Answers:(3) True
(4) Num Lock
Explanations:(3) To undo any task in most of the softwares including Blender, CTRL + Z is used. If you want to double check, go to preference -> Input -> Search for undo. You would see CTRL + Z shortcut there for one time undo (as shown in the picture 1 attached.) Hence (TRUE).
(4) As in blender, during the scene creation, the designers usually use top, left, right or bottom view. Blender has the built-in keys set for those views. As you can see in the second image that the Top view is set to NumPad 7 (likewise others set to other numbers). In order to use the those numpad numbers, you must turn on the NumLock! Hence NumLock is the answer.
Answer:
The complete Matlab code along with step by step explanation is provided below.
Matlab Code:
function Req=ParallelR(Number)
Number=input('Please enter the number of resistors: ');
if Number>10 | Number<=0
disp('Invalid input')
return
end
R=0;
for i=1:Number
r=input('Please enter the value of resistor: ');
R=R+1/r;
end
Req=1/R;
end
Explanation:
Parallel resistance is given by

First we get the input from the user for how many parallel resistors he want to calculate the resistance.
Then we check whether the user has entered correct number of resistors or not that is from 1 to 10 inclusive.
Then we run a for loop to get the resistance values of individual resistors.
Then we calculated the parallel resistance and keep on adding the resistance for N number of resistors.
Output:
Test 1:
Please enter the number of resistors: 3
Please enter the value of resistor: 10
Please enter the value of resistor: 20
Please enter the value of resistor: 30
ans = 60/11
Test 2:
Please enter the number of resistors: 11
Invalid input
Test 3:
Please enter the number of resistors: 0
Invalid input
Answer:
name = input("Enter customer name: ")
quantity = int(input("Enter quantity: "))
size = input("Enter size [large-medium-small]: ")
if size == "large":
sales = (quantity / 12) * 13
if size == "medium":
sales = (quantity / 12) * 11
if size == "small":
sales = (quantity / 12) * 8.6
print(name + " ordered " + str(quantity) + " " + size + " ballons")
print("Total sales is $" + str(sales))
Explanation:
*The code is in Python.
Ask the user to enter name, quantity, and size
Check the size using if structure. Depending on the size, calculate the sales using the given cost for for a dozen.
Print the order information and total sales
