The ratio of the net force to the weight of the scallop (F net/Weight) for this motion exists 792.657 Newtons.

The net force exists the vector sum of all the forces that act upon an object. The total of all forces exerted on an object is known as the net force. A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion. When there are a lot of forces acting on a system, the term "net force" is employed.

Given, mass = 29g, speed = 4.10 m/s , Time = 0.15 s

Acceleration (a ) = (final speed - initial speed)/time taken

                           = 4.10 - 0/ 0.15 = 27.333 m/s/s

F = m × a = 29 g × 27.33 m/s

            =  792.657 Newtons

Therefore, the ratio of the net force to the weight of the scallop (F net/Weight) for this motion exists 792.657 Newtons.

The experiment has a binomial distribution just because the product could be or not defective. In this case you have n=26 the number of product that the company will check and you also know that the probability to get a defective one is 3.6%. Now we will proceed as follows, to find the probability of getting 2 or fewer defective products is exactly the same that

We also should notice that

Now,

Then the probability that the company takes 2 or fewer defective products in this batch is

Now, to get the probability that the company find 4 or more defective products we proceed as follows. Since

then

Notice that we only need to find one of these probabilities to get the answer.

Then the probability to get more than 4 defective products is

So if the company finds 5 defective products in this batch the company should stop the production because the probability to get more than 4 defective products is around 1.3%. It means that if you get 5 defective products even with this small probability then we could say that is really probable to get more defective products that those who were expected.

Answer:

43

Step-by-step explanation:

→ Set up an equation

2x + 9 = 0.5 ( 8x - 50 )

→ Simplify

2x + 9 = 4x - 25

→ Minus 4x from both sides

-2x + 9 = -25

→ Minus 9 from both sides

-2x = - 34

→ Divide both sides by -2

x = 17

→ Substitute into AM

2 × 17 + 9 = 34 + 9 = 43

So the initial equation is:

To writte the equation in the standard form we have to make it equal to 0, so we can add 2 in bout sides of the equation:

now, (a) is the number thas goes with the x^2, (b) is the number that goes with the x and (c) is the number that is alon, so:

Now we can substitute this numbers in the quadratic equation:

and finally we can simplify the equation:

By applying sine trigonometry, the angle θ in this right angled triangle is approximately equal to 50 degrees.

In Trigonometry, the law of sines is also referred to as sine law or sine rule and it can be defined as an equation that relates the side lengths of a triangle to the sines of its angles.

In order to determine the value of H, we would apply basic trigonometry. From the information provided about this right angled triangle, we can logically deduce the following parameters:

Therefore, we would use the sine trigonometry to determine the value of H as follows:

Sinθ = Opp/Hyp

0.7071 = 5/H

H = 5/0.7071

H = 7.0711.

Now, we can determine the angle θ in this right angled triangle as follows:

Sinθ = Opp/Hyp

Angle, θ = sin⁻¹(Opp/Hyp)

Angle, θ = sin⁻¹(5/7.0711)

Angle, θ = sin⁻¹(0.7071)

Angle, θ = 44.999 ≈ 50°.

Angle, θ = 50 degrees.

So, A is a correct choice

B is not a correct choice

C is a correct choice

D is a correct choice

E is not a correct choice

Answer:

R=100%

Step-by-step explanation:

Here

Increased population (Pt) = 5.2-2.6 = 2.6

Time = 1987-1952

Rate of increase=?

By formula

Pt = P(1-R/100)^t

2.6=2.6(1-R/100)^35

1=(1-R/100)^35

0^35 = (1-R/100)^35

0=1-R/100

0= 100-R

R=100%

so the average annual population growth rate of the world between 1952and1987 is 100%

The transformation is non rigid

Transformations involve the rotation, reflection, or translation of forms on a coordinate plane. Transformational geometry is a fresh viewpoint on geometry that Felix Klein suggested in the 19th century. The majority of geometric proofs rely on the transformations of objects. Any image in a coordinate plane can be changed using transformations. Applying the transformational laws will help you better understand the graphics in video games. Learn to recognize transformations, comprehend function transformation principles, and investigate the various forms of transformations.

Non-Rigid Transformations actually alter the original object's structure. Scaling, for instance, allows us to make our object larger or smaller. Alternatively, shearing can be used to "push" it up or to the side. In essence, non-rigid transformations allow an object's size to change.

An equation or inequality to model the situation: The distance d to school is 1 1/2 miles more than the distance p to the park is  d = p + 3/2

a statement that the values of two mathematical expressions are equal indicated by the sign =, is known as equation.

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions is known as inequality.

For this situation, we would assume that both the distances i.e 'd' and 'p' are in miles.

It is mentioned that the distance d is more than the distance p by 3/2 miles.

It means that if we add  3/2 miles to the distance 'p' the output will be distance 'd'

The equation for this is as follows :- d = p + 3/2

It also means that if we substract 3/2 miles from distance 'd', the output will be distance 'p'

The equation for this is as follows :- p = d - 3/2

But we are asked in the situation that distance d is more than than the distance 'p'.

Therefore , an equation or inequality to model the situation: The distance d to school is 1 1/2 miles more than the distance p to the park is d = p + 3/2.
