Final answer:
Adjacent sides in a kite are congruent, which can be proven using the definition of a kite, the Reflexive Property of Equality, and the SAS Postulate to show that the two triangles formed by the diagonal are congruent.
Explanation:
To prove that adjacent sides are congruent in a kite, recall the definition of a kite: a quadrilateral with two distinct pairs of adjacent sides that are congruent. Let's name the kite ABCD where AB and AD are one pair of congruent sides, and BC and DC are the other pair. The longer diagonal, which we'll call AC, bisects the kite into two congruent triangles, ∆ABC and ∆ADC. By the definition of a kite, we know that AB = AD and BC = DC.
Now, since AC is the common side in both ∆ABC and ∆ADC, by the Reflexive Property of Equality, AC = AC. With two sides and the included angle (BAC and DAC are congruent as they are both angles cut by diagonal AC) congruent in both triangles, we apply the SAS Postulate (Side-Angle-Side) to prove that the triangles are congruent. Once the triangles are proven congruent, all their corresponding parts are congruent. Therefore, AB = AD and BC = CD, which means the adjacent sides in the kite are indeed congruent.

What is the midpoint of the segment show below
Answer:
Your answer is B. (3, 5/2)
Step-by-step explanation:
The formula to find the midpoint of a segment is
(x1 + x2) / 2 to find the x value
and (y1 + y2) / 2 to find the y value of the midpoint.
To find the midpoint of the segment in the photo, you would do...
-1 + 3 divided by 2, giving you 3 for your x
and then 2+3 divided by 2, giving you 5/2 for your y.
Hope this helps!
Answer:
B
Step-by-step explanation:
the midpoint is based on the average of the two pair of point X1 and X2 as Y1 and Y1 divided by 2, each one. So, if we settle X1 and Y1 as (-1,2) and X2 and Y1 as (7,3)
(X1 + X2)/2 = (-1+7)/2 = 6/2= 3
(Y1 + Y2)/2 = (2+3)/2 = 5/2
so, we get the Answer B (3 , 5/2)

How would adding a score of 0 to this data affect the mean and median game scores? 100, 120, 130, 150
Answer:
100, 120
Step-by-step explanation:
The mean of the given data is 500/4, or 125.
If a score of 0 were added to this data, the mean would be smaller, because we'd have to divide the five scores by 5. The mean would now be 100.
The median of the given data is the average of the middle two scores, that is, of 120 and 130. It's 125.
If we were to add the score of 0 to the four data points, obtaining
0, 100, 120, 130, 150,
the median would be the middle number: 120.
Mean is the average of the data set and mode is the middle terms or average of the middle terms of the data set.
Given information-
The given data consists the values 100,120,130,150.
Total number of values is four.
MeanMean is the average of the given data.

Use technology or a z-distribution table to find the indicated area.
Suppose the distances from the center of a target that arrows strikes are normally distributed with a mean of 20 cm and a standard deviation of 6.4 cm.
Approximately 25% of the arrows are further than what distance from the center?
25% of the arrows are further than approximately 24.32 cm from the target's center.
To find the distance from the center of a target that 25% of arrows are further than, we need to determine the z-score that corresponds to the 75th percentile (since 100% - 25% = 75%).
Using a z-table or technology, we find that the z-score for an area of 0.75 is approximately 0.675.
Next, we use the z-score formula: z = (X - μ) / σ, where µ is the mean (20 cm) and σ is the standard deviation (6.4 cm). Setting z to 0.675, we solve for X:
0.675 = (X - 20) / 6.4
Multiplying both sides by 6.4:
4.32 = X - 20
Adding 20 to both sides gives us:
X ≈ 24.32 cm
Thus, approximately 25% of the arrows are further than 24.32 cm from the center.

