Complete Question:

A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 Seconds.

a. what acceleration is imparted to the paper?

b. if the mass of the paper is 0.003 kg, what force does the boxer exert on it?

c. how much force does the paper exert on the boxer?

Answer:

a. Acceleration = 454.55m/s².

b. Force = 1.36N

c. Force = -1.36N

Step-by-step explanation:

Given the following data;

Final velocity = 20m/s

Time = 0.044 seconds.

Since the paper is at rest, we know that it's initial velocity is equal to 0m/s.

a. To find acceleration;

Mathematically, acceleration is given by the equation;

[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]

Substituting into the equation, we have;

[tex]a = \frac{20 - 0}{0.044}[/tex]

[tex]a = \frac{20}{0.044}[/tex]

Acceleration = 454.55m/s²

b. To find the force exerted by the boxer;

Mass = 0.003kg

Force = mass * acceleration

Force = 0.003 * 454.55

Force = 1.36N

c. To find the force exerted by the paper;

According to Newton's third law of motion which states that, for every action there is an equal and opposite reaction. Therefore, the paper exerts an equal but opposite force on the boxer.

Force = -1.36N

Step-by-step explanation:

angle S + angle W + angle STW = 180

(7x + 6) + (7x + 1) + angle STW = 180

So angle STW = 180 - (7x + 6) - (7x + 1)

angle STW + angle STP = 180 (straight angle = 180)

180 - (7x + 6) - (7x + 1) + angle STP = 180

angle STP = 180 - 180 + (7x + 6) + (7x + 1)

= 7x + 6 + 7x + 1

= 14x + 7

15x = 14x + 7

x = 7

angle STP = 15x = 15(7) = 105

Answer:

Isosceles triangle.

Step-by-step explanation:

On the basis of the lengths of the sides of a triangle, below are three types of triangles.

Equilateral triangle: The triangle in which the lengths of all sides are equal.

Isosceles triangle: The triangle in which the lengths of any two sides are equal.

scalene triangle: The triangle in which the lengths all the three sides are different.

Here, the length of the sides are 24 24 and 4.

Since, two sides are equal in length.

Hence, it is an Isosceles triangle.

Answer: 4.2*w + 7*x + 5.4

Step-by-step explanation:

Here we need to remember how the product of different signs works, here is the rule:

(+)*(+) = (+)

(+)*(-) = (-)

(-)*(+) = (-)

(-)*(-) = (+)

Now we want to distribute the negative sign in the equation:

"-(-4.2w-7x-5.4)"

We can write this as:

-(-4.2w-7x-5.4) = (-1)*(-4.2w-7x-5.4)

Now we can distribute the "-1"

Then we get:

(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4)

We have 3 cases where we need to use the "(-)*(-) = (+)" rule, then we get:

(-1)*(-4.2w) + (-1)*(-7x) + (-1)*(-5.4) = 4.2*w + 7*x + 5.4

Answer:

x - 2

Step-by-step explanation:

distributive property first since you stick with parentheses first (PEMDAS)

so 3x - 6 is what it would be.. then you would want to think of the equation as 5x - 3x - 2 - x. seems somewhat complicated but to others not so much.

Next you’re gonna just want to subtract, but you should probably make the problem easier so you can just subtract across right? it’d be 5x - 3x - x - 2. that way all the x variables are together and anything else is separate.

5x - 3x is 2x - x or - 1x is x or 1x.

i think just using the variable x for it being 1 is easier so now we have the problem x - 2.

anything else? nope! that’s the simplified equation.

hope that i was able to help :)

Answer:

Trump needed to be impeached for his words and actions that led to the mob action.

He created the atmosphere of distrust in the election results by making statements that the only way he could lose the election would be if there was massive fraud. Then, when he lost the election, he used that as "proof" that there had been fraud. That is distorted logic.

Many of Trump's followers believed his claim that he had won the election, and they came to Washington DC for the rally to support him. Many of them were prepared to commit acts of violence against the members of the Congress, the senators and Vice-president Pence to prevent them from counting the votes from the Electoral College. The Trump followers believed that he could continue as president if they literally fought for him.

They invaded the Capitol and terrorized the elected officials. People died in the attack. And it could have been much worse.

None of that would have happened if not for Trump deluding them, inviting them, and encouraging them.

He must be held accountable.

Step-by-step explanation:

Opinions matter. People should form them based on facts. Facts can be verified and checked. There is a difference between assertions and facts. People can make assertions that are not true. Maybe they are mistaken. Maybe they were confused. People can admit their mistakes and correct the errors.

Some assertions are delusional: the person who makes the statement actually believes something that is not based on facts, and cannot be convinced otherwise.

Some assertions are lies, spoken to deceive others; they deliberately hide or distort the truth.

Answer:

D

Step-by-step explanation:

to be a function you cannot have different y values for the same x, in B for example when x = 3 you have two different values for y (3,7) and (3,8)

D is the only choice where each value of x only has one value for y

Step-by-step explanation:

Head opposite angles

2x= 3x-42

x= 42°

the angles are 84°

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles. The value of x is 42 and the measure of the two given angles is 84° each.

Each of the pairs of opposite angles made by two intersecting lines is called a pair of vertical angles.

The two of the given angles are vertically opposite angles, therefore, the measure of the two given angles will be the same.

(2x)° = (3x - 42)°

2x = 3x - 42

Subtract 2x from both sides of the equation and add 42 to both sides of the equation,

2x - 2x + 42 = 3x - 42 - 2x + 42

42 = 3x - 2x - 42 + 42

42 = x

Therefore, the value of x is 42. Now, the measure of each angle can be written as,

(2x)° = 2(42) = 84°

(3x - 42)° = 3(42) - 42 = 84°

Hence, the value of x is 42 and the measure of the two given angles is 84° each.

Answer:

C

Step-by-step explanation:

We can use the pythagorean theorem (A^2 + B^2 = C^2) To solve this question.

For answer A, we add 6^2 (36) and 8^2(64) to get 10^2 (100). This is a right triangle.

For question B, we add [tex]\sqrt{3}[/tex] ^2 (3) and [tex]\sqrt{8}[/tex]^2 (8) to get [tex]\sqrt{11}[/tex]. This is a right triangle.

For question C, we add 3^2 and 5^2 to get [tex]\sqrt{34}[/tex]. This is not a right triangle.

Answer:

The correct answer is: It has only one real solution, x=-2. This is because the two functions intersect at only that point.

If g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2

The given relationship is:

g(1) = 0

g(n) = g(n-1) + n

g(2) = ?

Since g(1) is already known

g(2)  =   g(1)  +  2

Note that g(1) = 0

Substitute g(1) = 0 into g(2)  =   g(1)  +  2

g(2) = 0  +  2

g(2)  =  2

Therefore, if g(1) = 0 and g(n) = g(n-1) + n, then g(2) = 2
