If the side of the square is a it becomes 1.2a after the increase and its area becomes 1.44a². So the increase is 1.44-1=0.44 or 44%.
<span>Tan(x) = sin(x) / cos(x). Therefore, tan(x) pi/2 = 1/0, which doesn't exist. Imagine that, instead of 0, it's a number incredibly close to 0. The smaller the number in the denominator, the bigger the outcome. Therefore, we can think of 1/0 as infinity, or approaching infinity as one gets closer to 1/0. This is the same result approaching from the negative side, only it's negative infinity. If x=0, it's 0/1 instead (sin 0=0, cos 0=1). Anything divided by 1 is itself, so as x approaches 0, so does f(x).</span>
Answer:
Step-by-step explanation:
Given
total of 1200 ft of fence is available
Suppose rectangular pasture has following dimension as shown in figure.
total perimeter
Area of rectangle is
![A=2[300 b-\frac{3}{4}b^2]](https://tex.z-dn.net/?f=A%3D2%5B300%20b-%5Cfrac%7B3%7D%7B4%7Db%5E2%5D)
For maximum area, differentiate A w.r.t b
so 
so area is
