Approximately 1978 ft a passenger travel during a 5-minute ride and this can be determined by using the formula of the perimeter of a circle.
Given :
A Ferris wheel has a diameter of 42 feet. It rotates 3 times per minute.
The following steps can be used in order to determine the total distance travel by the passenger during a 5 minutes ride:
Step 1 - First determine the perimeter of the circle. The formula of the perimeter of the circle is given by:
[tex]\rm C = 2\pi r[/tex]
Step 2 - Now, substitute the value of known terms in the above formula.
[tex]\rm C=2\pi\times(21)[/tex]
[tex]\rm C= 131.94\;ft[/tex]
Step 3 - In one minute passenger travels:
[tex]\rm =131.94\times 3=395.82\; ft[/tex]
Step 4 - So, in three minutes passenger travels:
[tex]=395.82\times5[/tex]
= 1978 ft
So, approximately 1978 ft a passenger travel during a 5-minute ride.

Double vision can be the result of _________________.
Wearing glasses that are too strong
Looking directly into bright headlights Passing other cars
Eye muscles relaxed from fatigue, drugs, or alcohol
Rapid eye blinking
Final answer:
Double vision can be caused by wearing glasses that are too strong, eye muscles being relaxed from fatigue, drugs, or alcohol, or by rapid eye blinking. Nearsightedness and farsightedness are common vision defects related to the eye's focusing ability but do not usually cause double vision, which can also be a result of misalignment.
Explanation:
Double vision can be the result of several factors including wearing glasses that are too strong, eye muscles relaxed from fatigue, drugs, or alcohol, or rapid eye blinking. It is not typically caused by looking directly into bright headlights or the action of passing other cars, which are more likely to cause temporary glare or flash blindness rather than persistent double vision.
Common vision defects such as nearsightedness (myopia) and farsightedness (hyperopia) are related to the focusing ability of the eyes. Myopia occurs when the eye over-converges the rays from a distant object in front of the retina, causing distant objects to appear blurry. Hyperopia, on the other hand, happens when the eye does not converge rays from a close object sufficiently, making close objects appear blurry. Misalignment can also cause double vision, and this can be due to a variety of factors including strabismus or nerve damage. Correction of vision defects often involves the use of glasses or contact lenses with the appropriate lens power or surgery for more severe cases.

A coin collector bought a set of coins for $500, and then sold the set for $850, making a profit of $50 per coin. how many coins were in the set?
For this case, the first thing we must do is calculate the total profit.
We have then:
[tex] P = 850 - 500 [/tex]
[tex] P = 350 [/tex]
Then, we look for the number of coins.
For this, we need the total profit (which we already calculate) and the amount of profit per coin.
We have then:
[tex] N = \frac{350}{50} [/tex]
[tex] N = 7 [/tex]
Answer:
The amount of coins that was on the set is:
[tex] N = 7 [/tex]
Final answer:
The coin collector bought and sold a set of coins, making a total profit of $350. Dividing this profit by the $50 profit per coin reveals that there were 7 coins in the set.
Explanation:
The coin collector made a profit of $50 per coin by selling a set of coins. To find out how many coins were in the set, we need to calculate the total profit made from selling the coins and then divide that by the profit per coin.
The total profit is the selling price minus the buying price, so $850 - $500 = $350. If the collector made $50 profit per coin, then the number of coins in the set can be found by dividing the total profit by the profit per coin: $350 / $50 per coin = 7 coins.
If 35% of a natural area is to be developed, leaving 500 acres untouched, how many acres are to be developed?
Answer:
Area to be developed = 269.23 acres
Step-by-step explanation:
Let there is A acres natural area to be developed.
If 35% of A acres is developed then untouched area will be (100 - 35 = 65%)
Now it has been given in the question that 65% of A (untouched area) = 500 acres
[tex]A.\frac{65}{100}=500[/tex]
[tex]A=\frac{500}{0.65}=769.23[/tex]
So area of the natural field = 769.23 acres
Now 35% of the natural area which is to be developed = A×35%
[tex]=769.23.\frac{35}{100}=(769.23)(.35)=269.23[/tex]
Area of the natural area to be developed is 269.23 acres
The number of acres that are to be developed is 269 acres.
Number of acresUsing this formula
Number of acres=(Number of acres untouched/(100%-Percentage of natural area)×Percentage of natural area
Let plug in the formula
Number of acres=500 acres/(100%-35%)×35%
Number of acres=(500 acres/65%)×35%
Number of acres=769.23×35%
Number of acres=269 acres
Inconclusion the number of acres that are to be developed is 269 acres.

Find the missing factor x(y+6)-5(y+6)( ) (y+6)
We are given the equation:
x (y + 6) – 5 (y + 6) ---> 1
We are to look for the missing factor in the equation: (_) (y + 6) from the given values.
Knowing the rules of the polynomial multiplicity, we can have an idea that the given equation can also be written in the form of:
(x – 5) (y + 6) ---> 2
wherein the whole factor (y + 6) was simply distributed to the values in the factor (x – 5). To prove that equations 1 and 2 are equal:
x (y + 6) – 5 (y + 6) = (x – 5) (y + 6)
Expanding:
x y + 6 x - 5 y – 30 = x y + 6 x – 5 y – 30 (EQUAL!)
Therefore our missing factor is:

