Answer:
x = 5
Step-by-step explanation:
a² + b² = c²
x² + 12² = 13²
x² + 144 = 169
x² = 169 - 144
x² = 25
x = 5

Answer:
5 seconds
Step-by-step explanation:
H= -16t2 + 400
Hit ground
H=0
0 = -16t2 + 400
0 = -16 ( t2 - 25)
-16
t2 -25 = 0
(t + 5)(t - 5) = 0
t + 5 = 0
- 5 -5
t = -5
t - 5 = 0
+ 5 +5
t = -5
t = 5
5 seconds to hit the ground
<span>First, we write an equation to represent that the fencing lengths add up to 568 feet. we call the side of the fence that has three segments of its length x and the side with only two segments y. We write 3x + 2y = 568. We also know that the area of the rectangle is equal to xy, so area = xy. We put y in terms of x using our first equation and find that y = (568 - 3x)/2. We plug this into our area equation and find that area = (568x - 3x^2)/2. To find the maximum we set the derivative equal to 0 and end up with 0 = 284 - 3x. We solve for x and get 94 and 2/3. We then put that into our first equation to find y = 142. So the dimensions that maximize the area are 94 2/3 x 142.</span>
