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

In order to make the stream of water from a garden hose approximate a sine curve, the nozzle of the hose should be moved in an up-and-down motion.

The reason is because a sine curve is a smooth wave-like pattern that oscillates between positive and negative values. If the nozzle is moved up and down, it will cause the water to be released in a similar wave-like pattern, creating a stream that approximates a sine curve. This is due to the nozzle moving in a sinusoidal motion, which causes the water to be released in the same motion. This kind of motion is known as a harmonic motion, and it's the same motion that causes a wave to have a sinusoidal shape.

What will be the area of triangle if its length and breadth is 14cm and 7cm?

Answers

The area of the triangle would be 49 cm².

Area of a triangle = (length x breadth)/2

Area of the triangle = (14cm x 7cm)/2

Area of the triangle = (98cm)/2

Area of the triangle = 49 cm²

The area of a triangle can be calculated by using the formula (length x breadth)/2. In this scenario, the length and breadth of the triangle is 14cm and 7cm respectively. Therefore, the area of the triangle can be calculated by using the formula. The area of the triangle would be (14cm x 7cm)/2 = (98cm)/2 = 49 cm². Hence, the area of the triangle with the given length and breadth would be 49 cm².

use pascal’s triangle to expand (m+4)^4

Answers

Using Pascal's triangle we can find the binomial coefficient, by which we get 1m^4 + 16m^3 + 96m^2 + 128m + 256

What is pascal's triangle?

Pascal's triangle is a triangular array of numbers in which each number is the sum of the two numbers directly above it. It is named after the French mathematician Blaise Pascal, who studied its properties in the 17th century. The rows of the triangle are numbered starting from 0, and the first number in row n is always 1. The other numbers in row n are the sum of the corresponding number in row n-1 and the number directly above it. The nth number in the kth row of Pascal's triangle is denoted by C(n,k) and it is called binomial coefficient, it is also denoted by nCk. It is used in many areas of mathematics, particularly in combinatorics and algebra, and it can be used to expand binomial expressions using the binomial theorem.

The binomial theorem states that for any non-negative integer n and any binomial expression (a+b)^n, the expansion is given by:

(a+b)^n = C(n,0)a^n*b^0 + C(n,1)a^(n-1)*b^1 + C(n,2)a^(n-2)b^2 + ... + C(n,n)a^0b^n

where C(n,k) = n!/(k!(n-k)!) is the binomial coefficient, which can be found using Pascal's triangle.

Using this theorem:

(m+4)^4 = C(4,0)m^44^0 + C(4,1)m^34^1 + C(4,2)m^24^2 + C(4,3)m^14^3 + C(4,4)m^0*4^4

Using Pascal's triangle we can find the binomial coefficient:

C(4,0)=1, C(4,1)=4, C(4,2)=6, C(4,3)=4, C(4,4)=1

So the expanded form of (m+4)^4 is:

1m^4 + 4m^34 + 6m^24^2 + 4m4^3 + 14^4

find the scale factor

Answers

Answer:

[tex]\dfrac{2}{3}[/tex]

Step-by-step explanation:

Method 1

To find the scale factor of the dilation of a figure, simply divide the x-value (or y-value) of a vertex of the dilated image Q'R'S'T' by the x-value (or y-value) of the corresponding vertex of the pre-image QRST.

[tex]\implies \sf Scale\;factor=\dfrac{x_{Q'}}{x_{Q}}=\dfrac{-2}{-3}=\dfrac{2}{3}[/tex]

[tex]\implies \sf Scale\;factor=\dfrac{y_{T'}}{y_{T}}=\dfrac{4}{6}=\dfrac{2}{3}[/tex]

Therefore, the scale factor is 2/3.

Method 2

To find the scale factor of the dilation of a figure, first find the lengths of corresponding sides using the distance formula.

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Distance between two points}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two points.\\\end{minipage}}[/tex]

From inspection of the given diagram:

Q = (-3, 9)R = (3, 6)

[tex]\implies QR=\sqrt{(x_R-x_Q)^2+(y_R-y_Q)^2}[/tex]

[tex]\implies QR=\sqrt{(3-(-3))^2+(6-9)^2}[/tex]

[tex]\implies QR=\sqrt{(6)^2+(-3)^2}[/tex]

[tex]\implies QR=\sqrt{36+9}[/tex]

[tex]\implies QR=\sqrt{45}[/tex]

[tex]\implies QR=3\sqrt{5}[/tex]

From inspection of the given diagram:

Q' = (-2, 6)R' = (2, 4)

[tex]\implies Q'R'=\sqrt{(x_{R'}-x_{Q'})^2+(y_{R'}-y_{Q'})^2}[/tex]

[tex]\implies Q'R'=\sqrt{(2-(-2))^2+(4-6)^2}[/tex]

[tex]\implies Q'R'=\sqrt{(4)^2+(-2)^2}[/tex]

[tex]\implies Q'R'=\sqrt{16+4}[/tex]

[tex]\implies Q'R'=\sqrt{20}[/tex]

[tex]\implies Q'R'=2\sqrt{5}[/tex]

To find the scale factor of dilation that maps QRST onto Q'R'S'T', divide the length of Q'R' by the length of QR:

[tex]\implies \dfrac{Q'R'}{QR}=\dfrac{2\sqrt{5}}{3\sqrt{5}}=\dfrac{2}{3}[/tex]

Therefore, the scale factor is 2/3.

