To find the measure of each interior and exterior angle of a regular 30-gon, we can use the formula:
Interior angle = (n - 2) * 180° / nExterior angle = 360° / nIn this case, we have a regular 30-gon, so n = 30.
Let's calculate the measures:
Interior angle = (30 - 2) * 180° / 30 = 28 * 180° / 30 = 168°Exterior angle = 360° / 30 = 12°Therefore, each interior angle of the regular 30-gon measures 168°, and each exterior angle measures 12°.

The equation of the parabola with the given focus (2, 7) and directrix y = -1 is [tex](x - 2)^2 = 12(y - 3)^2[/tex].Option C.
To find the equation of the parabola with a focus and directrix, we can use the standard form of the equation of a parabola:
For a vertical parabola:
[tex](x - h)^2 = 4p(y - k),[/tex]
where (h, k) is the vertex, and p is the distance from the vertex to the focus and directrix.
In this case, the focus is given as (2, 7), which means the vertex is also (2, 7) since the focus and vertex lie on the axis of symmetry. Additionally, the directrix is given as y = -1, which means the directrix is a horizontal line.
First, let's determine the distance from the vertex to the focus and directrix, which is the value of p. The distance is the absolute difference between the y-coordinate of the focus (7) and the y-coordinate of the directrix (-1):
p = |7 - (-1)| = 8.
Now we can substitute the values of the vertex (h, k) = (2, 7) and p = 8 into the standard form equation:
[tex](x - 2)^2 = 4(8)(y - 7).[/tex]
Simplifying further:
[tex](x - 2)^2 = 32(y - 7).[/tex]
Expanding the equation:
[tex]x^2 - 4x + 4 = 32y - 224.[/tex]
Rearranging the terms:
[tex]x^2 - 4x - 32y + 228 = 0.[/tex]
Therefore, the equation of the parabola with the given focus (2, 7) and directrix y = -1 is [tex](x - 2)^2 = 12(y - 3)^2.[/tex] SO Option C is correct.

Jonah's swimming pool is 21 meters by 20 meters. He swam from one corner of the pool to the opposite corner. How far did Jonah swim?
Jonah swam a distance of 29 meters from one corner of the pool to the opposite corner.
To determine how far Jonah swam from one corner of the pool to the opposite corner, we can use the Pythagorean theorem. According to the theorem, in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.
In this case, the two sides of the right-angled triangle are the length and width of the swimming pool, which are 21 meters and 20 meters respectively. The distance Jonah swam represents the hypotenuse of the triangle.
Using the Pythagorean theorem:
[tex]Hypotenuse^2 = Length^2 + Width^2[/tex]
[tex]Hypotenuse^2[/tex] =[tex]21^2 + 20^2[/tex]
[tex]Hypotenuse^2[/tex]= 441 + 400
[tex]Hypotenuse^2[/tex]= 841
Taking the square root of both sides, we find:
Hypotenuse =[tex]\sqrt{841[/tex]
Hypotenuse = 29

Are these probabilities equal? If so, explain your reasoning. If not, explain which one is the greatest and why.
P(B) when you have no other information.
P(B) when you know A is true.
P(B) when you know A is false.
The probability of event B would likely be greater when event A is true, reflecting the tendency of professional basketball players to be taller.
To determine the probabilities in question, we need to consider the information provided and make some assumptions based on general knowledge about the population of the United States.
P(B) when you have no other information:
Without any other information, we cannot accurately determine the probability of event B, which represents "The woman is taller than 5 feet 4 inches." We would need additional data on the height distribution of women in the United States to calculate this probability.
P(B) when you know A is true:
If we know that event A is true, meaning "The woman is a professional basketball player," we can make some assumptions based on the nature of professional basketball players.
Generally, professional basketball players tend to be taller than the average population due to the physical requirements of the sport. Therefore, the probability of event B, "The woman is taller than 5 feet 4 inches," would likely be greater when we know event A is true.
P(B) when you know A is false:
If event A is false, meaning "The woman is not a professional basketball player," we cannot make any definitive conclusions about the probability of event B, "The woman is taller than 5 feet 4 inches." The height of an individual is not solely determined by their profession, so without further information, we cannot determine if event B is more or less likely when event A is false.
In summary, based on the given information, we can conclude that the probabilities of event B are not equal under different scenarios. The probability of event B would likely be greater when event A is true, reflecting the tendency of professional basketball players to be taller. However, without any other information, we cannot determine the probability of event B or make comparisons when event A is false.

