Answer:
Written in Python
def sums(n):
total = 0
for i in range(1,n+1):
if i%2 == 0:
total = total + i*2
else:
total = total + i
return(total)
Step-by-step explanation:
The function is written in Python
def sums(n):
This initializes total to 0
total = 0
This iterates through the integers that makes up n i.e. 1,2,3.....n
for i in range(1,n+1):
This checks if current digit is even
if i%2 == 0:
If yes, it adds the double of the digit
total = total + i*2
else:
If otherwise, it adds the digit
total = total + i
This prints the calculated sum or total
return(total)
To call the function from main, use the following:
print(sums(n))
Where n is a positive integer. i.e. 
Answer:
D
Step-by-step explanation:
The PERIMETER will be 4/5 of the original if you reduce the sides by 4/5
area will be reduced by 4/5 * 4/5 = 16/25 of original
Answer:
The answer = 8.1841 cm²
Step-by-step explanation:
Sector of area = <u>46⁰</u> pie14²
360⁰
Area of the showed region = 78.6794 - 1/2 × 14 × 14 × sin46⁰
= <u>8.1841cm</u><u>²</u>
