Answer:

Chief Information Security Officer (CISO)

Explanation:

One of the senior executive officers in an organization is the Chief Information Security Officer (CISO). Sometimes referred to as the Chief Security Officer (CSO), the responsibility of the CISO is to ensure the security of an organization's business systems and develop strategies to safeguards these systems against malicious intruders such as hacker and viruses.

This role is a very crucial one in any organization especially those that run on IT infrastructures. Not only do they ensure security, they also work together with certain staff such as security directors and managers in the organization, in order to come up with decisions that will add value to the organization and give it some competitive edge over other organizations.

the volume of two similar solids are 1080cm and 1715cm .if the curved surface area of the smaller cone is 840cm .fond the curved
gavmur [86]

Answer:

A_{big} = 1143.33cm^2

Explanation:

The given parameters are:

V_{small} = 1080

V_{big} = 1715

C_{small} = 840

Required

Determine the curved surface area of the big cone

The volume of a cone is:

V = \frac{1}{3}\pi r^2h

For the big cone:

V_{big} = \frac{1}{3}\pi R^2H

Where

R = radius of the big cone and H = height of the big cone

For the small cone:

V_{small} = \frac{1}{3}\pi r^2h

Where

r = radius of the small cone and H = height of the small cone

Because both cones are similar, then:

\frac{H}{h} = \frac{R}{r}

and

\frac{V_{big}}{V_{small}} = \frac{\frac{1}{3}\pi R^2H}{\frac{1}{3}\pi r^2h}

\frac{V_{big}}{V_{small}} = \frac{R^2H}{r^2h}

Substitute values for Vbig and  Vsmall

\frac{1715}{1080} = \frac{R^2H}{r^2h}

Recall that:\frac{H}{h} = \frac{R}{r}

So, we have:

\frac{1715}{1080} = \frac{R^2*R}{r^2*r}

\frac{1715}{1080} = \frac{R^3}{r^3}

Take cube roots of both sides

\sqrt[3]{\frac{1715}{1080}} = \frac{R}{r}

Factorize

\sqrt[3]{\frac{343*5}{216*5}} = \frac{R}{r}

\sqrt[3]{\frac{343}{216}} = \frac{R}{r}

\frac{7}{6} = \frac{R}{r}

The curved surface area is calculated as:

Area = \pi rl

Where

l = slant\ height

For the big cone:

A_{big} = \pi RL

For the small cone

A_{small} = \pi rl

Because both cones are similar, then:

\frac{L}{l} = \frac{R}{r}

and

\frac{A_{big}}{A_{small}} = \frac{\pi RL}{\pi rl}

\frac{A_{big}}{A_{small}} = \frac{RL}{rl}

This gives:

\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{L}{l}

Recall that:

\frac{L}{l} = \frac{R}{r}

So, we have:

\frac{A_{big}}{A_{small}} = \frac{R}{r} * \frac{R}{r}

\frac{A_{big}}{A_{small}} = (\frac{R}{r})^2

Make A_{big} the subject

A_{big} = (\frac{R}{r})^2 * A_{small}

Substitute values for \frac{R}{r} and A_{small}

A_{big} = (\frac{7}{6})^2 * 840

A_{big} = \frac{49}{36} * 840

A_{big} = \frac{49* 840}{36}

A_{big} = 1143.33cm^2

<em>Hence, the curved surface area of the big cone is 1143.33cm^2</em>

Write a function maxTemp which takes a filename as string argument and returns the maximum temperature as float type for the wee
Alenkinab [10]

Answer:

#section 1

def maxTemp(filename):

   import pathlib

   f = pathlib.Path(filename)

   f.exists()

   if f.exists():

       f = open(filename, "r")

#section 2

       next(f)

       res = [int(sub.split(',')[1]) for sub in f]

       maxdata = (res[0])

       for i in range(len(res)-1):

           if maxdata < res[i]:

               maxdata = res[i]

       

       index = res.index(maxdata)

       f.close()

 #section 3  

       li = []  

       a = open(filename, "r")

       for line in a:

           line = line.strip()

           li.append(line)

   

       

       a.close()

       return (li[index+1])

   else:

       return -1

print(maxTemp("new.csv"))

Explanation:

#section 1:

The function maxTemp is defined. We import pathlib in other to check if the file exists, if it does we carry on with opening the file and if it doesn't the program returns -1.

#section 2:

We start splitting the sub-lists from the second line i.e <em>next(f)</em>. For each line we take the second index element and convert it to an integer.

<em>res = [int(sub.split(',')[1]) for sub in f] </em>

The maximum number is gotten by using the if statement to compare all elements in the list.  The index of the maximum item in the list is collected.

the file is then closed.

#section 3  :

The file is re-opened and all the lines are striped and passed into a new list and the index recovered from section 2, is used to get the day with the highest temperature and the line is returned.

What is a method whereby new problems are solved based on the solutions from similar cases solved in the past?
mario62 [17]

Answer:

"Case-Based Reasoning" is the answer for the above question.

Explanation:

  • Case-Based Reasoning is a process of decision-making theory in which the new problems were solved based on the previously solved problem.
  • It is used in artificial intelligence and robots. This helps to make any AI and robots to do the work and take decisions on its own.
  • The theory is used to make any computer that behaves like humans. It can take decisions like a human.
  • The above question asked about the method by which the new problem is solved on behalf of the old problem. Hence the answer is "Case-Based Reasoning".
