Describe bar graph

The pictorial representation of data which is generally grouped, in the form of vertical or horizontal rectangle-shaped bars is called a bar graph. In this type of graph, the length of bars is a representation of the measure of data. They are also called bar charts. In statistics, bar graphs are one of the ways of data handling.

Statistics is the collection, presentation, analysis, organization, and interpretation of data observations. There are various methods for the representation of this statistical data. These can be tables, bar graphs, pie charts, histograms, frequency polygons, etc.

A theatre contains 457 seats and the ticket prices for a recent play were ​$54 for adults and ​$17 for children. If the total proceeds were ​$14,984 for a​ sold-out matinee, how many of each type of ticket were​ sold?

Answers

Answer: 195 adult tickets and 262 children tickets

Step-by-step explanation:

     Let a be adult tickets and c be children tickets.

We know there are 457 seats.

     a + c = 457

We also know the cost of the tickets and how much money was made.

     $54a + $17c = $14,984

Now, we have a system of equations we can use to solve.

     a + c = 457

     $54a + $17c = $14,984

Lastly, we will graph this system, see attached. The point of intersection, or where the lines intersect, is our answer.

     195 adult tickets and 262 children tickets.

Answer:

Chidden tickets were 262 and adult tickets were 195 tickets

Step-by-step explanation:

Let x = the number of children tickets

Let y = the number of adult tickets.

x + y = 457

17x + 54y = 14984

Use substitution

x + y = 457 Solve for y

y = 457 -x  Substitute 457 -x for y in the equation 17x + 54y = 14984

17x + 54y = 14984

17x + 54(457 -x) = 14984  Solve for x  Distributer the 54

17x + 24678 - 54x = 14984  Combine like terms

-37x = -9694   Divide both sides by -37

x = 262

The number of children tickets.

x + y = 457  Substitute 262 for x and solve for y

262 + y = 457  Subtract 262 from both sides

y = 195

The number of adult tickets.

what is the cosine of angle b

Answers

For the given right angled triangle cosine of angle B is 5√89/89.(option A).

What is right angled triangle?

It is a particular type of triangle having one angle is 90° or right angle. The adjacent sides of the right angle are called base and the perpendicular and the opposite side of 90° is called hypotenuse.

The given triangle is the right angled triangle. The three sides of a right angled triangle are called base, perpendicular and hypotenuse.

In the given figure base=  5 inches and perpendicular = 8 inches

By Pythagoras theorem at first we will find out the hypotenuse. Let the hypotenuse= c inches

For any right angled triangle,

(perpendicular)² +(base)²= (hypotenuse)²

⇒ (8)² + (5)² = (c)²

⇒ 64+ 25 = c²

⇒ c² =89

⇒ c= ±√89

As hypotenuse cannot be negative

So hypotenuse = √89 inches.

Now to find cosine of angle B that is cos B we will use the trigonometric function.

cos B= Adjacent side/ hypotenuse

         = 5/√89

        = 5√89/89 [ Multiplying the numerator and the denominator by √89 ]

Hence, cosine of angle B is 5√89/89.

according to the question the balance in the account earning compound interest after 6 years is $4,156.22.

what is interest ?

Multiply the principal with the rate of interest, the time period, and various other factors to determine simple interest. Simple returns = money + interests + hours is the marketing formula. This approach makes calculating interest the simplest. The approach to calculating interest that is most usually employed is as a percentage over the principal sum. For instance, he will just pay his share of the interest at 100% when he borrows $100 with a friend and agrees to shell out it back with 5% interest. $100 has been reduced to $5 (0.05). Every time you borrow money, you must pay interest, which is applied to whatever loans you make. On the loan balance, interest is typically calculated using an annual percentage.

given,

To calculate the balance in the account earning compound interest after 6 years, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the sum of money at the end of the period of time

P stands for the principle (beginning sum).

the decimal representation of the annual interest rate (r).

n represents how many times the interest rate is compounded annually.

t is the duration (in years).

In this case, we have:

P = $3500 (the principal)

r = 2.16% = 0.0216 (the annual interest rate)

Since interest is compounded four times a year (quarterly), n is equal to four.

t = 6 (the time period is 6 years)

With these values entered into the equation, we obtain:

A = 3500(1 + 0.0216/4)^(4*6)

A = $4,156.22

A rectangle has a length of x + 4 cm and a width of 2x − 7 cm.
(a) If the perimeter is 36cm, what is the value of x?
(b) What is the area of this rectangle

Answers

Answer:

See below!

Step-by-step explanation:

Given data:

Length = x + 4 cm

Width = 2x - 7 cm

Part a)

Perimeter:

Sum of all sides of a shape is called perimeter.Perimeter of rectangle = 2(length) + 2(width)

Put the given data.

