Answer: 146.12 m/s (to the right)

Step-by-step explanation:

The Conservation of Linear Momentum principle states that the initial momentum [tex]p_{i}[/tex] (before the elastic collision) must be equal to the final momentum [tex]p_{f}[/tex] (after the elastic collision):

[tex]p_{i}=p_{f}[/tex] (1)

Being:

[tex]p_{i}=m_{r}V_{r} + m_{b}V_{b}[/tex]

[tex]p_{f}=m_{r}U_{r} + m_{b}U_{b}[/tex]

Where:

[tex]m_{r}=0.311 kg[/tex] is the mass of the racket

[tex]V_{r}=30.3 m/s[/tex] is the velocity of the racket before the collision

[tex]m_{b}=0.057 kg[/tex] is the mass of the ball

[tex]V_{b}=-19.2 m/s[/tex] is the velocity of the ball before the collision

[tex]U_{r}=0 m/s[/tex] is the velocity of the racket after the collision  (assuming it is at rest after hitting the ball)

[tex]U_{b}[/tex] is the velocity of the ball the collision

So, we have the following:

[tex]m_{r}V_{r} + m_{b}V_{b}=m_{r}U_{r} + m_{b}U_{b}[/tex]  (2)

Finding [tex]U_{b}[/tex]:

[tex]U_{b}=\frac{m_{r}V_{r} + m_{b}V_{b}}{m_{b}}[/tex] (3)

[tex]U_{b}=\frac{(0.311 kg)(30.3 m/s) + (0.057 kg)(-19.2 m/s)}{0.057 kg}[/tex] (4)

Finally:

[tex]U_{b}=146.12 m/s[/tex] This is the velocity of the ball after the collision

The Area of the Ferris wheel is 31400 Square feet

Step-by-step explanation:

The AREA formula for a circle:

The Area formula for the circle is [tex]\pi r^2[/tex]

where

r is the radius of the circle

The area of the Ferris Wheel:

The Height of the Ferris wheel =  200 foot

Here height of the Ferris wheel is the diameter

So the Diameter = 200

Then Radius =[tex]\frac{200}{2}[/tex] = 100 foot

Now the area of the Ferris wheel is

=> [tex]\pi (100)^2[/tex]

=> [tex]\pi \times 10000[/tex]

=> 31400 square feet

Answer:

8 3/5

Step-by-step explanation:

subtract the whole numbers first and then the fractions. you have 10 4/5-2 1/5. subtract the whole numbers and you have 8(put that off to the side). then do 4/5-1/5. 4-1=3 and the denominators stay the same so you have 3/5. you don’t need to simplify so your final answer is 8 3/5.

Answer:

43 / 5 or 8 3/5

Hope this helps!

The problem is a mathematical exercise in determining the total number of movies rented from the provided percentage of those returned. By setting up an equation and solving it, we find that the total number of movies rented was 700.

The student's question is on a mathematical concept related to percentages and determining the whole from a percentage portion. From the information provided, 434 movies, which represent 62% of the total number of movies rented last week, were returned. To calculate the total number of movies rented, we can let the total be x. With this, the equation representing the scenario is 0.62x = 434.

By solving for x, we get x = 434 / 0.62. After the calculation, we find that the total number of movies rented last week was 700. Therefore, the store originally rented out 700 movies.

Remember that when dealing with percentages, the percentage value (in this case, 62%) must be converted into decimal form before performing any calculation. This is done by dividing the percentage by 100, thus 62% becomes 0.62. For clarity, here's the step-by-step procedure:

The tending of rabbits, known as rabbit farming or rabbit husbandry, involves providing adequate resources for the rabbits to mature and reproduce. This could be for the purposes of obtaining meat, fur, or wool from the rabbits. It's also important to monitor for signs of infection to prevent communicable diseases.

The tending or caring of rabbits is commonly referred to as rabbit husbandry or rabbit farming. This involves the raising and breeding of rabbits, often for their meat, fur, or sometimes, for their wool in the case of certain breeds like the Angora Rabbit.

Aspects of rabbit husbandry can include providing an adequate food source, healthcare, and a suitable living environment. It is imperative to watch out for any signs of infection, as some diseases can be transmitted from the rabbits to humans through eating or handling infected rabbits. Some such infections could be vector-borne, passing through ticks or flies, or potentially through aerosols in a laboratory setting.

These caretaking measures help ensure that a young rabbit can develop into a healthy adult rabbit, capable of reproducing or providing the intended resource, whether it be meat, fur, or wool.

