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.

Find the value of each variable and the measure of each labeled angle (2x) (3x-42)
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.
What are vertical angles?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.

The solution is, Option B Negative ,as time passes, speed decreases.
What is Correlation?Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.
here, we have,
Description of the Graph
1. The Relation between , Speed and time is depicted on the graph.
2. Minute = x coordinate
Miles per hour= y coordinate
The points shown on the graph , describing the relationship are, (5,15),(10,13.8),(15,11),(20,10),(25,9.8).
There are two types of Correlation
Positive Correlation= With Increase in x value, y value also increases or vice versa, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases or vice versa, we call it negative correlation.
As you can see from the points plotted on the graph ,with increase in x value , y value decreases.
So it is negative correlation.
As, time passes, Speed Decreases, So it is a Negative Correlation.
Option B Negative ,as time passes, speed decreases.

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(-4.2w-7x-5.4)
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

Please do number 18 for me.
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

Explain how feel about trump being impeached a second time this time for the mobs action
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.

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

g(1)=0
g(n)=g(n-1)+n
g(2)=????
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
