100 Points! Algebra question. Photo attached. Find the amplitude, if it exists, and period of the function. Then graph the function. Thank you!
hello
the answer to the question is:
y = a cot(bx – c) + d
a = 1, b = 1/2, c = 0
the midline is y = d, so y = 0
the vertical stretch is 1, so label the y-axis so the inflection point of the curve is 1 above the midline, and the other inflection point is 1 below the midline
the period is:
T = π/b ----> T = 2π
the phase shift is:
PS = c/b ----> PS = 0
and also, there's no amplitude for tangent and cotangent, there is only the vertical stretch that takes the place of an amplitude
Answer:
amplitude does not exist. period = 2π (360°)
Step-by-step explanation:
there is no amplitude for tan θ or cot θ, since there is no limit up or down (positive/negative infinity).

s. The area of a regular hexagon is 384√3Cm². Find A. the side length of the hexagon B. the radius of the hexagon C. the apothem of the hexagon
The apothem of the hexagon is 8√3 cm.
We are given that;
The area of a regular hexagon= 384√3Cm²
Now,
To find the side length, radius, and apothem of a regular hexagon given its area, we can use the following formulas:
Area = (3√3 s^2) / 2 Area = (1/2) a P Area = (3/2) r a
where s is the side length, a is the apothem, P is the perimeter, and r is the radius of the hexagon. We can solve for any of these variables by rearranging the formulas and plugging in the given area.
A. To find the side length, we can use the first formula and solve for s:
s^2 = (2 Area) / (3√3) s = sqrt((2 Area) / (3√3))
Plugging in Area = 384√3, we get:
s = sqrt((2 * 384√3) / (3√3)) s = sqrt(256) s = 16
Therefore, the side length of the hexagon is 16 cm.
B. To find the radius, we can use any of the formulas and solve for r. For example, using the third formula, we get:
r = (2 Area) / (3 a)
To find a, we can use the second formula and solve for a:
a = (2 Area) / P
To find P, we can use the fact that P = 6s and plug in s = 16:
P = 6 * 16 P = 96
Plugging in P and Area into the formula for a, we get:
a = (2 * 384√3) / 96 a = 8√3
Plugging in a and Area into the formula for r, we get:
r = (2 * 384√3) / (3 * 8√3) r = 32
Therefore, the radius of the hexagon is 32 cm.
C. To find the apothem, we can use any of the formulas and solve for a. For example, using the second formula, we get;
a = (2 Area) / P
Plugging in Area = 384√3 and P = 96, we get:
a = (2 * 384√3) / 96 a = 8√3
Therefore, by polygon the answer will be 8√3 cm.

The proportion of all US adults who eat popcorn when they go to the movie theater is p = 0.87. A random sample of 20 US adults was selected and asked if they eat popcorn when they go to the movie theater. Which of the following is the shape of the sampling distribution of p hat ?
a. The sampling distribution of p hat is approximately Normal because n p = 17.4 greater-than 10.
b. Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10, the sampling distribution of p hat is not approximately Normal. The sampling distribution of p hat is skewed right and centered at 0.87.
c. Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10 , the sampling distribution of p hat is not approximately Normal. Because p = 0.87 is closer to 1 than 0, the sampling distribution of p hat is skewed to the left.
d. Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10, the sampling distribution of p hat is not approximately Normal. Because p = 0.87 is closer to 1 than 0, the sampling distribution of p hat is skewed to the right.
The option that represents shapes of the sampling distribution of p hat is:
c. Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10 , the sampling distribution of p hat is not approximately Normal. Because p = 0.87 is closer to 1 than 0, the sampling distribution of p hat is skewed to the left.
What is the shape of the sampling distribution?Normal distribution is defined as the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
Because the requirement for normal is greater than 10, n×p is greater than 10 and nx(1-p) is also greater than 10.
This situation is abnormal because it is not valid. If p is close to 1 in a normal graph, then p is left skewed.
Thus, the option third is correct because nx(1-p)=2.6 less than equal to 10 then the sampling distribution is not approximate normal because p=0.87 is closer to 1 than zero. Sampling distribution is skewed to the left.

