A = length x width
15,000 = (w + 30) x w
15,000 =

+ 30w
0 =

+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5

. Because distance cannot be negative, the width is -15 + 5

meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
Answer:
D
Step-by-step explanation:
Our parent function:
y = tan x
Let's apply the vertical shift now:
y = 3 + tan x
Now the period. This is a little tricky because we have to remember that the period is equal to π/b, because tangent functions normally have a period of π, and the b is the value placed in front of the x.
In this case, that value would have to be π/4
π/(π/4) = 4
Therefore, our b-value is π/4 and our final equation is as follows:
y = 3 + tan (π/4)x
