equation.
We get,
A.) x = 0 and y = 2
y = 3x
2 = 3(0)
2 = 0
Therefore, this table will not correctly graph the equation.
B.) x = 0 and y = 4
y = 3x
4 = 3(0)
4 = 0
Therefore, this table will not correctly graph the equation.
C.) x = 0 and y = 1
y = 3x
1 = 3(0)
1 = 0
Therefore, this table will not correctly graph the equation.
D.) x = 0 and y = 0
y = 3x
0 = 3(0)
0 = 0
Therefore, this table will correctly graph the equation.
The answer is letter D.
I have a question where I need to graph a hyperbola equation and all I am given is the equation Picture included
Given
The equation of the hyperbola is:
[tex]\frac{y^2}{9}\text{ -x}^2\text{ = 1}[/tex]We can see that this is a vertical hyperbola since y is positive.
The general equation of a vertical hyperbola is:
[tex]\begin{gathered} \frac{(y-k)^2}{a^2}\text{ -}\frac{(x\text{ -h})^2}{b^2}=\text{ 1} \\ Where\text{ }(h,k)\text{ is the center} \end{gathered}[/tex]The steps to graph a hyperbola are:
1. Determine if it is horizontal or vertical. Find the center point, a, and b.
2. Graph the center point.
3. Use the a value to find the two vertices.
4. Use the b value to draw the guiding box and asymptotes.
5. Draw the hyperbola.
Step 1: This hyperbola is vertical
center point = (0,0)
Step 2: The values of a and b
[tex]\begin{gathered} a^2=\text{ 9} \\ a\text{ = 3} \\ b^2\text{ = 1} \\ b\text{ = 1} \end{gathered}[/tex]Step 3: Draw the guiding box:
Step 4: Draw the asymptotes
The asymptotes are diagonal lines through the corners of the box
Step 5: Finally, we draw in our hyperbola. Each half starts at the vertex and continues towards the asymptotes but never actually reaches them.
Step 6:
The center point, guiding box, and asymptotes are not technically part of the answer, so a clean version of the graph would look like this:
The graph of the hyperbola is shown below:

The perimeter of rectangle A is 10 cm
Perimeter of A = 2x+2y=10 cm, then:
Perimeter of A = 2(x+y)=10
Perimeter of A = x+y=5
We also know that the area of A= xy= 6 cm²
Then, we can admit x=3 and y=2.
Both rectangles are similar.

ANSWER:
2nd option: ΔABC ~ ΔEDC, because m<3 = m<4 and m<1 = m<5
STEP-BY-STEP EXPLANATION:
In order to answer the question we must take into account the difference between similarity and congruence.
We can see it in the following image:
That is, similar have the same figure but not the same size, while congruent have the same size and the same figure.
We can see that in this case the triangles are similar, we know this since angles 3 and 4 are equal because they share a vertex.
So the correct answer is the 2nd option: ΔABC ~ ΔEDC, because m<3 = m<4 and m<1 = m<5
