A particle is moving on the perimeter of a circle with radius r=5 with angular speed of π/8 radians per second. After completing 4 full rotations, the particle traveled for 7 more seconds and stopped. What is the length of the total distance the particle traveled?
Answers
The length of the total distance the particle traveled is, 327π/8.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
We have to given that;
A particle is moving on the perimeter of a circle with radius r=5 with angular speed of π/8 radians per second.
Now, First of all, let's calculate the the circumference. This is found by this equation:
⇒ P = 2πr
Here, r = 5
⇒ P = 2π × 5
⇒ P = 10π
And, The distance of completing 4 full rotations is,
⇒ D = 4P
⇒ D = 4 × 10π
⇒ D = 40π
Since, In one second the particle traveled π/8 radians.
Here, the particle traveled for 7 more seconds and stopped, this distance is,
⇒ 7 (π/8)
⇒ 7π/8
Thus, the length of the total distance the particle traveled is;
⇒ 40π + 7π/8
⇒ 327π/8

56 parts were lost 3% of the total parts were lost. how many total parts were there
Answers
The total parts that were lost is 1867
How to determine the total parts that were lostLet's call the number of total parts "x".
From the question, we have the following parameters that can be used in our computation:
56 parts were lost, which is 3% of the total, so we can write:
56 = (3/100) * x
To isolate x, we can divide both sides by (3/100):
56 / (3/100) = x
Rewrite the equation as
x = 56/(3/100)
Express as product
So, we have
x = 56 * 100/3
Evaluate the product
x = approximately 1867
So there were approximately 1867 total parts.

a rectangular residential lot with the area 7475 is 50m longer then it is wide find the dimensions of the lot
Answers
The Area of path is 400cm of a rectangular residential lot with the area 7475 is 50m longer then it is wide.
What is area of the path?The difference between the areas of the two rectangles represents the path's area. To calculate the two areas, we shall utilize the rectangle's area formula. To get the necessary size of the path, first calculate the area of the larger rectangle by subtracting the area of the smaller rectangle.
In essence, the length and breadth of the rectangle multiplied together gives the area of the rectangle. In contrast, when we talk about a rectangle's perimeter, we mean the total of its four sides. Consequently, we can say that the area of a rectangle equals the space enclosed by its perimeter.
Area of park = l × b = 40 × 35 = 1350
Area of park with path is = 45 + 2.5 + 2.5 x 30 + 2.5 + 2.5 = 1750 cm
Therefore,
Area of path = Area of park with path - Area of rectangular park
= 1750 - 1350 = 400cm

if f(x) = f(xf(xf(x))), where f(1) = 4, f(4) = 6, f '(1) = 4, f '(4) = 5, and "f '(6) = 6", find f '(1).
Answers
If function F(x) = f(xf(xf(x))), where f(1) = 4, f(4) = 6, f '(1) = 4, f '(4) = 5, and f '(6) = 6, the value of an F'(1) is 114.
We know that the chain rule of differentiation (derivative)
The derivative of composite function f(g(x)) is: f'(g(x))⋅g'(x)
Consider function F(x) = f(xf(xf(x)))
We need to differentiate above function with respect to x.
F'(x) = f'(xf(xf(x))) × d/dx[x f(xf(x))]
We use product rule of derivative to find d/dx[x f(xf(x))]
d/dx[x f(xf(x))] = f(xf(x)) d/dx(x) + x d/dx(f(xf(x)))
After simplifying these expressions we get.
F'(x) = f'(xf(xf(x))) [f(xf(x)) + xf'(xf(x)) + x(f(x) + xf'(x))]
For x = 1 above expression would be,
F'(1) = f'(1 f(1 f(1))) [f(1 f(1)) + 1 f'(1 f(1)) + 1 (f(1) + 1 f'(1))]
F'(1) = f'(f(4)) [f(4) + f'(4) + (4 + 4)]
F'(1) = f'(6) [6 + 5 + 8]
F'(1) = 6 × 19
F'(1) = 114
Therefore, the value of F'(1) = 114.

Answers
The appropriate scale of measurement for an investor collecting data on the weekly closing price of gold throughout the year is:
a. Ratio
A ratio scale of measurement allows for meaningful comparisons of absolute differences between two values and the computation of ratios.
In the scenario of collecting weekly closing price data of gold, values such as "$1,000 per ounce" or "$2,000 per ounce" can be meaningfully compared to determine the ratio of change.
Using the ratio scale of measurement, it is possible to perform various statistical operations, such as mean, median, and standard deviation, which are meaningful and give us insights into the data.
For example, you can calculate the mean closing price for gold over a given period.
Additionally, the ratio scale allows for meaningful comparisons of magnitudes, such as "twice the value" or "half the value." Thus, a ratio scale is the most appropriate measurement scale in this scenario.

On solving the provided question we can say that we have the slope -5/7 and the equation will be 5x +7y -c = 0
what is slope?A line's slope determines how steep it is. A mathematical equation for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two spots. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is employed to express it. The y-intercept is located at a location where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).The line's slope is m. b is b at the point where the y-intercept is, and (0, b). As an illustration, the equation y = 3x - 7 has a slope of 3, and its y-intercept is (0, 7).

we have the slope -5/7
y = /5x/7 +c

After three years, its value would be $38,880 * (1 - 0.1) = $34,992.So, the amount Sally would have to pay off during her three-year lease is $48,000 - $34,992 = $13,008.In conclusion, the answer is d. $36,790.

so you can write the equation:
Player A = 2x - 653
This equation shows the relationship between the number of home runs player B had (x) and the number of home runs player A had (2x - 653). To find the number of home runs player B had, you can solve for x by adding 653 to both sides of the equation:
x = (Player A + 653) / 2
So if you know the number of home runs player A had, you can use this equation to find the number of home runs player B had.
29.Rewrite the equation so that y is a function of x:
3x + 5y = 15
30.Use the result in question #29 to find y when x = -1.
Answers
The equation so that y is a function of x is y = [15 - 3x]/5 and the value of y is 18/5.
What is a linear equation?Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.
Both linear equations with one variable and those with two variables exist.
Given the equation 3x + 5y = 15
to convert it in form of y,
5y = 15 - 3x
and divide both sides by 5
y = [15 - 3x]/5
substitute x = -1
y = [15 - 3x]/5
y = [15 - 3(-1)]/5
y = 18/5
Hence equation is y = [15 - 3x]/5 and y = 18/5.
