 Hello and welcome to the session. In this session, we will discuss a question that says that two fishermen, Jim and Kevin, drive their nets into the sea at a depth of 25 feet and 28 feet respectively. Then, in that case, write an integer for the position of each net related to the sea level, b part, which integer in part a has greater absolute value because whose net is closer to the sea level. Now, before starting the solution of this question, we should know a result. And that is, absolute value of a number is the distance of that number from zero on a number line. And absolute value of a number a is written as absolute value of a, which is equal to the momentum value of a without regard to its sign. Like this, absolute value of a is equal to a f minus a is also equal to, now if we have two integers minus two and minus three and we want to know which decision is closer to zero, then we need the use of absolute value. Now, absolute value of minus two is equal to two, absolute value of minus three is equal to three. Now, we know that absolute value of a number is its distance from zero on a number line. Now, we are getting absolute value of minus two is equal to two and absolute value of minus three is equal to three. That is, the distance of minus two from zero on a number line is two, the distance of minus three from zero on a number line is less than three. That is, the distance of minus two from zero is less than the distance of minus three from zero on a number line is closer to zero. This result will work out as a key idea for solving out the given question. Now, let us start with the solution. Now, in the question, it is given that two fishermen, Jim and Kevin, drop their nets into the sea at a depth of 25 feet and 28 feet respectively. And in the first part, we have to find out an integer for the position of each net relative to the sea level. Now, for solving out this, first of all, let us draw a horizontal line. Now, consider this line to be the sea level and mark it as the point zero. Now, since Jim and Kevin drop their nets into the sea, thus the points 25 will lie below the sea level. Now, where we can see that both of the nets have moved downwards are negative integers. As we know, in real life situation, positive and negative numbers are used to describe the quantities having opposite direction of values are moving above the sea level. That is, if we are having the opposite movement, then in that case, we will use the positive integers. Thus, in this case, as both of the nets are moving downwards, that is, they are moving below the sea level. So, in this case, we will use the negative integers. Now, for the A part, let us draw a table in which the integer for the position of each net related to the sea level is given. Now, in this table, the first column represents the name of the fisherman and the second column represents the integer for the position of the net related to the sea level. Now, where we can see that Jim's net is at a depth of 25 feet in the sea, that is, is at a distance of 25 from zero, that's in downward direction. So, the integer for the position of Jim's net related to the sea level is minus 20 h. Now, in the B part, we have to find that which integer in part A has greater absolute value. Now, using the result which is given in the key idea, now, first of all, we will take the absolute value of minus 25 which is equal to 25 of minus 28 is equal to 28. Now, as 28 is greater than 25, therefore, the absolute value of minus 28 is greater than the absolute value of minus 25. Now, in the C part, we have to find that whose net is closer to the sea level. Now, we will get absolute value of a number given its distance from zero. Now, we have the absolute value minus 25 is equal to 25. Absolute value of minus 28 is equal to 28. Now, as 25 is less than 28, that is, the distance of Jim's net from zero or sea level which is 25 is less than the distance of Kevin's net from zero or sea level which is 28. So, the distance of Jim's net from the sea level is less than the distance of Kevin's net from the sea level, therefore, is closer to the sea level. So, this is the solution of the given question and that's all for this session. Hope you all have enjoyed this session.
