The length of a rectangle is five times the width.

The area of the rectangle is 1620cm squared.

Work out the width of the rectangle

Answers

Answer 1
Hi there!

Let's use x for the width because we know the width is only 1. Next, we'll use 5x for the length because the length is 5 times the width. Now, we can set up an equation to solve for x.

WORK:
x * 5x = 1620
5x^2 = 1620
x^2 = 324
x = 18

ANSWER:
The width of the rectangle is 18 centimeters

Hope this helps!! :)

2. The prices of five different brands of tennis shoes at an athletic store.

3. The shape of the distribution of a team's football scores for one season.

Answers

For #1, the best graph would be a line graph because this data is being described over a period of time.  Line graphs best represent change over time.

For #2, the best graph would be a bar graph because you will easily be able to see the comparison between the prices in the bars.  You will be able to easily see approximate differences and how many times greater or smaller.

For #3, a histogram will best display this data because there will be many scores from a football season to represent, and a histogram organizes a lot of data into intervals while still allowing us to see tendencies in the bars.

what does it mean for an equation to be radical equation

Answers

A radical equation just means that there is a square root symbol over the equation or part of the equation.

A radical equation is just like any other equation, but having some algebraic expression of x's given inside a square-root symbol. It could be as simple as y = [tex]\sqrt{x}[/tex] or it could be any complex algebraic expression inside the radical sign.  

The main condition for existence of any radical equation is that we can not have negative values inside square-root i.e. the algebraic expression given inside radical sign must have non-negative values (zero or positive real values).

A multivitamin tablet contains 16.5mg of calcium. How much calcium does a bottle of 20 tablets contain

Answers

Final answer:

To find the total calcium in a bottle of 20 tablets, multiply the calcium content of one tablet (16.5 mg) by the number of tablets (20), resulting in 330 mg of calcium in the entire bottle.

Explanation:

To calculate the total amount of calcium in a bottle of 20 multivitamin tablets, you simply multiply the amount of calcium in one tablet by the number of tablets. If one tablet contains 16.5mg of calcium, the total amount of calcium in a bottle can be found with the following calculation:

Total amount of calcium = Amount of calcium per tablet × Number of tablets

Total amount of calcium = 16.5 mg/tablet × 20 tablets = 330 mg

So, a bottle of 20 tablets contains 330 mg of calcium.

Make a change of coordinates:

[tex]v(x,y)=\dfrac xy[/tex]

The Jacobian for this transformation is

[tex]\mathbf J=\begin{bmatrix}\dfrac{\partial u}{\partial x}&\dfrac{\partial v}{\partial x}\\\\\dfrac{\partial u}{\partial y}&\dfrac{\partial v}{\partial y}\end{bmatrix}=\begin{bmatrix}y&x\\\\\dfrac1y&-\dfrac x{y^2}\end{bmatrix}[/tex]

and has a determinant of

[tex]\det\mathbf J=-\dfrac{2x}y[/tex]

Note that we need to use the Jacobian in the other direction; that is, we've computed

[tex]\mathbf J=\dfrac{\partial(u,v)}{\partial(x,y)}[/tex]

but we need the Jacobian determinant for the reverse transformation (from [tex](x,y)[/tex] to [tex](u,v)[/tex]. To do this, notice that

[tex]\dfrac{\partial(x,y)}{\partial(u,v)}=\dfrac1{\dfrac{\partial(u,v)}{\partial(x,y)}}=\dfrac1{\mathbf J}[/tex]

we need to take the reciprocal of the Jacobian above.

The integral then changes to

Express the polynomial −4p + 3p + 2p2 in standard form and then classify it.

Answers

Final answer:

The simplified form of the polynomial −4p + 3p + 2p^2 is 2p^2 - p. It is a quadratic polynomial, given that its highest degree of p is 2.

Explanation:

The polynomial −4p + 3p + 2p2 can first be simplified by combining like terms. This results in −p + 2p2. In standard form, always organize the terms in a polynomial so that the powers of x decrease from left to right. Therefore, the standard form of the polynomial is 2p2 - p.

