Add 0.02 by 0.4 and get 0.42 then divide 0.42 by 0.07x and get 6
x=6
if the upper number got power of negative it will go down and the down will go up
So that,
power of 1 can no need to write
Answer:
6
Step-by-step explanation:
38/7=5.42
round the 5.42 to 6
Answer:
390 m (perpendicular to river) x 780 m (parallel to river)
Step-by-step explanation:
Let y be the length of the side parallel to the river, and let x be the length of the sides perpendicular to the river.
The total area and length of fence required are given by:
Rewriting the length of fence as a function of only x:
The value of x for which the derivate of L(x) is zero is the length of x that uses the least amount of fencing:
If x = 390 m, then:
The dimensions that will use the least amount of fencing are 390 m x 780 m
