Find the momentum of a 23.1 g bullet fired at 621 m/s

If R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.

In ring theory, a commutative ring can be defined as a ring in which the multiplication operation is considered to be commutative in nature.

Let R represent a commutative ring with characteristic K.

Therefore, we have: Kr = 0∀r ∈ R.

Assuming f(x) ∈ R(x)

Then, f(x) would be given by: [tex]a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0=0[/tex]

Also, in some instances ai ∈ R and n ∈ N.

Finally, we would have:

[tex]Kf(x) = K(a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0)\\\\Kf(x) = Ka_n x^n + Ka_{n-1} x^{n-1} +.......+ Ka_1 x^1 +Ka_0\\\\Kf(x) = 0\times x^n + 0\times x +.......+ 0[/tex]

Kf(x) = 0.

Therefore, we can infer and logically deduce that if R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.

By using the fact that the two triangles are similar, we will conclude that the height of the tree is 30ft

If the two triangles are similar, then the quotient between the height and the shadow length must be the same for both of them.

Then if H is the height of the tree we can write:

H/27ft = 5ft/4.5ft

Now we can solve this for H, we will get:

H = (5ft/4.5ft)*27ft = 30ft

So we can conclude that the height of the tree is 30ft.

The answer is 3 out of the variable terms.

The square of a binomial is the sum of the square of the first terms, then multiply the product of the two terms after that the square of the last term.

We have,

3x² + 18x - 8= 0

Move the constants to the right side.

3x² + 18x = 8

Take Factor 3 out of the variable terms.

3(x²+6x)=8

Add 27 to both sides of the equation.

3(x²+6x+9)=8+27

3(x²+6x+9)=35

Write the polynomial as a binomial squared.

3(x+3)²=35

Thus, the answer is 3 out of the variable terms.

Explanation:
oarfish that are shorter than 5 m

Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99

This indicates that the sample mean is lower than the population mean

Therefore,

- 0.99 = (x - 6.5)/1.5

- 0.99 × 1.5 = x - 6.5

- 1.5 = x - 6.5

x = - 1.5 + 6.5

x = 5m

The correct answer is

oarfish that are shorter than 5 m

Based on the calculations, the radian measure of the central angle is equal to 3 radians.

Given the following data:

Arc length = 12 centimeters.

Diameter = 8 centimeters.

Radius = diameter/2 = 8/2 = 4 centimeters.

Mathematically, the length of an arc formed by a circle can be calculated by using this formula:

S = rθ

Using the accrual method, the unearned revenue as of December 31 is $12,000.

Unearned revenue can be defined as the amount a company received from their client for the service they are yet too rendered.

Since the company has received full balance for the services not yet provided. The unearned revenue as of December 31 will be $12,000.

Reason been that the amount that the client paid the company is for a year-long contract, hence the $12,000 represent a prepayment amount for the service the company is yet too rendered to their client

By using the given ratio, we will see that the diagonal measures 50 inches.

First, we know that the ratio between length and width is 16:9, and the length is 43.6 inches, then the width will be:

W = (9/16)*43.6 inches = 24.5 in

Now, the diagonal will be equal to the hypotenuse of a right triangle with catheti of 43.6 in and 24.5 in, by using Pythagorean's theorem we get:

[tex]D = \sqrt{(43.6in)^2 + (24.5in)^2} = 50 in[/tex]

The expression that represents the volume of the prism is 30x² cubic units.

Option D) is the correct answer.

A prism is simply a solid geometric with two polygonal faces laying in parallel planes and with the other faces parallelograms.

Volume of a prism is expressed as;

Volume = base area × height

Also, the base area is expressed using the area of a trapezoid.

Hence,

Base area = (1/2) × h( a + b )

Now, let;

Base area will be;

Base area = (1/2) × h( a + b )

Base area = (1/2) × x( x + 2x )

Base area = (1/2) × 3x²

Base area = 3x²/2

Now volume will be;

Volume = base area × height

Volume = 3x²/2 × h

So, let h be 20 units

Volume = 3x²/2 × 20uniit

Volume = 60x²/2

Volume = 30x² cubic units

Therefore, the expression that represents the volume of the prism is 30x² cubic units.

The system of equations models the paths of the two skate is y = 0.08x²-1.6x+13 and y = 5(x-10)²+5. The correct option is b.

The equation with second degree of an unknown variable x, y, m, n, or p is called the quadratic equation.

David starts at (20, 13) and skates along a path that can be modeled by a quadratic equation with a vertex at (10, 5).

Vertex form of quadratic equation is

y =a (x -h)² +k  where (h,k) is the vertex.

We plug in (10,5) for h and k

y= a (x -10)² +5

Now plug in (20,13) in the above equation and find out 'a'

13 = a (x -10)² +5

13 = a(10)² +5

13 = 100a + 5

Solving for a, we get

a = 0.08

Substitute 0.08 for 'a' then the equation becomes

y= 0.08 (x -10)² +5