This polynomial can be classified as a quadratic polynomial because the highest power of the variable (p) is 2. A quadratic polynomial is represented by the general form ax2 + bx + c, with 'a' being a non-zero number.

twenty milligrams of the drug lincomycin is to be given for each kilogram of a person's weight. The drug is to be mixed with 250 cc of a normal saline solution, and the mixture is to be administered intravenously over a 1 hour period. Clyde Dexter, who weighs 196 lb, is to be given the drug. Determine the dosage of the drug he will be given?

Answers

Final answer:

To determine the dosage of lincomycin for Clyde Dexter, his weight is first converted to kilograms (88.9 kg), then the prescribed dosage of 20 mg/kg is applied, resulting in a required dosage of 1778 mg.

Explanation:

To calculate the dosage of lincomycin for Clyde Dexter, we first need to convert his weight from pounds to kilograms. Knowing that there are approximately 2.20462 pounds in a kilogram, we can calculate his weight in kilograms. Following this, we will calculate the dosage of lincomycin required based on the prescribed 20 milligrams per kilogram of body weight.



Step 1: Convert Weight to Kilograms

Clyde’s weight in pounds: 196 lb

Conversion factor: 1 kg = 2.20462 lb

Clyde’s weight in kilograms: 196 lb / 2.20462 = 88.9 kg (approximately)



Step 2: Calculate Dosage

Prescribed dosage: 20 mg/kg

Clyde's weight: 88.9 kg

Required dosage of lincomycin: 88.9 kg * 20 mg/kg = 1778 mg



The calculated dosage of lincomycin for Clyde Dexter, based on his body weight, is therefore 1778 mg. This dose is to be mixed with 250 cc of normal saline solution and administered intravenously over a 1 hour period.

A farmer wishes to build a rectangular plot with 800 meters of wire fencing. use calculus to find the maximum area that can be enclosed by the fence

Answers

He has to build a square, so 800÷4=200
200²=40 000 m²

Answer:

40,000 meters squared

Step-by-step explanation:

Find the optimum and constraint equations. (They are just fancy terms for the two equations you need).

The Constraint is 2x + 2y= 800 (As the plot is a normal rectangle and there is 800 m to make a fence, you would use the perimeter formula for a rectangle)

The optimum is xy= A. The area equals length times width (or in this case) xy.

You will need to plug in the simplified constraint into the optimum.

2y= -2x + 800 (divide by two next)

y= -x + 400

Plug in this to the Optimum

x(-x + 400)

this equals -xsquared + 400x

Find the derivative of it

-2x plus 400

Set it equal to )

x=200, this is only one of the lengths of the side.

In order to find the other, plug in x=200 to the constraint

-x + 400

-200 + 400

y = 200 also

So, going back to the Optimum 200 times 200 equals 40,000.

This means that the maximum area is in fact 40,000 meters squared.

Answers

The area of a full circle is given by
  A = π*r^2
so the area of a 1/4 circle will be 1/4 of that:
  A = (π/4)*r^2

The area of a parallelogram is the product of base length and height:
  A = bh

Your composite figure will have an area that is the sum of the areas of the parts.
  A = (quarter circle area) + (parallelogram area)
  A ≈ (3.14/4)*(14 in)^2 +(14 in)*(5 in)
  A ≈ 223.86 in^2 ≈ 224 in^2

The most appropriate selection is the last one,
  224 in^2

The area of composite figure of both Quarter circle and Parallelogram is 224inches.

What is Quarter circle?

"When a Circle is divided into four equal parts, then each parts of a circle is called Quarter of a Circle".

What is Parallelogram?

A parallelogram is "two dimensional geometrical shape, whose sides are parallel to each other".

According to the question,

Area of circle =πr²

Formula for Area of quarter Circle = (π/4)r²

Formula for Area of parallelogram = base × height = (b×h)

In order to find the area of composite figure

Formula for Area of composite figure =  Area of quarter Circle + Area of parallelogram

=  (π/4)r² + (b×h)  

= (3.14/4)(14)² + (14×5)

= 223.86inches ≈ 224inches

Hence, the area of composite figure of both Quarter circle and Parallelogram is 224 inches.

