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:
A. 2 (I can't really see the graph clearly, I think this is right)
Step-by-step explanation:
(1,4)(2,6)
6-4 =2
2-1 =1
2/1 =2
Answer:
88%

0.88*100=88%
Answer:
x =10
Step-by-step explanation:
angles are equivalent
170 = 2x + 6x + 90
170 - 90 = 8x +90 - 90
80 = 8x
10 = x
Answer:
87 seconds
Step-by-step explanation:
1 step = 1 second
87 steps is going to equal 87 seconds
Hope this helps! have a blessed day.