Kameron has a combination of quarters and nickles in his wallet. The number of nickels is three times the number of quarters he has. If the total value of the coins is two dollars how many quarters does Kameron have in his wallet?
Answer:
Kameron has 5 quarters in his wallet
Step-by-step explanation:
Let
x----> the number of nickels
y----> the number of quarters
remember that
1 nickel=$0.05
1 quarter=$0.25
we know that
x=3y -----> equation A
0.05x+0.25y=2
Multiply by 100 both sides
5x+25y=200
Simplify
x+5y=40 -----> equation B
Substitute equation A in equation B
(3y)+5y=40
8y=40
y=5 quarters
x=3(5)=15 nickels
Final answer:
By setting up and solving equations based on the value of quarters and nickels and their proportions, we can determine that Kameron has 5 quarters in his wallet.
Explanation:
Finding the Number of Quarters in Kameron's Wallet
To solve Kameron's problem, we can set up two equations based on the given information. Let's define Q as the number of quarters and N as the number of nickels Kameron has. Since we know that the number of nickels is three times the number of quarters, we can express this as N = 3Q.
Next, we calculate the monetary value of the quarters and nickels. Each quarter is worth 25 cents, and each nickel is worth 5 cents. Since the total amount is two dollars, which is 200 cents, we can write the equation 25Q + 5N = 200.
Substituting N with 3Q in the second equation, we get 25Q + 5(3Q) = 200, which simplifies to 40Q = 200. Solving for Q gives us Q = 200 / 40 = 5, so Kameron has 5 quarters in his wallet.

How many cubic blocks of side length 1/6 inch would take to fill a rectangular prism with a length, width, and height of 1/2 cm, 1/6 cm, and 1/2 cm respectively ?
Answer:
9 blocks
Step-by-step:
One way in which to do this problem is to find the volume of the rectangular prism and then divide that by the volume of one cubic block of side length 1/6 inch.
V = (length)(width)(height) = (1/2 cm)(1/6 cm)(1/2 cm) = 1/24 cm³.
Volume of one cubic block of side length 1/6 cm is (1/6 cm)³ = 1/216 cm³.
Dividing 1/24 cm³ by 1/216 cm³ yields 216/24 blocks, or 9 blocks.

Investment in new issues (the stock of newly formed companies) can be both suicidal and rewarding. suppose that of 400 newly formed companies in 2010, only 11 appeared to have outstanding prospects. suppose that an investor had selected two of these 400 companies back in 2010. find the probability that at least one of the investor's companies had outstanding prospects. round to seven decimal places.
Final answer:
To find the probability that at least one of the investor's companies had outstanding prospects out of 400 newly formed companies, we can use the complement rule. The rounded probability is 0.0067747.
Explanation:
To find the probability that at least one of the investor's companies had outstanding prospects, we can use the complement rule. The complement of at least one company having outstanding prospects is that none of the companies have outstanding prospects. Since there are 400 companies in total and only 11 have outstanding prospects, the probability that a single company does not have outstanding prospects is 389/400. Therefore, the probability that both companies do not have outstanding prospects is (389/400)^2. The probability that at least one company has outstanding prospects is 1 - (389/400)^2.
Rounding this to seven decimal places, the probability that at least one of the investor's companies had outstanding prospects is 0.0067747.
Which quadratic equation is equivalent to (x2 – 1)2 – 11(x2 – 1) + 24 = 0?
Answer:
u² – 11u + 24 = 0 where u = (x² – 1)

While playing Monopoly, Sandra has rolled doubles on the dice twice in a row. If she rolls doubles again she must go to the Jail space on the board. Since she is on a "streak," she asks Bill to roll for her. How do Bill's chances of rolling doubles compare to Sandra's?
A) Bill's chances are the same as Sandra's chances.
B) Since she is on a streak, Sandra's chances are higher.
C) Since he hasn't been rolling them, Bill's chances are higher.
D) It depends on whether or not the dice are fair.
Answer:
A bill's chances are the same as Sandra's
Step-by-step explanation:
Bill's chances are the same as Sandra's chances.
To be lucky means to be favored by some unforeseen event. Thus, the fact that a person is lucky or not has no relation to the luck that another person may or may not have. That is, there is no link between the chances of one person and those of another, when they are in the same situation.
Therefore, neither Bill nor Sandra have a different chance of rolling doubles on the next roll of the dice.

