Rearrange equation.h=-16t^2-6t+110 h = 0 at the ground. divide both sides of the equation by (-2) to yield: 0 = 8t^2+3t - 55 and use quadratic equation h=<span>-b±√(b2 - 4ac)</span> 2awhere a = 8, b= 3, c=-55 Substitute: [-3 ± √(9 - 4*8*(-55))] / (16) = [6 ± √(36 + 1760)] / (16) = [6 ± √(1796)] /16 = (6 ± 42.3792)/16. Time can only be positive for this problem...so discard negative answer. = 48.3792/16 = 3.02 seconds
Answer:
$12,000
Step-by-step explanation:
Use the simple interest formula: P = A(1 + rt)
P = final balance (?)
A = starting balance (10,000)
r = interest rate (0.05)
t = years (4)
P = 10,000(1 + 0.05 · 4)
P = 10,000(1 + 0.2)
P = 10,000(1.2)
P = 12,000