What is the slope of the line shown? On a coordinate plane, a line passes through points (negative 6, 7), (negative 2, 6), (2, 5), and (6, 4). The slope is .
Answer:
To find the slope of a line passing through four points, we can use the formula:
slope = (change in y) / (change in x)
We can use any two points to calculate the slope, but since we need to find the slope for the entire line passing through all four points, we need to make sure that the slope is the same for any two points that we choose.
Let's use the points (-6,7) and (-2,6) to calculate the slope:
slope = (6 - 7) / (-2 - (-6)) = -1/4
Now let's use the points (2,5) and (6,4) to calculate the slope:
slope = (4 - 5) / (6 - 2) = -1/4
Since the slope is the same for both pairs of points, we can conclude that the slope of the line passing through all four points is -1/4.

if i have two assignment that's 5% of my grade and i have a 79 in the class what will my grade be if i get a 100 on both???
If you get a perfect score of 100% on both assignments, your overall grade in the class would be 100%.
To calculate your grade, we need to consider the weight of each assignment.
Since each assignment is worth 5% of your grade, we can calculate the contribution of the assignments to your overall grade.
The total weight of the two assignments is 2×5% = 10%.
To find the impact of the assignments on your grade, we multiply your average score on the assignments (100%) by their weight (10%):
Contribution from the assignments = 100% * 10% = 10%
Since you currently have a grade of 79, the remaining 90% of your grade is based on other assessments, tests, or assignments.
To calculate your overall grade, we add the contribution from the assignments to the remaining 90%:
Overall grade = 90% + 10% = 100%
Therefore, if you get a perfect score of 100% on both assignments, your overall grade in the class would be 100%.

In ΔNOP, n = 56 inches, p = 61 inches and ∠P=80°. Find all possible values of ∠N, to the nearest degree.
The value of ∠N is 54.38 degrees.
Given that in ΔNOP, n = 56 inches, p = 61 inches and ∠P=80°.
We need to find the value of ∠N,
According to the cosine rule, the following equation is true for every triangle with sides a, b, and c and the corresponding opposite angles A, B, and C:
c² = 2ab cos(C) - a² + b²
In this instance, we have:
A = P and B = P
C = ∠P
When we enter the values, we obtain:
n² = p² + p² - 2p² cos(∠P)
Substituting the known values:
56² = 61² + 61² - 2(61²) cos(80°)
Simplifying:
3136 = 3721 + 3721 - 2(3721) cos(80°)
3136 = 3721 + 3721 - 7442 cos(80°)
Now we can solve for cos(80°):
3136 = 7442 - 7442 cos(80°)
7442 cos(80°) = 7442 - 3136
cos(80°) = (7442 - 3136) / 7442
cos(80°) ≈ 0.5798
∠N = arccos(0.5798)
∠N = 54.38 degrees.
Hence the value of ∠N is 54.38 degrees.

A box has the shape of a rectangular prism with height 28 cm. If the height is increased by 0.2cm, by how much does the surface area of the box increase? L=13 W=8.7 H=28
The surface area of the box increases by 27.4 cm² when the height is increased by 0.2 cm.
To find the increase in surface area, we first need to calculate the initial surface area of the box and then calculate the surface area after increasing the height.
The formula for the surface area of a rectangular prism is given by:
Surface Area = 2*(length width + length height + width*height)
Initial Surface Area:
Length (L) = 13 cm
Width (W) = 8.7 cm
Height (H) = 28 cm
Initial Surface Area = 2*(138.7 + 1328 + 8.7*28)
Next, we calculate the new surface area after increasing the height by 0.2 cm. The new height is:
New Height = Initial Height + Increase in Height = 28 cm + 0.2 cm
New Surface Area = 2*(138.7 + 13(28+0.2) + 8.7*(28+0.2))
To find the increase in surface area, we subtract the initial surface area from the new surface area:
Increase in Surface Area = New Surface Area - Initial Surface Area
Let's calculate the values:
Initial Surface Area = 2*(138.7 + 1328 + 8.728) = 2(113.1 + 364 + 243.6) = 2*(720.7) = 1441.4 cm²
New Surface Area = 2*(138.7 + 13(28+0.2) + 8.7*(28+0.2)) = 2*(113.1 + 377.2 + 244.1) = 2*(734.4) = 1468.8 cm²
Increase in Surface Area = New Surface Area - Initial Surface Area = 1468.8 cm² - 1441.4 cm² = 27.4 cm²
Therefore, the surface area of the box increases by 27.4 cm² when the height is increased by 0.2 cm.

