The measurement of the distance from the tip of the slice of pizza to the crust is the radius.
The diameter of the pizza is 12 inches and the circumference is 37.7 inches
How to find the circumference?A slice of pizza is cut from the middle of the pizza to the crust. It is therefore cut from the middle of the pizza (circle) to the edge of the pizza (circle).
This is the radius because the radius is the straight - line distance from the edge of the middle of a circle to the edge.
If the radius is 6 inches, the diameter is:
= radius x 2
= 6 x 2
= 12 inches
The circumference is:
= π x diameter
= 22/7 x 12
= 37.7 inches

Write the domain and the range of the function as an inequality, using set notations, and using interval notation. Also describe the end behavior of the function or explain why there is no end behavior (19 points and brainliest)
Answer:
Step-by-step explanation:
I think we need to define domain and range first.
Domain is the set of all x values where the function f(x) exists or is defined.
Range is the set of all y values that will result from substituting all x values (the domain) into the function.
So for g(x) = 2x - 2 we can evaluate g(x) at any point, and we will get a real answer for y.
So the range of g(x) = 2x -2 is also all real numbers, because no matter what value of x is, we can always multiply that number by 2 and subtract 2.
The inequality does not affect the domain and range of linear functions at all. Don't confuse domain and range with a solution to an inequality. These two concepts are different. Domain and range mean all possible values of x and y that could be substituted into the inequality. A solution means all possible values that make the inequality statement true.
The domain as an inequality would be -∞ < x < ∞
The range as an inequality would be -∞ < y < ∞
As a set notation:
Domain {x | -∞ < x < ∞}
Range {y | -∞ < x < ∞}
In interval notation:
Domain (-∞ , ∞)
Range (-∞ , ∞)
End behavior:
As x gets larger and larger, g(x) gets larger and larger as well, and as x gets smaller, g(x) gets smaller too.

List the first six terms of the sequence defined by an = (5n -1 )/3n+1 Q1 = a1= , a2= , a3=,
a4= , a5= ,a6=
Does the sequence appear to have a limit? (enter Yes or No) If so, find it.
The first six terms of the sequence defined by an = (5n -1 )/3n+1 Q1 = a1= 1, a2=1.286 , a3=1.4, a4=1.462 , a5=1.5 ,a6=1.526 . Therefore, the sequence has a limit of 5/3.
To find the first six terms of the sequence defined by an = (5n -1 )/3n+1, we need to substitute the values of n=1, 2, 3, 4, 5, and 6 into the expression given.
Then we will have the values of the first six terms of the sequence:
a1 = (5(1) - 1)/(3(1) + 1) = 4/4 = 1
a2 = (5(2) - 1)/(3(2) + 1) = 9/7 ≈ 1.286
a3 = (5(3) - 1)/(3(3) + 1) = 14/10 = 1.4
a4 = (5(4) - 1)/(3(4) + 1) = 19/13 ≈ 1.462
a5 = (5(5) - 1)/(3(5) + 1) = 24/16 = 1.5
a6 = (5(6) - 1)/(3(6) + 1) = 29/19 ≈ 1.526
To find whether the sequence appears to have a limit or not, we can observe the values of the sequence. As we can see, the values of the sequence are increasing, but they do not seem to be increasing without bound.
Therefore, the sequence appears to have a limit. Using the limit formula, we can find the limit of the sequence as follows: lim n→∞ (5n - 1)/(3n + 1) = lim n→∞ [(5/n) - (1/n)] / [(3/n) + (1/n)] = lim n→∞ [5 - 1/n] / [3 + 1/n] = 5/3
So, the sequence has a limit of 5/3.

A hashing algorithm is a routine that converts a primary key value into a relative record number. T/F
True. A hashing algorithm is a mathematical routine used to generate a hash value from a primary key value.
A relative record number that may be used to retrieve the required record in a data structure is created using this hash value.
In order to facilitate quick access to the data, the hashing algorithm makes sure that the same hash value is generated for every primary key. How quickly the requested record can be found depends on how effective the hashing method is.
Also, it must be safe enough to prevent two main key values from producing the same hash value, as doing so might result in accessing the wrong records.

