Answer:
The answer is "
"
Step-by-step explanation:
A = area of the pigpen
x = its perpendicular length of the sides of the stone wall
Maximize function:

So, the size of pigpen is = 100 ft by 200 ft that is (perpendicular and parallel to wall), that's why the answer is "
"

Answer:
The total number of possibilities are 60.
Step-by-step explanation:
Given:
There are 6 digits and 3,7,9 are odd ones.
To Find:
How many possibilities are there for the rock's age
Solution:
Here condition is that number should start with odd digit
so there 3 number only as odd(3,7,9)
So it leaves 3 repeating numbers i.e.2
So permutation of 5 numbers with 3 odd numbers
So possible arrangement will be
nPr
n=5 ,r=3
So 5P3=5!/3!
And finally for all possibilities as
=3*(5!/3!)
=3*(20)
=60
Step-by-step explanation:
with the y= 4x +1
they find the first column by replacing x in the function by 0
meaning if x= 0 then y=4(0) + 1 so y=1
for the second column if x =2 then y= 4(2) +1 so y= 9
for the 3rd one if x =4 then y = 4(4)+1 so y = 17
