Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle.
Prove: △ACO ≅ △BCO
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 _____
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;
△ACO is congruent to △BCO by the "SSS Congruency theorem"

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"?
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.

B) 1.6 × 102 bushels per acre
C) 1.6 × 103 bushels per acre
D) 2.82 × 106 bushels per acre
E) 1.6 × 101 bushels per acre
The average amount of corn produced per acre represented in scientific notation can be found using the below formula:
[tex] The \;average\; amount\; of\; corn\; per\; acre=\frac{Bushels \; of\; corn\; produced\; in\; farm}{Area\; of\; farm\; in\; acres} [/tex]
We are given:
[tex] Area \; of\; FARM\; land= 4.2 \times 10^2 \; acres\\ \\ Amount \; of\; corn\; produced=6.72\; \times \; 10^4 \; bushels [/tex]
Substituting the above information in the formula, we get...
[tex] The \; Average\; amount\; of\; corn=\frac{6.72 \times 10^4}{4.2 \times 10^2} \\ \\ \frac{6.72}{4.2} \times \frac{10^4}{10^2}\; =\; 1.6 \times 10^{4-2}\; =\; 1.6 \times 10^2\\ \\ [/tex]
Conclusion:
[tex] The \; Average \; amount\; of \; corn \; is\; 1.6 \times 10^2 \; Bushes\; per\; corn [/tex]

At the beginning of the day, stock XYZ opened at $3.15. At the end of the day, it closed at $2.87. What is the rate of change of stock XYZ?
Answer:
-8.9%
Step-by-step explanation:
Answer:
The rate of change is - 8.89 %.
Step-by-step explanation:
Given,
The opening price = $ 3.15,
While closing price = $ 2.87,
Now,
[tex]\text{The rate of change}=\frac{\text{closing price-opening price}}{\text{opening price}}\times 100[/tex]
[tex]=\frac{2.87-3.15}{3.15}\times 100[/tex]
[tex]=\frac{-0.28}{3.15}\times 100[/tex]
[tex]=-\frac{28}{3.15}=-8.8889\%\approx -8.89 \%[/tex]

Actual 12 14 14 13 16 14
Predicted 8 15 15 12 17 15
Residual 4 −1 −1 1 −1 −1
Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.
Answer: No, the equation is not a good fit because the sum of the residuals is a large number.
Step-by-step explanation:
A residual is the difference on the scatter plot between the actual y-value and the predicted y-value from the regression line equation.
It is the vertical distance from the actual plotted point to the point on the regression line.
The residual is positive then the data point is above the graph.
The sum of the given residual values = [tex]4+(-1)+(-1)+1+(-1)+(-1)=1[/tex]
Since, the sum of the residuals is greater than 0.
Therefore, The equation is not a good fit .
Answer:
A. No, the equation is not a good fit because the sum of the residuals is a large number.

Which expression is equivalent to(3m^-2 n)^-3/6mn^-2? Assume
To simplify the expression (3m⁻² n)⁻³/6mn⁻², follow the steps: apply the negative exponent rule, simplify by multiplying the exponents, and rearrange and combine like terms if necessary.
Explanation:To simplify the expression (3m-2 n)-3/6mn-2 , let's break it down step by step:
Step 1: Apply the negative exponent rule. To do this, we can move any term with a negative exponent from the numerator to the denominator or vice versa. In this case, the term m-2 can be written as 1/m2.
Step 2: Simplify the expression by multiplying the exponents. The exponents in the expression can be added since they have the same base (m).
Step 3: Simplify further by rearranging and combining like terms if necessary.
Putting it all together, the expression is equivalent to (1/3m4n6)1/6mn-2.
which cream cheese has the lowest price per ounce?
A: $2.59 for 6oz
B: $2.89 for 8 oz
C: $4.29 for 12 oz
D: $5.29 for 14 oz
Answer:the correct answer is $4.29 for 12 oz.
Step-by-step explanation:
The cream cheese which has the lowest price per ounce is the one which is $4.29 for 12 oz. Thus, the correct option is C.
What is Ounce?The ounce is any of the several different units of mass, weight or volume and it is derived almost unchanged from the uncia, unit of measurement.
The ounce is 1/16 avoirdupois pound. This is the United States customary and British imperial ounce. Ounce is primarily used in the United States to measure packaged foods and food portions, areal density of fabric and paper, boxing gloves, and so on, but it is sometimes also used elsewhere in the Anglosphere.
The price for per ounce of different cream cheese will be:
a. 2.59/ 6 = 0.431
b. 2.89/ 8 = 0.361
c. 4.29/ 12 = 0.357
d. 5.29/ 14 = 0.377
Therefore, the cream cheese which has the lowest price per ounce is the one which costs $4.29 for 12 oz.
Therefore, the correct option is C.
