Complete the given diagram by dragging expressions to each leg of the triangle. Then, correctly complete the equation Not all expressions will be used. Then correctly complete the equation to derive the distance, d.
What we have here in the picture is a graph of a segment. The goal is to find the segment's length, which we can do by using the distance formula:[tex]d^2=\left(x_2-x_1\right)^2-\left(y_2-y_1\right)^2[/tex].
What is graph?
A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Note that the distance between two points is equal to the length of the line segment that joins them.
So now we already have answers for two of the boxes.
The difference in the x-coordinates gives us the horizontal distance between the two points, while the difference in the y-coordinates gives us the vertical distance between the points.
So, the other two boxes should contain:

Step-by-step explanation:
The integers 6,21 from the set will make the inequality 3(j-5)>3(7-2j) true.
What is inequality?Inequality is the unequal distribution of resources, opportunities, or rewards among individuals or groups in society. It can occur in many forms, such as unequal access to healthcare, education, employment, or other resources, or unequal treatment based on race, gender, ethnicity, and other factors. Inequality can also manifest as unequal income and wealth distribution, as well as unequal access to political power and decision-making. Inequality can be caused by a variety of factors, including structural factors and personal or individual-level factors, such as discrimination. Inequality can have a negative effect on both individuals and societies, leading to social and economic inequities that can be difficult to overcome.
The given inequality is 3(j-5)>3(7-2j). The given set is S:{−4, 4, 6, 21}.
First, we will simplify the given inequality.
3(j-5)>3(7-2j)
⇒j-5>7-2j
⇒3j>12
⇒j>4
It means that numbers greater than 4 will satisfy the given inequality.
Numbers greater than 4 in the given set are 6,21.

Find the value of x and y in the below diagram. TL is the perpendicular bisector of BF. TE = 2x - 10, EL = 8x-17, BE = 3x+6, and BF = 7x-5, m
Hello,
I hope you and your family are doing well!
To find the value of x, we can use the fact that TL is the perpendicular bisector of BE. This means that TL splits BE into two segments of equal length. Therefore, we have:
EL + BF = BE
Substituting the values for EL, BF, and BE gives:
[tex](8x - 17) + (7x - 5) = (3x + 6)[/tex]
Combining like terms gives:
[tex]15x - 22 = 3x + 6[/tex]
Subtracting 3x from both sides gives:
[tex]12x - 22 = 6[/tex]
Adding 22 to both sides gives:
[tex]12x = 28[/tex]
Dividing both sides by 12 gives:
[tex]x = 28/12 = 7[/tex]
Now that we know the value of x, we can use this value to find the value of y. We can use the equation TE = 2x - 10 to find the value of TE:
TE = 2x - 10 = 2 * 7 - 10 = 14 - 10 = 4
Now we can use the equation EL = 8x - 17 to find the value of EL:
EL = 8x - 17 = 8 * 7 - 17 = 56 - 17 = 39
Since TL is the perpendicular bisector of BE, the length of TL is the average of the lengths of EL and TE. The average of EL and TE is:
(EL + TE)/2 = (39 + 4)/2 = 43/2 = 21.5
So the length of TL is 21.5, and the value of y is 21.5 and x is 7

Given that, 1) a circle with circumferences = 2πr and radius = r, 2) a circle having circumferences = 76 cm and 3) Jada is painting a table having diameter 37 in.
1) Assume the figure as a rectangle, (refer to attached figure)
We get, the length of it is πr and width is r.
And the area of a rectangle is = the Product of length and width.
So, we can conclude that the area of this rectangle is = πr×r = πr²
Therefore, by assuming the figure as a rectangle, we can explain why the area of a circle is πr²
2) circumferences = 2πr
2πr = 76
πr = 38
r = 38/3.14 (π ≈ 3.14)
r = 12.01 cm
Diameter = 2r
D = 2x12.01 = 24.20 cm
Area = πr²
= 3.14x12.01²
= 452.91 cm²
3) Diameter = 37 in
r = 37/2 = 18.5 in
Area = πr²
= 3.14x18.5²
= 1074.66 in²
Therefore, the area of the table is 1074.66 in²
Hence, the answers are 1) We can explain why the area is πr² by assuming the figure as a rectangle, 2) Diameter = 24.20 cm, Area = 452.91 cm² and 3) the area of the table is 1074.66 in²

