Question 1: What do you notice about the picture?

Question 2: What do you wonder about the image?

Question 3: What is the information in the picture trying to tell you?

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.

The area of a regular 8 sides polygon with radius 4 units long is 309 unit²

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

The space enclosed by the boundary of a plane figure is called its area.

The area of a figure is the number of unit squares that cover the surface of a closed figure.

Given is a regular 8 sides polygon with radius 4 units long, we need to find its area,

We know that the regular 8-sided polygon is called an Octagon.

Area of an octagon =

A = 2(1+√2)a²

a = side

A = 2(1+√2)8²

A = 2(2.41)64

A = 309

Hence, the area of a regular 8 sides polygon with radius 4 units long is 309 unit²

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

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.

The number of different types of movies that Lavar can buy according to the inequality m > 15 is action and comedy.

What is meant by inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. However several inequalities are utilised to compare the numbers, whether it is less than or higher than. An inequality symbol has non-equal expressions on both sides. It indicates that the expression on the left should be bigger or smaller than the expression on the right, or vice versa. Literal inequalities are relationships between two algebraic expressions that are expressed using inequality symbols.

The complete question is given below.

The inequality to be used is m > 15.

Now we will look into each genre to select which movies he could buy.

There are 18 action movies.

m = 18 > 15.

There are 18 comedy movies as well.

m = 18 > 15

There are 12 drama movies.

but m = 12< 15

There are 15 thriller movies.

But the given inequality allows only categories with a number of movies greater than 15 and not equal to 15.

Therefore the number of different types of movies that Lavar can buy according to the inequality m > 15 is action and comedy.

Therefore, using the rule of 72, it would take approximately 9 years for Sofia's $18,000 investment to double at a rate of 8% in interest.

Percent is a term used to describe a value that is a fraction of 100. It is often represented by the symbol "%".  Percentages are commonly used to express rates, ratios, and proportions in many fields, including finance, science, and everyday life. They are often used to describe changes in value, such as increases or decreases in prices, population, or other quantities over time.

Here,

The rule of 72 is a simple formula used to estimate the time it takes for an investment to double in value based on its rate of return. To use this rule, divide 72 by the annual percentage yield (APY) to get an estimate of the number of years it would take for the investment to double.

In this case, the APY is 8%, so we can apply the rule of 72 as follows:

Number of years to double = 72 / APY

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.

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.

Answer:

it will cost $520.00 to install the gravel path.

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of the diagonal of the rectangular garden. The Pythagorean theorem states that the square of the length of the hypotenuse (in this case, the diagonal) of a right triangle is equal to the sum of the squares of the lengths of the other two sides. Therefore, we have:

diagonal^2 = 24^2 + 32^2

diagonal^2 = 576 + 1024

diagonal^2 = 1600

Taking the square root of both sides, we get:

diagonal = sqrt(1600)

diagonal = 40 feet

Now, we need to calculate the area of the path that Jorge will install. Since the path is 2 feet wide, the width of the garden is reduced by 4 feet (2 feet on each side). Therefore, the length and width of the garden after the path is installed will be:

length = 24 - 4 = 20 feet

width = 32 - 4 = 28 feet

The area of the path is the difference between the area of the garden before and after the path is installed:

area of path = (24 * 32) - (20 * 28)

area of path = 768 - 560

area of path = 208 square feet

Finally, we can calculate the cost of the gravel path by multiplying the area of the path by the cost per square foot:

cost of path = 208 * 2.50

cost of path = $520.00

Therefore, it will cost $520.00 to install the gravel path.

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.

Therefore, the length of AC is √(145) inches.

A triangle is a three-sided polygon, which means it is a flat shape with straight sides. It is the simplest polygon, consisting of three line segments connected end-to-end. The corners where the sides meet are called vertices, and the line segments themselves are called edges or sides. The interior angles of a triangle always add up to 180 degrees. Triangles can be classified according to the lengths of their sides and the sizes of their angles. Common types of triangles include equilateral triangles, isosceles triangles, scalene triangles, acute triangles, right triangles, and obtuse triangles.

Here,

        A

       / \

      /   \

     /     \

    / B    C

   /_|\___/ \

  D       E   \

Since triangle ABC is right-angled at B, we know that angle BAC is a right angle. We can use this fact to find the length of AC by applying the Pythagorean theorem. Let x be the length of AC:

AC² = AB² + BC² (by the Pythagorean theorem)

AC² = AD² + BD² + BC² (by the definition of right triangles)

AC² = AD² + CD² + BC² (since BCD = DCA)

AC² = AE² + EC² + CD² (since BAE = EAC)

AC² = 9² + EC² + 8² (since AE = 9 inches and CD = 8 inches)

Now we need to find EC. We can use the fact that BAE = EAC to find the relationship between AE and EC. Let y be the length of BE:

AE/BE = AC/BC (by the angle bisector theorem)

9/y = x/(BC-y) (substituting the given values)

9(BC-y) = xy

BCy - y² = (9/ x) y²

Next, we can use the fact that BCD = DCA to find the relationship between BD and DC. Let z be the length of AD:

BD/DC = BA/AC

(BD/DC) = (AB/AC) (since B is the right angle)

BD/8 = (x²)/(x² + 8²)

Now we have two equations with two variables (y and z). We can use substitution to solve for one variable in terms of the other. Let's solve for y in terms of z from the first equation:

BCy - y² = (9/x) y²

BCy = y² (9/x + 1)

y(BC - y) = y² (9/x + 1)

y² (BC - y - (9/x + 1)) = 0

Since y cannot be zero, we must have:

BC - y - (9/x + 1) = 0

BC - y = 9/x + 1

Now let's substitute this expression for y into the second equation:

BD/8 = (x²)/(x² + 8²)

BD = (8x²)/(x² + 64)

Since BCD = DCA, we have:

BD/CD = BC/AC

(8x²)/(x² + 64) / 8 = BC/x

BC = x² / (x² + 64)

Now we can substitute this expression for BC into the equation we derived earlier:

BC - y = 9/x + 1

x²/(x² + 64) - y = 9/x + 1

Substituting the value we derived for BD into the equation, we get:

x²/(x² + 64) - 8x²/(x² + 64) = 9/x + 1

Simplifying, we get:

x² = 145

x = √(145)