Answer:

Step-by-step explanation:

Letters are variables and those variable can store a number

Ex: x=5  y=2

evaluate : 3x+2y

we know that x is 5, so we know that 3x would be 15

we know that y is 2, so we know that 2x would be 4

then it says to add 3x and 2y, we would add 15 and 4 to get 19

(This is a very simple example, when you get older, the expression would be much more confusing.

Answer:

Step-by-step explanation:

1) pentagon; n= 5

Sum of interior angles = 180*(n -2) = 180* (5-2) = 180 * 3 = 540

2) Sum of interior angles of a polygon = 1080

180*(n-2) = 1080

n - 2 = 1080/180

n -2 = 6

n = 6+2

n = 8

Polygon has 8 sides

3) Sum of interior angles of a polygon = 6840

180*(n-2) = 6840

n - 2 =6840/180

n -2 = 38

n = 38 + 2

n = 40

Polygon has 40sides

4)Sum of interior angles of an octagon = 180*(n-2) = 180* (8-2) = 180 - 6 = 1080

The sum of the interior angles of the 10-sided polygon on the left is 1440 °.

The answer is : 1440

Answer:

45°

Step-by-step explanation:

We know ∠ Y +∠ S = 90

and ∠ S= 5 ( ∠ Y)-180  so

leave S alone for both

90- ∠Y = 5 ( ∠Y) -180

270 = 6( ∠Y )

45= ∠ Y

∠S = 5( 45) -180

     =225-180

     =45

Final answer:

The measure of angle Y (m∠Y) is 45°, following the equation derived from the facts that angles S and Y are complementary and m∠S equals 5 times m∠Y minus 180°.

Explanation:

If ∠S and ∠Y are complementary angles, then the sum of their measures is 90°. According to the given information, m∠S = 5(m∠Y) − 180°. Since m∠S + m∠Y = 90°, we can set up the equation:

5(m∠Y) − 180° + m∠Y = 90°

Combining like terms to solve for m∠Y:

6(m∠Y) = 90° + 180°

6(m∠Y) = 270°

m∠Y = 270° / 6

m∠Y = 45°

The measure of angle Y, m∠Y, is 45°.

You can park in the garage for 5 hours 30 minutes

Solution:

Given that, shopping mall parking garage charges $2 for the first half hour and $1.20 for each additional half hour (even if it is under 30 minutes)

Therefore,

Cost for first half an hour = $ 2

Cost for each additional half an hour = $ 1.20

Let "x" be the number of each additional half hour

Therefore, total cost to pay is given as:

Total cost = Cost for first half an hour + (Cost for each additional half an hour)(number of each additional half hour)

Total cost = 2 + 1.20x

Given you have $ 8 in cash

[tex]8 = 2 + 1.20x\\\\1.20x = 8 - 2\\\\1.20x = 6\\\\x = \frac{6}{1.20}\\\\x = 5[/tex]

Total hours parked = first half an hour + 5

Thus you can park in the garage for 5 hours 30 minutes

Option A

[tex]\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}[/tex]

Solution:

Given expression is:

[tex]\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}[/tex]

Product of powers property:

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

[tex]a^m.a^n = a^{m+n}[/tex]

Therefore, the given expression becomes,

[tex]\left(y^{\frac{4}{3}+\frac{2}{3}}\right)^{\frac{-1}{2}}[/tex]

Now add the exponents, we get

[tex]\left(y^{\frac{4+2}{3}}\right)^{\frac{-1}{2}}[/tex]

Simplify the above expression

[tex]\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}[/tex]

Simplify the exponent of y, we get

[tex]\left(y^{2}\right)^{\frac{-1}{2}}[/tex]

Find the equation of the line with negative slope

we know that

The line with negative slope has a y-intercept at (0,-5)  and passes through the point (2,-6)

Find the slope

[tex]m=(-6+5)/(2-0)=-\frac{1}{2}[/tex]

The equation in slope intercept form is

[tex]y=-\frac{1}{2}x-5[/tex]

Convert to standard form

Multiply by 2 both sides

[tex]2y=-x-10\\x+2y=-10[/tex]

step 2

Find the equation of the line with positive slope

The line with positive slope has a x-intercept at (4,0)  and passes through the point (2,-6)

Find the slope

[tex]m=(-6-0)/(2-4)=3[/tex]

The equation of the line in point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=3\\point\ (4,0)[/tex]

substitute

[tex]y-0=3(x-4)[/tex]

Convert to standard form

[tex]y=3x-12\\3x-y=12[/tex]

therefore

The system of equations is

- x + 2y = −10

3x − y = 12
