Answer:

Given: QR = QS (by given)

We are to prove: LS = ZR

Proof:

Since QR = QS, by the SAS (Side-Angle-Side) congruence postulate, we know that triangle QRS is congruent to triangle QSZ (both have two equal sides and included angle).

By the AAS (Angle-Angle-Side) congruence postulate, we know that if two angles of one triangle are congruent to two angles of another triangle, and the included side is congruent, then the two triangles are congruent.

Therefore, by using AAS congruence, we can say that triangle QRS is congruent to triangle QSZ.

By the CPCTC (Corresponding parts of congruent triangles are congruent), we know that if two triangles are congruent, then their corresponding sides are congruent.

Therefore, LS is congruent to ZR.

Therefore, we have proved LS = ZR

Note: The above proof uses the properties of congruence of triangles, if the student is not familiar with this, it might be challenging for them.

In the given question, according to state census information, the population of LaVergne, Tennessee in 2012 was 33.777 x [tex]10^3[/tex].

The population of Murfreesboro, Tennessee in 2012 was 1.14038 x [tex]10^5[/tex].

(a) We have to write the Population of LaVergne, Tennessee in Standard Form.

The population of LaVergne, Tennessee in 2012 = 33.777 x [tex]10^3[/tex]

The population of LaVergne, Tennessee in 2012 = 33.777 x 1000

Now multiplying

The population of LaVergne, Tennessee in 2012 = 33,777

(b) We have to find the combined population of both cities.

The population of LaVergne, Tennessee in 2012 = 33,777

The population of Murfreesboro, Tennessee in 2012 = 1.14038 x 100,000

The population of Murfreesboro, Tennessee in 2012 = 114038

The combined population of both cities = The population of LaVergne, Tennessee + The population of Murfreesboro, Tennessee

The combined population of both cities = 33,777 + 114038

The combined population of both cities = 147,815

Out of 400 band-aids, 200 were used yesterday. Therefore, the percentage of band-aids used yesterday is 50%.

You started with 4 boxes × 100 band-aids per box

= 400 band-aids.

You ended with 2 boxes × 100 band-aids per box

= 200 band-aids

So you used

400 band-aids - 200 band-aids = 200 band-aids yesterday.

To find the percentage of band-aids used, you can divide the number of band-aids used by the total number of band-aids you started with and multiply by 100:

= (200 band-aids / 400 band-aids) × 100

= (1/ 2) × 100

Answer: 72 in = 182.88cm

Step-by-step explanation:

The position number for term 47 is 269.

This is an arithmetic sequence since each term has a common difference. Let us test it.

The difference between 1st and 2nd terms is

-7 + d = -1

d = -1 + 7

  = 6

Now we check the difference for term

The difference between 3rd and 4th terms is

5 + d = 11

d = 11 – 5

  = 6

So the difference is the same so we can apply a common equation for arithmetic sequence

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )

Where :

[tex]a_{n}[/tex] = number at term n

[tex]a_{1}[/tex] = first number of sequence

d = difference for each number sequence

n = term

From the question, we need to find the number at position term 47

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] + d ( n - 1 )

[tex]a_{47}[/tex] = -7 + 6 ( 47 - 1 )

    = -7 + 6 ( 46 )

2y - z + z^2 is an algebraic expression. It represents a mathematical operation that includes three different terms: 2y, -z and z^2. It can be simplified depending on the context and the values of y and z.

In the given expression, 2y is the coefficient of y, which is multiplied by y. -z is subtracted from 2y and z^2 is added to the result.

In order to simplify this equation, you could combine like terms, which means combining the same variable or powers of the same variable with each other.

This expression does not have any like terms, so it can't be simplified anymore.

It can be evaluated by replacing y and z with specific values and then performing the mathematical operations in the given order.

The ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.

The amount of water, sucrose, and the saline solution used can be expressed as a ratio in its simplest form by finding the greatest common divisor (GCD) of the three quantities and dividing each by it.

