What is the smallest degree of rotation that will map a regular 15-gon onto itself?
Enter your answer in the box.
The correct answer is:
24°.
Explanation:
To find the degrees of rotational symmetry, you divide 360° by the order of symmetry.
For a regular 15-gon, the order of symmetry is 15 (there are 15 vertices that the polygon can be turned to and be mapped onto itself).
This means the degrees of symmetry would be
360/15 = 24°.
Answer:
24

a ferris wheel rotates around in 30 seconds. the maximum height above theground is 55 feet and the minumum height above the ground is 5 feet. what function would model the height as a funtion of T in seconds
Answer:
The required function is [tex]h(T)=30\sin (\frac{\pi T}{15})+25[/tex].
Step-by-step explanation:
The general sine function is
[tex]y=A\sin (Bx+C)+D[/tex] .... (1)
Where, A is amplitude, [tex]\frac{2\pi}{B}[/tex] is period, C is phase shift and D is midline.
It is given that the maximum height above the ground is 55 feet and the minimum height above the ground is 5 feet.
The amplitude of the function is
[tex]A=\frac{Maximum+Minimum}{2}=\frac{55+5}{2}=30[/tex]
The Midline of the function is
[tex]D=\frac{Maximum-Minimum}{2}=\frac{55-5}{2}=25[/tex]
A ferris wheel rotates around in 30 seconds. So, the period of the function is 30.
[tex]\frac{2\pi}{B}=30\Rightarrow B=\frac{2\pi}{30}=\frac{\pi}{15}[/tex]
[tex]2\pi=30B[/tex]
Substitute A=30, [tex]B=\frac{\pi}{15}[/tex], C=0 and D=25 in equation (1), to find the required function.
[tex]y=30\sin (\frac{\pi}{15}x+0)+25[/tex]
The required variable is T. Replace the variable x by T. So the height function is
[tex]h(T)=30\sin (\frac{\pi}{15}T+0)+25[/tex]
Therefore the required function is [tex]h(T)=30\sin (\frac{\pi T}{15})+25[/tex].

Steve’s car manual says his car does 42 mpg. A gallon is 4.55 litres. A litre of diesel costs £1.38. Steve drives from Leeds to Edinburgh a distance of 215 miles. How much would it cost for diesel
To calculate the cost of diesel for Steve's trip from Leeds to Edinburgh, divide the distance by the car's mpg to find the number of gallons needed. Then, multiply the gallons by the cost of diesel per gallon to get the total cost.
Explanation:To determine the cost of diesel for Steve's trip, we need to calculate the number of gallons he will need and then multiply by the cost per gallon. Steve's car does 42 miles per gallon (mpg), and he is driving a distance of 215 miles. Therefore, he will need 215/42 = 5.12 gallons of diesel. Since a gallon is 4.55 liters, Steve will need 5.12 * 4.55 = 23.36 liters of diesel. The cost of diesel per liter is £1.38, so the total cost for diesel will be 23.36 * £1.38 = £32.19.

Jose has determined he needs to have $800,000 for retirement in 30 years. His account earns 6% interest.
a.How much would you need to deposit in the account each month?
b.How much total money will you put into the account?
c.How much total interest will you earn?
a) Monthly deposit: $1,493.20. b) Total deposit: $537,552. c) Total interest earned: $262,448.
To solve these questions, we can use the formula for the future value of an annuity:
[tex]\[ FV = P \times \frac{{(1 + r)^n - 1}}{r} \][/tex]
Where:
[tex]- \( FV \)[/tex] is the future value of the annuity (the amount Jose wants to have at retirement).
[tex]- \( P \)[/tex] is the monthly deposit.
[tex]- \( r \)[/tex] is the monthly interest rate.
[tex]- \( n \)[/tex] is the total number of payments (number of years multiplied by 12, as there are 12 months in a year).
Given:
[tex]- \( FV = \$800,000 \)[/tex]
[tex]- \( r = 0.06/12 = 0.005 \) (monthly interest rate)[/tex]
[tex]- \( n = 30 \times 12 = 360 \)[/tex]
a) To find [tex]\( P \)[/tex]:
[tex]\[ P = \frac{{FV \times r}}{{(1 + r)^n - 1}} \][/tex]
Substitute the values:
[tex]\[ P = \frac{{800000 \times 0.005}}{{(1 + 0.005)^{360} - 1}} \][/tex]
Calculate [tex]\( P \):[/tex]
[tex]\[ P ≈ \frac{{4000}}{{(1.005)^{360} - 1}} ≈ \$1,493.20 \][/tex]
So, Jose needs to deposit approximately $1,493.20 each month.
b) Total money put into the account:
[tex]\[ Total\,Money = P \times n \][/tex]
Substitute the values:
[tex]\[ Total\,Money = \$1,493.20 \times 360 ≈ \$537,552 \][/tex]
Jose will put approximately $537,552 into the account over the 30 years.
c) Total interest earned:
[tex]\[ Total\,Interest = FV - Total\,Money \][/tex]
Substitute the values:
[tex]\[ Total\,Interest = \$800,000 - \$537,552 = \$262,448 \][/tex]
Jose will earn approximately $262,448 in total interest over the 30 years.

fg-9h=10j solve for g
It should be noted that when g is made the subject of the formula in fg - 9h = 10j, g will be g = (10j - 9h) / f.
How to illustrate the information?It should be noted that an equation is used to show the relationship that exist between the variables that are illustrated.
Based on the information, it should be noted that we want to make g the subject of the formula. This will be illustrated as:
fg - 9h = 10j
Add 9 h to both sides
fg - 9h + 9h = 10j - 9h.
fg = 10j - 9h.
Divide through by f
fg / f = (10j - 9h) / f
g = (10j - 9h) / f
In this case, it should be noted that when g is made the subject of the formula in fg - 9h = 10j, g will be g = (10j - 9h) / f.

Joe painted 1/4 of a bedroom in 1/2 a day. How many days will it take for Joe to paint one bedroom?
Final answer:
Joe painted a quarter of a bedroom in half a day, so it would take him 2 days to paint the entire bedroom.
Explanation:
If Joe painted ¼ of a bedroom in ½ a day, we can determine that to paint the entire bedroom, it would take four times as long since a full bedroom is four times as much as one quarter. Multiplying ½ day by 4, we get:
½ day * 4 = 2 days
Therefore, it will take Joe 2 days to paint the whole bedroom. Understanding the proportionality between the fraction of work completed and the time required enables accurate estimation of the total time needed for a task.
This logical approach simplifies complex problems and aids in efficient planning and resource management.

The price of an item has been reduced by 55%. The original price was $75. What is the price of the item now?
Final answer:
To calculate the new price of an item after a 55% reduction from an original price of $75, you multiply $75 by 55% to get the reduction amount of $41.25. Subtracting this from the original price gives a new price of $33.75.
Explanation:
The student is asking how to calculate the new price of an item after a percentage decrease, specifically a 55% reduction from the original price. To find the new price, we can apply the percentage decrease to the original price and then subtract that amount from the original price.
Original price = $75
Percentage decrease = 55%
First, calculate the amount of the reduction:
Reduction amount = (Original price) × (Percentage decrease)
Reduction amount = $75 × 0.55
Reduction amount = $41.25
Now, subtract the reduction amount from the original price to get the new price:
New price = Original price - Reduction amount
New price = $75 - $41.25
New price = $33.75
So the new price of the item after a 55% reduction is $33.75.
