When you let go of the railing on the merry-go-round at the skateboard park, your path of motion will be tangential to the circular path. For the Ferris wheel, your path will be parabolic due to the influence of gravity.
When you let go of the railing on the merry-go-round at the skateboard park, your motion will follow the principle of inertia. Since there is no friction to slow you down, your path of motion will be tangential to the circular path at the moment you let go. This means you will continue moving in a straight line tangent to the circular path.
In the case of a Ferris wheel, when you let go of the railing, gravity comes into play. Your path of motion will follow a parabolic trajectory due to the influence of gravity. As you fall, your path will curve downward, creating a parabolic shape.
The exact shape and position of the parabolic path will depend on factors such as your initial position, speed, and the size of the Ferris wheel. To sketch the path of your fall for at least one position in each quadrant, you would need specific information about the Ferris wheel's dimensions and your initial position.

Using the same trigonometric function, express the cos 115 degrees as a function of a positive acute angle
we can express cos 115 degrees as cos 25 degrees, which is a function of a positive acute angle
To express cos 115 degrees as a function of a positive acute angle, we can use the concept of reference angles.
The reference angle is the positive acute angle formed between the terminal side of an angle and the x-axis. It is the smallest angle between the terminal side and the x-axis.
To find the reference angle for 115 degrees, we subtract 90 degrees from 115 degrees:
Reference angle = 115 degrees - 90 degrees = 25 degrees
Since cosine is an even function, the cosine of the reference angle will be the same as the cosine of the original angle:
cos 115 degrees = cos 25 degrees
Therefore, we can express cos 115 degrees as cos 25 degrees, which is a function of a positive acute angle.

On Thursday, she hiked with a friend for 4 miles. On Saturday, she hiked for 5 miles. On Sunday, she hiked for 4 miles. If she hiked a total of 340 minutes all week and it takes her the same amount of time to hike each mile, how many minutes does it take her to hike each mile?
If Tamara hiked a total of 340 minutes and her goal is to hike for at least 350 minutes every week, it means she fell short by 10 minutes.
Since it takes her the same amount of time to hike each mile, we can calculate the time it takes her to hike each mile.
On Thursday, she hiked a total of 1 + 3 + 4 = 8 miles. On Saturday and Sunday, she hiked a total of 5 + 4 = 9 miles. So in total, she hiked 8 + 9 = 17 miles.
To find the time it takes her to hike each mile, we divide the total time she hiked (340 minutes) by the total distance she covered (17 miles). Therefore, it takes her 340/17 = 20 minutes to hike each mile.

Your bathtub holds 80 gallons of water. The cold faucet adds water to the tub at 2142 and 1 fourth gallons per minute. The hot water faucet adds water to the tub at 1121 and 1 half gallon per minute. The drain lets water out at a rate of 343 over 4 gallon per minute. You start the bath by turning both faucets on, but forget to close the drain. The tub fills in 27 minutes. How large is the bathtub?
How will you solve the question?
To determine the size of the bathtub, we can use the information provided about the fill rate of the cold and hot water faucets, the drain rate, and the time it takes to fill the tub. The size of the bathtub is 42,471 gallons.
To determine the size of the bathtub, we can use the information provided about the fill rate of the cold and hot water faucets, the drain rate, and the time it takes to fill the tub. By subtracting the drain rate from the combined fill rate of the faucets and multiplying it by the time, we can find the net fill rate. Dividing the total amount of water filled in the given time by the net fill rate will give us the size of the bathtub.
First, we calculate the net fill rate per minute: (2142 1/4 + 1121 1/2) - (343/4) = 2142 1/4 + 1121 1/2 - 343/4.
Next, we multiply the net fill rate per minute by the time in minutes (27) to find the total water filled in that time.
To compute the net fill rate per minute, we need to convert the mixed numbers to improper fractions and perform the necessary calculations:
2142 1/4 + 1121 1/2 - 343/4 = 2149/4 + 2243/2 - 343/4 = 2149/4 + 4486/4 - 343/4 = (2149 + 4486 - 343)/4 = 6292/4 = 1573/1 = 1573.
The net fill rate per minute is 1573 gallons.
Next, we calculate the total water filled in 27 minutes:
Total water filled = net fill rate per minute × time in minutes = 1573 × 27 = 42,471 gallons.
Therefore, the size of the bathtub is 42,471 gallons.

