We would find the area of each circular portrait by applying the formula for finding the area of a circle which is expressed as
Area = pi * radius^2
For the large portrait, diameter = 18
Radius = diameter/2 = 18/2 = 9 in
Area = pi * 9^2 = 81 pi
For the medium portrait, diameter = 6
Radius = diameter/2 = 6/2 = 3 in
Area = pi * 3^2 = 9 pi
The difference between the areas of the two sizes of portraits is
81pi - 9pi = 72pi
Since pi = 3.14, then
The difference between the areas of the two sizes of portraits is
72 * 3.14 = 226.08 inches^2
Rounding to the nearest whole number, it becomes
226 inches^2

What is the image of (3,3)(3,3) after a dilation by a scale factor of 1/3
centered at the origin?
The image of (3, 3) after dilation by a scale factor of 1/3 centered at the origin will have coordinate (1, 1)
What is dilation?Dilation refers to the transformation that increases or reduces the image formed after the transformation
When the scale factor is greater that 1 the transformation will lead to magnification when the scale factor is less than 1 the image formed is compressed.
The transformation rule fir dilation is (x, y) → (kx, ky)
where k is the scale factor = 1/3
(3, 3) → (1/3 * 3, 1/3 * 3) → (1, 1)

120°. Find the measure of
If u answer will mark brainlyest and will give 40 points
Answer:
The measure of <CDO and <DCo are 60° and 30°.
Step-by-step explanation:
∠CDO = 1/2 ∠CDA
= 1/2 (120)° = 60°
∠ADC + ∠DCB = 180°
120° + ∠DCB = 180°
⇒ ∠DCB = 180° – 120° = 60°
∠DCO = 1/2 ∠DCB
= 1/2 (60°) = 30°

Please if ur good at pre calc stop to help with the first question please
Answer:
Step-by-step explanation:
The first thing you ought to do is find out what you are trying to get. Desmos is an ideal program to do that if you don't have a graphing calculator. Just search for Desmos. It is pretty obvious once you get there. I've enclosed the graph to show you what it looks like.
Notice what happens around 5. The graph splits because effectively, you are dividing by 0 when you put 5 into the denominator. The question arises why doesn't the same thing happen at 0. It should: There is a discontinuity but it is very tiny. So the domain numbers that you should graph are
-1 0™ 1 2 3 4 4.5 4.8 5.3 5.4 6 7
™I wouldn't make 0 a part of this domain. But you can indicate with a dot where the graph goes.
I haven't filled in the range numbers. That's your job. All you have to do is fill in the table with points. Or you can put them on the graph that I have enclosed just to see where they points belong.
A graph is not to convey accuracy. It is to show the shape of function in question.

The mean bonus paid by large companies to their executives is $5 million and the modal class is 3.5-6.5.
How to calculate the mean and the modal class for the dataTo find the mean, we need to find the midpoint of each class and multiply it by the frequency, then add up all of these values and divide by the total frequency:
Class boundaries Midpoint Frequency Midpoint x Frequency
0.5-3.5 2 11 22
3.5-6.5 5 12 60
6.5-9.5 8 4 32
9.5-12.5 11 2 22
12.5-15.5 14 1 14
Total 150
Mean = (Midpoint x Frequency) / Total Frequency
Mean = 150 / 30
Mean = 5
Therefore, the mean bonus paid by large companies to their executives is $5 million.
To find the modal class, we need to look for the class with the highest frequency. In this case, the class with the highest frequency is 3.5-6.5, with a frequency of 12. Therefore, the modal class is 3.5-6.5.

OU Daily predicts that the OU Sooners will have a better football season than the USC Trojans. Which of the following best represents the OU Daily's null hypothesis?
A. OU Sooners = USC Trojans
B. OU Sooners ≠ USC Trojans
C. OU Sooners > USC Trojans
D. OU Sooners < USC Trojans
The best statement that represents the OU daily's null hypothesis is OU Sooners = USC Trojans
What is statement ?
A declarative sentence that can only be true or false—neither—is referred to as a statement. A proposition may also be used to refer to a statement. There must be no uncertainty; this is crucial. A sentence can only be true or untrue, not both, in order to be considered a statement.
A meaningful group of words can be used to form a mathematical assertion, which can either be true or untrue. They are simply referred to as a statement. For example, the word "p" could stand for the phrase "ABC is an equilateral triangle." In an equilateral triangle, p thus equals ABC.
OU daily - predicts that,

