Because -2.15 has minus before the number. And all the number have + before it. i.e +2.15. Minus is the opposite of plus so -2.15 and 2.15 are opposites
Answer:
The period is 1
Step-by-step explanation:
The given trigonometric function is;
.
To determine the period of this function, we calculate the length of the interval on which the graph completes one full cycle.
We can see from the graph that; the function completes one full cycle on the interval [0,1].
Hence the period is 1.

Step-by-step explanation:
<span>The fence shape would be 2 identical smaller rectangular plots by placing a fence parallel to one of the field's shorter sides.
______
| </span>|
|______| long=L
| |
|______|<span>
short= S
From the pic, you can see that you need to build 3 short fences and 2 long fences. The equation would be:
600= 3S + 2L
2L= 600-3S
L= 300-1.5S
The area equation would be:
A= S*L
A= S* (</span>300-1.5S)
A= 300S- 1.5S^2
The maximum area equation would be:
A'= 300- 3S=0
3S= 300
S=100
The long side would be
L= 300-1.5S
L= 300- 1.5(100)= 150
The maximum area would be:
A= S*L= 100*150= 150000 ft^2
