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)
Answer:f
Step-by-step explanation:
Answer: $140
Step-by-step explanation:
1/4 × 560 to buy a coat
= 0 25 x 560 = $140
Remaining balance after purchase of coat will be $560 - $140 = $420
Next, he uses 2/3 of $420 for present
2/3 × 420
0.667 x 420
= $280 for present
Alice's balance will be remaining balance after purchase of coat - money for present
= $420 - $280
=$140
I hope this is clear, please mark as brainliest answer. Thank you.
For slightly greater clarity, write this expression as
sqrt(6x^8y^9) 6x^8y^9
-------------------- This is equivalent to sqrt[ -------------------- ]
sqrt(5x^2y^4) 5x^2y^4
Reduce the quantity inside the square brackets, obtaining:
6*x^6*y^5
sqrt[ ---------------- ]
5
This simplifies as follows: sqrt[ 6/5 ] * [ x^3 * y^(5/2)
which can be simplified even further if you wish.
