Answer:
1.58
Step-by-step explanation:
Okay. We're solving for t because we need to know how many seconds. From the problem, we know the height (10), but we don't know when that height happens.
We can factor by multiplying -16 by 61 first to get -976 and see what multiplies to get -976 AND adds to get -7 at the same time. But we can also use the quadratic formula because, let's be honest, factoring can be a lot of extra work.
Plug both the plus and the minus versions into your calculator and...
There's no such thing as negative time, so -2.02 is automatically disqualified, leaving 1.58 as the answer.
Hope this helps, let me know if I missed anything!

This is an answer I wrote last year check it out I have it in my progress
The equation would be 2n x 2 = 3n - 1/2.
So, combine like terms to make it 4n = 3n - 1/2. Subtract to get n = -1/2.
Your answer is -1/2.
Eh that ones hard you sure thats all the ansers
