We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because ____
We also know that AC ≅ BC since ___
Using the reflexive property, we see that ____
Therefore, we conclude that △ACO is congruent to △BCO by the _____
Answers
The answers to the dashed parts of the questions to prove that △ACO ≅ △BCO are respectively;
- All radii of the same circle are congruent
- Tangents to a circle that intersect are congruent
- Side CO is congruent to side CO
- SSS congruency theorem
The image of the Triangle and circle has been attached.
Now, from the attached image we can see that;
Point O is the center of the circle and as such AO and BO are both radius of the circle.Thus, it means that AO ≅ BO because; All radii of the same circle are congruent
Since AO and BO are equal, it means that since point C is the intersection point of tangents from points A and B, then we can say that;AC ≅ BC because; tangents to a circle that intersect are congruent.
Reflexive property shows that the length of a side is congruent to itself. Now, in △ACO and △BCO, we see that they share a common side which is CO. Thus, CO is congruent to side CO.We have been able to establish that;
AO ≅ BO
AC ≅ BC
CO ≅ CO
This means all three corresponding sides of both △ACO and △BCO are congruent. Thus, we can conclude that;

Write the quadratic equation whose roots are −4 and 3 , and whose leading coefficient is 1 .
Answers
the roots are
x=-4
x=3
leading coefficient=1
therefore
(1)*(x+4)*(x-3)=0-----------------> x²-3x+4x-12=0
x²+x-12=0
the answer is
x²+x-12=0
Final answer:
To write a quadratic equation with roots −4 and 3 and a leading coefficient of 1, we start with the factored form (x - root1)(x - root2) = 0, substitute the given roots, and simplify to x² + x - 12 = 0.
Explanation:
The question asks us to write the quadratic equation whose roots are −4 and 3, and whose leading coefficient is 1. To find a quadratic equation given its roots, we can use the factored form of a quadratic equation, which is (x - root1)(x - root2) = 0, where root1 and root2 are the roots of the equation.
Given that the roots are −4 and 3, we substitute these values into the equation to get (x - (−4))(x - 3) = 0. Simplifying this, we first eliminate the double negative to get (x + 4)(x - 3) = 0. Multiplying these two binomials gives us the expanded form, which is x² + x - 12 = 0. This is the quadratic equation with roots −4 and 3, and a leading coefficient of 1.

Answers
After buying the cake,
$35 - $18 = $17
Number of balloons he can buy:
17 ÷ 4 = 4.25
So, he can buy 4 balloons.
4 ballons = 4x4 = $16
So amount left = $17 - $16 = $1
The number 4 can fit into the number 17 4 times. 4 x 4 = 16
Therefore, Abit will only have $1 left over.

2. Consider this scatter plot.
(a) How would you characterize the relationship between the hours spent on homework and the test scores? Explain.
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?
(c) What does the number 40 in Part (b) mean in the context of the situation?
Answers
For this case what we see is that we have a scatter diagram, which we can model using a linear trend defining the following variables:
x: number of hours studied.
y: test scores.
The linear relationship would be of the form:
y = mx + b
(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h of homework?
y = 8x + 40
For three hours of study we have that the note would be approximately:
y = 8 * (3) + 40
y = 64
(c) What does the number 40 in Part (b) mean in the context of the situation?
The number 40 means that if you do not devote any study time, then you expect the test score to be 40.
(a) The relationship between hours spent on homework and test scores is a positive correlation, where more homework is generally associated with higher test scores.
(b) The model predicts a score of 64 for 3 hours of homework.
(c) The number 40 represents the baseline test score when no homework is done, according to the model.
Analyzing the Scatter Plot and the Model
(a) Characterizing the Relationship
The scatter plot depicts test scores in relation to the hours of homework. Here’s how we can characterize the relationship:
- Positive Correlation: There is a general upward trend, indicating that as the hours of homework increase, the test scores also tend to increase.
- Strength: The points are not perfectly aligned, but there is a noticeable positive correlation, suggesting that more homework hours are associated with higher test scores.
- Outliers: Most points follow the trend, although there are a few variations. For example, there are a couple of points with low homework hours but relatively high test scores.
(b) Predicting the Score for 3 Hours of Homework
Paul uses the function [tex]\( y = 8x + 40 \)[/tex] to model the relationship, where [tex]\( y \)[/tex] represents the test score and [tex]\( x \)[/tex] represents the hours of homework.
To predict the score for 3 hours of homework:
[tex]\[y = 8(3) + 40 = 24 + 40 = 64\][/tex]
So, the model predicts a score of [tex]\( \boxed{64} \)[/tex] for 3 hours of homework.
(c) Meaning of the Number 40 in the Model
In the context of the situation, the number 40 in the equation [tex]\( y = 8x + 40 \)[/tex] represents the y-intercept. This implies:
- Baseline Score: If a student spends 0 hours on homework, the model predicts that they would score 40 on the test. This serves as a baseline score, indicating the minimum test score a student could achieve without any homework.
Summary
(a) The relationship between hours spent on homework and test scores is a positive correlation, where more homework is generally associated with higher test scores.
(b) The model predicts a score of 64 for 3 hours of homework.
(c) The number 40 represents the baseline test score when no homework is done, according to the model.
Which quotient is equivalent to the mixed number

