Answer:
E
Step-by-step explanation:
For Company A, the monthly cost y in dollars can be represented by:
y = 0.12x + 20
where x is the number of minutes used.
For Company B, the monthly cost y in dollars can be represented by:
y = 0.06x + 50
where x is the number of minutes used.
To find the number of minutes of calls where the monthly bills will be the same, we need to set the two equations equal to each other and solve for x:
0.12x + 20 = 0.06x + 50
0.06x = 30
x = 500
Therefore, the monthly bills will be the same for both companies when the number of minutes used is 500.
Answer: (E) 500 minutes

XY ?
From the given scenario, AB = [17 + 28, 47 + 58] = [23, 64]
How to calculate the product of matrices XY,To calculate the product of matrices XY, the number of columns in X must match the number of rows in Y. In this case, X has 1 column and Y has 2 rows, so the product XY is undefined.
A general example of this with matrices is:
Let A be a 2x3 matrix:
A = [1 2 3; 4 5 6]
Let B be a 1x2 matrix:
B = [7 8]
To calculate the product AB, we need the number of columns in A to match the number of rows in B.
In this case, A has 3 columns and B has 1 row, so the product AB is:
AB = [17 + 28, 47 + 58] = [23, 64]

What is the period of the graph of y= 1/2 sin(pi x) + 3?
A. Pi
B. 2
C. 3
D. 1/2
Answer:
B. 2
Step-by-step explanation:
The standard form of a sine function is given by:
y = A sin(Bx - C) + D
where A is the amplitude, B is the frequency, C is the phase shift, and D is the vertical shift.
In the given function y = 1/2 sin(pi x) + 3, we can see that the amplitude is 1/2, the frequency is pi, the phase shift is 0, and the vertical shift is 3.
The period of a sine function is given by:
Period = 2π/B
In this case, B = pi, so the period is:
Period = 2π/pi = 2
Therefore, the period of the graph of y = 1/2 sin(pi x) + 3 is 2, which is option B.
Answer:
Step-by-step explanation:
The period is 2.
Normally the period of sin(x) is 2pi, but the pi inside the sin(pix) is a horizontal compression by a factor of 1/pi. So 2pi·1/pi = 2
The "1/2" and "+3" do not impact the period. Those just impact the amplitude (vertical aspect) of the graph.

Which statement is sometimes true?
Question 2 options:
A square is a rhombus.
A trapezoid is a parallelogram.
A rectangle is a parallelogram.
A rectangle is a square.
Answer:
A square is a rhombus.
Step-by-step explanation:
When rotated 45 degrees, a square can sometimes be a rhombus (aka a diamond). A rhombus can have four equal sides with four right angles, just like a square.
A trapezoid cannot be a parallelogram. A parallelogram has two sides that are parallel with each other going horizontally and two that are also parallel but going diagonally.
A parallelogram opposite sides are equal while rectangles have opposite sides that are equal as well as all of its adjacent sides being perpendicular to form right angles. A parallelogram has no right angles. The diagonals of a rectangle are equal whereas the diagonals of a parallelogram are not.
A rectangle is a closed 2D shape with four straight edges and four right angles, also the diagonals are equal. A square on the other hand is a closed 2D shape with four straight edges, four right angles, and four equal sides. Squares can be rectangles but not all rectangles can be squares.

Answer: Para resolver el ejercicio se plantea un diagrama de conjuntos, en el
cual se representan un conjunto A y B ( Ver dibujo adjunto ) .
b +x = 46% a + x = 60% a + b = 58%
Al sumar las dos ecuaciones :
b + x = 46%
a + x= 60%
--------------------------
a + b +2x = 106%
58% + 2x = 106%
2x = 106% - 58%
2x = 48%
x = 48%/2
x = 24% no leen ninguna de las dos revistas
c = 63000 personas que leen A y B
se llama al total de personas y :
y * 18% = 63000 personas
y = 63000 / 18%
y = 63000/0.18 = 350000 son las personas hay en Trujillo

Para un cóctel se compraron 500 panes y sólo se utilizó el 75% cuántos panes se consumieron
Se compraron 500 panes, pero solo se utilizó el 75%, lo que significa que se consumió el 100% - 75% = 25% de los panes. Para calcular la cantidad de panes que se consumió, podemos multiplicar la fracción de panes consumidos (25% o 0.25) por el número total de panes:
0.25 x 500 = 125
Por lo tanto, se consumieron 125 panes en el cóctel.