36 = 2(x + 4) + 2(2x - 7)

Distribute

36 = 2x + 8 + 4x - 14

Combine like terms

36 = 2x + 4x + 8 - 14

36 = 6x - 6

Add 6 to both sides

36 + 6 = 6x

42 = 6x

Divide both sides by 6

42/6 = x

7 = x

OR

x = 7Part b)Area of rectangle = length × width

Area = (x + 4)(2x - 7)

Put x = 7

Area = (7 + 4)(2(7) - 7)

Area = 11(14 - 7)

Area = 11(7)

Area = 77 cm²

[tex]\rule[225]{225}{2}[/tex]

Answer: (a) x=7

(b) area of this rectangle = 77[tex]cm^{2}[/tex]

Step-by-step explanation:

(a) the perimeter of a rectangle = 2 * [  l + b ]

36 = 2 * [ (x + 4) + (2x - 7) ]

36 / 2 = x + 4 + 2x - 7

what is trigonometry identity ?

A trigonometric identity is an equation that is true for all values of the variables in the equation, where the variables are trigonometric functions such as sine, cosine, tangent, cotangent, secant, or cosecant.

The Pythagorean identity is a fundamental trigonometric identity that relates the three basic trigonometric functions: sine, cosine, and tangent, in terms of the unit circle or right triangle.

Proof of cot²(x) - tan²(x) = csc²(x) - sec²(x)

The identity you provided, cot²(x) - tan²(x) = csc²(x) - sec²(x), is a trigonometric identity that can be derived from the Pythagorean identity and the reciprocal identities. Here's one way to prove it:

Start with the Pythagorean identity:

sin²(x) + cos²(x) = 1

Divide both sides by sin²(x):

1 + cos²(x)/sin²(x) = 1/sin²(x)

Recall that cot(x) = cos(x)/sin(x) and tan(x) = sin(x)/cos(x):

1 + cot²(x) = csc²(x)

Subtracting sec²(x) from both sides:

cot²(x) - tan²(x) = csc²(x) - sec²(x)

Therefore, cot²(x) - tan²(x) = csc²(x) - sec²(x) is a valid trigonometric identity.

What is a domain?

In Mathematics and Geometry, a domain can be defined as the set of all real numbers for which a particular function is completely defined.

How to determine the true statement?

Since the domain of this function is given by -20 ≤ x ≤ 5, it simply means that the value of x must between -20 and 5. Also, with a range of -5 ≤ g(x) ≤ 45, the value of x must between -5 and 45.

By extrapolating the function, we can deduce that:

g(0) = -2

g(-9) = 6

g(-13) = 20

In this context, we can reasonably infer and logically deduce that based on the answer options provided, g(-13) = 20 is the only statement that could be true for the function g.

The amount of chalk that is greater is yellow.

Michelle is correct because more than 1/2 the chalk in the bucket is blue.

How to determine which amount of chalk is greater?

In order to determine the amount of chalk that is greater between the amount of yellow chalk and amount of green chalk, we would have to find the difference between them as follows;

Difference = 2/6 - 3/12

Difference = (4 - 3)/12

Difference = 1/12 (positive value)

Similarly, we can determine the greater amount of chalk as follows;

2/6 × 2/2 = 4/12

4/12 > 3/12

Total number of chalks = 2/6 + 5/12 + 3/12

Total number of chalks = (4 + 5 + 3)/12

Total number of chalks = 12/12

Total number of yellow and green chalks = 2/6 + 3/12

Total number of yellow and green chalks = (4 + 3)/12

Total number of yellow and green chalks = 7/12 chalks.

1 - 7/12 = 5/12

7/12 - 1/2 = 6/12 (Michelle is correct).

Explain complex numbers

Complex numbers are numbers that consist of a real part and an imaginary part, expressed as a+bi, where a and b are real numbers and i is the imaginary unit. They are used in mathematics to represent solutions to equations that cannot be solved using only real numbers.

According to the given information

To add complex numbers (4+√(-20i)) and (5+√(-30i)), we add their real parts separately and their imaginary parts separately:

Real parts: 4 + 5 = 9

Imaginary parts: √(-20i) + √(-30i)

We can simplify each of the square roots using the fact that:

√(-1) = i

Therefore:

√(-20i) = √(20) * √(i) = 2√(5) * i

√(-30i) = √(30) * √(i) = √30) * i * √(-1) = √(30) * i^2 = -√(30)

So the imaginary parts simplify to:

2√(5)i - √(30)

Putting it all together, we get:

(4+√(-20i)) + (5+√(-30i)) = 9 + (2√(5)i - √(30)) = 9 - √(30) + 2√(5)i

For an investment of 26,245, a quarterly statement reports that the account is 26,292. The statement reports that for the same quarter, the rate of return of the investment was - 0.02%. Given the information regarding the investment quarterly activity, does the reported rate of return seem reasonable?

Answers

No. The reported return rate appears lower than expected.

Rate of returns

To determine whether the reported rate of return is reasonable or not, we can calculate the expected rate of return based on the investment amount and the ending value of the account.