given solid of hemisphere and cylinder having total height 35 cm and radius is 7 cm find the volume of solid
Given a solid of hemisphere and cylinder having a total height 35 cm and radius 7 cm, the volume of the solid is 6105.19 cm³.
So the volume of the solid is 6105.19 cm³.
To begin with, we must identify the volume of each hemisphere and cylinder before we can add them up to find the volume of the entire solid.
The volume of a hemisphere of radius r is given by the formula;
V = 2/3πr³
And the volume of a cylinder of radius r and height h is given by;
V = πr²h
Hence, the volume of the hemisphere with radius 7cm will be;
V₁ = 2/3π(7)³
= 718.81cm³
And the volume of the cylinder with radius 7cm and height 35cm will be;
V₂ = π(7)²(35)
= 5386.38cm³
The volume of the entire solid is given by the sum of the volumes of the hemisphere and cylinder.
V = V₁ + V₂
= 718.81 + 5386.38

The best fit line for the data collected from 2007 to 2014 is represented by the equation Y = 0.15x + 8.27.
To determine the best fit line, we utilize linear regression analysis, which aims to find the line that minimizes the overall distance between the line and the data points. In this case, the equation of the best fit line is in the form Y = mx + b, where "m" represents the slope and "b" represents the y-intercept.
Given the equation Y = 0.15x + 8.27, we can interpret it as follows:
The slope (m) of 0.15 indicates that for every unit increase in the independent variable (x), the dependent variable (Y) increases by 0.15 units.
The y-intercept (b) of 8.27 indicates that when x is zero (2007 in this case), the expected value of Y is 8.27.
Therefore, the equation Y = 0.15x + 8.27 represents the best fit line for the data collected from 2007 to 2014, where Y represents the dependent variable (museum collections) and x represents the independent variable (years).

Then, he spent 1/2 of the remaining amount on rent, leaving him with 1/2 * (3/5) = 3/10 of his salary.
Finally, he spent 1/4 of what still remained on drinks, leaving him with 3/10 * (3/4) = 9/40 of his salary.
We are given that Yaw still had ¢80 left, which represents 9/40 of his salary:
(9/40)S = ¢80
To find S, we can solve the equation:
S = (¢80 * 40) / 9
S ≈ ¢355.56
Therefore, Yaw's monthly salary is approximately ¢355.56.
b. Yaw spent 2/5 of his salary on food. Substituting the value of S we found in part a:
(2/5) * ¢355.56 = ¢142.22
Yaw spent approximately ¢142.22 on food.
c. Yaw spent 1/2 of the remaining amount on rent. Substituting the value of S we found in part a:
(1/2) * (3/10) * ¢355.56 = ¢53.34
Yaw spent approximately ¢53.34 on rent.
Therefore, Yaw spent approximately ¢142.22 on food and ¢53.34 on rent.

the example of a permutation is: A) The number of ways 3 people can win 3 different prizes.
A) The number of ways 3 people can win 3 different prizes.
This scenario involves the arrangement of 3 people winning 3 different prizes. Since the order in which the people win the prizes matters, this is an example of a permutation. For instance, if we have three people named A, B, and C, the possible permutations of them winning the prizes could be A winning the first prize, B winning the second prize, and C winning the third prize. Therefore, option A is an example of a permutation.
B) Picking 10 CDs to lend to a neighbor from a collection of 35.
This scenario involves selecting 10 CDs out of a collection of 35. The order in which the CDs are selected does not matter; only the selection itself is important. Therefore, this is an example of a combination rather than a permutation. Option B does not represent a permutation.

The stocks have a yield 6. 43 percentage points greater than that of the bonds. B. The stocks have a yield 6. 84 percentage points greater than that of the bonds. C. The bonds have a yield 1. 05 percentage points greater than that of the stocks. D. The bonds have a yield 9. 13 percentage points higher than that of the stocks.
The stocks of Cawh Consolidated Bank offer a yield that is 6.84 percentage points greater than that of the bonds.
To compare the yields of Edgar's investment in Cawh Consolidated Bank stocks and bonds, we need to calculate the yields of both investments and then find the difference between them.
For the stocks, the yield can be calculated by dividing the annual dividend per share by the purchase price per share and multiplying by 100. In this case, the yield of the stocks is [tex][{\frac{3.15}{21.38}] *100= 14.71 \%.[/tex]
For the bonds, the yield is the annual interest payment divided by the market value of the bonds, multiplied by 100. The yield of the bonds is [tex][{\frac{8.3}{105.166}]* 100 = 7.89 \%[/tex] .
Now, to determine which aspect of Edgar's investment offers a greater percent yield, we find the difference between the yield of the stocks and the yield of the bonds. The difference is [tex]14.71 \% - 7.89 \% = 6.82 \%[/tex].
Therefore, the correct answer is option B: The stocks have a yield [tex]6.84[/tex]percentage points greater than that of the bonds.

