The pendulum will swing at the velocity of 3.06 m/s at the bottom of the swing.
What is velocity?Velocity is the rate of change of position of an object, usually measured in meters per second (m/s). It is a vector quantity, which means it has both magnitude and direction. Velocity is an essential notion in physics since it is used to describe motion and is one of the fundamental principles of classical mechanics. It is connected to other notions such as acceleration, momentum, and force. Velocity is a measure of how rapidly an item moves in a specific direction, and it is computed by dividing the distance travelled by the time it takes for the object to traverse that distance.
The speed of the pendulum at the bottom of its swing can be calculated using the formula:
v = √(2gh)
where v = velocity, g = gravitational acceleration (9.8m/s2), h = height (1.22m)
Therefore, the speed of the pendulum at the bottom of its swing is:
v = √(2*9.8*1.22)
v = 3.06 m/s

Step-by-step explanation:
a) Bus leaves Church Street at 07:59. Bus Station times are at 07:40, 08:30 and 9:20. 07:40 is 9 minutes is earlier then 07:59 (07:59 > 07:40) therefore its 08:30.
Answer: 08:30.
b) If Jo has to get there at 8.30am, the time of the latest bus she can take is the one at 08:44. 07:04 is too early and so is 07:54.
Answer: 07;54
c) Lets use the bus that comes to School Road at 08:04 to make it easier. The bus will arrive at 08:30 at Bus Station. Focus on the minutes, not hours. 30 - 4 = 26, meaning it will take 26 minutes from School Road to the Bus Station.

Point T is at (-2,5). What are the coordinates of point T after R y axis o R axis
The coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5). The solution has been obtained by using the concept of reflection.
What is reflection?
In geometry, a reflection is referred to as a flip. In a reflection, the shape is reflected. An image will reflect over a line known as the line of reflection.
We are given a point T(-2, 5)
In order to find the coordinates of the reflection of point in the y-axis, we need to change the sign of abscissa i.e., x-coordinate and retain the ordinate i.e., y-coordinate.
So, we get the image of (-2 , 5) as (2, 5)
Thus, the coordinates of point T' after Ry-axis is (2, 5).
When we reflect across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse.
So, we get the image of (-2 , 5) as (-2, -5).
Thus, the coordinates of point T' after Rx-axis is (-2, -5).
Hence, the coordinates of point T' after Ry-axis is (2, 5) and the coordinates of point T' after Rx-axis is (-2, -5).

Levin Furniture buys a living room set with a $5,800 list price and a 50% trade discount. Freight (FOB shipping point) of $45 is not part of the list price. What is the delivered price (including freight) of the living room set, assuming a cash discount of 3/10, n/30, ROG? The invoice had an April 8 date.

What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
List Price = $5800
Trade discount = 50%
So, Price after discount
= $5800 - 50% x $5800
= 5800- 2900
= $2900
if Levin pays within 10 days he will have a discount of 3%, So,
3% x $2900
= $87
Thus, the Delivered price = $2900 -$87+ freight charges ( shipping)
= $2900 -$87 + $45 =$2858

The mass of a radioactive substance follows a continuous exponential decay model, with the decay rate parameter 4% per day. A sample of this radioactive substance has an initial mass of 2.05 kg. Find the mass of the sample after four days. Round your answer to two decimal places.
The mass of the sample after four days is 1.75 kg.
How to find the mass of the sample after four days?The decay rate for a radioactive substance follows the exponential decay formula:
m(t) = m₀ * e^(-kt),
where m₀ is the initial mass, m(t) is the mass at time t, k is the decay rate parameter, and e is the base of the natural logarithm.
Given that the initial mass of the sample is 2.05 kg and the decay rate parameter is 4% per day, the formula becomes:
m(t) = 2.05 * e^(-0.04t).
To find the mass after four days, we substitute t = 4:
m(4) = 2.05 * e^(-0.04 * 4)
m(4) = 1.75 kg

The number of solutions that the system of equations has is given as follows:
The system of linear equations represented in the graph have
No solutions.
How to obtain the number of solutions?The first step in obtaining the number of solutions of the system of equations is obtaining the linear function that represents each line.
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope.
b is the y-intercept.
here, we have,
The first line goes through these following points:
(0,3) and (3,4).
The slope is given by change in y divided by change in x, hence:
slope = 3
When x = 0, y = 3,
hence the intercept is of b = 3

y = 3x - 3
The second line goes through these following points:
(0,-2) and (3,-1).
Hence the slope is of:
m = 3

A study suggest 14.7% of all four digit personal identification numbers, or PIN codes, have a repeating digits format such as 2525. Assuming this to be true, if the PIN codes of four people are selected at random, what is the probability that at least one of them will have repeating digits?
The probability that at least one of the codes will have repeating digits is 0.4712.
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Here, The probability of a pin being repeated is 14.7%
⇒ 14.7/100
After Eliminating the decimal point;
⇒ 14.7/100 = 147/1000
Hence,
The probability that a pin, if selected will have a repeating digit format = 147/1000
The probability of a pin not having repeating digits format is,
⇒ 1 - 147/1000
⇒ 853/1000
If four codes are selected at random (without replacement), the probability that all four of the codes will not have repeating digits format is,
⇒ (853/1000) x (852/999) x (851/998) x (850/997)