The length of side b is 56m, angle A is 45°, and angle C is 67°.
What is the length of side b in the given triangle?In the given triangle with side lengths a = 74m, b ≈ 56m, and c = 36m, the length of side b is approximately 56m.
To solve the triangle, we can use the Law of Cosines and the fact that the sum of angles in a triangle is 180 degrees. Given angle B = 67°51', we have:
Length of side b:Using the Law of Cosines, we have:
b² = a² + c² - 2ac * cos(B)
Substituting the known values:
b² = 74² + 36² - 2 * 74 * 36 * cos(67°51')
Calculating the value of b:
b ≈ √(74² + 36² - 2 * 74 * 36 * cos(67°51'))
b ≈ 55.92m (rounded to the nearest whole number, b ≈ 56m)
Measure of angle A:Using the Law of Cosines again, we have:
cos(A) = (b² + c² - a²) / (2 * b * c)
Substituting the known values:
cos(A) = (56² + 36² - 74²) / (2 * 56 * 36)
Calculating the value of A:
A = cos⁻¹((56² + 36² - 74²) / (2 * 56 * 36))
A ≈ 45° (rounded to the nearest whole number)
Measure of angle C:Using the fact that the sum of angles in a triangle is 180 degrees:
C = 180° - A - B
Substituting the known values:
C ≈ 180° - 45° - 67°51'
Calculating the value of C:
C ≈ 67°9' (rounded to the nearest whole number, C ≈ 67°)
Therefore, in the given triangle, the length of side b is approximately 56m, angle A is approximately 45°, and angle C is approximately 67°.

Solve linear equation by substitution. check solution
y = -2x + 4
-x + 3y = -9
The required solution (x, y) = (3, -2) satisfies both equations, and it is the correct solution.
To solve the linear equation -x + 3y = -9 by substitution using the equation y = -2x + 4, we can substitute y in the second equation with -2x + 4 from the first equation, as follows:
-x + 3(-2x + 4) = -9
x - 6x + 12 = -9
-7x = -21
x = 3
Now, we can use the value of x to find the value of y from the first equation,
y = -2x + 4:
y = -2(3) + 4
y = -2
So the solution to the system of equations is (x, y) = (3, -2).
To check the solution, we can substitute the values of x and y in both equations and verify that they are true:
y = -2x + 4 becomes -2 = -2(3) + 4, which is true.
-x + 3y = -9 becomes -3 + 3(-2) = -9, which is also true.

Hence option D is correct.
Here the right angle triangle is mentioned,
We know that,
A right-angled triangle is one with one of its internal angles equal to 90 degrees, or any angle is a right angle.
As a result, this triangle is also known as the right triangle or the 90-degree triangle.
We know that the Pythagoras theorem for a right angled triangle:
(Hypotenuse)²= (Perpendicular)² + (Base)²
So, the set of numbers that does not necessarily represent side lengths of a right triangle is a+5, b+5, c+5.
Because adding 5 to each side won't necessarily satisfy the Pythagorean theorem.
Hence,
The given set a+5, b+5, c+5 will not form a right angle triangle.

The expression that represent the area of the cabin for rectangular floor plan is 2w² + 5w.
What is the area of rectangular shape?
In essence, the area of a rectangle is equal to the sum of its length and breadth. In contrast, the circumference of a rectangle is equal to the product of its four sides. Consequently, we can say that the area of a rectangle equals the space enclosed by its perimeter.
Given that the length of a cabin is equal to 5 feet more than twice the width.
Assume that the width of the cabin be w.
Then the mathematical expression of twice the width is 2w.
Then the mathematical expression of 5 feet more than twice the width is 2w + 5.The length of the cabin is 2w + 5 feet.
The area of rectangular shape is product of length and width.
The area of the cabin is (2w + 5)w

what is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations? (round your answer to three decimal places.)
0.003 is the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations
To calculate the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations.The mean is the expected number of calls involving a fax transmission, while the standard deviation is the measure of variability in the distribution. We then use this information to calculate the probability of exceeding the expected number by more than 2 standard deviations, which can be done using the z-score formula. The z-score for values more than 2 standard deviations away from the mean is 2.33, which corresponds to a probability of 0.003. Thus, the probability that the number of calls among the 25 that involve a fax transmission exceeds the expected number by more than 2 standard deviations is 0.003.

