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
When you do the 25. You have to do the 0 so it would be 0.025
The amount of sod jayden needs is 4100 sq ft because you multiply 50 by 70 and get 3500 then you add that to 600 which you get that from 30 x 20 and your answer will be 4100.
Sorry I’m not sure about the answer but good luck
Answer:
Yes
Step-by-step explanation:
If we need to find the distance between two points on a number line, we subtract one of the points from the other. We then take the absoulte value of the difference. You done this right.