1l of water = 1000 ml of water.

Let's find the GCD of the three quantities:

GCD(199,271,1000) = 1

So we can express the amount of water, sucrose, and saline solution needed as a ratio in its simplest form by dividing each of the three quantities by 1

Water : Sucrose : Saline solution = 1000 : 199/1 : 271/1 = 1000:199:271

Hence, the ratio of water, sucrose, and saline solution needed is 1000:199:271 in its simplest form.

The wood fragment is 11,460 years old by C-14 dating if only 25% of the amount the tree had when it was alive is left.

The process of carbon-14 dating can be used to determine the age of an organic material such as wood. Carbon-14 is a radioactive isotope of carbon that is present in all living organisms. When an organism dies, the carbon-14 begins to decay at a known rate, and the amount of carbon-14 in the material decreases over time. By measuring the amount of carbon-14 remaining in a sample, it is possible to determine how long ago the organism died.

If the analysis shows that the C-14 has been reduced to 25% of the amount the tree had when it was alive, it means that 75% of C-14 has decayed, and the material is therefore 75% of its way through its radioactive decay.

Carbon-14 has a half-life of 5,730 years, which means that after 5,730 years, half of the carbon-14 in a sample will have decayed. To find the age of the wood fragment, you would need to multiply the sample's decay percentage (75%) by the material's half-life (5730 years) to get the number of years that have passed.

[tex]t = \frac{5730\ ln(0.25)}{-ln2}[/tex]

Where t is the number of years to decay to 25%.

t = 5730 × ( ln(4)/ ln(2))

The maximum deflection of the simply supported beam is given by:

Maximum deflection = (5PL^3)/(384EI)

where P is the load applied to the beam, L is the length of the beam, E is the Young's Modulus of the beam material, and I is the moment of inertia of the beam.

Substituting the given values into the equation, we get:

Maximum deflection = (5*P*L^3)/(384*200*10^9*39.9*10^6)

The velocity of the trainee is 94.2/m m/s and 0.15 x m rev/s.

The centripetal force (Fc) felt by the trainee can be calculated using the following equation:

Fc = mv2/r

Where m is the mass of the trainee, v is the velocity and r is the radius of the circle.

Therefore, the velocity (v) required to produce a centripetal force of 7.85 times the mass of the trainee can be calculated as follows:

v =√(Fc x r/m)

=√(7.85 x 12.0/m)

=√(94.2/m)

For a given mass, the velocity is therefore 94.2/m m/s.

Converting to revolutions per second (rev/s), the velocity can be calculated as follows:

v = (2πr)/T

= (2π x 12.0)/(94.2/m)

= (14.14 x m)/94.2

= 0.15 x m rev/s

Therefore, the velocity of the trainee is 94.2/m m/s and 0.15 x m rev/s.

From the given line equation, the closet point to the origin is (-6/5, 3/5).

Here we have given that the point on the line y=2x+3 that is closest to the origin.

As we all know that the closest point from origin will be the perpendicular distance from origin to the line.

Here we need to find an equation of the perpendicular from (0,0) on y = 2x + 3.

As we all know that the standard form of the equation is in slope-intercept form is written as,

=> y = mx + c

While we comparing this with the given equation, then we get the value of the Slope that is m = 2 and the Slope of the perpendicular is calculated as,

=> - (1/m) = -1/2

Now, we have to write the equation of the perpendicular is found by using the formula,

=> (y - y1) = m (x - x1)

Apply the value on the equation, then we get,

=> y - 0 = (-1/2) (x - 0)

=> y = (-1/2)x

therefore, the resulting perpendicular equation is written as,

=> 2y + x = 0 ----------------(2)

When we solving (1) and (2), then we get,

=> 5y = 3

Therefore, y = 3/5

And the value of x is calculated as

=> x + 2(3/5) = 0

=> x = -6/5

Where a is the slope (also known as the rate of change, this is what we are looking for here) and b is the y-intercept.

If the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)
