Barb is making a bead necklace. She strings 1 white bead, then 3 blue beads, then 1 white bead and so on. Write the numbers for the first eight beads that are white. What is a rule for the pattern?
Answers
In Barb's necklace pattern, white beads occur at position numbers 1, 5, 9, 13, 17, 21, 25, and 29. The rule for the pattern is that any white bead will appear at a position that is 4n + 1, where n is any non-negative integer.
Explanation:The student's question involves determining the position numbers of the first eight white beads in a pattern and identifying a rule for this pattern. The pattern established by Barb is one white bead followed by three blue beads, which then repeats. To find the positions of the first eight white beads, let's enumerate the pattern until we have identified eight white beads.
WhiteBlueBlueBlueWhiteBlueBlueBlueWhite...As we can see, the white beads appear in a consistent pattern at every fourth position in the sequence. Thus, by listing out the pattern, we can identify the first eight white beads' position numbers as follows:
1591317212529The rule for the pattern can be described as follows: any white bead will be at a position number that is 1 more than a multiple of 4 (i.e., 4n + 1, where n is a non-negative integer).
The first eight white beads in Barb's necklace pattern are in positions 1, 5, 9, 13, 17, 21, 25, and 29. The rule for the pattern is 4n - 3 for the nth white bead.
Explanation:Barb is making a bead necklace with a repeating pattern: 1 white bead, followed by 3 blue beads, and then the pattern repeats. To determine the numbers for the first eight beads that are white, we can examine the pattern more closely. Since the pattern begins with a white bead and every white bead is followed by three blue beads, we can deduce that it takes 4 beads in total to complete one cycle of the pattern (1 white + 3 blue).
The positions of the first eight white beads are as follows: 1st, 5th, 9th, 13th, 17th, 21st, 25th, and 29th. The rule for this pattern can be expressed as follows: To find the position of any white bead in the sequence, you can use the formula 4n - 3, where n represents the nth white bead in the sequence.
For example, to find the position of the third white bead, we substitute n with 3 into our formula: 4 * 3 - 3, which equals 9. Therefore, the third white bead is the 9th bead in the overall pattern.

Hannah has 11 toothpicks that are the same length.Name the types of triangles and quadrilaterals Hannah can make if she uses only one toothpick for each side of each figure
Answers
Answer:
Step-by-step explanation:
Given that Hannah has 11 toothpicks that are the same length
When she uses only one toothpick for each side then we see that all sides would be equal whether quadrilateral or triangle.
Hence she can make equilateral triangles, rhombuses or squares out of these 11 toothpicks
Either one equilateral triangle, and 2 rhombuses, or one equil. triangle and 2 squares or 1 equil triangle with 1 square, 1 rhombus or 2 equil triangles with one square or rhombus

Find the average rate of change between n = 2 and n = 4.
Answers
The average rate of change of the sequence from n = 2 to n = 4 is 1.5, which is determined by calculating the difference in sequence values for these n values and dividing by the difference in n.
The average rate of change of a function between two points reflects the function's slope between those points. To find the average rate of change of the sequence [tex]a_n = \frac{1}{2} (2)^{n - 1}[/tex]from n = 2 to n = 4, we calculate the differences in the sequence values corresponding to these n values and divide by the difference in n itself.
The value of a_n when n = 2 is [tex]a_2 = \frac{1}{2} (2)^{2 - 1}= 1.[/tex]The value of a_n when n = 4 is [tex]a_4 = \frac{1}{2} (2)^{4 - 1}[/tex]= 4.To find the average rate of change, use the formula: rate of change = [tex](a_4 - a_2)[/tex] / (4 - 2) = (4 - 1) / (4 - 2) = 3/2 = 1.5.Therefore, the average rate of change between n = 2 and n = 4 for this sequence is 1.5.

Curtis build a dog house with base shaped like a cube and a roof shaped like a pyramid. The cube has an edge lenght of 3 1/2 feet. The height of the pyramid is 5 feet. Find the volume of the doghouse rounded to the nearest tenth.
Answers
V1 = L ^ 3
Where,
L: length of the sides of the cube.
Substituting we have:
V1 = (3 + 1/2) ^ 3
V1 = 42,875 feet ^ 3
The volume of the pyramid is:
V2 = ((Ab) * (h)) / (3)
Where,
Ab: base area
h: height
Substituting we have:
V2 = (((3 1/2) * (3 1/2)) * (5)) / (3)
V2 = 20.41666667 feet ^ 3
The volume of the house is the sum of both volumes:
V1 + V2 = 42,875 feet ^ 3 + 20.41666667 feet ^ 3
V1 + V2 = 63.29166667 feet ^ 3
Nearest tenth:
V1 + V2 = 63.3 feet ^ 3
Answer:

Write an equation of the line that is perpendicular to y = −4x + 8 and passes through the point (5, 1)
Answers
To start, we have to identify the slope of the perpendicular line. Perpendicular lines have opposite reciprocal slopes. Therefore, the slope of our new line will be 1/4.
Now, just substitute in the given point with our new slope and we can solve for B.
y = (1/4)x + b
1 = (1/4)5 + b
1 = 5/4 + b
-1/4 = b
Now that we have the slope and the y-intercept, we can put together our equation.
It is: y = (1/4)x - 1/4

How do you tell a triangle is not a right triangle
Answers
So a right triangle is classified as a right triangle because it has one right angle. You can tell if it's not a right triangle by the angle measurements. If all the angles are above or below 90 degrees, it's not a right triangle. If one of the angles is 90 degrees, it's classified as a right triangle.

The graph show is
A)fails the vertical line test at (2,3) and (2,-2)
B) fails the vertical line test at (2,3) and (-1,3)
C) passes the vertical line test
So the line is
A) a function
B) not a function
Answers
A)fails the vertical line test at (2,3) and (2,-2)
Second Answer:
B) not a function
=========================================
Further Explanation:
It is possible to pass a single vertical line through this red curve. So it is not a function because it fails the vertical line test. One specific line goes from (2,3) to (2,-2) but there are infinitely other lines to choose from. In order to pass the vertical line test, it must be impossible to pass a vertical line through more than one point on the curve. A function is where any given input leads to exactly one output. In the case of (2,3) and (2,-2), the input x = 2 leads to more than one output (y = 3 and y = -2) at the same time