3
answer in fractions
Answers
Final answer:
To convert 2 2/3 to an improper fraction, multiply the whole number by the denominator and add the numerator, resulting in 8/3. The question lacks details to provide another specific quotient to compare this with. In dividing fractions, multiplication by the reciprocal is used to find equivalent quotients.
Explanation:
To find which quotient is equivalent to the mixed number 2 2/3, we must first convert the mixed number to an improper fraction. A mixed number is composed of a whole number and a fraction, which can be converted into an improper fraction by multiplying the denominator by the whole number and then adding the numerator to this product.
For the mixed number 2 2/3, we multiply the whole number 2 by the denominator 3, giving us 6, and then add the numerator 2, resulting in 8. Therefore, 2 2/3 as an improper fraction is 8/3.
However, without context, it's unclear what other quotient we are being asked to compare with the mixed number 2 2/3. Quotients can refer to the result of any division. Nonetheless, in contexts of dividing fractions, we use the multiplication of the inverse to find equivalent quotients. For example, if dividing by 3/1 (which is the same as dividing by 3), we would multiply by its reciprocal, 1/3.
In cases of conversion factors, we could use a factor that equals 1 to convert units without changing the value. For instance, 1 m / 100 cm is a conversion factor that equals 1, allowing us to convert meters to centimeters without changing the quantity.
Remember, multiplication and division in fractions can be seen as interconnected operations, where dividing by a number is the same as multiplying by its reciprocal.
How is locating -1.5 on a number line the same as locating 1.5 on a number line? How is it different?
Answers
Locating -1.5 and 1.5 on a number line involves measuring 1.5 units from the origin, but in opposite directions; -1.5 is to the left and 1.5 is to the right.
Locating -1.5 on a number line is similar to locating 1.5 in that you measure the same distance away from the origin (0 point), which is 1.5 units. The main difference is the direction in which you measure from the origin. For -1.5, you would move 1.5 units to the left of the origin since negative numbers are represented to the left on a number line. On the other hand, for 1.5, you would move 1.5 units to the right of the origin because positive numbers are placed to the right.
Another perspective of understanding this concept comes from the coordinate system. If you stand on a straight line and choose a point as the origin, moving to the left will give you the negative coordinates, whereas moving to the right will give you the positive coordinates. Regardless of which side you choose, the absolute value of your position from the origin remains the same; only the sign changes to reflect the direction.

Peter is making an "X marks the spot" flag for a treasure hunt. The flag is made of a square white flag with sides of 121212 inches. He will make the "X" by stretching red ribbon diagonally from corner to corner.How many inches of ribbon will Peter need to make the "X"?
Answers
Peter needs approximately 34 inches of ribbon to create an 'X' across his 12-inch square flag, calculated using the Pythagorean theorem to find the length of the diagonals needed for the 'X'.
Explanation:Peter is making an "X marks the spot" flag, which requires calculating the amount of ribbon needed to create the 'X'. The flag is a square with sides of 12 inches each. For an 'X', two ribbons will be needed, each stretching diagonally across the square. The diagonal length of a square can be determined using the Pythagorean theorem, which states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the square has sides of 12 inches, making the formula for the diagonal:
d = √(12^2 + 12^2) = √(144 + 144) = √288 ≈ 16.97 inches.
Since Peter needs two diagonals to form the 'X', the total ribbon length will be 2 × 16.97 inches, which equals 33.94 inches. Therefore, Peter will need approximately 34 inches of ribbon to create the 'X' on his flag.