If sin theta equal 2/3 and theta is in Quadrant 1, then what value of (tan theta)(cos theta)? Help Please!
A-2/3
B-3 square root 5/5
C-2 square root 5/3
D-square root 5/3
Answer:
Option A. 2/3
Step-by-step explanation:
we know that
If angle theta is in Quadrant 1
then
The value of cos(theta) is positive and the value of tan(theta) is positive
Remember that
tan(theta)=sin(theta)/cos(theta)
In this problem we have
tan(theta)*cos(theta)=[sin(theta)/cos(theta)]*cos(theta)=sin(theta)
therefore
tan(theta)*cos(theta)=sin(theta)=2/3
Final answer:
The value of (tan theta)(cos theta) is 2/3.
Explanation:
To find the value of (tan theta)(cos theta), we can use the given value of sin theta and the fact that sin² θ + cos² θ = 1.
Since the value of sin theta is known to be 2/3, we can square this value to find sin² θ = (2/3)² = 4/9.
Using the identity sin² θ + cos² θ = 1, we can solve for cos² θ by subtracting sin² θ from 1. This gives us cos²θ = 1 - 4/9 = 5/9.
Finally, we can calculate (tan θ)(cos θ) by multiplying tan θ = sin θ/ cos θ = (2/3) / [tex]\sqrt{5/9[/tex] = (2/3) / ([tex]\sqrt{5[/tex]/3) = 2 / [tex]\sqrt{5[/tex] and cos θ = [tex]\sqrt{5/9[/tex]. Therefore, (tan θ )(cos θ ) = (2 / [tex]\sqrt{5[/tex]) * [tex]\sqrt{5/9[/tex] = 2 / 3.

Which transformations to the linear parent function, f(X) = x, give. the function g(x) = 3x-1? Select all that apply.
A. Horizontally stretch by a factor of 3.
B. Vertically stretch by a factor of 3.
C. Shift left 1 unit.
D. Shift down 1 unit.
Answer:
Step-by-step explanation:
B. Vertically stretch by a factor of 3, and
D. Shift down 1 unit.
To determine which transformations were applied to the linear parent function f(x) = x to obtain the given function g(x) = 3x - 1, we need to examine the changes made to the function. Let's analyze each choice:
A. Horizontally stretch by a factor of 3.
A horizontal stretch would mean that the x-values are being multiplied by a constant factor. However, in g(x) = 3x - 1, it's the output values (y-values) that have been multiplied by 3 when compared to f(x) = x. Thus choice A is not correct.
B. Vertically stretch by a factor of 3.
In g(x) = 3x - 1, each output value has been multiplied by 3 relative to the parent function f(x) = x. In other words, y has been replaced by 3y, which causes a vertical stretch or scaling by a factor of 3. So choice B is correct.
C. Shift left 1 unit.
A horizontal shift of the graph would involve an addition or subtraction inside the function's argument (x). For instance, f(x - 1) would indicate a shift to the right by 1 unit, and f(x + 1) would be a shift to the left by 1 unit. Since there is no such term in g(x) = 3x - 1, no horizontal shift has occurred. Choice C is not correct.
D. Shift down 1 unit.
A downward shift is indicated by a subtraction outside the function. In g(x) = 3x - 1, there is indeed a "-1" applied to the entire function, which results in every point on the graph being shifted down 1 unit. Therefore, choice D is correct.
In summary, the transformations applied to f(x) = x to get g(x) = 3x - 1 are:
B. Vertically stretch by a factor of 3.
D. Shift down 1 unit.
If you horizontally stretch the linear parent function f(x) = x by a factor of 2, what is the equation of the new function?
A. g(x) = 1/2x
B. g(x) = x-2
C. g(x) = 2x
D. g(x) = 2-x
To horizontally stretch the linear parent function f(x) = x by a factor of 2, we replace 'x' in the original function with 'x/2'. Therefore, g(x) = x becomes g(x) = x/2 or g(x) = 1/2x.
Explanation:When we talk about stretching the "linear parent function" f(x) = x horizontally by a factor of 2, we are essentially changing the 'x' values of the function, and the equation of the function changes accordingly. When a function is stretched horizontally by a factor of 'b', the new function becomes f(x/b). So, in this case, as the stretch factor is 2, the new function will be f(x/2).
This means that wherever you see 'x' in the original function, you replace it with 'x/2'. So, f(x) = x becomes g(x) = x/2. Therefore, the correct answer to your question is g(x) = 1/2x.