Michelle invests in a savings account that pays 5% interest compounded monthly. What is the APY for this account ?? (Round to the nearest 0.00%)
Only answer if you know!!
The account's APY is 5.12%.
Waht is APY.Annual Percentage Yield, or APY, is the rate that may be earned on an account over the course of a year and includes compound interest.
The annual percent yield, or APY, accounts for interest compounding. Because it takes into account the interest you earn on your money, it accurately reflects the interest rate you really receive on an investment.
Consider the previous illustration, where a $100 investment generates a 5% quarterly compounded return. On the $100, you receive interest throughout the first quarter. However, in the second quarter, you also receive interest on the $100 in addition to the first quarter's interest.
The APY (Annualized Percentage Yield) formula is:
APY = [tex](1+i/N)^{N} -1[/tex]
where, i = Nominal rate = 5%, N = Number of compounding periods = 12
putting the values in the above formula, we get,
APY = (1 + 5% / 12)^12 - 1
APY = (1 + 0.4167%)^12 - 1
APY = (1 + 0.0041667)^12 - 1
APY = (1.0041667)^12 - 1
APY = 1.051161897 - 1
APY = 0.051161 or 5.12%

11) The second pair of coordinate on the line perpendicular to q and passes through the point (3, 5) is (2, 0).
What is a slope?When the ratio is expressed as a quotient ("rise over run"), the same number is provided for every two distinct locations on the same line. There is a negative "rise" on a descending line.
Given,
Line q passes through (3, 5), (-2, 4)
(y-y₁)=m(x-x₁)
(y-5)=((4-5)/(-2-3))(x-3)
(y-5)=(-1/-5)(x-3)
-5y+25=-x+3
x-5y+22=0
10) Given point is (0,1)
Slopes are equal for parallel lines.
So, (y-1)/(x-0)=(-1/-5)
-5y+5= -x
x-5y+5=0Let y=0 then,
x= -5
Therefore, the second pair of coordinate on the line parallel to q and passes through the point (1, 0) is (-5, 0).
11) The equation of a line perpendicular to q is,
(y-y₁)=(-1/m)(x-x₁)

Step-by-step explanation:
Given equation:
[tex]t^2-10t+6=7[/tex]
When completing the square for a quadratic equation, the first step is to move the constant to the right side of the equation:
[tex]\implies t^2-10t+6-6=7-6[/tex]
[tex]\implies t^2-10t=1[/tex]
Add the square of half the coefficient of the term in x to both sides to form a perfect square trinomial on the left side:
[tex]\implies t^2-10t+\left(\dfrac{-10}{2}\right)^2=1+\left(\dfrac{-10}{2}\right)^2[/tex]
Simplify:
[tex]\implies t^2-10t+\left(-5\right)^2=1+\left(-5\right)^2[/tex]
[tex]\implies t^2-10t+25=1+25[/tex]
[tex]\implies t^2-10t+25=26[/tex]
Factor the perfect square trinomial on the left side:
[tex]\implies (t-5)^2=26[/tex]
Square root both sides:
[tex]\implies \sqrt{(t-5)^2}=\sqrt{26}[/tex]
[tex]\implies t-5=\pm \sqrt{26}[/tex]

The second-period interest and amount after two months, if The principal amount is $400, The rate of interest is 6% per annum, are $4.02 and $406.02 respectively.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
The principal amount, P = 400,
The rate of interest, r = 6% per annum,
The time period, t = monthly = 1 / 12 year,
Calculate the simple interest for the first month as shown below,
Simple interest = [tex]p\times r\times t/100[/tex]
Simple interest = 400 × 6 × 1 / (12 × 100)
Simple interest = 2
Thus, the amount of the first month is the principle for the second month,
Amount of the first month = Principal of the second month = 400 + 2 = 402,
Calculate the simple interest for the second month as shown below,
Simple interest = [tex]p\times r\times t/100[/tex]
Simple interest = 402 × 6 × 2 / (12 × 100)
Simple interest = 4.02
Amount after two months = 402 + 4.02 = 406.02.
