After the collision, cart a moves in the negative x direction with a speed of 4 m/s, and cart b moves in the positive x direction with a speed of 2 m/s.

In a perfectly elastic collision, the total momentum of the system is conserved, as well as the total kinetic energy. This means that the sum of the momenta of the carts before the collision is equal to the sum of the momenta after the collision. In this case, since cart b is initially at rest, its initial momentum is zero.

We can use conservation of momentum to determine the final velocities of the carts. Let the velocity of cart b after the collision be v, then the velocity of cart a after the collision is -4 m/s. The momentum of cart a before the collision is m(4 m/s) = 4m, and the momentum of cart b after the collision is 3mv.

Using conservation of momentum, we have:

m(4 m/s) + 0 = m(-4 m/s) + 3mv

Simplifying this equation, we get:

8m = 3mv + 4m

Dividing both sides by 3m, we get:

v = (8/3) - (4/3)v

Solving for v, we get:

v = 2 m/s

So after the collision, cart a moves in the negative x direction with a speed of 4 m/s, and cart b moves in the positive x direction with a speed of 2 m/s. We can verify that this satisfies conservation of momentum:

m(4 m/s) + 0 = m(-4 m/s) + 3m(2 m/s)

4m = 4m

This result shows that in a perfectly elastic collision, even though the carts exchange momentum, the total momentum of the system is conserved.

Answer:

y = 6x + 4

Step-by-step explanation:

Find the slope (m) of the line that contains (1, 10) and (0, 4).

Slope = ∆y/∆x = (4 - 10) / (0 - 1) = -6/-1

Slope (m) = 6

Find the y-intercept (b):

y-intercept (b) is 4 because it is the value of y when x = 0.

To write the equation in slope-intercept form, substitute m = 6 and b = 4 into y = mx + b.

Thus:

y = 6x + 4

The possible perimeters are 140 feet, 148 feet and 160 feet.

In order to determine the width that would be used to determine the possible perimeters, the formula for the area would have to be rewritten.

A rectangle is a 2-dimensional quadrilateral with four right angles and two diagonals that bisect each other at right angles.

Area of a rectangle = length x width

Width = area / length

1200 / 40 = 30 feet

1200 / 50 = 24 feet

1200 / 60 = 20 feet

Perimeter of a rectangle = 2 x (length + width)

Perimeter when width is 30 feet : 2(40 + 30) = 140 feet

Perimeter when width is 24 feet : 2(24 + 50) = 148 feet

Perimeter when width is 20 feet : 2 (20 + 60) = 160 feet

it will take you approximately 31.4 seconds  to run around the baseball field at a rate of 9 feet per second.

The time it takes to run around the baseball field will depend on the distance around the field.

Assuming the field is a perfect circle and has a diameter of 90 feet (which is a common size for a baseball field).

The circumference of a circle with diameter 90 feet is:

C = πd = π(90) = 90π feet

To run around the perimeter of the baseball field, you will need to cover a distance of 90π feet.

Using the formula:

time = distance / rate

we can calculate the time it takes to run around the baseball field:

time = (90π feet) / (9 feet/second)

time = 10π seconds

time ≈ 31.4 seconds (rounded to the nearest tenth of a second)

Therefore, it will take you approximately 31.4 seconds (rounded to the nearest tenth of a second) to run around the baseball field at a rate of 9 feet per second.

The value of the polynomial equations are

f ( -10 ) = 20201

f ( 2 ) = 17

f ( 3 ) = 142

Polynomials are mathematical expressions involving variables raised with non-negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non-negative exponentiation of variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the polynomial equation be represented as A

Now , the value of A is

f ( x ) = 2x⁴ + x² - 10x + 1   be equation (1)

Now , when the value of x = -10

f ( -10 ) = 2 ( -10 )⁴ + ( -10 )² - 10 ( -10 ) + 1

On simplifying , we get

f ( -10 ) = 2 ( 10000 ) + 100 + 100 + 1

f ( -10 ) = 20000 + 201

f ( -10 ) = 20201

Now , when the value of x = 2

f ( 2 ) = 2 ( 2 )⁴ + ( 2 )² - 10 ( 2 ) + 1

On simplifying , we get

f ( 2 ) = 2 ( 16 ) + 4 - 20 + 1

f ( 2 ) = 32 - 15

f ( 2 ) = 17

Now , when the value of x = 3 , we get

f ( 3 ) = 2 ( 3 )⁴ + ( 3 )² - 10 ( 3 ) + 1

f ( 3 ) = 2 ( 81 ) + 9 - 30 + 1

Answer: 3,285 Liters

Step-by-step explanation:

In the actual case, all your flushes consume 6 L of water.

You flush 4 times per day, then you consume 4 times 6 L per day, this is:

4*6L = 24 L per day.

And in one year there are 365 days, then in one year you consume:

365*24 L = 8,760 L

Now, if you upgrade the toilet, now per day you use:

one time 6 L and 3 times 3 L

Then in day, you use:

1*6 L + 3*3 L = 6L + 9L = 15L

And in the complete year, you will use 365 times that, which is:

365*15 L = 5,475 L

The amount of water that you would save is equal to the difference between the amount that you use in one year with no upgrade (8,760 L) and the amount that you would use in a year if you upgraded your toilet ( 5,475 L)

The difference is:

D = 8,760 L - 5,475 L = 3,285 L

This means that, in this situation, you would save 3,285 liters of water per year if you upgrade your toilet.

The value of x is -3 and y is 7 for equilateral triangle having x+1, 2x+4 and 3x+y sides.

We can use the fact that an equilateral triangle has equal lengths on each of its three sides to determine the values of x and y.

Given:

First side=x+y

second side= 2x+4

third side=3x+y

An equilateral triangle has three equal sides, hence the following equations can be constructed:

x + 1 = 2x + 4

2x + 4 = 3x + y

Let's tackle each of these equations separately:

x + 1 = 2x + 4

We will subtract x from both sides and subtract 4 from both sides in order to solve this equation:

x + 1 - x = 2x + 4 - x

1 = x + 4

By taking 4 away from both sides, we arrive at:

1 - 4 = x + 4 - 4 , -3 = x

Therefore, x has been determined to be -3.

Now, substitute the value of x in the second equation:

2x + 4 = 3x + y

2(-3) + 4 = 3(-3) + y

-6 + 4 = -9 + y

-2 = -9 + y

y = -2 + 9

y = 7

So, we determined that y has a value of 7.

As a result, the values of x and y are, respectively, x=-3 and y=7

Answer:

Step-by-step explanation:

In an equilateral triangle all sides are equal.

So each of these sides (and their equations are equal to each other.)

To find x - set the first two (as they only involve x) equal to each other and solve.

x + 1 = 2x + 4

x -x + 1 = 2x - x + 4

1 = x + 4

1- 4 = x + 4 - 4

-3 = x

Then substitute -3 for x in the last equation to find y, also setting it equal to one of the other equations.

3(x) + y = x + 1

3(-3) + y = -3 + 1

-9 + y = -2

-9 + 9 + y = -2 + 9

y = 7

so x = -3 and y equal 7
