what kind of motion should you impart to the nozzle of a garden hose so that the resulting stream of water approximates a sine curve?
Answers
A periodic up-and-down motion should be imparted to the nozzle of a garden hose such that the resultant stream of water approximates a sine curve.
A sine curve is a mathematical function that oscillates between a maximum and minimum value in a repeating pattern. To approximate this with a stream of water from a garden hose, the nozzle of the hose should be moved in a periodic up-and-down motion. This motion will cause the water stream to oscillate between a higher and lower height, creating the repeating pattern characteristic of a sine curve. The speed at which the nozzle is moved, as well as the amplitude of the motion, can be adjusted to create a more accurate representation of a sine curve.
Also, the nozzle can be turned to make the water flow in a spiral, which looks even more like a sine curve.

What is the difference between real function and complex function?
Answers
A real function, usually referred to as a real-valued function, is one whose domain is the real numbers. A function from complex numbers to complex numbers is referred to as a complex function.
What is complex function?A true function is a prescription that gives values to its input parameters. According to the notation y = f (x), the function f assigns the value y to the argument's value x. Additionally, we occasionally write the function f as f: x y, which means that it sends x to y. A real function, usually referred to as a real-valued function, is one whose domain is the real numbers. The relation is a function if a vertical line only ever crosses the relation on the graph once in all locations. However, the relation is not a function if a vertical line passes across it more than once.

OPOT 99 feet. What will the length of the model be?
=1
A. 180 ft
B.
60 ft
C.
30 ft
D.

Answers
The correct answer is option B: 60 ft.
To find the length of the model, you can use the formula:
Length of model = (Length of original object) x (Scale factor)
The scale factor in this case is 99 feet / 6 inches = 16.5 feet/inch
So the length of the model = (6 inches) x (16.5 feet/inch) = 60 ft
What is the formula for enlargement?
Answers
The formula for enlargement = New length = original length × scale factor.
What is enlargement?
A shape's size can be changed by enlarging it. A shape can be made larger by multiplying all of its lengths by the scaling factor. We can calculate how much larger the shape will be by using the scaling factor. For instance, if a shape is scaled up by a factor of 2, all of the sides will lengthen by the same factor.
Here,
We have to determine the formula for enlargement.
We concluded that New length = original length × scale factor.
When we enlarge a shape by a scale factor, the area of the shape is multiplied by the square of the scale factor. When we enlarge a shape by a scale factor, the volume of the shape is multiplied by the cube of the scale factor.
Hence, the formula for enlargement = New length = original length × scale factor.

How to solve system of equation using elimination method?System of equation can be solved using different method such as elimination method, substitution method and graphical method.
Let's solve the system of equation using elimination method as follows:
11x - 5y = 2
x - 5y = -18
subtract equation(ii) from equation(i) to eliminate the variable y.

Is an example of quadratic inequality?
Answers
The following is an example of a quadratic inequality: x^2 + 2x - 8 > 0.
This is an example of a quadratic inequality because it is an inequality involving a quadratic function (x^2 + 2x - 8) which is of the form ax^2 + bx + c where a, b, and c are constants.
Quadratic inequalities can be solved by factoring the quadratic expression, using the Quadratic Formula, or graphing the inequality. In order to solve a quadratic inequality, it is important to understand the types of solutions that can be expected.
Solutions may include one solution, two solutions, or no solutions. Additionally, when graphing a quadratic inequality, the graph may be a line or a region. To determine which type of graph to use, the type of inequality must be identified (greater than or less than). If the inequality is a greater than or less than inequality, then the graph will be a region. If the inequality is an equal to inequality, then the graph will be a line.
Solving and graphing quadratic inequalities is an important skill in algebra as it allows us to visualize and solve complex problems.

