Step-by-step explanation:
Which statement could be used to explain why the function h(x) = x3 has an inverse relation that is also a function?
The graph of h(x) passes the vertical line test.
The graph of the inverse of h(x) is a vertical line.
The graph of the inverse of h(x) passes the horizontal line test.
The graph of h(x) passes the horizontal line test.
Answer:
The correct option is;
The graph of h(x) passes the horizontal line test
Step-by-step explanation:
In order to determine if a function has an inverse, and also if the inverse of the function is also a function, the function can be tested by drawing an horizontal line the graph of the function and viewing to find the following conditions;
A graph of a function that is intersected at only one point in all places (vertically) by an horizontal line indicates that the function has an inverse that is also a function, while a graph of a function that is intersected at more than one point in some places (vertically) by an horizontal line indicates that the function does not have an inverse that is also a function.

Using the Law of Detachment if a polynomial is prime, then it cannot be factored. 5x+13y is prime.
Answer and Step-by-step explanation: Law of deduction is a mathematical logic that states the following:
1) If p happens, then q happens;
2) p is true;
Then, a there is a third statement that is
3) q is also true.
In this question,
If a polynomial is prime, then it cannot be factored.
Statement p is that 5x + 13y is a polynomial and is prime, i.e., p is true.
Statement q is that "it cannot be factored"
Therefore, 5x + 13y cannot be factored.
The law of detachment is used to confirm or refute a claim.
The true statement is: 5x + 13y cannot be factored
The law of detachment states that; for statements p and q
(1) If p then q
(2) p
If the above statements are true, then the following statement is true
(3) q
The statements in the question can be represented as:
(1) If 5x + 3y is a polynomial and is prime then it cannot be factored
(2) It cannot be factored
Using the above representations of p and q, as an illustration; the third statement would be:
(3) 5x + 3y is a polynomial and is prime
Since the third statement is true, then we can conclude that
5x + 13y cannot be factored

1) Diego measured the number of cups of water in 15 bottles of various sizes. He
made this line plot to show how many of each size he has. Diego then took all
the bottles of the most common size and poured the water into one container.
How much water is in the container?
Bottle Sizes in Cups
Answer:
[tex] 8\frac{3}{4} [/tex] cups.
Step-by-step explanation:
From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).
If he poured all 5 of this bottle sizes in 1 container, he would have the following:
[tex] 1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4} [/tex]
[tex] = 8\frac{3}{4} [/tex] cups.

Find the approximate perimeter of rectangle ABCD plotted below.
B(4,5)
A(-6,0)
C(8, -3)
D(-2, -8)
Answer:
The answer is 40.2
The approximate perimeter of the rectangle ABCD plotted below is 40.24 units.
The given coordinates are B(4,5), A(-6,0), C(8, -3) and D(-2, -8).
We need to find the perimeter of the rectangle ABCD by plotting the coordinates on the graph.
What is the formula to find the perimeter of the rectangle?The formula to find the perimeter of the rectangle is 2(Length+Breadth).
By using the distance formula find the length and breadth of a rectangle.
That is Distance = [tex]\sqrt{(x_{2}-x_{1} )^{2} -(y_{2}-y_{1} )^{2}}[/tex] units.
Now, AB=[tex]\sqrt{(4+6)^{2}+(5-0)^{2} } =\sqrt{125}[/tex]=11.18 units
BC=[tex]\sqrt{(8-4)^{2}+(-3-5)^{2} } =\sqrt{80}[/tex]=8.94 units
Now, Perimeter=2(11.18+8.94)=40.24 units
Therefore, the approximate perimeter of the rectangle ABCD plotted below is 40.24 units.

PLEASE HELP I WILL MARK YOU BRAINLIEST THERE IS A PICTURE AT THE BOTTOM.
Answer:
72 sq. inches
Step-by-step explanation:
We are trying to find the area of the shaded part, and so we start with finding the area of the entire half that is marked (the area with measurements). The length is 8 in, as seen on the bottom, and the height is 12 in, as seen on the side. 8 * 12 = 96, so the entire portion from the shaded part to the very right is 96 sq. inches. Now we have to take out the white triangle part to find the area of the shaded part. Area of a triangle = 1/2*base * height, so we multiply 1/2 * 12 * 4, which gets us 24. Now that we know the area of the triangle, we subtract it from the previous area we got, which was the area of the shaded part plus the triangle (96). 96 - 24 = 72, so the area of the shaded portion is 72 sq. inches. Hope this helps!

11.) Sam has a total of 45 dimes and nickels. The number of dimes she has is 3 more than twice the number of nickels. How many of each coins does she have? How much money does she have altogether?
Answer:
Number of nickels: 14
Number of dimes: 31
Total money: $3.80
Step-by-step explanation:
Let number of nickels be x
Number of dimes is 2x+3
Total coins = 45
So add the number of nickels and dimes and it equals 45
x+2x+3=45
3x=45-3=42
x=42/3=14 nickels
Substitute the value of x=14 in 2x+3 to find number of dimes
2(14)+3=28+3=31 dimes
Total money is 14 nickels + 31 dimes
Nickels = 0.05 and dimes is 0.10
14(0.05)+31(0.10)=0.7+3.1=3.8
