What is the period of the function graphed below?

300 degrees

Step-by-step explanation:

The area of the composite figure  with 3 semicircles connected to 3 sides of a square is (6π+16)[tex]cm^{2}[/tex].

A semicircle is a plane shape that is a part of a circle divided into two equal parts through its diameter.

Analysis:

Since the semicircles are connected to 3 sides of a square 4cm, the diameter of the semicircle is 4cm.

Radius of semicircle = 4/2 = 2cm

Area of a semicircle = π[tex]r^{2}[/tex]/2 = [tex]\pi[/tex][tex](2)^{2}[/tex]/2 = 2π[tex]cm^{2}[/tex]

For three semicircles = 3 x 2π[tex]cm^{2}[/tex] = 6π[tex]cm^{2}[/tex]

Area of square = [tex]s^{2}[/tex] = [tex](4)^{2}[/tex] = 16[tex]cm^{2}[/tex]

Area of composite figure  = Area of 3 semicircles + area of square

Area of composite figure = (16 + 6π)[tex]cm^{2}[/tex]

In conclusion, the area of the composite figure is  (16 + 6π)[tex]cm^{2}[/tex].

Answer: A binomial has a specified number of trials just before an experiment begins, and X counts the number of achievements acquired within that limited number. While a geometric, on the other hand, has a fixed number of successes and counts the number of attempts necessary to reach the first success. 

Step-by-step explanation:

This is only for the first question i don't know the second one sorry

The required difference between binomial and geometric models is In binomial there is to count of the number of successes, and in the geometric model, only the first success counts.

GIven that,
To determine how do binomial and geometric models differ and situations would a geometric model be better than a binomial model.

In mathematics, it deals with numbers of operations according to the statements.

Binomial distribution describes the number of successes k achieved in n trials and Given a finite number of trials, the geometric distribution is useful for calculating the chance of success.

Before an experiment starts, a binomial has a set number of trials, and X counts the number of successes attained within that fixed number. A geometric, on the contrary, count the number of efforts required to attain the first success and has a set number of successes.

The experiment can have an infinite number of attempts before success, unlike the binomial distribution which has a fixed number of trials, hence the geometric distribution is useful to describe the number of failures before the first success in such a sequence of trials.

Thus, the required difference between binomial and geometric models is In binomial there is to count of the number of successes, and in the geometric model, only the first success counts.

Step-by-step explanation:

Remark

You need to choose between tan(30) and tan(60). Tan(60) = √3 which has a rational denominator (1).

Tan(60) = opposite / adjacent

Tan(60) = √3

Given

opposite = x

adjacent = 4

Theta = 60

Tan(theta) = √3

Solution

Tan(theta) = opposite / adjacent       Substitute values

√3 = x / 4                                            Multiply both sides by 4

4√3 = x

Answer

x = 4√3

Given the values of the circumference and volume, the height  of the tree trump to the nearest tenth is 36.0in.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )

Given the data in the question;

First we determine the radius of the circular base.

Since circumference C = 2πr then r = C / 2π.

Hence, the volume of the cylinderical tree stump will be;

V = π × (C / 2π)² × h

V = π × ( C² / 4π² ) × h

V =  hC² / 4π

4πV = hC²

h = 4πV / C²

We substitute our given values into the expression

h = ( 4 × 3.14 × 20214in³ ) / (84in)²

h = 253887.84in³ / 7056in²

h = 36.0in

Therefore, given the values of the circumference and volume, the height  of the tree trump to the nearest tenth is 36.0in.

The average speed of Keane’s journey is 56.25 miles per hour

The given parameters are:

The average speed is calculated as:

Speed = Distance/Time

This gives

Speed = 180 miles/3.2 hours

Evaluate the quotient

Speed = 56.25 miles per hour

Hence, the average speed of Keane’s journey is 56.25 miles per hour

Part A

Reason:

The range, IQR, and the standard deviation are all measures of spread.

IQR stands for Interquartile Range. Unfortunately your teacher made a typo and wrote IRQ by mistake.

The symbol [tex]\sigma[/tex] is the greek letter sigma used to represent the population standard deviation.

The smaller these measures are, the more less spread out the values will be. This leads to the most consistent data set. Think of it like being on an archery range. The more consistent shots are closely clustered around the same point (not necessarily the center), while the less consistent shots are more randomly scattered about.

School B has the smallest range, IQR, and standard deviation of the three schools. Therefore, this school has the most consistent attendance.

=============================================================

Part B

Reason:

This school has the highest mean, and also the largest median, of all three schools. Both of these are measures of center or average. Compared to school B, this data set is a bit more spread out and not as consistent.

Of two traingles

Of 3 rectangles

TSA

Answer:

96 ft²

Step-by-step explanation:

As the base of the prism (the triangle) is an equilateral triangle (the sides are the same length), the surface area of the prism comprises:

Area of a rectangle = width × length

⇒ area of the rectangle = 3 ft × 10 ft = 30 ft²

Area of a triangle = 1/2 × base × height

⇒ area of the triangle = 1/2 × 3 ft × 2 ft = 3 ft²

Total surface area = 3 × area of the rectangle + 2 × area of the triangle

                              = 3 × 30 ft² + 2 × 3 ft²

                              = 90 ft² + 6 ft²

                              = 96 ft²

Answer:

=29 in³

Step-by-step explanation:

Volume of a cone = 1/3×π×2³×11

= 29 in³ (to the nearest whole number)

This is called system of equations because you are searching a pair of numbers that inserted as x and y verify both equations at the same time.

To solve a system of equation you have to use one equation to express one variable as a function of the other, and substitute the result in the second equation.

In your case you have

y = x - 2

So your y  variable will be always equal to x - 2 , even in the second equation. Then we can write

x - 2 = 4x + 1

Here I replaced the "value" of y in the second equation.

Now you have an equation in one variable that you can solve as usual

x - 2 = 4x + 1

4x - x = - 2 - 1

3x = -3

x = -1

With a value for x you can substitute in one of the two equations and obtain y. Because both equations has to be valid at the same time, both equations must give you the same number for y.  Let's try:

y = x - 2

y = - 1 - 2

y = -3

and, with the second equation

y = 4x + 1

y = 4 ( - 1 ) +  1

y = - 4 + 1

y = -3

It works! Then our solution is given by x = -1 and y = -3.

To graph this, simply plot these coordinates.

Question:

In three days Tina sold 15 boxes. On the second day, she sold 1 more than on the first. On the third day, she sold 5 more than on the first. How many boxes did she sell on the third day?

Answer:

8. Tina sold eight boxes on the third day.

Step-by-step explanation:

Three days, 15 boxes.

On the first day, Tina sold 3 boxes.

On the second, she sold one more than on the first. (4)

On the third day, she sold five more than on the first. (8)

 3 + 4 = 7

7 + 8 = 15

So your answer would be:

Tina sold eight boxes on the third day.

The 104 adults and 105 youth admissions were purchased if the admission fee is $8.00 for an adult and $4.50 for a youth.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

We have:

At the local fair, the admission fee is $8.00 for an adult and $4.50 for a youth.

Let's suppose the number of admission of adults is x and for youth is y, then,

x + y = 209 ...(1)

8x + 4.50y = 1304.5 ...(2)

After solving the above two linear equation, we get:

x = 104

y = 105

Thus, the 104 adults and 105 youth admissions were purchased if the admission fee is $8.00 for an adult and $4.50 for a youth.
