Plot the points in the coordinate plane. Then determine whether AB and CD are congruent. Explain
Answer:
AB and CD are congruent.
Step-by-step explanation:
Given points:
A = (4, 1)B = (2, 6)C = (-2, 2)D = (-4, -3)To determine if AB and CD are congruent, calculate the length of the two lines using the distance formula.
[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]
[tex]\begin{aligned}\implies AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-4)^2+(6-1)^2}\\& = \sqrt{(-2)^2+(5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]
[tex]\begin{aligned}\implies CD & = \sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\& = \sqrt{(-4-(-2))^2+(-3-2)^2\\& = \sqrt{(-2)^2+(-5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]
Therefore, as AB = CD, we can conclude that AB and CD are congruent.
Solve the equation, 1/3|x−8|=10. Select each correct answer. Responses x=−30 x equals negative 30 x=−22 x equals negative 22 x=103 x equals 10 over 3 x = 8 x, = 8 x = 30 x, = 30 x = 38

The words related to the mathematical operation of division are:
Separate.Cut.Quotient.Renumber.Which are the words related to divisions?
A division between two numbers tells us how many times the denominator can be fit into the numerator (the numerator is the number being divided by the denominator).
The "math word" used for divisions is "quotient"
The quotient between two numbers is equivalent to say the "outcome of the division between two numbers"
So that is one of the correct options.
Other correct option is "separate"
Like in the word problem example "3 friends separate evenly 9 candy between them". Here we have a division.
Similar, "cut" is also related to divisions.
The word problem "A piece of wire of 1 meter is cut into 3 pieces, how long is each one?"
Again, this is a division problem.
The last correct option is renumber, which is mostly a way of rewritting a number, but it uses divisions to do it.

At what time is the acceleration 0? (Round your answer to two decimal places.)
When t=0 and t=6s is the time at which the particle have a velocity of 25 m/s and t=3s is the time when acceleration is 0.
What is Acceleration?a vehicle's capacity to gain speed within a short time
Given s = t^4 − 4t^3 − 36t^2 + 25t
v=d/dt(s)=4t^3-12t^2-72t+25
the particle have a velocity of 25 m/s
So 4t^3-12t^2-72t+25=25
=4t^3-12t^2-72t
=4t(t^2-3t-18)=0
t=0 and
t^2-3t-18=0
(t+3)(t-6)=0
So t=0, t=-3 and t=6
As time>=0, So t=0 and t=6.
Now we required to find acceleration,
Accelaration=d/dt(v)
=d/dt(4t^3-12t^2-72t+25)
=12t^2-12t-72
t=12±√144-4(12)(-72)/24
t=12±60/24
t=12+60/24=3 and 12-60/24=-2
So t=3s
Therefore t=0 and t=6s is the time at which the particle have a velocity of 25 m/s and t=3s is the time when acceleration is 0.

Antonio will save $113.4 after calculating using mensuration and buying from Pets Galore instead of Healthy pets.
As per the question statement, Antonio needs to buy 150 pounds of dog food for the local dog shelter. Healthy Pets, sells dog food in 50-pound bags for $85.95 per bag and Pets Galore sells one bag for $48.15
We are supposed to calculate the amount of money saved by Antonio if he buys 150 pounds of dog food from Pets Galore instead of from Healthy Pets.
Using concept of mensuration,
Quantity of dog food in one bag = 50 pounds
Quantity required of dog food = 150 pounds
Therefore number of bags required = 150/50 = 3
Price of dog food at Pets Galore per bag = $48.15
Total money to be paid to Pets Galore for 3 bags = $48.15*3 = $144.45
Total money to be paid to Healthy Pets for 3 bags = $85.95*3 = $275.85
Therefore money saved = $275.85 - $144.45 = $113.4
Mensuration: Act of measuring or measure. Here we are measuring the amount of money saved using this concept and applying simple mathematical formula.

Construct a table of values for the following functions using the integers from -4 to 4.
a. F(x)=6/x-2
b. r(x)=6x+12/x²-4
These are our two tables of values for the following functions using the integers from -4 to 4.
What is function?A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given:
The given functions using the integers from -4 to 4 are
a. F(x)=6/x-2b.
r(x)=6x+12/x²-4
According to given question we have
f(x) = 6/x - 2
Now we just need to evaluate the function in all the given points:
a) f(x) = 6/x - 2
Now we can put the value
f(-4) = 6/(-4) - 2 = -3/2 - 4/2 = -7/2
f(-3) = 6/-3 - 2 = -4
f(-2) = 6/-2 - 2 = -5
f(-1) = 6/-1 - 2 = -8
f(0) is undefined
f(1) = 6/1 - 2 = 4
f(2) = 6/2 - 2 = 1
f(3) = 6/3 - 2 = 0
f(4) = 6/4 - 2 = -1/2
b. r(x)=6x+12/x²-4
Now we can put the value
r(-4) = 6(-4)+12/(-4)²-4=-27.25
r(-3) = 6(-3)+12/(-3)²-4=-20.66
r(-2) = 6(-2)+12/(-2)²-4=-13
r(-1) = 6(-1)+12/(-1)²-4= 2
r(0) = 6(0)+12/(0)²-4= ∞
r(1) = 6(1)+12/(1)²-4 =14
r(2) = 6(2)+12/(2)²-4=11
r(3) = 6(3)+12/(3)²-4 =15.33
r(4) = 6(4)+12/(4)²-4=20.75
Therefore, these are our two tables of values for the following functions using the integers from -4 to 4.

How to graph a quadratic equation
In accordance with algebra fundamental theorem, we can construct a quadratic equation by knowing the locations of at least three points on Cartesian plane. Herein we find a quadratic equation in vertex form, whose formula is described below:
y - k = C · (x - h)²
Where:
h, k - Coordinates of the vertex.C - Vertex constant.By using this expression, we can find the locations of the vertex and intercepts of the parabola. Now we proceed to find all the required information:
Vertex
y = (x + 5)²
(h, k) = (- 5, 0)
x-Intercepts
(x + 5)² = 0
x = - 5
y-Intercept
y = (0 + 5)²
y = 25

over the time period.
After retirement the IRA will contain S
(Do not round until the final answer. Then round to the nearest cent as needed.)
The amount that would be in th IRA when he retires at age 65 is $21,932.15.
How much would be in the account?An annuity is a series of payment that is made over a period of time. In this question, the annuity is monthly which lasts for 47 years (65 - 18). An ordinary annuity is when the payments are made at the end of the period. An annuity due is when the payment is made at the beginning of the period.
The amount deposited increases by the amount you put in it every month and by the interest rate the account accrues. The account earns an APR, this means that interest would be compounded yearly.
Total amount of deposits = amount deposited monthly x number of months in a year x number of years
$60 x 12 x 47 = 33,840
The formula that can be used to determine the future value of the account in 47 years is:
Monthly deposit x annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = interest rate = 7% / 12= 0.583%n = number of periods = 12 x 47 = 564$60 x [{(1.00583)^564 - 1} / 0.07] = $21,932.15
