Answer:
h(t) = -16t2 + 186t + 43
at the ground h = 0
hence; -16t2 + 186t + 43 = 0
solving this quadratic equation using the quadratic formula ; a = -16, b = 186, c = 43 ; x = (-b +-(b2 - 4ac)1/2)/2a
gives t = 11.8 seconds to the nearest tenth (note that the negative root has no practical significance)
Step-by-step explanation:
Answer:
The length of the sides is <u>7 In</u>.
Step-by-step explanation:
Given:
A cube has a surface area of 294 sq. In.
Now, to find the sides.
Let the side be 
Putting the formula of area to get the length of side:


<em>Dividing both sides by 6 we get:</em>

<em>Using square root on both sides we get:</em>

Side = 7 In.
Therefore, the length of the sides is <u>7 In</u>.
