Answer:
9.6km / 9600m
Step-by-step explanation
B= 0.5km
L = 0.7km
perimeter of a rectangle = 2(L+B)
= 2( 0.7 + 0.5)
= 2.4km
wire for one round is 2.4km
wire for 4 rounds = 2.4 x 4
= 9.6km wire is required.
Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.
Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
