Given: AB = CD
Prove: AC = BD
What reason can be used to justify statement 4 in the proof above?
the reflexive property the symmetric property the transitive property the segment addition property
Step-by-step explanation:
To prove that AC = BD, we can use the symmetric property. The symmetric property states that if two quantities are equal, then their opposites are also equal.
In this case, we are given that AB = CD. Since AB and CD are opposite quantities (they are the lengths of the diagonals of a rectangle), we can use the symmetric property to conclude that AC = BD.
Therefore, the reason that can be used to justify statement 4 in the proof is the symmetric property.
3-quart carton of milk costs $4.92. What is the price per cup?
Answer:
The price per cup would be 0.41 cents.
Step-by step explaination:
Answer:
$0.41
Step-by-step explanation:
To find the price per cup of milk, we first need to know how many cups are in a 3-quart carton.
1 quart is equivalent to 4 cups, so a 3-quart carton contains:
[tex]\sf 3\;quarts=3 \times 4 \;cups= 12\;cups[/tex]
Now, we can calculate the price per cup by dividing the total price by the number of cups:
[tex]\begin{aligned}\textsf{Price per cup} &= \dfrac{\textsf{Total price}}{\textsf{Number of cups}} \\\\&=\sf \dfrac{\$4.92}{12}\\\\&=\sf \$0.41\end{aligned}[/tex]
Therefore, the price per cup of milk is $0.41.

The inverse function for this problem is defined as follows:
P^(-1)(x) = square root of (x + 100/5), x ≥ -100.
How to obtain the inverse function?The function in this problem is defined as follows:
P(x) = 5x² - 100, x ≥ 0.
In which P(x) is the profit earned when x tamales are sold.
To obtain the inverse function, first we exchange the variable y = P(x) and x are follows:
x = 5y² - 100
Then the variable y must be isolated as follows:
5y² = x + 100
y² = (x + 100)/5
y = square root of (x + 100/5).
The domain must be the same domain of the square root function, that does not accept negative values hence:
P^(-1)(x) = square root of (x + 100/5), x ≥ -100.
This means that the first option is correct.

At the cease of the second one year, you may have $110.25.
Now,
h=8(1+r/100)^t
h=8(1+14/100)^t
h=8(114/100)^t
h=8(1.14)^t inches

At a basketball game, a team made 59 successful shots. They were a combination of 1- and 2-point shots. The team scored 99 points in all. Write and solve a system of equations to find the number of each type of shot.
Answer:
Step-by-step explanation:
Let x be the number of 1-point shots and y be the number of 2-point shots. We know that the total number of shots is 59 and the total number of points is 99. We can write these two equations as follows:
x + y = 59
1x + 2y = 99
To solve this system of equations, we can use substitution. We can solve the first equation for y and substitute the result into the second equation:
y = 59 - x
1x + 2(59 - x) = 99
1x + 118 - 2x = 99
-x = -19
x = 19
Now that we know the value of x, we can substitute it into the first equation to find the value of y:
y = 59 - 19 = 40
Therefore, the team made 19 1-point shots and 40 2-point shots.
the equation is given: a^2x-a=ax. for some values of a this equation has a unique solution. Solve the equation for these values of a
The solution of the equation for values of a is 1/(x - 1)
How to solve the equation for these values of aFrom the question, we have the following parameters that can be used in our computation:
a^2x - a = ax
Rewrite properly as
a²x - a = ax
Divide through by a
So, we have
ax - 1 = x
Collect the like terms
ax - x = 1
Factor out x
This gives
a(x - 1) = 1
Divide both sides by x - 1
a = 1/(x - 1)
Hence, the solution is 1/(x - 1)

The variable that researchers are trying to explain or predict is called the response variable. It is also sometimes called the dependent variable because it depends on another variable.
Variables used to explain or predict a response variable are called explanatory variables.
The students want to predict age using their height, so the explanatory variable is height and the response variable is age.
The values of an ordinal variable have a meaningful order. For example, an education level (with possible values of high school, bachelor's degree, and graduate degree) can be an ordinal variable.

Tommy i buying ued book the price of the book are 180. He ue the 30% off tudent dicount and there i a 4 % ale tax. What i the total price
Using percentages we know that the total price of the book that Tommy will pay is $131.04.
What is the percentage?
In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.
Although "pct," "pct," and occasionally "pc" are also used as abbreviations, the percent symbol "%" is most usually used to denote it.
A% is a number that has neither dimensions nor a defined unit of measurement.
For instance, if you properly answered 75 out of 100 questions on a test, you would have received a 75% grade (75/100).
So, we know that the price of the book is 180.
Sales tax is 4%. So, the total price:
180/100 * 4 = 7.2$ ⇒ $187.2
Now, there is a 30% discount:
187.2/100 * 30 = $56.16
⇒ 187.2 - 56.16 = $131.04
Therefore, using percentages we know that the total price of the book that Tommy will pay is $131.04.

Radius=a straight line extending from the center of a circle or sphere to the circumference or surface: The radius of a circle is half the diameter. the length of such a line.
The radius of convergence of the sum of the two series will be 5.
sigma (cnxn + dnxn) = sigma cnxn + sigma dnxn, and if both the series on the right-hand side converge.
The LHS converges for values of x on which both the series on the RHS converge. Hence, the LHS will converge on the intersection of the convergence of the two RHS series.
( if 5 < |x| < 6, the second series will converge, but the first will not.)
The series sigma cnx9n has radius of convergence R raised to the power 1/9.The series sigma cnxn has radius of convergence R. This means that it converges for |x| < R.The series sigma cnx9n can be written as sigma cn(x9)n