There is a stack of 10 cards, each given a different number from 1 to 10. Suppose we select a card randomly from the stack, replace it, and then randomly select another card. What is the probability that the first card is an odd number and the second card is less than 4? Write your answer as a fraction in the simplest form
Answer:
There are 10 cards in the stack, and 5 of them are odd (1, 3, 5, 7, and 9). There are 3 cards (1, 2, and 3) that are less than 4. Since we are replacing the first card before selecting the second, the outcomes are independent and we can multiply the probabilities of each event.
The probability of selecting an odd card on the first draw is 5/10, or 1/2.
The probability of selecting a card less than 4 on the second draw is 3/10, since there are 3 cards that meet this condition out of a total of 10.
Therefore, the probability of selecting an odd card on the first draw and a card less than 4 on the second draw is:
(1/2) x (3/10) = 3/20
So the probability of selecting an odd card on the first draw and a card less than 4 on the second draw is 3/20.
Step-by-step explanation:
Answer:
3/20.
Step-by-step explanation:
To find the probability of two independent events happening together, we multiply their individual probabilities. The probability of the first card being an odd number is 5/10, because there are 5 odd numbers out of 10 cards. The probability of the second card being less than 4 is 3/10, because there are 3 cards (1, 2, and 3) that are less than 4 out of 10 cards. Therefore, the probability of the first card being an odd number and the second card being less than 4 is:
5/10 x 3/10 = 15/100
We can simplify this fraction by dividing both the numerator and denominator by 5:
15/100 = 3/20
So, the final answer is 3/20.

Where's the picture?
Step-by-step explanation:
an airplane flying at an elevation of 3,500 ft., directly above a straight highway. two motorists are driving cars on the highway on opposite sides of the plane. the angle of depression to one car is 31 degrees and to the other is 53 degrees. how far apart are the cars?
The first and second cars are 7724 feet apart from each other.
The angle of depression is the angle we have to move your eyes downwards to look at the car from the plane. Let's start with the first car, with the 31° angle of depression. Draw an upside-down right triangle with vertices at the plane, the car, and the point 3500 feet in the air above the car (level with the plane). The vertex at the plane is 31° and the right angle is the vertex in the air above the car. The length of the leg from the car to the point in the air above the car is 3500 feet. We like to find the length of the leg from the plane to the point in the air above the car. Since the two sides involved are the legs of the triangle, use tangent:
tan = opposite/ adjacent
⇒ tan(31°) = 3500/x
⇒ 0.60086 = 3500/x
⇒ 0.67 x = 3500 [ rounding up 0.60086 = 0.67]
⇒ x = 5223.88
That means the first car is 5223.88 feet from the point on the highway below the plane.
We can do something similar with the second car, which has an angle of depression of 53° from the plane. Again, the leg from the car to the point in the air above the car (level with the plane) is 3500 feet, the right angle is at the vertex at the point in the air above the car, and the 53° angle is at the vertex at the plane. We are looking for the length of the other leg, which runs from the plane to the point in the air above the car. Use tangent:
tan(53°) = 3500/x
⇒ 1.327 = 3500/x
⇒ 1.4x = 3500 [ rounding 1.327 = 1.4]
⇒ x = 3500/1.4
⇒ x = 2500
That means the second car is 2500 feet from the point on the highway below the plane.
Add the two distances together to get the total distance from car to car:
5223.88 + 2500.00 = 7723.88
So, rounded to the nearest foot, the cars are 7724 feet apart.