Use the explicit rule given to write the first three terms for each sequence. F(n)=16+(1/2)(n-1)

Answers

From the explicit rule the first three terms of sequence is 16, 16.5, 17.

What is the explicit rule?The explicit formulae for L-functions are relationships introduced by Riemann for the Riemann zeta function between  the sums over complex number zeroes of an L-function and sums over prime powers.The difference between each consecutive term in an arithmetic sequence is constant. An explicit formula for an arithmetic sequence is a = d (n - 1) + c, where d is the common difference between consecutive terms and c = a1.

Here given,

F(n) = 16+(1/2)(n-1)

We have to find first three terms.

F(1) = 16 + (1/2)(1-1)

      = 16 + 1/2 x 0

      = 16

F(2) = 16 + (1/2) (2-1)

       = 16 + 1/2

       = 16 + 0.5

       = 16.5

F(3) = 16 + (1/2) (3-1)

      = 16 + 1/2 x 2

      = 16 + 1

      = 17

So the first three terms in the sequence is 16, 16.5, 17 with common difference of .05.

An equation also has two sides, the let hand side and the right hand side.

Solving the two equations simultaneously we have:

-9x + 4y = 8 --- (1)

-3x - y = 4 --- (2)

Multiply 2 by 3 and subtract from (1) as shown below

-9x + 4y = 8

How do you find the domain and range of a function in Class 12?

Answers

In Class 12, to find the domain and range of a function, you can use the following steps:

Domain: The domain of a function is the set of all input values for which the function is defined. To find the domain of a function, you need to look at the function and identify any values of x that would make the function output undefined. These values of x are not in the domain of the function.

For example, if the function is f(x) = 1/x, the domain of the function is all real numbers except 0, because dividing by 0 is undefined. In this case, the domain of the function is (-∞,0) U (0,+∞)

Range: The range of a function is the set of all possible output values of the function. To find the range, you can look at the function and identify any restrictions on the output values.

For example, if the function is f(x) = √x, the domain of the function is all non-negative real numbers, because √x is only defined for non-negative values of x. In this case, the range of the function is [0,+∞)

Note that some functions may have more complex expressions, in such cases, you may have to use algebraic methods to find the domain and range.

What does a 0.5 Pearson correlation indicate?

When a correlation coefficient's magnitude is between 0.5 and 0.7, it means that the variables are moderately correlated. Low correlation between the variables is indicated by correlation coefficients with magnitudes between 0.3 and 0.5.

In this equation, x stands for price, and y for sales.

-22.7x+130.3

The slope indicates the number of units that the sales would change by if we raised the price by one unit. Since our slope is -22.7, this indicates that a 1 unit price increase would result in a 22.7 decrease in sales.

The scatterplot's points are all intersected by the line of best fit, as can be seen. We can also calculate the Pearson correlation coefficient, which gives us -0.998, to add to the evidence. This suggests a very adverse relationship.

For this item we will just need the equation for the line of best fit and the data that has been given in the problem. For the actual sales, we will just refer to the given while we will compute for the predicted sales using the line of best fit.

Cross section of a cone:

A cross section is a representation of a shape's axis of symmetry intersected by a plane. When a plane cuts a solid, such as a cone, cylinder, or sphere, it creates a shape known as a cross-section. Depending on how the plane cuts the cone, the cross-section of a solid, such as a cone, can be a circle, a parabola, or a triangle.

When a cone's cross-section is split horizontally, it is circular.

When a cone is cut vertically, its cross-section is an isosceles triangle, and this plane slices through the center of the cone.

When a cone is cut vertically, the cross-section is parabolic except for the plane running through the center.

44) When y = 15, x = 3

   For direct variation, y =kx

so k = y/x =15/3 = 5

When x=5, y = kx =5*5 = 25

Therefore (a) is correct.

45) For inverse variation

   MN = k

  Given 5*3 = k

k=15

When M = 10 , N = k/M = 15 /10 = 3/2

What is the motion of displacement?

Answers

Displacement is the change in the position of an object relative to a reference point over a period of time.

It is usually represented by a vector quantity and is measured in meters (m). The formula for displacement is displacement = final position - initial position. Mathematically, displacement is denoted by s and is equal to the final position (x2) minus the initial position (x1), or s = x2 - x1. As an example, if a person walks a path of length 10 meters, starting at the origin (x1 = 0) and ending at x2 = 10, then their displacement would be s = 10 - 0 = 10 meters. To calculate displacement, we need to know the initial and final positions of the object, and the direction in which it moves.For example, if an object moves from position 5 m to position 10 m, the displacement is 5 m. This can be calculated by subtracting the initial position (5 m) from the final position (10 m). The result is 5 m, which is the displacement of the object.