A square on the coordinate plane has vertices at (−2, 2), (2, 2), (2, −2), and (−2, −2). A dilation of the square has vertices at (−4, 4), (4, 4), (4, −4), and (−4, −4). Find the scale factor and the perimeter of each square.

Answers

The smaller square has length of 4. So its perimeter is 4*4 = 16
The larger square has length of 8 and its perimeter is 8*4 = 32

The scale factor is 2.  Since the larger square is twice the size of the smaller square (Or you can say that the scale factor is 1/2 if you are looking at the perspective of the larger square to the smaller square).
Final answer:

The scale factor between the original and dilated square is 2. The perimeter of the original square is 16 units, and the perimeter of the dilated square is 32 units.

Explanation:

The student asked for the scale factor and the perimeter of each square after a dilation on the coordinate plane. The original square has vertices at (-2, 2), (2, 2), (2, -2), and (-2, -2), and the dilated square has vertices at (-4, 4), (4, 4), (4, -4), and (-4, -4).

To find the scale factor, we can compare the coordinates of the original and dilated squares. The x-coordinates (and y-coordinates) of the dilated square are twice those of the original square, indicating that the scale factor is 2. The side length of the original square is 2 - (-2) = 4 units. Given the scale factor of 2, the side length of the dilated square is 4 units × 2 = 8 units.

To calculate the perimeter of each square, we multiply the side length by 4 (since a square has 4 equal sides). The perimeter of the original square is 4 units × 4 = 16 units, and the perimeter of the dilated square is 8 units × 4 = 32 units.

The population standard deviation of the numbers 3, 8, 12, 17, and 25 is 7.563 correct to 3 decimal places. what happens if each of the five numbers is multiplied by 3

Answers

Let's figure this out as though we have no idea what the answer would be.

Step One
Find the new five numbers.
3*3, 8*3, 12*3, 17*3, 25*3
9 , 24 , 36, 51, 75

Step 2
Find the average
(9 + 24 + 36 + 51 + 75)/5 = 195/5 = 39

Step 3
Subtract the individual numbers from the average
(39 - 9) = 30
(39 -24) = 15
(39 - 36) = 3
(39 - 51) = - 12
(39 - 75) = -36

Step 4 
Square the results from Step 3
30^2 = 900
15^2 = 225
3^2 = 9
(-12)^2 = 144
(-36)^2 = 1296

Step 5
Take the average of the results from step 4
(900 + 225 + 9 + 144 + 1296)/5
2574 / 5 = 514.8

Step 6
Take the square root of the result from step 5
deviation = sqrt(514.8)
deviation = 22.689

Step seven 
Compare the two standard deviations.
s2/s1 = 22.689 / 7.563 = 3

Conclusion
If you are given 1 set of numbers to find a population standard deviation and you multiply each member by a, then the result will be a * the standard population deviation of the first set of numbers.

Note
Your calculator will do this as well, but you have to know how to enter the data into your calculator. That requires that you follow the directions carefully. 

This diagram shows a scale drawing for small amphitheater if the scale factor is 1 cm= 10m, what is the area of the actual amphitheater.

A. =40m2
B.=80m2
C.=4,000m2
D.=8,000m2

Please help I will put who right

Answers

A =(b1+b2)h/2
actual b1 =10cm*10m/1cm =100m
actual b2 = 6cm*10m/1 cm = 60m
height = 5 cm*10m/1cm = 50m

A=(100+60)*50/2 = 160*50/2 =80*50= 4,000 m²

Answer : C.=4,000 m²

Answer:

4,000cm^2

Step-by-step explanation:

Q # 2 please find the area

Answers

its answer # 1, 15 squared, this is because the width of the triangle (10) multiplied by the length of the triangle (3) is 30. 30 divided by 2 is 15. You have to dived it by 2, because if you left it as 30, that would be the area if a square made of two of those triangles.

Hope this makes sense :)
Answer:
area = 15 yd²

Explanation:
The area of the triangle can be calculated as follows:
area of triangle = 0.5 * base * height

In the given, we have:
base = 10 yd
height = 3 yd

What is the volume of the composite space figure to the nearest whole number?

