The distance that the end of the pendulum travels when it swings is given by the relation D = 27.3 cm

Given data ,

A pendulum of length 18 cm is swinging from a fixed point

Now ,  it swings through an angle of 87°

So , Central Angle = ( s x 360° ) / 2πr

where s is the length of the arc

Now , D = ( θ/360 ) x 2πr

On simplifying , we get

D = ( 87 / 360 ) x 2 ( 3.14 ) ( 18 )

D = ( 0.241667 ) ( 113.04 )

D = 27.3 cm

Hence , the pendulum travels a distance of 27.3 cm

Answer:

The exact volume of the cylinder is 72π cubic centimeters, or approximately 226.19 cubic centimeters to two decimal places.

Step-by-step explanation:

The volume of a cylinder can be calculated using the formula:

[tex]\boxed{V = \pi r^2 h}[/tex]

where:

Given values:

Substitute the given values into the formula and solve for V:

[tex]\begin{aligned} \implies V&=\sf \pi \cdot 3^2 \cdot 8\\&=\sf \pi \cdot 9 \cdot 8\\&=\sf 72\pi \;cm^3\\&= \sf 226.19\; cm^3\;(2\;d.p.)\end{aligned}[/tex]

Therefore, the volume of the cylinder is 72π cubic centimeters, or approximately 226.19 cubic centimeters to two decimal places.

The total area of the composite figure is 17 square centimeters.

Remember that the area of a rectangle is equal to the product between its dimensions.

We can separate the figure into two rectangles, one of these rectangles is of 1cm by 2cm, then its area is:

A = 1cm*2cm = 2cm²

The other rectangle is of 3cm by 5cm, then its area is:

A' = 3cm*5cm = 15cm²

Adding that we get a total of:

total area = 2cm² + 15cm² = 17cm²

The ball's height is 11 meters after approximately 6.83 seconds and 0.17 seconds.

The height of the ball after t seconds is given by the equation h = 1 + 30t - 5t^2. To find all values of t for which the ball's height is 11 meters, we need to solve the equation [tex]1 + 30t - 5t^2 = 11[/tex].

You want to know the amount deposited at 1.5% that will earn the same simple interest in a year as $12,000 deposited at 1.9%.

The interest amount is given by the formula ...

  I = Prt

For the two accounts, the interest and the time are the same, so we have ...

  P1·r1 = P2·r2

  12000·1.9% = P2·1.5% . . . . . . . . . . . equate interest amounts for t=1

The area of the regular decagon with a radius of 14 units is approximately [tex]195.7 unit^{2}[/tex]

To find the area of a regular decagon, we need to know either the side length or the apothem (the perpendicular distance from the center to a side). In this case, you have provided the radius of the decagon, which is 14 units.

For a regular decagon, the apothem (a) is related to the radius (r) by the formula:

[tex]a = r * cos(\pi/10)[/tex]

Let's calculate the apothem using the given radius:

[tex]a = 14 * cos(\pi/10) =12.149[/tex]

Now, we can calculate the area (A) of the regular decagon using the formula:

[tex]A = (5/2) * a^2 * tan(\pi/10)[/tex]

[tex]A = (5/2) * (12.149)^2 * tan(\pi/10) =195.7[/tex]

Step-by-step explanation:

After considering the given details we conclude that the height of the picture frame is 12, under the condition that the diagonal of a picture frame is 18 inches the base of the picture frame is 12.

The height of the picture frame can be evaluated applying  the Pythagorean theorem. The Pythagorean theorem projects that in a right triangle, the square of the length of the hypotenuse (the diagonal of the picture frame) is equivalent to the summation of the squares of the lengths of the other two sides (the height and base of the picture frame).

Therefore , in this case, we have a right triangle with a hypotenuse of 18 inches and a base of 12 inches. We can evaluate for the height as follows:
height²+ 12² = 18²
height² = 18² - 12²
height² = 144
height = √(144)
height = 12
Hence, the height of the picture frame is 12 inches rounded to the nearest tenth.

The inequality representing the amount Jeremiah spends on dinner daily is x ≥ $14.50. Two examples of amounts Jeremiah might spend are $16.75 and $22.00.

1. To represent the amount Jeremiah spends on dinner daily, we can use the inequality symbol "≥" (greater than or equal to) since it says "at least." Let's use the variable x to represent the amount.

2. The inequality representing the amount Jeremiah spends is x ≥ $14.50.

3. Example 1: Jeremiah might spend $16.75 on dinner, which satisfies the inequality since $16.75 is greater than $14.50.

4. Example 2: Jeremiah might spend $22.00 on dinner, which also satisfies the inequality as $22.00 is greater than $14.50.

Answer:

31 years

Step-by-step explanation:

A = P(interest rate)^number of years (n)

if the money is to quadruple, A = 4 X 22,000 = 88,000.

P = investment amount = 22,000.

interest rate is 4.5%. so we have the whole (100%) + 4.5% = 1.045%.

n is number of years.

22,000 (1.045)^n = 88, 000

divide both sides by 22, 000:

(1.045)^n = 4

take logs for both sides:

log (1.045)^n = log 4

simplify using log laws (by bringing down the n):

n log (1.045) = log 4

divide both sides by log (1.045):

n = (log 4) / log (1.045)

= 31.49 (31 years to nearest year)

Median: 212

Mode: 212

The median and mode of the data set are 273 and 212 respectively.

The median is the value that splits the mathematical numbers or expressions in half. The median value is the middle number of data points. To find the median first arrange the data points in ascending order.

To find the median, we need to arrange the numbers in order from least to greatest:

3, 4, 5, 212, 212, 334, 414, 823

There are 8 numbers in total, so the median is the average of the two middle numbers, which are 212 and 334.

Median = (212 + 334)/2 = 273
