12 by 8 ft. :) If you multiply the perimeter is 96. I hope this helps!
Answer:
4
Step-by-step explanation:
B = (6,5) C = (6,9)
√(x2 - x1)² + (y2 - y1)²
√(6 - 6)² + (9 - 5)²
√(0)² + (4)²
√16
= 4
The common denominator would be 40
104 = -16T2 + 729
16t^2 = 729 - 104 = 625
4t = +/-25
t = +/-6.25
Between 6.25 and 13.5 seconds after he jumps