True or false? the point at which a tangent line meets a circle is called the point of tangency
Final answer:
The statement is true; a tangent line meets a circle at the point of tangency, which is the unique point where the tangent touches the circle without intersecting it.
Explanation:
True, the point at which a tangent line meets a circle is indeed called the point of tangency. This is a fundamental concept in geometry, where a tangent line is defined as a line that touches a curve at exactly one point, without crossing through it. This distinct point is known as the point of tangency.
For example, if we have a circle and a line that touches the circle at just one point and does not intersect it at that point, that line is a tangent to the circle, and the point of contact is the point of tangency. The tangent line is always perpendicular to the radius of the circle at the point of tangency, as can also be seen from the properties of the director circle, which is the locus of points of intersection of perpendicular tangents to the curves like ellipses and hyperbolas.
In the context of a director circle, perpendicular tangents to an ellipse would intersect on this special circle. Although for this particular question, we are focusing on the tangent line to a single circle and its point of tangency. It's interesting to note that according to the properties of circles, every point on a circle allows for exactly one tangent line. Whenever such a line is drawn, it illustrates the concept of tangency.

He nine ring wraiths want to fly from barad-dur to rivendell. rivendell is directly north of barad-dur. the dark tower reports that the wind is coming from the west at 68 miles per hour. in order to travel in a straight line, the ring wraiths decide to head northwest. at what speed should they fly (omit units)?
This problem is better understood with a given figure. Assuming that the flight is in a perfect northwest direction such that the angle is 45°, therefore I believe I have the correct figure to simulate the situation (see attached).
Now we are asked to find for the value of the hypotenuse (flight speed) given the angle and the side opposite to the angle. In this case, we use the sin function:
sin θ = opposite side / hypotenuse
sin 45 = 68 miles per hr / flight
flight = 68 miles per hr / sin 45
flight = 96.17 miles per hr

Match the functions with their inverse functions.
We know that when we are given a inverse function as: [tex]f^{-1}(x)[/tex]
Then we find the function by the method:
Put [tex]f^{-1}(x)=y[/tex]
Then we switch the places of x and y and solve for y.
1)
[tex]f^{-1}(x)=\dfrac{2x-3}{5}[/tex]
Hence, we find the function as follows:
[tex]\dfrac{2x-3}{5}=y[/tex]
Then we switch for x and y
[tex]\dfrac{2y-3}{5}=x\\\\\\i.e.\\\\2y-3=5x\\\\\\i.e.\\\\\\2y=5x+3\\\\\\i.e.\\\\\\y=\dfrac{5x+3}{2}[/tex]
Hence, inverse function is:
[tex]f(x)=\dfrac{5x+3}{2}[/tex]
2)
[tex]f^{-1}(x)=\dfrac{x+8}{2}[/tex]
Hence, we find the function as follows:
[tex]\dfrac{x+8}{2}=y[/tex]
Then we switch for x and y
[tex]\dfrac{y+8}{2}=x[/tex]
[tex]y=2x-8[/tex]
Hence, inverse function is:
[tex]f(x)=2x-8[/tex]
3)
[tex]f^{-1}(x)=\dfrac{x+2}{7}[/tex]
Hence, we find the function as follows:
[tex]\dfrac{x+2}{7}=y[/tex]
Then we switch for x and y
[tex]\dfrac{y+2}{7}=x[/tex]
[tex]y=7x-2[/tex]
Hence, inverse function is:
[tex]f(x)=7x-2[/tex]
4)
[tex]f^{-1}(x)=\dfrac{1-2x}{x}[/tex]
Hence, we find the function as follows:
[tex]\dfrac{1-2x}{x}=y[/tex]
Then we switch for x and y
[tex]\dfrac{1-2y}{y}=x[/tex]
i.e.
[tex]1-2y=xy\\\\xy+2y=1\\\\i.e.\\\\y(x+2)=1\\\\y=\dfrac{1}{x+2}[/tex]
Hence, inverse function is:
[tex]f(x)=\dfrac{1}{x+2}[/tex]

Fill in the missing term in the equation. x/x^2-4x+4-x/x^2-3x+2=?/(x-2)^2(x-1)
Answer:
The missing term is x.
Step-by-step explanation:
Given expression is,
[tex]\frac{x}{x^2-4x+4}-\frac{x}{x^2-3x+2}------(1)[/tex]
Since, [tex]x^2-4x+4=(x)^2-2\times (2x)+(2)^2[/tex]
[tex]\implies x^2-4x+4=(x-2)^2------(2)[/tex] ( (a-b)² = a² - 2ab + b² )
Now, [tex]x^2-3x+2=x^2-2x-x+2[/tex] ( By middle term splitting )
[tex]=x(x-2)-1(x-2)[/tex]
[tex]\implies x^2-3x+2=(x-1)(x-2)------(3)[/tex]
From equation (1), (2) and (3),
[tex]\frac{x}{x^2-4x+4}-\frac{x}{x^2-3x+2}=\frac{x}{(x-2)^2}-\frac{x}{(x-2)(x-1)}[/tex]
[tex]=\frac{x(x-1)-x(x-2)}{(x-2)^2(x-1)}[/tex]
[tex]=\frac{x(x-1-x+2)}{(x-2)^2(x-1)}[/tex]
[tex]=\frac{x(1)}{(x-2)^2(x-1)}[/tex]
[tex]=\frac{x}{(x-2)^2(x-1)}[/tex]
Hence, the missing term in the equation is x.
