which of the following lists of ordered pairs is a function?
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
Limone's Lemonade Corp. has a savings plan for its employees. If an employee makes an initial contribution of $1,000.00, the company pays 8% interest compounded quarterly. What is the value of the account after 5 years?
Answer: I don't know
Step-by-step explanation:The annual interest rate is 5%, and the interest accrues at a compounding rate for five years. To calculate the monthly interest, simply divide the annual interest rate by 12 months. The resulting monthly interest rate is 0.417%
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
I'm a little bit confused.
Match the term with the definition.
Triangle A) perpendicular cross section of a cylinder
Rectangle B) shape created when a right triangle is rotated about the y-axis
Circle C) shape created when a rectangle is rotated about the y-axis
Cylinder D) parallel cross section of a sphere
Cone E) perpendicular cross section of a pyramid
Answer:
Step-by-step explanation:
Perpendicular cross section of a pyramid ------- triangle.
Imagine you cut pyramid like that. Height of pyramid would be height of your triangle. and sides of pyramid would be sides of triangle.
Perpendicular cross section of a cylinder ------- rectangle
diameter of a base of cylinder would be one side of rectangle and height of cylinder would be other side of rectangle. (pair of sides)
parallel cross section of a sphere ------ circle
when you cut sphere a side would appear with shape of circle.
shape create.... ----- cylinder.
one side of rectangle would be high of cylinder and other would be radius of it.
last one is cone. If you place right angle in coordinate beginning (0.0) and one of shorter sides to lie on y axis other would be on x axis. when rotated you get cone.
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 help me with this question
Answer:
The answer is X=6 ABC=30 CBD=30
Answer:
x = 21
ABC = 105
CBD = 75
Step-by-step explanation:
3x + 12 + 5x = 180
8x + 12 = 180
8x = 168
x = 21
3(21) + 12 = 75
5(21) = 105

Classify the triangle with the following sides 12, 20, 24
Answer:
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.
Step-by-step explanation:

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 rectangular prism has a volume of 210 cubic meters. The length of the prism is 7 meters and the width is 6 meters. (Please help I'm an idiot and I don't know how to do this
Step-by-step explanation:
so we need to find the height as volume=width×length×height
210=6×7×height
210=42×height
height=210/42=5 meters
please mark brainliest
Answer:The answer is 5 (im assuming you need to find height.)
Step-by-step explanation: The formula to find height v/lw so you multiply 7 times 6 and divide that by 210.

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.
Which statement correctly describes the relationship between the lengths of the sides of the triangle shown below?
A. y squared equals x squared minus z.
B. y squared equals x squared minus z
squared.
C. x squared equals y squared plus z.

Marta believes that the equation of the line of best fit for the scatterplot below is y=5/9x+23/9. Which statement best summarizes why Marta is likely incorrect?
Answer:
A
Step-by-step explanation:
as you can see the y intercept for y=5/9x+23/9
the y intercept is positive (23/9)
and if you drew a line to imitate those points the y intercept(where the line toches the y axis) would be negative.
so A

Simplify 5x - 3(x – 2) – x
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 :)
