The track consists of two straight lines (top and bottom) and two curve lines (right and left).
We will find the perimeter of the figure and multiply it by '2' since Noah ran around the track two times.
We know the curved region is half of a circle. So, we will find the length of this curved part by using the circumference of half circle formula.
Note: the Diameter (d) of the circle is 10 ft
Let's find the perimeter:Bottom = 10 ft
Top = 10 ft
Right =
\(C_{\text{half}}=\frac{\pi d}{2}=\frac{\pi(10)}{2}=5\pi\)Left =
\(C_{\text{half}}=\frac{\pi d}{2}=\frac{\pi(10)}{2}=5\pi\)Thus, the perimeter is
\(\begin{gathered} P=10+10+5\pi+5\pi \\ P=20+10\pi \end{gathered}\)Let's multiply this by 2, so we get:
\(\begin{gathered} 2\times(20+10\pi) \\ =40+20\pi \end{gathered}\)Using a calculator, we find the answer:
\(40+20\pi\approx102.83\)Rounded to the nearest whole number,

A gazebo in the shape of a regular octagon has equal sides of 9 feet and an apothem of 10.9 feet.
a. If one side of a gazebo is open, and the other sides have a railing, find the cost of the railing if it sells for $7.90 per foot.
b. Find the area of the gazebo in square feet.
c. Find the cost of the gazebo's flooring if it costs $3 per square foot. Round to the nearest hundred dollars.
Answer:
a) $497.70
b) 392.4 square feet
c) $1,200
Step-by-step explanation:
Part (a)A regular octagon has 8 sides of equal length.
Given each side of the octagon measures 9 feet in length, and one side does not have a railing, the total length of the railing is 7 times the length of one side:
\(\textsf{Total length of railing}=\sf 7 \times 9\; ft=63\;ft\)
If the railing sells for $7.90 per foot, the total cost of the railing can be calculated by multiplying the total length by the cost per foot:
\(\textsf{Total cost of railing}=\sf 63\;ft \times \dfrac{\$7.90}{ft}=\$497.70\)
Therefore, the cost of the railing is $497.70.
\(\hrulefill\)
Part (b)To find the area of the regular octagonal gazebo, given the side length and apothem, we can use the area of a regular polygon formula:
\(\boxed{\begin{minipage}{6cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{n\;s\;a}{2}$\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the length of one side.\\ \phantom{ww}$\bullet$ $a$ is the apothem.\\\end{minipage}}\)
Substitute n = 8, s = 9, and a = 10.9 into the formula and solve for A:
\(\begin{aligned}\textsf{Area of the gazebo}&=\sf \dfrac{8 \times 9\:ft \times10.9\:ft}{2}\\\\&=\sf \dfrac{784.8\;ft^2}{2}\\\\&=\sf 392.4\; \sf ft^2\end{aligned}\)
Therefore, the area of the gazebo is 392.4 square feet.
\(\hrulefill\)
Part (c)To calculate the cost of the gazebo's flooring if it costs $3 square foot, multiply the area of the gazebo found in part (b) by the cost per square foot:
\(\begin{aligned}\textsf{Total cost of flooring}&=\sf 392.4\; ft^2 \times \dfrac{\$3}{ft^2}\\&=\sf \$1177.2\\&=\sf \$1200\; (nearest\;hundred\;dollars)\end{aligned}\)
Therefore, the cost of the gazebo's flooring to the nearest hundred dollars is $1,200.
a. To find the perimeter of the gazebo, we can use the formula P = 8s, where s is the length of one side. Substituting s = 9, we get:
P = 8s = 8(9) = 72 feet
Since one side is open, we only need to find the cost of railing for 7 sides. Multiplying the perimeter by 7, we get:
Cost = 7P($7.90/foot) = 7(72 feet)($7.90/foot) = $4,939.20
Therefore, the cost of the railing is $4,939.20.
b. To find the area of the gazebo, we can use the formula A = (1/2)ap, where a is the apothem and p is the perimeter. Substituting a = 10.9 and p = 72, we get:
A = (1/2)(10.9)(72) = 394.56 square feet
Therefore, the area of the gazebo is 394.56 square feet.
c. To find the cost of the flooring, we need to multiply the area by the cost per square foot. Substituting A = 394.56 and the cost per square foot as $3, we get:
Cost = A($3/square foot) = 394.56($3/square foot) = $1,183.68
Rounding to the nearest hundred dollars, the cost of the flooring is $1,184. Therefore, the cost of the gazebo's flooring is $1,184.