Answer:
∠ DCF = 45°
Step-by-step explanation:
given AB is parallel to CD , then
∠ BAF and ∠ AEC are alternate angles and are congruent , that is
∠ AEC = ∠ BAF = 75°
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ AEC is an exterior angle of Δ CEF , then
∠ DCF + ∠ CFA = ∠ AEC
∠ DCF + 30° = 75° ( subtract 30° from both sides )
∠ DCF = 45°

4. Samantha received $59 for her birthday. She spent $25 on a
charm bracelet. Her brother now has twice as much money as
Samantha. How much money does Samantha's brother have?
The answer will be $68 and Here's Why:
Samantha received $59 for her birthday. That will be the base of the equation. She spent $25 on a charm bracelet so that will be the number being subtracted.
$59 - $25 = $34
We also know that he brother has twice as much money as she does. So that means he has 2x more money than her.
So: $34 x 2 = $68.
So here brother has $68 more than her.
Finde the value of x in the proportion ( 5x+ 1 ):3 =(2x +2): 7(6 x) = (4x) :7
In the proportion (5x + 1):3 = (2x + 2):7, the value of x is -1/29.
In the proportion (6x):(4x) = 7, there is no value of x that satisfies the proportion.
To find the value of x in the given proportions, let's solve them one by one:
(5x + 1) : 3 = (2x + 2) : 7
To solve this proportion, we can cross-multiply:
7(5x + 1) = 3(2x + 2)
35x + 7 = 6x + 6
Subtracting 6x from both sides and subtracting 7 from both sides:
35x - 6x = 6 - 7
29x = -1
Dividing both sides by 29:
x = -1/29
Therefore, the value of x in the first proportion is -1/29.
(6x) : (4x) = 7
To solve this proportion, we can simplify the left side:
6x / 4x = 7
Dividing both sides by 2x:
3/2 = 7
This equation is not true, as 3/2 is not equal to 7.
Therefore, there is no value of x that satisfies the second proportion.
In summary, the value of x in the proportion (5x + 1) : 3 = (2x + 2) : 7 is -1/29, and there is no value of x that satisfies the proportion (6x) : (4x) = 7.

X=0,1,2,3,4,5,6,7,8
Y=6,7,8,9,10,11,12,13,14
What is the slope? What does it represent?
Answer:
\(Slope = 1\)
It represents: The number of tents made in an hour
Step-by-step explanation:
Given
X=0,1,2,3,4,5,6,7,8
Y=6,7,8,9,10,11,12,13,14
Required
Determine the slope
The slope is calculated as:
\(Slope = \frac{y_2 - y_1}{x_2 - x_1}\)
Pick any two corresponding values of x and y
\((x_1,y_1) = (0,6)\)
\((x_1,y_1) = (8,14)\)
\(Slope = \frac{y_2 - y_1}{x_2 - x_1}\)
\(Slope = \frac{14 - 6}{8 - 0}\)
\(Slope = \frac{8}{8}\)
\(Slope = 1\)
It represents: The number of tents made in an hour

There are 16 tablespoons in 1 cup. How many tablespoons of cornstarch would Cheryl need to make the green slime recipe 15 times?
Cheryl would need 240 tablespoons of cornstarch to make the green slime recipe 15 times.
What is multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.
To make the green slime recipe 15 times, Cheryl would need 15 times the amount of cornstarch listed in the recipe.
If 1 cup of cornstarch is needed for one recipe, then 15 cups of cornstarch would be needed to make the recipe 15 times.
Since there are 16 tablespoons in 1 cup, the number of tablespoons of cornstarch needed to make the recipe 15 times is:
= 16 tablespoons/cup x 15 cups
= 240 tablespoons.
So, Cheryl would need 240 tablespoons of cornstarch to make the green slime recipe 15 times.

Step-by-step explanation:
y = x^2 - 12x - 5
steps to complete the square
add a 5 to both sides to move the constant
x^2 - 12x = 5
Then take -12, the coefficient of the variable and divide by 2 and square.
12/2 = 6, 6^2 = 36
Then add 36 to both sides.
x^2 - 12x + 36 = 5 + 36
Then subtract the 5 and 36 from both sides.
x^2 - 12x + 36 - 36 - 5
