After you cut off 6 pieces, the rope is 18.25 inches long
B.) 3.250*106 days
I figured it out!! Yay!
You take 7.8 and divide it by 24 which will get you 0.325
In order to get it match one of the options, multiply it by 10 (which will add 1 to 105!) Leaving you 3.25*106
1 11 21 31 41 51 61 71 81 91
Answer:
1 and 37/8 feet
Step-by-step explanation:
We set h(t) to 76 because we want to know when the ball will be at 76 feet high.
So, we have 76=-16t^2+90t+2. When we subtract 76 from both sides, we get -16t^2+90t-74=0, and when you mutiply the equation by -1 (so that x^2 has a positive coefficient, which makes things easier), we get 16t^2-90t+74=0.
We notice that each separate monomial has a common factor, 2, so we can take that out and make it 2(8t^2-45t+37) = 0. Factoring the quantity in the parentheses gives us 2(t-1)(8t-37) = 0.
Using Zero Product Property, we can set the two factors in parentheses to 0 (the 2 isn't really relevant so we don't need to worry about it). This gives us t-1=0 and 8t-37=0. Solving these two equations gives us t = 1 foot or t = 37/8 feet.