A real estate agent received a 5.5% commission on the sale of a home. If her
commission was $14,960, how much did the home sell for?
The amount of the sale of the home is $2090181.82
How to determine how much the home sells for?From the question, we have the following parameters that can be used in our computation:
Commission = 5.5% on the sale of a home
Also, we have
Commission = 114960
using the above as a guide, we have the following:
5.5% on the sale of a home = 114960
So, we have
5.5% * sale of a home = 114960
Divide both sides by 5.5%
sale of a home = 114960/(5.5%)
Evaluate
sale of a home = 2090181.82
Hence, the sale of the home is $2090181.82

How do I find the possible degree(s) of a function from the graph alone?
Answer:
To determine the possible degree(s) of a function from the graph alone, you need to examine the behavior of the graph at the extremes (far left and far right) and consider the number of turning points or changes in direction. Here's a step-by-step approach:
Look at the far left side of the graph: Determine the behavior of the graph as it approaches negative infinity. Does the graph approach a specific value, such as a horizontal line (asymptote) or the x-axis? If the graph approaches a horizontal line, it suggests a polynomial function of even degree. If the graph approaches the x-axis, it indicates a polynomial function of odd degree or possibly a function with a root of multiplicity greater than one.
Look at the far right side of the graph: Determine the behavior of the graph as it approaches positive infinity. Similar to step 1, observe if the graph approaches a specific value or a horizontal line. The behavior at the far right side should be consistent with the behavior at the far left side. This can help you identify if the function is even or odd degree.
Examine the number of turning points or changes in direction: Count the number of times the graph changes direction. These points are where the slope of the graph changes from positive to negative or vice versa. The number of turning points can provide an indication of the degree of the polynomial. For example, if there are two turning points, it suggests a polynomial function of degree 3.
Remember that this method provides potential degrees, but it may not definitively determine the exact degree of the function. Additional information or analysis might be required for a more accurate determination.

A lumber company is making boards that are 2857.0 millimeters tall. If the boards are too long they must be trimmed, and if the boards are too short they cannot be used. A sample of 16 is made, and it is found that they have a mean of 2858.7 millimeters with a variance of 100.00. A level of significance of 0.05 will be used to determine if the boards are either too long or too short. Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the boards are either too long or too short
Answer:
The test statistic 't' = 0.68 < 2.1314 at 0.05 level of significance
Null Hypothesis is accepted
There is no sufficient evidence to support the claim that the boards are either too long or too short
Step-by-step explanation:
Step(i):-
Mean of the Population (μ) = 2857.0 millimetres
size of the sample 'n' = 16
Mean of the sample (x⁻) = 2858.7 millimetres
The Variance of the sample (S²)= 100.00
Standard deviation of the sample (S) = √100 =10
Degrees of freedom = n-1 =16-1 =15
Level of significance =0.05
Tabulated value = \(t_{\frac{0.05}{2} , 15} = t_{0.025,15} = 2.1314\)
Step(ii):-
Null Hypothesis :H₀ : There is no sufficient evidence to support the claim that the boards are either too long or too short
Alternative Hypothesis: H₁:There is sufficient evidence to support the claim that the boards are either too long or too short
Test statistic
\(t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }\)
\(t = \frac{2858.7 -2857}{\frac{10}{\sqrt{16} } }\)
t = 0.68
The calculated value = 0.68 < 2.1314 at 0.05 level of significance
Null Hypothesis is accepted
Final answer:-
There is no sufficient evidence to support the claim that the boards are either too long or too short