What happens when the base of an exponential function is negative?

Answers

Answer:

  in ℤ, successive values alternate signs

Step-by-step explanation:

You want to know what happens when the base of an exponential function is negative.

Powers of a negative number

Consider the exponential function ...

  y = a·b^x

For b < 0 and integer values of x, the signs of the corresponding values of y will alternate.

Example

  y = 2·(-1)^x

A table of values will be ...

  [tex]\begin{array}{ccccccc}x&-1&0&1&2&3\\y&-2&2&-2&2&-2\end{array}[/tex]

Roots of a negative number

For non-integer values of x, the values of y become more complicated. For fractional values of x, where x has an even denominator, the equation does not produce a real value. Instead, you get a complex number.

For fractional values of x where x has an odd denominator, the power is defined, and the sign will depend on whether the numerator is even or odd.

For irrational values of x, the function value in general is complex.

Of course, there are an infinite number of rational numbers between any pair of numbers on the number line, so the graph will have both positive and negative values, but will not be continuous. The attached graph can give you the idea. It is not in any way a complete graph of the function, but plots selected values.

Additional comment

The second attachment shows one of the uses of an exponential factor with a negative base. It creates the alternate signs of the series expansion of the sine function. Only whole number exponents are used in this case.

You have 47 total coins for a total of $9.95. You only have quarters and dimes. Choose the two equations that make up the system of equations that represents this situation.

Answers

One equation that represents the total value of the coins in cents is:

0.25x + 0.10y = 995

where x is the number of quarters and y is the number of dimes.

Another equation that represents the total number of coins is:

x + y = 47

These two equations make up a system of equations that can be used to find the number of quarters and dimes that add up to $9.95 and have a total of 47 coins.

Answer:

[tex]\begin{cases}x+y=47\\0.25x+0.1y=9.95\end{cases}[/tex]

Step-by-step explanation:

To solve this problem, we can create and solve a system of equations.

Define the variables:

Let x be the number of quarters.Let y be the number of dimes.

Values of the coins:

The value of a quarter is $0.25.The value of a dime is $0.10.

Given there are a total of 47 coins:

[tex]x+y=47[/tex]

Given there is a total of $9.95 in quarters and dimes:

[tex]0.25x+0.1y=9.95[/tex]

Therefore, the system of equations that represents the problem is:

[tex]\begin{cases}x+y=47\\0.25x+0.1y=9.95\end{cases}[/tex]

To solve the system of equations, rewrite the first equation to isolate y:

[tex]y=47-x[/tex]

Substitute this into the second equation to eliminate y:

[tex]0.25x+0.1(47-x)=9.95[/tex]

Solve the equation for x to find the number of quarters:

[tex]\begin{aligned}0.25x+0.1(47-x)&=9.95\\0.25x+4.7-0.1x&=9.95\\0.15x+4.7&=9.95\\0.15x&=5.25\\x&=35\end{aligned}[/tex]

Therefore, there are 35 quarters.

Substitute the found value of x into the first equation and solve for y:

[tex]\begin{aligned}35+y&=47\\y&=12\end{aligned}[/tex]

Therefore, there are 12 dimes.

The expression that represents the perimeter of the triangle is 3x

How to determine the perimeter of the triangle

From the question, we have the following parameters that can be used in our computation:

Side length = x

Triangle type = equilateral triangle

The perimeter of an equilateral triangle can be calculated as

P = 3 * side length

substitute the known values in the above equation, so, we have the following representation

P = 3 * x

So, we have

P =3x

Hence, the perimeter expression is 3x

What is Sequence?

A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts.

For example, 3, 7, 11, 15, ... is a sequence as there is a pattern where each term is obtained by adding 4 to its previous term.

Given:

The first term of a sequence is 4.

1. let the common ratio 2.

Then, second term= 4 x 2= 8

third term = 8 x2 =16

fourth term = 16 x 2= 32

So, the sequence is 2, 8, 16, 32..

2. let the common ratio 4.

Then, second term= 4 x 4 = 16

third term = 16 x 4 = 64

fourth term = 64 x 4 = 256

So, the sequence is 4, 16, 64, 256.

According to angle symmetry, the value of x=125°

What is an example of an alternate angle?

The two parallel lines intersected by a transversal form alternate angles. Consider the following figure, where EF and GH are two parallel lines. The transversal line RS intersects EF at L and GH at M. If a transversal cuts two parallel lines, the alternate angles are equal.

Since, AK and BL are parallel lines.

Hence,

∠ADC=∠BED=72°

∠EIH=∠DHG=55°

∠DHG+∠GHK=180°

∠GHK=180°-55°

Value of X is 8.

What is rectangle?

A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°.

Given,

Figure OUTD is a rectangle.

Each angle in a rectangle measures 90 degrees.

Therefore,

(7X + 2) + 4X = 90

7X + 2 + 4X = 90

11X + 2 = 90

Subtract 2 from both sides of the equation

11X = 88

Divide both sides of the equation by 11

X = 8.

Hence, 8 is the value of x.