The solution is
The missing number in the original division problem is 28.
The solution is 113 ÷ 4 = 28.
The given division problem is: 113 ÷ 4 = 2 18.
To find the missing number, we can perform the division calculation step by step.
First, we divide 4 into the first digit of 113, which is 1.
Since 4 cannot be divided evenly into 1, we bring down the next digit, which is 1.
Now we have 11.
Next, we divide 4 into 11.
We can divide 4 into 11 two times, which gives us 8.
We subtract 8 from 11, leaving us with a remainder of 3.
Now, we bring down the next digit, which is 3.
We have 33.
Finally, we divide 4 into 33. 4 can be divided into 33 eight times, which gives us 32.
We subtract 32 from 33, leaving us with a remainder of 1.
So, the complete division is 113 ÷ 4 = 28 remainder 1.

You will create an estimate in order to assist your boss in gaining the job!
The equation that is given by the customer for the pool is (units are in feet): x2 + y2 = 81
- Your performance needs to include the following calculations:
- Compute the radius and diameter of the pool.
- Compute the volume of water in the pool using the above calculations and a height of 4 ft.
- Assuming that water costs $0.22 per gallon and that pools cost $185 per foot of radius calculate the total cost of materials for the pool. Keep in mind that there are 7.48 gallons of water per square foot.
- Assuming that a pool will take 2.5 hrs. per foot of radius, compute the total labor hours for the pool.
- If you are to pay someone $19/hr, compute the total cost of labor.
- Find a total cost for the project.
- All of the above is done showing all work.
- A final paragraph that describes your steps and findings.
The solution has been explained below.
We will use the following equation, x² + y² = 81, where x and y are the pool's dimensions in feet, to determine the necessary estimations for the pool project.
1. Calculate the pool's diameter and radius:
We can infer that the radius of the pool is equal to the square root of 81 because the equation depicts a circle. As a result, r = 81 = 9 ft.
The pool's diameter is simply equal to twice its radius, or d = 2r = 18 feet.
2. Calculate the amount of water in the pool:
Since the pool is 4 feet high, we can determine its volume by multiplying the area of its circle-shaped base by the height.
The formula A = πr² can be used to calculate the area of the pool's base,
Therefore, V = Ah = πr²h = 1017.87 cubic feet represents the volume of water in the pool.
3. Determine the pool's total material cost:
There are 7.48 gallons in a cubic foot and a gallon of water costs $0.22.
As a result, Cw = V × 7.48 × 0.22 = 1017.87 × 7.48 × 0.22 = $1,619.72 is the entire cost of water for the pool.
If the radius of the pool is $185 per foot, then the cost of the materials is Cm = r × 185 = 9 × 185 = $1,665.
4. Calculate the pool's total labour hours:
A pool's construction is estimated to take 2.5 hours for every foot of its radius.
So, L = r × 2.5 = 9 × 2.5 = 22.5 hours of labour would be needed to complete this pool.
5. Calculate the total cost of labour for the project:
If you pay someone $19 per hour, Cl = L × 19 = 22.5 × 19 = $427.5.
6. Find the project's overall cost:
The project's overall cost is the product of its labour and material costs:
Cost as a whole equals Cm + Cw + Cl, which is 1,665 + 1,619.72 + 427.5, or $3,712.22.
In conclusion, the pool has an 18-foot diameter and a 9-foot radius according to the supplied equation. There are roughly 1017.87 cubic feet of water in the pool. Water and building supplies are included in the pool's projected material cost of $3,284.72. 22.5 hours of labour in total are needed, with a labour cost estimate of $427.5. Consequently, $3,712.22 is the expected final cost of the pool renovation.