First, we need to calculate the total number of quarters that have elapsed between the initial investment and the current quarter. Let's assume that the investment has been held for n quarters.

Then, we can use the following formula to calculate the expected rate of return:

Expected rate of return = (Ending value / Initial investment) ^ (1/n) - 1

Plugging in the given values, we get:

n = 1 (since we are only given information for a single quarter)

Initial investment = 26,245

Ending value = 26,292

Expected rate of return = (26,292 / 26,245) ^ (1/1) - 1 = 0.18%

Comparing the expected rate of return of 0.18% with the reported rate of return of -0.02%, we can see that they are quite different. However, it's important to note that a single quarter's rate of return may not be indicative of the overall performance of the investment.

Therefore, while the reported rate of return seems lower than expected, we would need to consider the performance over a longer period of time to make a more informed assessment of the investment's performance.

Find the minimum or maximum of the function y=x^2-9

Answers

I will be finding the minimum of this parabolic function.

The function y = x^2 - 9 is a parabola that opens upwards, since the coefficient of the x^2 term is positive. Therefore, the minimum value of the function occurs at the vertex of the parabola.

To find the x-coordinate of the vertex, we can use the formula -b/2a, where the quadratic function is in the form y = ax^2 + bx + c. In this case, a = 1 and b = 0, so the x-coordinate of the vertex is -b/2a = -0/(2*1) = 0.

To find the corresponding y-coordinate of the vertex, we can substitute x = 0 into the function, which gives y = 0^2 - 9 = -9.

Therefore, the minimum value of the function y = x^2 - 9 is -9, which occurs at x = 0.

~~~Harsha~~~

Answer:

The minimum point of this function is located at (0, -9).

Step-by-step explanation:

1. Determine whether it's a minimum or maximum.

So from plain sight we can tell we're looking for a maximum point, because the coefficient of x² is positive, it's 1. If the function was y=-x²-9, we would be looking at a minimum point.

2. About the minimum...

The vertex if the exact point where a quadratic or any pair exponent function will start to either decay or increase, therefore, it will be the minimum or maximum point.

Formula for "x" value of vertex: [tex]\sf x_{Vertex} =\dfrac{-b}{2a}[/tex].

In this equation, a and b are coefficients extracted when the formula is expressed on its standard form.

Standard form of a quadratic equation: ax² + bx + c = 0

➔ You need to substitute the "y" by a "0", and the formula should look like this:

[tex]\sf 0=x^2-9[/tex]

➔ Reorganizing...

[tex]\sf x^2-9=0[/tex]

3. Extracting the coefficients.

Let's expand the previous expression:

[tex]\sf x^2+0x_{} -9=0[/tex]

The coefficients are:

a= 1, beacuse "x²" is being multiplied by 1, which is implicit.

b= 0, because "x" doesn't really exist on the simplified equation.

c= -9.

4. Calculate the "x" and "y" locations of the vertex.

Now let's calculate the "x" position of the vertex using the formula from step 2:

[tex]\sf x_{Vertex} =\dfrac{-b}{2a}=\dfrac{-(0)}{2(1)}=0[/tex]

Now, the "y" value can be obtained just by substituting "x" by 0 on the argument of the function:

[tex]\sf y=(0)^2-9\\ \\y=-9[/tex]

Therefore, the vertex, or minimum point of this function is located at (0, -9).

Company A charges a $125 annual fee plus $7 per hour car share fee.
Company B charges $110 plus $10 per hour. What is the minimum number of
hours that a car share needs to be used per year to make company A a better
deal?
OA. 9
B. 6
O C. 5
D. 11

Answers

Let x be the number of hours of car sharing per year. Then the cost of using Company A is given by:

Cost of Company A = $125 + $7x

The cost of using Company B is given by:

Cost of Company B = $110 + $10x

We want to find the minimum number of hours of car sharing per year such that Company A is a better deal than Company B. In other words, we want to find the value of x such that:

Cost of Company A < Cost of Company B

125 + 7x < 110 + 10x

15 < 3x

5 < x

So the minimum number of hours of car sharing per year to make Company A a better deal is 6 hours. Therefore, the answer is B!!

A rectangular room is 2 feet
longer than it is wide. Its area is 168 square feet. Set this up as a quadratic equation

Answers

Answer:

x = -14 and x = 12

Step-by-step explanation:

Let x be the width of the rectangular room in feet. Then, according to the problem, the length of the room is 2 feet longer than the width, or x + 2 feet.

The area of a rectangle is given by the formula A = length × width, so we have:

A = (x + 2) × x = x^2 + 2x

We are also given that the area of the room is 168 square feet, so we set A = 168 and get:

x^2 + 2x = 168

This is a quadratic equation in standard form, where 1x^2 + 2x - 168 = 0. We can solve this equation by factoring or using the quadratic formula. This will give us the value(s) of x, which represents the width of the room. Once we have the width, we can find the length by adding 2 feet to it.

And x is :  -14 and 12