two rectangles have the same base lengths. one rectangle has a height that is twice the height of the other rectangle. are the heights and areas proportional
Although the rectangles have the same base lengths, the heights and areas are not directly proportional in this case.
Are the heights and areas of the rectangles proportional?Let's denote the base length of both rectangles as 'b'. If one rectangle has a height that is twice the height of the other rectangle, we can denote the heights as 'h' and '2h', respectively.
The area of a rectangle is calculated by multiplying the base length by the height. Therefore, the area of the first rectangle with height 'h' would be A₁ = b * h, and the area of the second rectangle with height '2h' would be A₂ = b * (2h) = 2b * h.
Comparing the two areas, we have A₁ = b * h and A₂ = 2b * h. It is evident that the areas are not proportional because the area of the second rectangle is twice the area of the first rectangle.

$h\ \approx$
in.
The nearest Whole number, the missing dimension (height) of the cylinder is approximately 39 inches.
The missing dimension of the cylinder, we can use the formula for the volume of a cylinder:
Volume = π * r^2 * h
Given that the volume is 10,000π in³ and the diameter of the base is 32 inches, we can determine the radius (r) of the cylinder.
The diameter is twice the radius, so the radius is half of the diameter:
r = 32 inches / 2 = 16 inches
Substituting the known values into the volume formula, we have:
10,000π in³ = π * (16 in)^2 * h
Cancelling out the common factor of π, we get:
10,000 = 16^2 * h
Simplifying further:
10,000 = 256 * h
To isolate h, we divide both sides of the equation by 256:
h = 10,000 / 256
Calculating the value of h:

b. $1,445,000
d. $361,250
The maximum revenue, to the nearest whole dollar, is $180,625 (option c).
To find the maximum revenue, we need to determine the vertex of the quadratic function represented by the revenue equation.
The revenue equation is given as:
R(p) = -4p² + 1700p
The vertex of a quadratic function in the form of f(x) = ax² + bx + c can be found using the formula:
x = -b / (2a)
For the given revenue equation, a = -4 and b = 1700. Plugging these values into the formula, we have:
p = -1700 / (2 × -4)
p = -1700 / -8
p = 212.5
The maximum revenue occurs at p = 212.5.
To find the maximum revenue, we substitute this value back into the revenue equation:
R(p) = -4(212.5)² + 1700(212.5)
R(p) = -4(45256.25) + 361250
R(p) = -181025 + 361250

You empty a 2-liter bottle every 8 seconds into tanks that hold 50 gallons. How long will it take you to fill 11 tanks? (3.8 l = 1 gallon)(Convert 11 tanks to hours)
It will take approximately 2.32 hours to fill 11 tanks.
First, we need to convert the capacity of the tanks from gallons to liters, as the rate at which we empty the bottle is given in liters. Since 1 gallon is equal to 3.8 liters, the capacity of each tank is 50 gallons * 3.8 liters/gallon = 190 liters.
Now, let's calculate the time it takes to fill one tank:
The bottle is emptied at a rate of 2 liters every 8 seconds. To find the time it takes to fill one tank, we divide the capacity of the tank (190 liters) by the rate at which we empty the bottle (2 liters/8 seconds):
Time for one tank = 190 liters / (2 liters/8 seconds) = 190 liters * (8 seconds/2 liters) = 760 seconds.
Next, we need to find the total time required to fill 11 tanks. Since each tank takes 760 seconds to fill, we multiply this by 11 to account for the 11 tanks:
Total time to fill 11 tanks = 760 seconds/tank * 11 tanks = 8,360 seconds.
Finally, we convert the total time from seconds to hours. There are 60 seconds in a minute and 60 minutes in an hour, so:
Total time to fill 11 tanks = 8,360 seconds * (1 minute/60 seconds) * (1 hour/60 minutes) = 2.32 hours (rounded to two decimal places).
Therefore, it will take approximately 2.32 hours to fill 11 tanks.