The value of the expression 28 - {15 (3+2)} is -47.
To evaluate the expression 28 - {15 (3+2)}, we need to follow the order of operations (also known as PEMDAS/BODMAS) which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
Let's break down the expression step by step:
First, we solve the expression inside the parentheses:
3 + 2 = 5
Now, we substitute the result back into the original expression:
28 - {15 * 5}
Next, we perform the multiplication:
15 * 5 = 75
Now, we substitute the result back into the expression:
28 - 75
Finally, we perform the subtraction:
28 - 75 = -47
Therefore, the value of the expression 28 - {15 (3+2)} is -47.

Does the relation represent a function: C. Yes, because for each input there is exactly one output.
What is a function?In Mathematics and Geometry, a function can be defined as any mathematical equation which is typically used to define and represent a relationship that exists between two or more variables such as an ordered pair, points on a graph or table.
Based on the mapping diagram, we can reasonably infer and logically deduce that the relation represent a function because the input values (domain, x-value, or independent values) are uniquely mapped to the output values (range, y-value or dependent values).
In this context, we can reasonably infer and logically deduce that the relation represent a function because for each input (independent value) there is exactly one output (dependent variable).

Given the net, what is the surface area of the rectangular prism below?
PLS HELP WILL MARK BRAINLIST
Answer:
40
Step-by-step explanation:
For finding the surface area of this rectancular prism, or any, we find the area of each shape. Then, we add up all of the areas together to get the surface area. There are 2 squares with 2 as a side length for each side. To find the area of a square, we can multiply any 2 sides. That is because the sides of the square is equal to eachother, so 2•2=4. Being 2 squares, they are both have area of 4. Looking at the 4 rectangles, they have a length of 4 and a width of 2. We multiply the height and width of a rectangle to get the area. 4•2=8, the area of each rectangle is 8. Now, we add up all of our areas. Two squares, each are 4 for their area. Add them up, you get 8 for the 2 squares. Then, we have 4 rectangles each are 8 for their area. 4•8=32 since they all have the same area. 32+8=40! 40 is the surface area of this net. I hope this helps, and have good day

f(x)=3x^2+2x+4
Answer: 10
Step-by-step explanation:
Solve x2 + 6x − 8 = 0 by completing the square. (1 point)
(x + 3)2 = 17; x equals negative 3 plus or minus the square root of 17
(x + 3)2 = 17; x = 14, x = 20
(x + 6)2 = 8; x equals negative 6 plus or minus 2 times the square root of 2
(x + 6)2 = 8; x = −14, x = 2
The correct option is: (x + 3)² = 17; x equals negative 3 plus or minus the square root of 17(x = -3 ± √17) by completing the square
How to evaluate for the equation by completing the squareThe completing the square method require we move constant term to the right hand side of the equation, divide the middle term and add its square to both sides of the equation as follows:
For the equation;
x² + 6x - 8 = 0
add 8 to both sides
x² + 6x = 8
divide 6 by 2 and add the square of the result to both sides
x² + 6x + 3² = 8 + 3²
by factorization;
(x + 3)² = 8 + 9
(x + 3)² = 17
x + 3 = ± √17 {take square root of both sides}
x = -3 ± √17
Therefore, by completing the square we the equation to be (x + 3)² = 17 and the solution for the value of x = -3 ± √17

9. A plant seed may get carried very far on a windy day, and sprout in another field full of the same type of
plant. What mechanism of evolution is this an example of? Explain.
As a result of the seed growing in a field with a different population of plants, we can witness how gene flow works in action.
It will have introduced its alleles into that population once this plant reproduces there. Any movement of people from one group to another—also known as migration—and/or the genetic material they carry is referred to as gene flow. Pollen being carried to a new location by the wind or individuals relocating to new cities or nations are just a few examples of the many different types of events that contribute to gene flow.
Vertical and horizontal gene flow are two different types of gene transfer. Gene flow describes the transfer of genetic material between groups.