Answers
According to the unitary method, after 2.05 hours value of stock will be equal.
Here we have given that the following value are given in the question they are listed as follows:
Stock 1 has price of stock at 9 A.M is $16.12 and the Rate of increase is $0.12 per hour
Similarly, Stock 2 has price of stock at 12 P.M is $16.87 with the Rate of decrease is $0.07 per hour.
Here first we have to calculate price of stock at 12 P.M, then we get the value as,
=> 16.12 + (0.12 x 3) = 16.48
Now, let us consider that x hours after 12 P.M their price will be same
Then the First consider case of stock 1 as,
=> Price of Stock 1 after x hours from 12 P.M
=> 16.48 + 0.12x
For stock 2, the value is calculated as,
=> Price of Stock 2 x hours after 12 P.M
=> 16.87 - 0.07x
Then we have to equate the price of stock x hours after 12 P.M:
=> 16.48 + 0.12x = 16.87 - 0.07x
When we simplify this one then we get,
=> 0.19x = 0.39
=> x = 2.05

how to know if a riemann sum is an overestimate or underestimate
Answers
In general, if the rectangles are all the same width and if they are placed to the right of the curve, the Riemann sum will be an overestimate of the true area. On the other hand, if the rectangles are placed to the left of the curve, the Riemann sum will be an underestimate of the true.
Another method to determine if a Riemann sum is an overestimate or underestimate, we can compare it to the exact value of the definite integral. If the Riemann sum is larger than the definite integral, it is an overestimate. If the Riemann sum is smaller than the definite integral, it is an underestimate. Additionally, we can also check the sign of the function being integrated and the width of the rectangles. If the function is positive and the width of the rectangles is decreasing, then the Riemann sum will be "an overestimate". If the function is negative and the width of the rectangles is decreasing, then the Riemann sum will be "an underestimate".

the average of the first 4 weights was 5 pounds. the average of the next 11 weights was 20 pounds. what was the overal average of the weights?
Answers
The overall average of the weights is 16.
What is average?The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.
Given that the average of the first 4 weights is 5.
Avg = Total Sum / Total number of weights
Substituting the value of Avg = 5 and Total number of weights= 4 we have:
5 = Sum(4) / 4
Sum(4) = 20
The average of the next 11 weights was 20 pounds.
Substituting the values, we have:
20 = Sum(11) / 11
Sum(11) = 220
The total sum of the 4 weights and the 11 weights is:
Sum = Sum(4) + Sum(11)
= 20 + 220
= 240
The total number of weights are: 4 + 11 = 15
The overall average weight is:
Avg = Sum/ total number of weights
Avg = 240/ 15
Avg = 16

f(x) = x-5 / 3 -x
f^-1(x) = 3x+5 / x+1
Answers
f^-1(x) is the inverse of f(x) as the composite functions f(f^-1(x)) and f^-1(f(x)) are both equal to x.
What is composite functionA function is composite when the co- domain of the first mapping is the domain of the second mapping.
We shall evaluate the functions f(f^-1(x)) and f^-1(f(x)) as follows:
f(f^-1(x)) = [(3x+5 / x+1) - 5] ÷ [3 - (3x+5 / x+1)]
changing division to multiplication;
f(f^-1(x)) = [3x + 5 - 5(x + 1)]/(x + 1) × (x + 1)/[3(x + 1) - (3x + 5)]
(x + 1) is common and will cancel out
f(f^-1(x)) = (3x + 5 - 5x - 5)/(3x + 3 - 3x - 5)
f(f^-1(x)) = -2x/-2
f(f^-1(x)) = x
f^-1(f(x)) = [3(x-5 / 3 -x) + 5] ÷ [(x-5 / 3 -x) + 1]
changing division to multiplication;
f^-1(f(x)) = [3(x - 5) + 5(3 - x)]/(3 - x) × (3 - x)/[x - 5 + (3 - x)]
(3 - x) is common and will cancel out
f^-1(f(x)) = (3x - 15 + 15 - 5x)/(x - 5 + 3 - x)
f^-1(f(x)) = -2x/-2
f^-1(f(x)) = x
Therefore, since composite functions; f(f^-1(x)) = x and f^-1(f(x)) = x, then f^-1(x) is the inverse of f(x).