Heather wanted to study how the area of a rectangle changes with the length if its width is fixed. She computed the areas of several rectangles that have the same width and different lengths. She then plotted the results and connected them with a line, as shown below. The graph shows the area (in mm2) versus the length (in mm).Find the range and the domain of the function shown.
Let x and y be the length and area of the rectangle, respectively.
The arrow at the end of the line implies that it keeps growing indefinitely; therefore the range of the function is
\(\text{range}=\mleft\lbrace y\in\R|y\ge0\mright\rbrace=y\ge0\)Where we considered that the minimum of the function is at (0,0).
Similarly, the minimum value that x can take is zero because it is a length; then, the domain of the function is
\(\text{domain}=\mleft\lbrace x\in\R|x\ge0\mright\rbrace=x\ge0\)The range is y>=0 and the domain is x>=0

A building is being constructed. When completed, it will be 596 meters tall. It currently stands at 77% of this height.
Which is the best estimate for the current height of the building?
400 meters
350 meters
480 meters
450 meters
Answer:
450 meters
Step-by-step explanation:
77% or 0.77
596 × 0.77 = 458.92
458.92 ≈ 459 ≈ 450 meters
Double Check: 100% - 77% = 23% or 0.23
596 × 0.23 = 137.08
137.08 + 458.92 = 596
For the third week of April, Patricia Thomas worked 53 hours. Patricia earns $11.90 an hour. Her employer pays overtime for all hours worked in excess of 40
hours per week and pays 1.5 times the hourly rate for overtime hours.
Calculate the following for the third week of April (round your responses to the nearest cent if necessary):
1. Regular pay amount
2. Overtime pay
3. Gross pay
Given statement solution is :- For the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.
To calculate Patricia's pay for the third week of April, we'll need to determine her regular pay, overtime pay, and gross pay.
Regular Pay:
Patricia worked 53 hours, but only 40 hours are considered regular hours. Therefore, the regular pay is calculated as follows:
Regular Pay = Regular Hours x Hourly Rate
Regular Pay = 40 hours x $11.90/hour
Regular Pay = $476
Overtime Pay:
Since Patricia worked 53 hours in total and 40 of those are regular hours, the remaining 13 hours are considered overtime hours. Overtime pay is calculated by multiplying the overtime hours by 1.5 times the hourly rate.
Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)
Overtime Pay = 13 hours x ($11.90/hour x 1.5)
Overtime Pay = 13 hours x $17.85/hour
Overtime Pay = $231.45
Gross Pay:
Gross Pay is the sum of Regular Pay and Overtime Pay.
Gross Pay = Regular Pay + Overtime Pay
Gross Pay = $476 + $231.45
Gross Pay = $707.45
Therefore, for the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.

Determine whether each of the following functions is even, odd, or neither even nor odd.
(a) f(x) = 1 + 3x 2 − x 4
(b) ????(????) = ???? ???? ????+�
Answer:
A.) Even.
Step-by-step explanation:
If a function is an even function, then
F(-x) = f(x)
Also, if a function is an odd function, then, f(-x) = -f(x)
You are given the below function
f(x) = 1 + 3x^2 − x^4
Let x = 2
Substitute 2 for x in the function
F(x) = 1 + 3(2)^2 - (2)^4
F(x) = 1 + 3(4) - 16
F(x) = 1 + 12 - 16
F(x) = -3
Also, Substitute -2 for x in the function
F(x) = 1 + 3(-2)^2 - (-2)^4
F(x) = 1 + 3(4) - 16
F(x) = 1 + 12 - 16
F(x) = -3
Since f(-x) = f(x), we can conclude that
F(x) = 1 + 3x^2 - x^4 is even

(Show work)
Answer:
Tamara's monthly salary was $ 1,190.95.
Step-by-step explanation:
Given that Tamara receives a salary of $ 875 plus 71/4% of all her monthly sales above $ 400, to determine how much money she earned in the month knowing that she made sales for $ 2,180, the following calculation must be performed:
2180 - 400 = 1780
71/4 = 17.75
1780 x 17.75 / 100 = 315.95
315.95 + 875 = X
1,190.95 = X
Thus, Tamara's monthly salary was $ 1,190.95.
