Answer:

5/12

Step-by-step explanation:

4/12+3/12=7/12

12/12-7/12=5/12

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

Answer:

pie is equal to the square root of A divided by r

Step-by-step explanation:

Set the equation first...a=pie times r squared. Then u need to get rid of everything to make pie by itself. U square both sides or all the equation. the square cancels out and on the other side, it will be the square root of a. Next, divide by r on each sides. The r cancels out. Then it's gonna be pie =the square root of a all over r. It can't be a/r square because in the original...pie is being multiplied by r which is squared so that means both variables are squared. U cant find pie if the square is stopping it so u square for the very first step

The complete question is:

A geometric sequence is defined recursively by

    [tex]a_{(1)}=40\text{ and }a_n=(-1/2)a_{(n-1)}[/tex]

(a) Write out the first four terms of this sequence.

(b) Is the 9th term of this sequence larger or smaller than 1/10? Show the calculation that you use to determine your answer.

Answer:

Explanation:

You are given the first term,    [tex]a_(1)=40[/tex] , and the recursive formula

   [tex]a_{(n)}=(-1/2)a_{(n-1}[/tex]

Thus, you can find the sequence of terms by multiplying each term by the constant ratio, (-1/2).

(a) First four terms of the sequence

[tex]a_{(1)}=40\\ \\ a_{(2)}=40\times (-1/2)=-20\\ \\ a_{(3)}=-20\times (-1/2)=10\\\\ a_{(4)}=10\times (-1/2)=-5[/tex]

Those are the first four terms.

(b) 9th term

You can write the explicit formula of the sequence as:

[tex]a_{(n)}=a_{(1)}\times r^{(n-1)}\\ \\ a_{(n)}=40(-1/2)^{(n-1)}[/tex]

Thus, for the 9th term, n = 9, and the term is:

[tex]a_{(9)}=40\times (-1/2)^{(9-1)}\\ \\ a_{(9)}=40\times(-1/2)^8\\ \\ a_{(9)}=40\times(1/256)=0.1526[/tex]

Since 1/10 = 0.1, and 0.1 < 0.1526, the 9th term is larger than 1/10.

The answer to that problem is:

[tex]36 {a}^{8} {b}^{8} [/tex]

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10

If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

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:

53/50

Step-by-step explanation:

The ratio of males to females is 53:50.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Number of baby boys = 106

Number of baby girls = 100

So, the ratio of males to females

= 106/100

= 53/50

Hence, the ratio of males to females is 53:50.

The calculated coordinates of the point F is (-1, 5)

How to determine the coordinates of F

From the question, we have the following parameters that can be used in our computation:

D(2,3),E(-5,2),G(6,6)

We have that

The quadrilateral DEFG is a parallelogram

This means that the opposite sides have equal slopes

i.e.

Slope of DE = Slope of FG

Using slope formula, we have

(3 - 2)/(2 + 5) = (y - 6)/(x - 6)

This gives

1/7 = (y - 6)/(x - 6)

Cross multiply

x - 6 = 7y - 42

x = 7y - 36

Set y = 5

So, we have

x = 7 * 5 - 36

x = -1

So, we have

(x, y) = (-1, 5)

Hence, the coordinates of the point F is (-1, 5)

Question

Consider the parallogram DEFG with three vertices D(2,3),E(-5,2),G(6,6). Find the coordinates of F.

Final answer:

To find the coordinates of vertex F in the parallelogram DEFG with given vertices D(2,3), E(-5,2), and G(6,6), we can use vector subtraction to deduce that the coordinates of F are (-1, 5).

Explanation:

The question requires us to find the coordinates of vertex F of the quadrilateral DEFG given that we have the coordinates of vertices D(2,3), E(-5,2), and G(6,6). Assuming that DEFG is a parallelogram (as the question implies a symmetry-based approach though it doesn't specify), we can find F using the properties of parallelograms, which dictate that opposite sides are equal and parallel. The vector from D to E is ∂D = (-5 - 2, 2 - 3) = (-7, -1), and the vector from G to F (let's call it F's coordinates (x, y)) would be equivalent, as they are opposite sides. So, G + ∂D = F. Substituting G's values, we get (6 - 7, 6 -1), which simplifies to (-1, 5). Thus, the coordinates of F are (-1, 5).

Solution:

Given that we have to factor the given polynomial by grouping

Given polynomial is:

[tex]xy+2y^2+3x+6y[/tex]

Factoring by grouping means that you will group terms with common factors before factoring.

This is done by grouping a pair of terms. Then factor each pair of two terms

In the given polynomial, group the terms that has "x" as common and group the terms that has "y" as common

[tex](xy+3x)+(2y^2+6y)[/tex]

Factor out "x" from first group and factor out "2y" from second group

[tex]x(3+y)+2y(y+3)[/tex]

Factor out y + 3

[tex]x(3+y)+2y(y+3) = (x+2y)(y+3)[/tex]

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:

A = 3/4B

A = 72.75

3/4B = 72.75

B = 72.75 * 4/3

B = 291/3 = 97

you would save (97 - 72.75) = $ 24.25 when buying them at store A

By calculating the original price of the headphones at Store B and subtracting the price at Store A, we find that you would save $24.25 by purchasing the headphones at Store A.

To find out how much you save by buying the headphones at Store A, we need to determine the original price of the headphones at Store B.

Let's denote the price at Store B as P. According to the information given, the price at Store A is 3/4 of the price at Store B. We can write the following equation:

P × (3/4) = $72.75

Solving for P, we get:

P = $72.75 ÷ (3/4)
  P = $72.75 ÷ 0.75
  P = $97.00

Therefore, the price of the headphones at Store B is $97.00. To find the savings, subtract the price at Store A from the price at Store B:

Savings = Price at Store B - Price at Store A
  Savings = $97.00 - $72.75
  Savings = $24.25

By buying the headphones at Store A, you save $24.25.

It is NOT possible for a solution to be both x<9 and x>9

It IS possible for a solution to be both x≤9 and x≥9

Step-by-step explanation:

Because for x<9 and x>9 the GREATER than symbol means it less than 9 and cannot be 9 or it is greater than 9 but cannot be 9.

With x≤9 and x≥9 the greater than or EQUAL sign makes a big difference. Because x≥9 may be the actual solution but since it is possible to be  equal to 9 so can x≤9.