Answers

check the picture below.

the volume of a rectangular prism is just the product of its 3 dimensions, so the volume of those two there is 4*9*6  and 3*6*5.

so the volume for the composite figure is just the sum of those two products.

Answer:

A u just have to multiply

Before one month, you will know that Carlos has a minimum of $150, because he deposited $100 to his already $50 account. The following equation is true: [FILL]  $500 = 25m + $150

Have a wonderful day, and may God bless you! :D

Answer:

[tex]150+25m = 500[/tex]    

Step-by-step explanation:

Given : Carlos has $50 in his savings account. He deposits $100 on his birthday, and then another $25 every month.

To Find: Which equation can be used to find the number of months it would take him to reach a balance of $500?

Solution:

Carlos has $50 in his savings account.

He deposits $100 on his birthday.

Let m be the number of months

He save $25 every month

So, he saves in x months = 25 m

Now wants to reach a balance of $500.

So, equation becomes:[tex]50+100+25m = 500[/tex]

                                    :[tex]150+25m = 500[/tex]    

Hence Equation can be used to find the number of months it would take him to reach a balance of $500 is [tex]150+25m = 500[/tex]

The relation passes the vertical line test, so it will be a function. So the statement is true

Which polynomial represents the difference below?

Answers

5x² +9x+3 - (6x² - 3x) = 5x² +9x+3 - 6x² + 3x = -x²+12x +3

Correct answer is B.

The difference between given two polynomials is [tex](- x^{2} + 12x + 3)[/tex].

What is a polynomial?

"A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables."

Given two polynomials are [tex](5x^{2} + 9x + 3)[/tex] and [tex](6x^{2} - 3x)[/tex].

Therefore, the difference between these two polynomials

[tex]= (5x^{2} + 9x + 3) - (6x^{2} - 3x)\\= (5x^{2} - 6x^{2}) + (9x + 3x) + 3\\= - x^{2} + 12x + 3[/tex]

Two cars leave at the same time from points A and B, the distance between them is 280 km. If the cars meet each other, they’ll meet in 2 hours. But if they go in the same direction, then the car going from point A will catch up with the car going from point B in 14 hours. What is the speed of both of the cars?

Answers

Set up the following equations:

[tex]2x + 2y = 280[/tex]

[tex]14x - 14y = 280[/tex]

x represents car A's speed, and y represents car B's speed.

We'll use elimination to solve this system of equations. Multiply the first equation by 7:

[tex](2x + 2y = 280) * 7 = 14x + 14y = 1960[/tex]

[tex]14x - 14y = 280[/tex]

Combine both equations:

[tex]28x = 2240[/tex]

Divide both sides by 28 to get x by itself:

[tex]x = 80[/tex]

The speed of car A is 80 mph.

Since we now know the value of one of the variables, we can plug it into the first equation:

[tex]2(80) + 2y = 280[/tex]

[tex]160 + 2y = 280[/tex]

Subtract 160 from both sides.

[tex]2y = 120[/tex]

Divide both sides by 2 to get y by itself:

[tex]y = 60[/tex]

The speed of car B is 60 mph.

A system with 6 independent components is such that the system will fail if at least one of the individual components fail. the probability that a component fails is 0.02. let a be the event that the system fails. what is the probability of a ?

Answers

The components operate independently, so the probability of "total" system failure is the same as the product of each probability of component failure. That is, if [tex]A_i[/tex] denotes the event that component [tex]i[/tex] fails, then

[tex]\mathbb P(A)=\mathbb P(A_1\cup\cdots\cup A_6)=\mathbb P(A_1)\times\cdots\times\mathbb P(A_6)[/tex]

The [tex]A_i[/tex] are independent and identically distributed, so [tex]\mathbb P(A_i)=\mathbb P(A_j)[/tex] for all [tex]i,j[/tex]. So

[tex]\mathbb P(A)=\mathbb P(A_1)^6=0.02^6=6.4\times10^{-11}=0.000000000064[/tex]
