1a) If the designer measures the pond and determines that the length of the pond across is 400 feet wide, what is the length of the radius? Show your work.
b) The designer wants to plant new flowers around the pond. How many feet of flowers would she need to plant in this new design? Round to the nearest hundredth. Show your work.
c) The designer wants to determine how much water is covered on the surface once the pond is filled up. She claims that the area would be 160,000 square feet. Is she correct? Justify your answer showing work
Hello,
Let's assume the last digit given by the function last(x).
last(7^0)=1
last(7)=7
last(7^2)=last(49)=9
last(7^3)=last(last(7^2)*7)=last(9*7)=last(63)=3
last(7^4)=1
If the exponent n is 0,4,8,12,.... a multiple of 4 last(7^n)=1
If the exponent n is 1,5,9,13,.... a multiple of 4 + 1 last(7^n)=7
If the exponent n is 2,6,10,14,.... a multiple of 4 + 2 last(7^n)=9
If the exponent n is 3,7,11,15,.... a multiple of 4 + 3 last(7^n)=37
Here exponent is 282=70*4+2
last(7^282)=9
4(square root of 0.0081)
= 4(square root of 81x10^-4
= 4(9x10^-2)
= 36x10^-2
= 0.36