In the study, palmitic acid was determined to be the most effective chemical, providing three times the protection of stearic acid and was ten percentage points higher in protection than linoleic acid. The effectiveness precentages of stearic acid plus linoleic acid together were five percentage points higher than palmitic acid. What is the effectiveness of stearic acid in repelling mosquitoes?
The effectiveness of stearic acid in repelling mosquitoes can be calculated by using the data given in the statement and the following formula.Effectiveness of Stearic Acid = (Effectiveness of stearic acid plus linoleic acid) - (Effectiveness of linoleic acid)
Substituting the given values, we get the effectiveness of stearic acid as: (Effectiveness of stearic acid + linoleic acid) - (Effectiveness of linoleic acid)=(5+10)−(Effectiveness of linoleic acid)=15 - Effectiveness of linoleic acidNow, it is given that palmitic acid was three times more effective than stearic acid.
Hence, the effectiveness of stearic acid can be written as: Effectiveness of stearic acid = 1/3 (Effectiveness of palmitic acid)Also, palmitic acid was 10% more effective than linoleic acid. Hence, the effectiveness of palmitic acid can be written as:Effectiveness of palmitic acid = 1.10
(Effectiveness of linoleic acid)Substituting the value of effectiveness of palmitic acid in the equation for effectiveness of stearic acid, we get:Effectiveness of stearic acid = 1/3 (Effectiveness of palmitic acid)= 1/3 x 1.10 (Effectiveness of linoleic acid)= 0.366 (Effectiveness of linoleic acid)

When the Foresthill Wildfire band returned from a recent competition, 24 of the students attended school before realizing they had contracted a strong flu virus. The virus quickly spread and each day the number of students with the flu increased by an estimated 30%. How many people will have the flu after five days?
The number of people who have the flu after 5 days is A = 88 people
Given data,
To calculate the number of people who will have the flu after five days, we need to consider that the number of students with the flu increases by 30% each day.
Let's start with the initial number of students who contracted the flu, which is 24.
After the first day, the number of students with the flu will increase by 30% of 24:
30% of 24 = (30/100) * 24 = 7.2
The exponential equation is represented as
x ( t ) = x₀ × ( 1 + r )ⁿ
So, x ( 5 ) = 24 ( 1.3 )⁵
On simplifying , we get
x ( 5 ) = A = 88 people
Hence , after five days, approximately 88 students will have the flu.

We have to estimate the allocation base and the total manufacturing overhead costs in advance in order to be able to determine a
In order to determine the predetermined overhead rate and allocate manufacturing overhead costs, it is necessary to estimate the allocation base and the total manufacturing overhead costs in advance.
These estimates help in establishing a systematic method for assigning overhead costs to products or services based on a relevant allocation base.
Manufacturing overhead costs include various indirect expenses such as factory rent, utilities, equipment maintenance, and supervision. These costs cannot be easily traced directly to specific products or services. Instead, they are allocated based on a predetermined overhead rate.
The allocation base is a measure or activity that serves as a common denominator for distributing overhead costs. Common allocation bases include direct labor hours, machine hours, or material costs. The choice of allocation base depends on the nature of the business and the activities that drive overhead costs.
To determine the predetermined overhead rate, the total estimated manufacturing overhead costs for a specific period are divided by the estimated allocation base. This rate is then applied to the actual allocation base incurred during production to allocate the overhead costs to individual products or services.
Estimating the allocation base and the total manufacturing overhead costs in advance allows for a more accurate and consistent allocation of overhead expenses. It helps businesses establish a systematic approach to assign costs, aiding in decision-making, cost analysis, and determining product or service pricing.

What is the value of q for which the lines qx−7y+10=20 and 4y+3x+9=0 are parallel to each other?
To determine the value of q for which the lines qx - 7y + 10 = 20 and 4y + 3x + 9 = 0 are parallel to each other, we need to compare their slopes.
First, we'll rewrite the equations in the standard form y = mx + b, where m represents the slope of the line:
For the line qx - 7y + 10 = 20, rearranging the equation gives us:
qx - 7y = 10
-7y = -qx + 10
y = (q/7)x - 10/7
For the line 4y + 3x + 9 = 0, rearranging the equation gives us:
4y = -3x - 9
y = (-3/4)x - 9/4
From the equations, we can see that the slopes are q/7 for the first line and -3/4 for the second line.
For two lines to be parallel, their slopes must be equal. Therefore, we can equate the slopes and solve for q:
q/7 = -3/4
Cross-multiplying, we have:
4q = -21
Dividing both sides by 4, we find:
q = -21/4
Therefore, the value of q for which the lines are parallel to each other is -21/4.
