Accessing using names In this exercise, you will access data that tracks an account over time. This account consists of wealth from both cash and equities. The data is supplied in a DataFrame named ledger with the index set to dates, represented as strings. The data looks like this: Cash Securities Balance 2020-10-01 0.0 -300.0 1222.0 2020-10-02 300.0 -200.0 1322.0 2020-10-03 -100.0 700.0 1922.0 Instructions 1/3 35 XP

2. Select cash and securities for October 3rd.
Select the balances for October 1st and 3rd.
3. Use slicing to select all columns for October 1st.
Use slicing to select the balance for all dates.

Write a program that inserts the digits of an integer into an array in originalorderfollowed by reverse order. first, promptthe user to enter a positive integer(> 0). determine the number of digits of the integer. create a dynamically allocated integer arrayof a size twice the number of digits.now insert the digits in original order which will occupy half of the array. then, insert the digits in reverse order.finally, output thedigits in thearray.use at least two functions to organize your program.

Select the correct answer. which step can possibly increase the severity of an incident? a. separating sensitive data from non-sensitive data b. immediately spreading the news about the incident response plan c. installing new hard disks d. increasing access controls

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