If you cut a cone on the side with an angle that will produce an ellipse-shaped plane.
if you were to cut the cone perpendicularly to its height (as if the double cone on the picture was straight up), you would get a circle as the plane, because it would be a transversal cut of a circular cone.
If you cut it with an angle, you're stretching the circle... so you'll have an ellipse.

Answer:
4, 6, 8
Step-by-step explanation:
The possible degrees of a polynomial function can be determined by observing the highest power of the variable in the polynomial. Each curve or turn in the graph represents a change in direction of the polynomial. The highest number of curves or turns is equal to the degree of the polynomial.
Explanation:The possible degrees of a polynomial function in the graph can be determined by observing the highest power of the variable in the polynomial. The degree of a polynomial is the highest exponent of the variable. For example, if the highest power of the variable is 3, then the polynomial has a degree of 3.
In the graph, we can determine the degree by looking at the x-axis and counting the number of curves or turns. Each curve or turn represents a change in direction of the graph. The highest number of curves or turns is equal to the degree of the polynomial.
For example, if the graph has one curve or turn, then the polynomial has a degree of 1, which means it is a linear function. If the graph has two curves or turns, then the polynomial has a degree of 2, which means it is a quadratic function.

For completing the square our equation should be in the form of [tex]a^2 +2ab + b^2 = (a+b)^2[/tex]
In the given equation we have:
[tex]x^2 +6x -2\\x^2 + 2(x) (?) +(?)^2 = 2\\for\,\, making\,\, 6x\,\, 2*x*3=6x \\so, \,\,we\,\, can\,\, add\,\, and\,\, subtract\,\, (3)^2 \,\,on\,\, both\,\, sides\\x^2 + 2(x) (3) +(3)^2 -(3)^2= 2\\(x+3)^2 -9 =2\\(x+3)^2 =2+9\\(x+3)^2 = 11[/tex]
Correct Option is d [tex](x+3)^2 = 11[/tex]
Please help me out!!!!!
We have three pythagoras:
4² + y² = z²
16² + y² = x²
x² + z² = 20²
Now let's think:
4² + y² = z²
y² = z² - 4²
16² + y² = x²
16² + z² - 4² = x²
x² + z² = 20²
16² + z²- 4² + z² = 20²
2z² = 20² - 16² + 4²
2z² = (2.10)² - (2^4)² + (2²)²
2z² = 2².10² - 2^8 + 2^4
z² = 2.10² - 2^7 + 2^3
z² = 200 - 128 + 8
z² = 208 - 128
z² = 80
z = √80
80 | 2
40 | 2
20 | 2
10 | 2
5 | 5
1
80 = 5.2^4
So
√80 = 4√5
z = 4√5
A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.
Which expression can be used to determine the greatest possible volume of the cardboard box?
(15−x)(22−x)x
(x−15)(x−22)x
(15−2x)(22−2x)x
(22x−15)(15x−22)
Answer:
(15−2x)(22−2x)x
Answer:
Volume of box = (15−2x)(22−2x)x
C is correct.
Step-by-step explanation:
A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.
The dimension of the cardboard must be 15 x 22 because all options has same value.
We have rectangle cardboard with 15 x 22. We cut square from each corner of the board with dimension x.
New length of box = 22 - 2x
New Width of box = 15 - 2x
Height of the box = x
Volume of box is equal to volume of cuboid.
Volume of box = LBH
= (15-2x)(22-2x)(x)
Hence, The correct volume of the box is (15-2x)(22-2x)(x)