Solve (D ^ 2 - 6D + 9) * y = 0
The solution to the given differential equation is y(x) = (C1 + C2x) * e^(3x), where C1 and C2 are arbitrary constants.
To solve the given differential equation, we need to find the function y(x) that satisfies the equation:
(D^2 - 6D + 9)y(x) = 0,
where D represents the differentiation operator.
Let's break down the solution process step by step:
Characteristic Equation
First, we'll find the characteristic equation associated with the given differential equation. For a second-order linear homogeneous differential equation of the form aD^2y + bDy + cy = 0, the characteristic equation is obtained by replacing D with λ:
λ^2 - 6λ + 9 = 0.
Solving the Characteristic Equation
Now, we solve the characteristic equation to find the values of λ. Factoring the equation, we get:
(λ - 3)^2 = 0.
From this, we see that λ = 3 (with a multiplicity of 2).
General Solution
The general solution of the differential equation is given by:
y(x) = C1e^(λ1x) + C2xe^(λ2*x),
where C1 and C2 are arbitrary constants, and λ1, λ2 are the distinct roots of the characteristic equation.
In our case, since we have repeated roots, the general solution simplifies to:
y(x) = C1e^(3x) + C2xe^(3*x).

What is the value of x? Round to the nearest thousandth.
Applying the tangent ratio, the value of x in the image, rounded to the nearest thousandth is: 15.824.
How to Find the Value of x Using the Tangent Ratio?The tangent ratio, commonly referred to as "tangent," is a trigonometric function that relates the ratio of the length of the side opposite an angle to the length of the side adjacent to that angle in a right triangle. It is expressed as:
tan (∅) = opposite/adjacent
We have the following:
Reference angle (∅) = 53 degrees
Length of opposite side = 21
Length of adjacent side = x
Plug in the values:
tan 53 = 21/x
x * tan 53 = 21
x = 21 / tan 53
x = 15.824

A jogger running around a rectangular park takes a shortcut back to his car by running 53 meters from one corner to the opposite corner. If the park is 45 meters long, what is the width?
Answer:
28 meters Aprox
Step-by-step explanation:
To find the width of the rectangular park, we can use the Pythagorean theorem. The diagonal running from one corner to the opposite corner forms a right triangle with the length and width of the park.
Given:
Length of the park (L) = 45 meters
Diagonal distance (d) = 53 meters
Using the Pythagorean theorem:
d² = L² + W²
(53 meters)² = (45 meters)² + W²
2809 = 2025 + W²
W² = 2809 - 2025
W² = 784
Taking the square root of both sides:
W ≈ √784
W ≈ 28
Therefore, the width of the rectangular park is approximately 28 meters.
which of the following is the slope of the line with equation -7x=6+3y
Answer:
Slope = -7/3
Step-by-step explanation:
-7x = 6 + 3y is in the standard form of a line, whose general equation is
Ax = C + By (it's sometimes written in terms of C and is Ax + By = C, but in this problem, it's written in terms of Ax).
We can find the slope of the line by converting from standard form to slope-intercept form, whose general equation is y = mx + b, where
m is the slope,and b is the y-intercept.Step 1: Subtract 6 from both sides:
(-7x = 6 + 3y) - 6
-7x - 6 = 3y
Step 2: Divide both sides by 3 to isolate y:
(-7x - 6 = 3y) / 3
-7/3x - 2 = y
Thus, the slope of the line is -7/3
Answer: Therefore the slope is [tex]-\frac{7}{3}[/tex].
Step-by-step explanation:
We can rewrite the equation -7x=6+3y in slope-intercept form y = mx + b, where the m is the slope of the line, and b is the y-intercept.
-7x = 6 + 3y
-6 -6
-7x - 6 = 3y
[tex]\frac{-7x}{3}-\frac{6}{3} =\frac{3y}{3}[/tex]
[tex]\frac{-7}{3}x-2 =y[/tex]
Therefore the slope is [tex]-\frac{7}{3}[/tex].
