Kylie swam 6 feet below sea level and Bryan swam 8 feet below sea level. Find the difference between the absolute values for each depth.
The difference between the absolute values of Kylie's and Bryan's depth is 2 feet.
Here, we are given that Kylie swam 6 feet below the sea level and Bryan swam 8 feet below sea level.
This implies,
Kylie's distance from the ground level = -6 feet
and Bryan's distance from the ground level = -8 feet
We need to find the difference between the absolute values of their depth.
Thus, we ignore the minus (-) sign and find the difference as follows-absolute difference = | 6 - 8 |
difference = 2 feet
Thus, the difference between the absolute values of their depth comes out to be 2 feet.

The probability that the break will occur within 20 meters of a pole is 12.5%.
Probability:
The term probability refers the possible occurrence of the required event.
Given,
A 320 meter long tightrope is suspended between two poles.
Here we assume that the line has an equal chance of breaking anywhere along its length.
Now, we need to determine the probability that the break will occur within 20 meters of a pole.
From the given question,
The line has an equal chance of breaking anywhere along its length.
The first and last 20meters form,
=> [ (20 + 20) / 320 ] x 100
=> [ 40 / 320 ] x 100

Karen is planning a graduation party for the senior class. She plans to rent a meeting room at the convention center that costs 400 . There is an additional fee of 5.50 for each person who attends the party.
d. If the senior class has raised 2000 for the party, how many people can attend?
Approximately 291 people can attend the party.
Given,
The rent of the meeting room at the convention center = 400
Additional fee for each person who attends the party = 5.50
The amount raised by the senior class for the party = 2000
Now we have to find the number of people can attend the party.
That is,
Amount raised by seniors – rent of meeting room = 2000 – 400 = 1600
Now,
The number of people can attend the party = (Amount raised by seniors – rent of meeting room) / additional fee for each person
= 1600 / 5.50
= 290.91

what value of x makes this equation true 1/5(2x-10)+4x=-3(1/5x+4)
For the equation 1 / 5 (2 x - 10) + 4 x = - 3 (1 / 5 x + 4), we get the value of x as - 2.
We are given the equation that:
1 / 5 (2 x - 10) + 4 x = - 3 (1 / 5 x + 4)
We need to solve the equation to find the value of x.
First, we will open the brackets in the equation:
2 / 5 x - 2 + 4 x = - 3 / 5 x - 12
Combining the like terms, we get that:
22 / 5 x - 2 = - 3 / 5 x - 12
Add 2 and 3 / 5 x to both the sides, we get that:
22 / 5 x - 2 + 2 + 3 / 5 x = - 3 / 5 x - 12 + 2 + 3 / 5 x
5 x = - 10
Divide both the sides by 5, we get that:
5 x / 5 = - 10 / 5
x = - 2
Therefore, for the equation 1 / 5 (2 x - 10) + 4 x = - 3 (1 / 5 x + 4), we get the value of x as - 2.

Write the function rule for each function reflected in the given axis.
f(x)=2 x-6 ; y -axis
Functions can be reflected on the x-axis, the y-axis, or both axes. For example, function reflection y= f(x) can be written as y= -f(x) or y= f(-x) even y= -f(-x). There are four types of function or graph transformations: reflection, rotation, translation, and dilation. In mathematics, especially geometry, mirror or mirroring means flipping, so basically, the mirroring of a function is the mirror image of a given function or graph. Hence the reflection function is commonly known as the reflection function.
The function's reflection should be similar in size and shape to the original function.

Determine whether each sequence is arithmetic, geometric, or neither. Then find the tenth term. 1/4, 1,4,16,. . . .
The sequence 1/4, 1, 4, 16, . . . . is a geometric sequence and its 10th term is 65,536
To determine whether the sequence is an arithmetic or geometric one, we need to check the relation between two consecutive terms.
If it is an arithmetic sequence, then:
a(n) = a(n-1) + d
where d is the common difference.
If it is a geometric sequence, then:
a(n) = a(n-1) . r
where r is the common ratio.
The given sequence is:
1/4, 1, 4, 16, . . . .
In this sequence:
a(1) = 1/4
a(2) = 1
a(3) = 4
a(4) = 16
Notice that
a(2) : a(1) = 1 : 1/4 = 4
a(3) : a(2) = 4 : 1 = 4
and so on
Since the ratio of consecutive terms are constant, then the given sequence is a geometric sequence. Furthermore, its ratio, r = 4.
To find the 10th term, use the formula:
a(n) = a(1) . rⁿ⁻¹
Substitute n = 10, r = 4, and a(1) = 1/4
a(10) = 1/4 . 4⁹
a(10) = 4⁸ = 65,536

b. If you know the 5th and 6th terms of an arithmetic sequence, how can you find term 7 using the arithmetic mean?
The 7th term of the Arithmetic Progression (AP) is found using the common difference formula.
What is the sequence of AP arithmetic progression?In Arithmetic Progression, the difference between the two arithmetical orders is just a constant value (AP). Arithmetic Sequence is another name for it.
We'd come across the few key phrases in AP that were denoted as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)As shown below, the AP can also be described in terms of common differences.
The following is the formula for determining an AP's n-th term: an = a + (n − 1) × dThe arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' of an AP: d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, according the given condition in the question.
Let the 5th term is defined by 'a₅'.
Let the 6th term is defined by 'a₆'.
Let the 7th term is defined by 'a₇'.
The common difference of the can be calculated as;
d = a₆ - a₅
Now, for the second case, it could be written as;
d = a₇ - a₆
So,
a₇ = d + a₆.
Therefor, the 7th term of an AP can be computed by adding the common difference to the 6th term of an AP.

State the property that justifies the following statement.
If 7(x-3)=35, then 35=7(x-3).
The property that justifies the following statement, if 7(x-3)=35 then 35=7(x-3) is the symmetric property.
Symmetric property is one of the properties of equality which states that if there is an equality sign (=) between two values or numbers, then the two values will always remain equal even if you change the sides of the values. Therefore if ab = cd, then cd = ab
Hence, according to this property, the left side of the equation can be transferred to the right side and the right side of the equation can be transferred to the left side as the order of the equation can be ignored.
The symmetric property also justifies that if the values on the two sides are not equal, then they will remain unequal even if the sides are changed. That is if ab ≠ cd, then cd ≠ ab.
So, according to the symmetric property, the statement, if 7(x-3)=35 then 35=7(x-3) is valid.

Triangle Law of Vector Addition
Triangle law of vector addition states that when two vectors are represented as two sides of the triangle with the order of magnitude and direction, then the third side of the triangle represents the magnitude and direction of the resultant vector.
Parallelogram Law of Vector Addition:
The Parallelogram law states that the sum of the squares of the length of the four sides of a parallelogram is equal to the sum of the squares of the length of the two diagonals.
Given,
Here we need to compare and contrast the law of parallelogram and triangle methods of adding vectors.
While we looking at the definition of the both law,
We have identified that both are performing the sum operation, but Triangle law is for two vectors when the second vector deviates from the direction of the first vector. Note here that second vector starts after the first vector.
Where as in parallelogram law, the two vectors start from the same initial point in two different directions.
