The missing segment lengths are CD = 10√2, AC = 10√2, BC = 10 and AB = 10.
Drag each length to the correct location accordingly
How to find the missing segment lengths?Trigonometry is a branch of mathematics dealing with the relationship between the ratios of the sides of a right-angled triangle with its angles.
In ΔACD,
sin 45° = CD/20 (sin = opp/hyp)
(√2)/2 = CD/20
CD = (√2)/2 × 20
CD = 10√2
cos 45° = AC/20 (cos = adj/hyp)
(√2)/2 = AC/20
AC = (√2)/2 × 20
AC = 10√2
In ΔABC,
sin 45° = BC/10√2 (sin = opp/hyp)
(√2)/2 = BC/10√2
BC = (√2)/2 × 10√2
BC = (10 × 2)/2
BC = 10
cos 45° = AB/10√2 (cos = adj/hyp)
(√2)/2 = AB/10√2
AB = (√2)/2 × 10√2
AB = 10
Drag each length of the missing segment to the correct location

4. BK has endpoints B(1, 4) and K(4, -3). Rotate BK clockwise 270 degrees about the
origin.
Part AWrite an algebraic description of the transformation of BK.
Part B: What are the endpoints of the new line segment?
The algebraic description of the transformation of B(x, y) = B'(y + 0, 0 - x)
The algebraic description of the transformation of K(x, y) = K'(y + 0, 0 - x)
The endpoints of the new line segment are B'(4, -1) and K'(-3, -4).
As per the given data BK has endpoints B(1, 4) and K(4, -3).
Rotate BK clockwise 270 degrees about the origin.
Every point of a source image is transformed in a plane via a rotation that rotates it around a fixed point at a specific angle and direction. The fixed point is referred to as the rotational center.
The term "angle of rotation" refers to the rotation's amount and is expressed in degrees.
Rotating a figure 270 degrees clockwise is the same as rotating a figure 90 degrees anticlockwise.
Now, it would be (x, y) = (-y, x)
We have;
R (x, y) to R' (y, -x)
The algebraic description is simply written as;
R (x, y) = R'(y + 0, 0 - x)
B (x, y) = B'(y + 0, 0 - x)
K (x, y) = K'(y + 0, 0 - x)
To get the new endpoints, we simply write the transformation as shown;
B(1, 4) becomes B'(4, -1)
K(4, -3) becomes K'(-3, -4)

In the arrangement below, each number is the non-negative difference of the two numbers above it. What is the sum of the four greatest distinct possible values for $z$
The numbers in the arrangement can be represented by x, y, z, a, b, c and d, where x is at the top and d is at the bottom. The relationship between the numbers is as follows:
x = y - z
y = a - b
z = c - d
We can use this information to find the values of z, c, and d in terms of x, y, and a:
z = y - x
c = z + d
d = z - c
Since we are looking for the four greatest distinct possible values for z, we can assume that x, y, and a are as small as possible (i.e. 0) and c and d are as large as possible.
Thus, the four greatest distinct possible values for z are:
z = y - x = 0 - 0 = 0
z = a - y = 0 - 0 = 0
z = c - d = c
z = c - d = d
The sum of these four values is 0 + 0 + c + d = c+d.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. The following table shows the number of sales each salesman had during the first three weeks of this month.
Week 1 Week 2 Week 3
Salesman A 11 14 16
Salesman B 14 15 13
Salesman C 16 12 11

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of sales be represented as x
Let the maximum weekly salary of Salesman C be = $ 900
Now , the weekly salary of Salesman A = $ 65x
where x is the number of sales
And , the weekly salary of Salesman B = $ 300 + $ 40x
Now , on week 1,
Salesman A made 11 sales
Substitute the value of x = 11 in the equation , we get
So , the salary of Salesman A on week 1 = 65 ( 11 )
On simplifying the equation , we get
The salary of Salesman A on week 1 = $ 715
And , Salesman B made 14 sales
Substitute the value of x = 14 in the equation , we get
The salary of Salesman B on week 1 = 300 + 40 ( 14 )
On simplifying the equation , we get
The salary of Salesman B on week 1 = 300 + 560
The salary of Salesman B on week 1 = $ 860
So , Salary of Salesman C on week 1 > salary of Salesman B on week 1 > salary of Salesman A on week 1
And , $ 900 > $ 860 > $ 715
Hence , the solution to the equation is week 1

Tell whether the rate form a proportion. 4. 8 lap every 8 minute; 3. 6 lap every 6 minute
Yes, the rate 4.8 laps every 8 minutes; 3.6 laps every 6-minute form a proportion.
A proportion is an equation that sets two ratios at the same value. For instance, you might express the ratio as follows:
1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)
4.8 lap every 8 minutes will be equal to (4.8/8) = 0.6 lap a minute.
3.6 lap every 6 minutes will be equal to (3.6/6) = 0.6 lap in a minute.

Si se tiene cierta cantidad de alimento para mantener por 14 días a 40 cerdos; la cantidad de días que puedo mantener a los cerdos si se aumentan en un 40% es.
Answer:
La cantidad de días para mantener una población de cerdos mayor en 40 % es de 10 días.
Step-by-step explanation:
Para una misma cantidad de alimentos, el tiempo de duración de los alimentos ([tex]t[/tex]) es inversamente proporcional a la cantidad de cerdos ([tex]c[/tex]), es decir:
[tex]t \propto \frac{1}{c}[/tex]
[tex]t = \frac{k}{c}[/tex] (1)
Donde [tex]k[/tex] es la constante de proporcionalidad, en días.
Podemos eliminar esa constante mediante la siguiente relación:
[tex]\frac{t_{1}}{t_{2}} = \frac{c_{2}}{c_{1}}[/tex] (2)
Si sabemos que [tex]t_{1} = 14\,dias[/tex], [tex]c_{1} = 40[/tex] and [tex]c_{2} = 56[/tex], entonces la cantidad de días asociada una población de cerdos mayor en 40 % es:

What is a proportion?
A proportion is an equation that states that two ratios are equal. It can be written in the form of a/b = c/d. The two ratios, a/b and c/d, are called the terms of the proportion.
The cross-products of a proportion are also equal, so ad = bc.
To solve for d in the equation 5/1.5 = 50/d, you can start by multiplying both sides of the equation by 1.5 to cancel out the denominator on the left side. This gives:
5 = 50/d * 1.5
Next, you can simplify the right side of the equation by multiplying 50 and 1.5, which gives:
5 = 75/d
To solve for d, you can now cross-multiply to get:
75 = 5d
Finally, you can divide both sides of the equation by 5 to get:
d = 75/5
d = 15
the value of d is 15.
Hence, the depth of water from the shore is 15 feet.

ADEF has coordinates D(2, 0), E(3, 3), and F(4, 1). What are the coordinates of AD E F if the original triangle is dilated by a scale factor of 4?
Option C is correct. The coordinates of ADE'F' after dilation by a scale factor of 4 are A'(8,0), D'(8,0), E'(12,12), and F'(16,4).
What are coordinates?Using one or more numbers, or coordinates, a coordinate system in geometry establishes a unique way to locate points or other geometrical objects on a manifold, such Euclidean space. The order of the coordinates is important, and they can sometimes be distinguished by their place in an ordered tuple or by a letter, such as "the x-coordinate." In simple mathematics, the coordinates are assumed to be real numbers, while they could also be complex numbers or components of a more abstract structure, such a commutative ring. Analytic geometry is based on the usage of coordinate systems, which make it possible to convert geometry-related problems into numerical problems and vice versa.