What is 8 and 5/8 minus 4 and 1/4
Answer:
2 3/8
Step-by-step explanation:
8 [tex]\frac{5}{8}[/tex]
- 4 [tex]\frac{1}{4}[/tex]
First you got to get the fractions to have the same denominator (or bottom number)
In this case it would be 8. You would multiply the 4 in 1/4 to get 8, and what you do to the bottom you have to do to the top, so the 1 would multiply by 2 as well to get to.
So the new equation would be,
8 [tex]\frac{5}{8}[/tex]
- 4 [tex]\frac{2}{8}[/tex]
5-2= 3
And the denominator stays the same so the fraction would be 3/8.
8-4=4 so the whole number would be 4
Making the full answer 4 3/8

Show your work.
A sequence of transformations to rectangle JKLM that will result in rectangle J'K'L'M' is a translation by 3 units and -4 units, a reflection about the y-axis, and a rotation of 90 degrees counterclockwise about the origin.
What is a rectangle?A rectangle is a quadrilateral with four right angles and four sides of equal length. It is one of the most common shapes in nature and is found in everything from architecture to floor patterns. A rectangle is a two-dimensional shape that has four sides and four angles, all of which are right angles, and two pairs of opposite sides which are parallel.
In order to transform rectangle JKLM into J'K'L'M', a series of transformations must be applied. The first transformation is a translation of the rectangle along the x-axis by 3 units and along the y-axis by -4 units. This will move the original rectangle from its original position, JKLM, to the new position, J'K'L'M'. Next, a reflection about the y-axis needs to be applied, which will flip the rectangle around the y-axis. This will result in the length of side K'L' being 6 units. Finally, a rotation about the origin needs to be applied. The rotation should be 90 degrees counterclockwise in order for the coordinates of vertex K' to be (-3,2) and the coordinates of vertex M' to be (3,-2). Therefore, a sequence of transformations to rectangle JKLM that will result in rectangle J'K'L'M' is a translation by 3 units and -4 units, a reflection about the y-axis, and a rotation of 90 degrees counterclockwise about the origin.

Which equation would calculate the amount of wrapping paper, in square centimeters, needed to completely cover the cylinder shown?
a cylinder with the diameter labeled 2.6 centimeters and the height labeled 3.8 centimeters
SA = 2π(1.3)2 + 1.3π(3.8)
SA = 2π(2.6)2 + 2.6π(3.8)
SA = 2π(2.6)2 + 1.3π(3.8)
SA = 2π(1.3)2 + 2.6π(3.8)
SA = 2π(1.3)² + 1.3π(3.8) is the equation that calculate the amount of wrapping paper, in square centimeters, needed to completely cover the cylinder shown.
How to find the correct formula?The correct equation to calculate the amount of wrapping paper, in square centimeters, needed to completely cover the cylinder is:
SA = 2πr(h + r)
where r is the radius of the cylinder (which is half of the diameter), and h is the height of the cylinder.
In this case, the radius is 1.3 centimeters (half of the diameter of 2.6 centimeters), and the height is 3.8 centimeters. Therefore, the correct equation to calculate the surface area (amount of wrapping paper needed) is:
SA = 2π(1.3)(3.8 + 1.3)
SA = 2π(1.3)(5.1)
SA ≈ 41.82 square centimeters
So, the amount of wrapping paper needed to completely cover the cylinder is approximately 41.82 square centimeters.
Identify the relevant measurements of the cylinder: In this case, the problem states that the cylinder has a diameter of 2.6 centimeters and a height of 3.8 centimeters.
Calculate the radius of the cylinder: The radius of the cylinder is half of its diameter. So, divide the diameter by 2: 2.6/2 = 1.3 centimeters. Therefore, the radius of the cylinder is 1.3 centimeters.
Use the formula for the surface area of a cylinder: The formula for the surface area of a cylinder is SA = 2πr(h + r), where r is the radius of the cylinder and h is its height. Plug in the values for r and h: SA = 2π(1.3)² + 1.3π(3.8).
Thus, SA = 2π(1.3)² + 1.3π(3.8) is the equation that alculate the amount of wrapping paper, in square centimeters, needed to completely cover the cylinder shown.
