The rate at which the distance is decreasing is - 30 centimeters per second. Ravi's distance from the first floor when he stepped on escalator is 1250 centimeters.

The pace at which one quantity changes in relation to another quantity is known as the rate of change function. Simply said, the rate of change is calculated by dividing the amount of change in one thing by the equal amount of change in another.

a. From the table we can observe that as time increases, his distance from the first floor decreases.

The rate at which the distance is decreasing is given by:

Rate = (d2 - d1)/ (t2 - t1)

= (980 - 1070) / (9 - 6)

= -90 / 3

= -30

Hence, the rate at which the distance is decreasing is - 30 centimeters per second.

b. Ravi's distance from the first floor when he stepped on escalator is calculates as:

d - d1 = m(t - t1)

where, m is the rate.

Here, m = -30.

d - 1070 = (- 30) (t - 6)

d = -30t + 180 + 1070

d = -30t + 1250

The time when he stepped on escalator is 0.

d = -30(0) + 1250

d = 1250

Hence, Ravi's distance from the first floor when he stepped on escalator is 1250 centimeters.

Step-by-step explanation:

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.

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:

[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:

[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.

The angle x in a right-angled triangle is 12.8°.

What is a right-angled triangle?

A triangle is said to have a right angle if one of the angles is 90 degrees. Right triangles are those with angles at 90 degrees, which are referred to as right angles.

The diagram shows a right-angled triangle with opposite = 12 units and hypotenuse as 54 units.

To find the angle x, apply the formula -

sin(x) = opposite/hypotenuse

sin(x) = 12/54

x = sin^-1(12/54)

x = sin^-1(2/9)

x = 12.84°

Rounding it to nearest tenth gives x = 12.8°.

Complex numbers and real numbers cannot be directly compared as they are from different number systems.

Complex numbers have both a real and an imaginary component, whereas real numbers only have a real component. However, you can compare the magnitudes (absolute values) of complex numbers with real numbers.

The magnitude of a complex number is the distance from the origin in the complex plane, represented by the absolute value or modulus of the complex number, which is always a positive real number. By comparing the magnitudes of complex numbers, you can determine which one is larger or smaller.

For example, the magnitude of 3 + 4i is 5, and the magnitude of 2 + 3i is 3.5. Therefore, 3 + 4i has a larger magnitude than 2 + 3i.

  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.

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]

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.

The length of the other leg of a right triangle, as per the Pythagoras theorem, is option B: 13.0 cm.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse. The calculation of the other leg of tbe triangle is given as follows.

According to the Pythagoras theorem:

(Hypotenuse)² = (Base)² + (Height)²

As per the question,

The height or the length of a leg of a right triangle is given equal to 11 cm and hypotenuse is given 17 cm. The other leg, or the base can be calculated as:

(Base)² = (Hypotenuse)² - (height)²

b² = (17)² - (11)²

b² = 289 - 121

b² = 168

b = √168

b = 12.96

or b = 13cm.

Thus, the base or the other leg of the right triangle is equal to 13 cm.

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.

The solutions to the different sides and values of square are given below. The length of the side of the square is 6.71m.

Square is a polygon which four equal sides and all angles are right- angles.

Given area of square = 45 m²

     Area = side²

     Side = √Area = √45 = 6.71 m

Therefore side of the square is 6.71m.

41) Negative numbers do not have square roots.

Therefore √-4 is undefined.

42) Option D is correct as it is not a fraction.

43) Any number multiplied by zero is zero.

Therefore (a) is the correct option.

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

Therefore option a is correct.

48) Let the amount of work be W

     For 3 men,

          8 days = W

             1 day = W/8

Now work done by 1 man in one day = (W/8) /3 =W/24

In six days, work done by one man = W/24 * 6 = W/4

Therefore for the work to be completed, the number of men required is 4 (W/4 *4 = W).

Step-by-step explanation:

Taking the given ride lengths for 3 consecutive days and adding them the total number of miles ridden by the rider is 14.67 miles.

On Tuesday, the distance traveled is 1 and 1/2 times further than Monday's distance. This means that the distance traveled on Tuesday is 1.5 times the distance traveled on Monday.

To find the total distance traveled over a period of multiple days, we can add up the distances traveled on each day. This can be done by summing up all the individual distances traveled on each day. This can be done either in fraction or decimal. If the distances are in mixed numbers, it is good to convert them into fractions before adding them. This will give the total distance traveled over the period of multiple days.

On Tuesday, you ride 1 and 1/2 times further than on Monday, which is 3 and 2/3 miles * 1 and 1/2 = 5 and 1/2 miles.

On Wednesday, you ride 1 and 1/4 miles less than on Tuesday, which is 5 and 1/2 miles - 1 and 1/4 miles = 4 and 1/4 miles.

The total number of miles you rode on Monday, Tuesday, and Wednesday is:

3 and 2/3 miles + 5 and 1/2 miles + 4 and 1/4 miles = 13 and 5/6 miles

You can convert the mixed numbers to fraction to find the total miles.

3 and 2/3 miles = (33 + 2)/3 = 11/3 miles

5 and 1/2 miles = (52 + 1)/2 = 11/2 miles

4 and 1/4 miles = (4*4 + 1)/4 = 17/4 miles

So, the total number of miles you rode on Monday, Tuesday, and Wednesday is :

11/3 + 11/2 + 17/4 = (114 + 113 + 172)/12 = 11/3 + 33/4 = (114 + 11*3 + 34)/12 = 44/3 = 14.67 miles

You rode 14.67 miles in total for 3 days.

The answer is B: 1/16

Answer:

Step-by-step explanation:

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.
