Answer: 1.4 seconds
<u>Step-by-step explanation:</u>
The equation is: h(t) = at² + v₀t + h₀ where
- a is the acceleration (in this case it is gravity)
- v₀ is the initial velocity
- h₀ is the initial height
Given:
- a = -9.81 (if it wasn't given in your textbook, you can look it up)
- v₀ = 12
- h₀ = 3
Since we are trying to find out when it lands on the ground, h(t) = 0
EQUATION: 0 = 9.81t² + 12t + 3
Use the quadratic equation to find the x-intercepts
a=-9.81, b=12, c=3

Note: Negative time (-0.2) is not valid

-y=-3 y = 3
x=13-(3*3)
x=13-9
x =4
I think this was ur question Rachel bought 1,500 shares of Cawh Consolidated Bank at a price of $24.85 each. As the price climbed, she sold off parts of her holdings. She sold off 250 shares at $28.32 apiece, she sold 800 of her shares at $33.60 apiece, and she sold off the remainder of her shares at $39.94 apiece. If Rachel's broker charges a commission of $65 per $1,000 of stock bought or sold, how much profit did Rachel make, to the nearest dollar?
I think the answer is 8,859? I don't know what the question was, but I think that's it. Hope this helps. c;
