A hamster running in a wheel of radius 13 cm spins the wheel at 35 revolutions per minute.
a) What is the angular velocity of the wheel? (in radians/sec)
Select an answer
b) At what linear velocity is the hamster running? (in cm/sec)
Select an answer

Answers

Answer 1

One revolution is completed when a fixed point on the wheel travels a distance equal to the circumference of the wheel, which is 2π (13 cm) = 26π cm.

So we have

1 rev = 26π cm

1 rev = 2π rad

1 min = 60 s

(a) The angular velocity of the wheel is

(35 rev/min) * (2π rad/rev) * (1/60 min/s) = 7π/6 rad/s

or approximately 3.665 rad/s.

(b) The linear velocity is

(35 rev/min) * (26π cm/rev) * (1/60 min/s) = 91π/6 cm/s

or roughly 47.648 cm/s.

Answer 2

The angular velocity of the wheel is 3.665 radians/sec.

The linear velocity is the hamster running is 47.648 cm/sec.

Given

A hamster running in a wheel of radius 13 cm spins the wheel at 35 revolutions per minute.

What is angular velocity?

Angular Velocity It is defined as the rate of change in angular displacement of a particle in a circular motion.

The angular velocity of the wheel is given by;

[tex]\rm 1 \revolution = 2\pi \ radians\\\\Angular \ velocity = 35 \times 2\pi \ radians \ per \ minute\\\\Angular\ velocity = 70\pi \ radians \ per\ minute\\\\1 \ min = 60\ second\\\\Angular \ velocity = 70\pi \times \dfrac{1}{60} \\\rm \\Angular \ velocity = \dfrac{7}{6} \times 3.14 \ radians \ per \ second\\\\Angular \ velocity = 3.65\ radians \ per \ second\\\\[/tex]

The angular velocity of the wheel is 3.665 radians/sec.

What is linear velocity?

Linear velocity definition deals with the measurement of an object’s velocity when it moves along a specific direction.

The linear velocity is the hamster running is given by;

[tex]\rm Linear \ velocity = 35 \times 26\pi \times \dfrac{1}{60}\\\\Linear \ velocity = 35 \times 26 \times 3.14 \times \dfrac{1}{60}\\\\ Linear \ velocity =47.648 \ cm \ per \ second[/tex]

The linear velocity is the hamster running is 47.648 cm/sec.

Answers

there are different negatives and positives

Answer:

Sample response:

Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

7/9 greater or less than 0.7777

Answers

We can conclude that 7/9 is equal to 0.777.

What mathematical operations are exactly?Calculating a value while utilizing operands and a math operator is known as a mathematical "operation."The supplied operands or numbers must follow specific guidelines that are associated with the symbol for the math operator.Addition, subtraction, multiplication, division, exponentiation, and modulus are all operations carried out by arithmetic operators.

So, we need to solve 7/9 to know if it is greater, less, or equal to 0.777.

7/9 = 0.7777So, 7/9 is equal to 0.777

(Refer to the image attached below for calculation)

Therefore, we can conclude that 7/9 is equal to 0.777.

what's the square root of 1/36?

Answers

0.27... repeating :)

The square root of the number is A = 1/6 = 0.16667

Given data ,

Let the first number be represented as p

where the value of p = 1/36

Now , the square root of the number is expressed as

A = √p

The radical form of a number refers to expressing a number using a radical symbol (√) to represent a root.

It is used to express the roots present in the number.

So , A = √( 1/36 )

On simplifying , we get

A = 1/6

On further simplification , we get

A = 0.166667

Hence , the square root is A = 1/6 = 0.16667

because of how its written you would be multiplying 4x by 1/6 if they asked you to solve it. but since they asked you to write the equation all you have to do is put 4x on one side of the equal sign and 1/6 on the other so if they ask you to solve it all you have to do is multiply both sides by 1/6

Solve for w: -4u-w = u+6w

Answers

Answer:

A

Step-by-step explanation:

-4u - w = u + 6w

-4u = u + 7w  (Add w to both sides)

-5u = 7w (Subtract u from both sides)

w = [tex]-\frac{5u}{7}[/tex] (Divide both sides by 7)

Answer:

w=(-5u)/7

Step-by-step explanation:

-4u-w=u+6w

Combine like terms

-4u-u=6w+w

-5u=7w

Divide both sides by 7 to cancel it out on the right side and isolate w

(-5u)/7=(7w)/7

(-5u)/7=w

w=(-5u)/7

Solve the quadratic equation by completing the square.
x2 + 8x + 19 = 0
What’s the answer ? Math algebra 2

Answers

Answer: x= 4 ± [tex]\sqrt{-3}[/tex]

Step-by-step explanation:

[tex]x^{2}[/tex] + 8x + 19 = 0     First subtract 19 from both sides

             -19    -19

[tex]x^{2}[/tex] + 8x           =  -19    Now to complete the square on the left side you will divide 8 by 2 and square the number that you will get and add it to both sides. If you divide 8 by 2 you get 4 and  4 squared is 16 .So add 16 to both sides.

x^2 + 8x + 16 = -19 + 16  Now factor the left side

(x+4)^2 = -3    Take the square root of both sides

(x+4) = ±[tex]\sqrt{-3}[/tex]        

Subtract 4 from both sides

x = ±[tex]\sqrt{-3} - 4[/tex]

While sitting in class you overheard one of your classmates say, "This equation has infinite solutions, because when I put it in Desmos it gave me parallel lines so I know it makes a conditional equation." Realizing that the student is incorrect, what would you say to help your classmate get their facts straight?

Answers

Answer:

See below

Step-by-step explanation:

The systems of linear equations represent two lines.

There are 3 possible outcomes with two lines on the plane.

1. Lines intersect

In this case there is one solution, which is the point of intersection.

2. Lines are parallel

In this case the lines never intersect, so there is no solution

2. Lines are same

In this case the lines overlap, so there are infinitely many solutions.
